On-page SEO: The complete guide to on-page SEO

Getting your on-page SEO right is a crucial part of organic search engine optimisation (SEO). It’s the foundation of your website’s visibility, helping you secure those all-important high rankings on Google.

To make sure you’re covering all the on-page essentials, we’ve put together this complete guide – breaking down the key factors that can boost your rankings and improve your website’s performance.

Before we dive into the details, let’s start with the basics:

What is on-page SEO?

On-page SEO is the process of optimising different elements on a web page to give it the best possible chance of being indexed by Google and ranked highly in searches made by your target audience.

How is on-page SEO different from off-page and technical SEO?

While on-page SEO focuses on optimising content and structure within your site, off-page SEO is all about external factors that influence rankings – like backlinks, brand mentions, and social media presence.

Technical SEO, on the other hand, ensures that your site is easy for search engines to crawl and index, improving factors like site speed, mobile-friendliness, and overall usability.

Want to rank on page one of Google?

If so, on-page SEO needs to be a priority.

Google’s search algorithm considers over 200 ranking factors, from page-level elements to domain authority and even external influences like brand recognition. While you can’t control everything, you can take charge of your on-page SEO, making improvements that directly impact your visibility and ranking potential.

Our Complete On-Page SEO Guide

To properly optimise your website, follow these steps on each of your pages.

If you have a large site, start with your most important 10–20 pages. Track how these optimisations impact your traffic and rankings, then refine your approach as needed.

1. Keep Each Page Focused on a Single Topic

When someone searches on Google, they expect to land on a page that directly answers their query. For example, you’re here because you want to learn more about on-page SEO – so that’s exactly what this page delivers.

The best-performing pages, both for readers and SEO, are those with a clear and singular focus.

By knowing precisely what a page should be about:

• You can create more relevant, in-depth content.
• It’s easier to optimise the page for search intent.
• You avoid competing with your own pages for the same keywords, which can weaken your SEO efforts (this is known as “splitting link juice”).

A Note on Keywords

Tracking specific keyword performance is getting trickier as search engines personalise results based on factors like location and search history.

Although keyword research is still important, our advice is to focus on the topics that matter to your audience. What would they search for to find the information you’re providing? That’s your starting point.

2. Prioritise High-Quality Content

Your website will always perform better in search rankings if it’s packed with useful, relevant, and unique content – written for real people first and search engines second.

Google’s algorithm is constantly evolving, but one thing remains unchanged: content quality matters.

Why High-Quality Content is Essential

While bounce rate and dwell time are important metrics for understanding user engagement, neither is directly recognised as a ranking factor by Google. However, they can indirectly influence rankings by signalling whether your content is relevant, engaging, and valuable to visitors.

If users land on your page and quickly leave, it may indicate that the content doesn’t meet their expectations. On the other hand, if they spend time reading and exploring other pages, this suggests stronger engagement and better content quality.

Tips for Creating High-Quality Content

1. Write Naturally
Keywords still play a role, but search engines now prioritise natural, conversational language. Writing in a way that feels authentic and engaging helps build trust and improves readability.

2. Check Your Spelling & Grammar
A website full of typos and errors looks unprofessional and may signal a lack of attention to detail. Poor grammar can also make it harder for search engines to understand your content.

3. Keep Your Site Fresh with Regular Blogging
Google rewards websites that frequently update with fresh, relevant content. A business blog helps you:

• Rank for a wider variety of keywords.
• Show your expertise and build credibility.
• Encourage backlinks and brand mentions.

4. Create In-Depth, Value-Packed Content
While short-form content has its place, longer, well-researched articles tend to rank higher. Studies suggest that the top-ranked pages often contain 2,000+ words because:

• They provide more depth and value to readers.
• They encourage visitors to spend more time on your site.
• They are more likely to attract backlinks from authoritative sources.

If you want better rankings and stronger engagement, focus on creating genuinely helpful, well-written content that keeps users on your site and encourages them to explore further.

3. Prioritise the User Experience (UX)

Google’s goal is to deliver the most relevant and useful search results while ensuring a great user experience. That means user experience (UX) should be a key focus when optimising your on-page SEO.

If your website is slow, hard to navigate, or difficult to read, visitors won’t stick around – and Google takes note.

When evaluating your web pages, ask yourself:

• Is the content genuinely useful? Does it answer the searcher’s query effectively?
• Is the page easy to navigate? Can visitors quickly find the information they need?
• Is the content well-structured and readable? Short paragraphs, clear headings, and bullet points improve scannability.
• Is the content well-researched and credible? Trustworthy sources and accurate information boost authority.
• Is the content visually appealing? Design, font choice, images, and whitespace all impact readability and engagement.
• Is the content accessible? Ensure mobile-friendliness, fast load speeds, and alt text for images.
• Does the page provide value? If visitors don’t find it useful, they’ll leave -hurting engagement and conversions.

UX and SEO: Why They Go Hand in Hand

A well-optimised page isn’t just about keywords—it’s about providing a frictionless experience that encourages users to stay, engage, and take action.

Elements that influence both UX and SEO include:

• Page speed – Slow pages drive users away. Optimise images, enable caching and use fast hosting.
• Mobile-friendliness – More searches happen on mobile than desktop, so responsive design is a must.
• Clear calls to action (CTAs) – Guide visitors to the next step with strong, clear messaging.
• Logical site structure – A well-organised site helps both users and search engines navigate easily.

If visitors have a positive experience, they’ll stay longer, engage more, and are more likely to convert – all signals that can help your rankings.

Focus on helping users first, and SEO success will follow.

4. Use a Focused and Descriptive Title Tag

Your title tag is one of the most important on-page SEO elements. It’s the clickable title that appears in search engine results pages (SERPs) and at the top of a browser tab when someone visits your page.

A well-optimised title tag not only helps search engines understand your page’s content but also influences click-through rates (CTR)—the percentage of users who click on your page after seeing it in search results.

Best Practices for Writing Title Tags

• Include your primary keyword early – Search engines give more weight to keywords near the beginning of the title.
• Make it compelling – Your title should grab attention and encourage clicks. Think of it as a mini-advert for your page.
• Avoid keyword stuffing – Keep it natural and user-friendly rather than forcing keywords in unnaturally.
• Keep it within 50-60 characters – This ensures your title displays fully in search results without being cut off.
• Write for humans, not just search engines – A clear, engaging title that aligns with search intent will outperform a robotic, keyword-stuffed one.

Example of an Optimised Title Tag:

Poor: “SEO Tips | SEO Best Practices | SEO Guide for Beginners” (Too repetitive and spammy)
Good: “SEO Best Practices: A Beginner’s Guide to Higher Rankings” (Clear, engaging, and keyword-rich)

Why Your Title Tag Matters

Your title sets the first impression of your page. A well-crafted title can increase clicks, improve rankings, and drive more traffic to your website.

By following these simple tips, you’ll create SEO-friendly title tags that attract both search engines and potential visitors.

5. Write Meta Descriptions That Stand Out in the SERPs

A meta description is the short snippet of text that appears beneath your page title in search engine results. While search engines no longer use meta descriptions as a direct ranking factor, they play a key role in influencing click-through rates (CTR) – helping users decide whether your page is the answer they’re looking for.

Here’s an example from one of our pages:

Here’s how to make your meta descriptions work harder for you:

• Make it compelling – Think of it as a mini ad for your page. Clearly describe what the page is about and give people a reason to click. A strong call to action (e.g., Discover how…, Find out why…, Learn more ) can make all the difference.
• Use keywords naturally – While Google doesn’t use meta descriptions as a ranking signal, it bolds matching search terms, making your snippet more eye-catching. Write naturally, and your keyword should appear without forcing it.
• Keep it concise – There’s no strict character limit, but aim for around 156 characters to avoid getting cut off with an ellipsis (…).
• Monitor & tweak – If your page is getting lots of impressions but a low CTR, your meta description might need a refresh. Experiment with different wording to see what drives more clicks.

An engaging, well-written meta description can be the difference between someone scrolling past your page or clicking through to your site – so make every word count.

6. Give Your Main Heading an <H1> Tag

Your main heading (H1) is one of the most important pieces of text on your page. Eye-tracking studies show that visitors instinctively look at the top left of a web page first – so your heading needs to instantly confirm they’re in the right place.

Beyond helping users, your H1 also signals to search engines what your page is about, making it an essential part of on-page SEO.

Here’s how to get it right:

• Use just ONE H1 tag per page – This keeps things clear for both users and search engines. Other headings (H2, H3, etc.) can be used to structure your content.
• Include your focus keyword naturally – Your H1 should reflect the central topic of your page. If you’re writing a page about “On-Page SEO,” that phrase should appear in your heading in a readable, non-spammy way.
• Check your CMS settings – Most website platforms (like WordPress) automatically apply an H1 tag to page titles, but some themes override this. Double-check that your main heading is actually using an <H1> tag.

Want to understand H1 heading tags in more detail? Read my guide: Your H1 Heading Matters More Than You Think (Especially in 2026)

How to Check Your <H1> Tag

Want to confirm if your page has a proper H1? Follow these steps:

1. Right-click on the page and select Inspect (or View Page Source).
2. Press Ctrl + F (Windows) or Cmd + F (Mac) to bring up the search function.
3. Type <h1> to find your main heading in the code.
4. If your title isn’t wrapped in <h1> and </h1>, it might need fixing.

Getting your H1 right is a quick SEO win – it improves user experience, helps rankings, and makes your content easier to navigate.

7. Break Up Your Content with Subheadings (Using Heading Tags)

Subheadings make your content easier to read and scan, helping visitors find the information they need quickly. Whether someone wants to read in-depth or skim for key points, well-structured headings improve the user experience.

Just like your main heading (H1), subheadings should be properly tagged with <h2>, <h3>, and so on. These tags help search engines understand the structure of your content and identify key topics.

Best Practices for Using Headings:

• Use H2, H3, and H4 tags in a clear hierarchy – Think of H2s as main section headings, H3s as sub-sections, and H4s for additional breakdowns within a section.
• Incorporate keywords naturally – Weaving in related terms and phrases reinforces your page’s relevance to search engines without keyword stuffing.
• Improve readability – Breaking up long text with headings makes your content less overwhelming and more inviting to read.

Example of a Good Heading Structure:

H1: The Complete Guide to On-Page SEO
H2: Why On-Page SEO Matters
H3: How Search Engines Understand Your Content
H2: Key On-Page SEO Elements
H3: Optimising Your Title Tags
H3: Writing Effective Meta Descriptions

Using headings effectively boosts SEO and user engagement – helping visitors and search engines navigate your content effortlessly.

8. Keep Your URLs Short, Simple, and Descriptive

A well-structured URL helps both users and search engines understand what your page is about at a glance. It should be clear, concise, and meaningful, reflecting your website’s structure.

Best Practices for SEO-Friendly URLs:

• Keep them simple and readable – A good URL should give users a clear idea of the page’s content.
  Example: yourdomain.co.uk/seo-tips
  Avoid: yourdomain.co.uk/index.php?id=2 (This tells users and search engines nothing!)
• Use hyphens (-), not underscores (_) – Search engines read hyphens as space separators but don’t recognise underscores the same way.
• Reflect website hierarchy – Your URL should show where a page fits into your site’s structure.
  Example:
  yourdomain.co.uk/services/seo (A service page about SEO)
  yourdomain.co.uk/blog/seo-tips (A blog post about SEO tips)
• Include keywords naturally – While it helps to have relevant keywords in your URL, keep it natural and avoid stuffing.

Why This Matters:

A clean, descriptive URL not only improves user experience but can also boost your click-through rate in search results. If users can instantly understand what your page is about just from the URL, they’re more likely to click through – and that’s a win for SEO

9. Place Your Focus Keyword in the First 100 Words

Each page on your website should have a clear focus, making it natural for your target keywords, phrases, and related terms to appear throughout the content. The key is to align your wording with the language your audience uses when searching for your products, services, or industry topics.

A simple yet effective tip is to include your main focus keyword within the first 100 words of your page’s body copy. This helps signal to both users and search engines that your content is highly relevant to their search query.

Optimising for Featured Snippets & AI-Powered Search

When crafting your introduction, think about how you can structure it for maximum visibility in search results:

• Use clear, concise language – Google’s featured snippets (the answer boxes at the top of search results) tend to pull from well-structured, easy-to-read content.
• Answer common questions directly – If your page provides a straightforward answer to a search query, it’s more likely to be chosen for featured snippets and AI-generated instant answers.
• Use lists, tables, or short paragraphs – These formats are favoured for AI-driven results and voice search responses.

Here’s an example of one of our featured snippets.

With the rise of AI-powered search tools, Google’s instant answers and AI-generated summaries are becoming more common. Structuring your content with clear, keyword-rich headings and well-organised information increases the chances of your website being featured in these results, driving more traffic to your site.

10. Make Your Copy Easy to Read

While long-form content tends to perform well in search rankings, big chunks of unbroken text can be overwhelming for readers – especially on a screen. Good formatting helps both users and search engines navigate your content with ease.

Here’s how to make your copy more accessible and engaging:

• Keep paragraphs short – Aim for 2-3 sentences per paragraph to improve readability.
• Use sub-headings – Clear, structured headings (like in this article!) help readers scan your content quickly and guide search engines through your page.
• Bullet points are your friend – They make key points easy to digest at a glance.
• Highlight important points – Use bold text or italics to draw attention to key ideas.
• Use high-quality images – Visuals break up text and reinforce your message, making your content more engaging.

By structuring your content with clarity and readability in mind, you’re creating a better user experience – which ultimately helps with SEO too

11. Use a Variety of (Optimised) Multimedia

Great web pages don’t rely on text alone. Images, videos, infographics, and diagrams can make your content more engaging and help explain complex ideas.

But here’s the thing – search engines can’t “see” images the way humans do, so proper optimisation is key.

Follow these best practices:

• Use descriptive file names – Rename images to include relevant keywords (e.g., SEO-tips-infographic.jpg instead of IMG12345.jpg).
• Add strong alt tags – Alt text helps search engines understand the image and improves accessibility for visually impaired users.
• Consider captions – Captions can provide extra context and improve engagement.

For more detailed guidance, check out our blog on optimising non-text elements to boost both SEO and accessibility

12. Apply Structured Data (Schema Markup) to Your Web Pages

Certain elements on a webpage – like reviews, product descriptions, recipes, and events – aren’t always easy for Google to interpret. That’s where structured data (Schema markup) comes in.

Schema markup is a way of providing extra context about your content so search engines can index it more accurately. It also helps enable rich snippets – those eye-catching extras in search results, like star ratings or event details.

A few things to note:

• Schema isn’t a direct ranking factor, but it can improve how search engines understand and display your content.
• There’s a correlation between structured data and better rankings, but experts debate how much of an impact it has.
• It can lead to quicker indexing since Google gets clearer signals about what your page is about.

If you want to stand out in SERPs and improve click-through rates, structured data is well worth implementing. Check out our guide on Schema markup to get started.

13. Use Outbound Links

Including outbound links to credible external sources can benefit your content in multiple ways:

• Boosts credibility – Citing reliable sources shows that your content is well-researched and backed by authoritative information.
• Enhances user experience – External links allow readers to explore a topic in more depth, making your content more valuable and informative.
• Can attract backlinks – Linking to reputable sites can sometimes put your content on their radar, increasing the chances of them linking back to you.

Best Practices for Outbound Links:

• Link to the source of any data, stats, or quotes you reference.
• Ensure links open in a new tab so users can check out external content without leaving your site.
• Only link to high-quality, authoritative sites to maintain trust and relevance.

Used wisely, outbound links strengthen your content while adding value for both users and search engines.

14. Use Internal Links to Connect Related Content

Internal linking is a powerful SEO strategy that enhances user experience, improves site structure, and helps search engines understand how your content is connected.

Why Internal Links Matter:

• Keeps visitors engaged – Linking to related content helps users explore different aspects of a topic, keeping them on your site longer.
• Boosts SEO – Internal links help search engines crawl and index your site more efficiently, improving rankings.
• Distributes link equity – Also known as “link juice,” internal links spread SEO value across your pages, strengthening overall site authority.

The Pillar & Cluster Model

Many websites use a Pillar & Cluster (or Hub & Spoke) model to organise content effectively:

• Pillar page (Hub): A long-form, comprehensive guide that covers a broad topic (like this On-Page SEO guide).
• Cluster pages (Spokes): More focused articles that dive deeper into subtopics, each targeting a different keyword.
• Smart linking: Each spoke links back to the pillar and vice versa, creating a strong internal network that boosts visibility.

Best Practices for Internal Links:

• Link naturally – Only add internal links when they genuinely help the reader.
• Use descriptive anchor text – Instead of “click here,” use text that clearly explains the linked content (e.g., “Check out our Ultimate Internal Linking Cheat Sheet“).
• Update your pillar content – Every time you add a new cluster post, update the pillar page to keep it fresh and relevant.

Done right, internal linking makes your site easier to navigate, strengthens your SEO, and keeps users coming back for more.

15. Avoid Duplicate Content (and Tell Google What Matters.)

Google rewards unique, valuable content – but sometimes, duplicate content is unavoidable, especially for product descriptions or service pages. If you have similar content across multiple pages, it’s crucial to handle it correctly to avoid SEO penalties.

How to Manage Duplicate Content Properly:

• Use Canonical Tags – A canonical tag (rel="canonical") tells search engines which version of a page is the main one to index. This prevents confusion and ensures the right page gets ranked.
• Consolidate Similar Pages – If multiple pages cover the same topic, consider merging them into one strong, authoritative page instead of competing with yourself.
• Use 301 Redirects – If a page is no longer needed, redirect it to a more relevant page so that users (and Google) land in the right place.
• Avoid Copy-Pasting Manufacturer Descriptions – If you run an eCommerce store, rewrite product descriptions to make them unique and valuable rather than using the same text as competitors.

For a deeper dive into duplicate content and how to handle it, check out Yoast’s guide to canonical tags.

By staying on top of duplicate content, you’ll keep Google happy and ensure your most important pages get the attention they deserve

16. Use Social Sharing Buttons

While social sharing buttons aren’t a direct ranking factor, they can significantly amplify your content’s reach. A study by BrightEdge found that websites with Tweet Buttons experienced nearly seven times more link mentions than those without.

BrightEdge However, it’s worth noting that this study was conducted over a decade ago, and user behaviour has evolved since then.

In recent years, the effectiveness of social sharing buttons has been a topic of discussion. Some argue that while these buttons can increase content reach, they may also impact website load times, potentially affecting user experience.

Mightybytes Additionally, the widespread use of browser extensions and built-in mobile sharing options has led some to question the necessity of on-page sharing buttons.

Despite these considerations, integrating social sharing buttons remains a common practice. They provide a convenient way for users to share content, potentially increasing visibility and driving traffic. Moreover, social shares can contribute to your site’s authority and influence, indirectly benefiting your SEO efforts.

Tips for Implementing Social Sharing Buttons:

• Strategic Placement: Position buttons where users are most likely to engage with them, such as at the beginning or end of articles.
• Minimalist Design: Opt for designs that complement your site’s aesthetics without causing distractions.
• Performance Considerations: Ensure that the buttons don’t significantly affect page load times. Lightweight plugins or custom-coded solutions can help maintain site speed.

By thoughtfully incorporating social sharing buttons, you can enhance user engagement and extend your content’s reach, supporting your overall SEO strategy.

17. Ensure Your Website is Mobile-Friendly

A mobile-friendly website isn’t just a bonus – it’s essential. With Google’s mobile-first indexing, search engines primarily use the mobile version of your site to determine rankings. If your website delivers a poor mobile experience, it could hurt your position in search results.

Here’s how to make sure your site is optimised for mobile:

• Test Your Mobile-Friendliness – Use Bing’s Mobile-Friendly Test to see how your site performs on mobile devices.
• Responsive Design – A responsive website automatically adjusts to different screen sizes, ensuring a seamless experience whether users are on a desktop, tablet, or phone.
• Mobile URLs vs. Responsive Design – While some sites use separate mobile URLs (e.g., m.yoursite.com) to serve mobile-specific content, a responsive design is generally preferred for SEO and user experience.
• Optimise for Touch – Buttons and links should be large enough to tap easily. No one likes pinching and zooming just to click a button.

A mobile-friendly website isn’t just good for SEO – it’s crucial for keeping visitors engaged and converting them into customers.

18. Check Your Page Load Speed

A slow-loading website frustrates users and can drive them away before they even see your content. Google knows this, which is why page speed is a ranking factor – faster sites provide a better user experience and tend to perform better in search results.

Here’s how to check and improve your page speed:

• Run a Speed Test – Use Google’s PageSpeed Insights to analyse your website’s performance. This tool provides a score for both mobile and desktop versions of your site and suggests improvements.
• Speed Matters – Slow-loading pages = higher bounce rates. Optimise images, enable caching, and minimise scripts to keep your site running smoothly.
• Reduce Unnecessary Code – Minify CSS, JavaScript, and HTML to remove unnecessary spaces, comments, and characters that slow things down.
• Enable Browser Caching – This allows returning visitors to load your site faster by storing elements of your page locally.
• Optimise Images – Large image files slow down loading times. Use compressed formats like WebP and lazy loading to improve performance.
• Check out our blog about low load speed fixes

If your website takes too long to load, visitors (and Google) won’t wait around. Make speed a priority to keep both users and search engines happy.

19. Fix Any Crawl Errors

Crawl errors can prevent search engines from properly accessing and indexing your web pages, which can hurt your SEO. If Google can’t crawl your site efficiently, your content might not appear in search results at all.

Here’s how to check and fix crawl errors:

• Use Google Search Console – Head to the Coverage Report in Google Search Console to identify any crawl issues on your site. Look for errors like “Crawled – Currently Not Indexed”, 404 errors, or server issues.
• Fix Broken Links and Redirects – If a page no longer exists, set up a 301 redirect to guide users (and search engines) to the next best page. This prevents visitors from landing on a 404 “Page Not Found” error.
• Check for Blocked Pages – Ensure that important pages aren’t accidentally blocked by your robots.txt file or meta noindex tags.
• Improve Site Structure – If your internal linking isn’t clear, some pages may not be crawled effectively. Ensure your navigation is intuitive, and use internal links to connect related content.

Crawl errors are like roadblocks for search engines – remove them, and you’ll help Google index your site more effectively. Want a deep dive? Check out our guide: How to Fix “Crawled – Currently Not Indexed” Pages in Google Search Console.

20. Check Your Robots.txt File

Your robots.txt file controls which parts of your website search engines can crawl and index. If important pages are mistakenly blocked, they won’t appear in search results – hurting your rankings and visibility.

Here’s how to check and fix your robots.txt file:

• View Your Robots.txt File – Type this into your browser: www.yourdomain.com/robots.txt
• Look for “Disallow” Entries – Any URLs listed under “Disallow” are blocked from search engines. Ask yourself: Should they be?
• Unblock Core Pages – Pages like your homepage, service pages, and key blog posts should never be disallowed. If they are, update your robots.txt file or remove the blocking directive.
• Use Google Search Console – use the Robots.txt report (found in settings) to understand if indexing and crawling issues are related to your robots.txt file and request a recrawl if needed. 

A properly optimised robots.txt file ensures search engines crawl and index your most valuable content.

SEO Success Starts On-Page

Google’s algorithm keeps evolving, but one thing remains constant: great content wins. By following these on-page SEO fundamentals, you’ll create a website that’s not only search-engine-friendly but also delivers a fantastic user experience.
