We all know the important role SEO plays in hiking your website ranking up in search engines like Google. It helps drive more traffic and opens the door to new potential customers. But SEO is a broad term for many different facets that all play a key part in getting you seen by your target audience. In fact, SEO covers several interconnected areas, including on-page, off-page and technical SEO. In this post, we’ll focus solely on on-page SEO.
Let’s break it down…
TL;DR
On-page SEO is the process of improving the content and elements on individual pages of your website so they’re easier for people and search engines to understand.
Good on-page SEO starts with creating genuinely useful content that matches what your audience is searching for. From there, elements such as page titles, headings, internal links, meta descriptions, images and mobile usability can all help make the page clearer, easier to navigate and more relevant to the people you want to reach.
To improve your on-page SEO:
- Create useful content that answers the searcher’s question or solves their problem.
- Understand the search terms your audience uses, but write naturally rather than forcing keywords into the page.
- Use descriptive page titles and clear, logically structured headings.
- Write useful meta descriptions that encourage the right people to visit your page.
- Add relevant internal links that help people discover related content.
- Use descriptive image filenames and meaningful alt text where images need explaining.
- Make sure the page works properly and contains the same important information on mobile.
- Review and update existing pages when the information, search behaviour or needs of your audience change.
On-page SEO won’t guarantee you the top spot in Google, but it gives search engines a much clearer understanding of your content while creating a better experience for the people who find it.
What is on-page SEO?
First, let’s take a look at on-page SEO and how it will help you improve your site rankings.
When we talk about on-page SEO, what we’re referring to is the aspects you can control on your website in order to make it more favourable for search engines. Imagine you went into a shop and it was a complete mess. You wouldn’t stick around for long, would you? So, a common analogy is to think of on-page SEO as tidying your “shop” (website), getting it in tip-top shape for customers.
What does on-page SEO involve?
Essentially, on-page SEO covers content quality, keywords, title tags and meta descriptions, headings and subheadings, internal links, image optimisation, and ensuring your site is mobile-friendly.
Together, each of these elements are incredibly important for determining whether your site gets seen by the people you want it to. So, let’s have a think about them in a bit more detail…
Content quality and search intent
Good on-page SEO starts with useful content. Search engines are trying to understand whether a page genuinely helps someone find the information, product or service they were looking for, so simply repeating a target keyword throughout the copy isn’t enough.
That’s where search intent comes in. Search intent is the reason behind a search: what does the person actually want to know or do?
Someone searching for “what is on-page SEO?” is probably looking for an explanation and practical advice. Someone searching for “SEO agency near me”, on the other hand, is much more likely to be comparing providers and considering buying a service. Both searches relate to SEO, but they need very different types of pages.
Before creating or optimising a page, look beyond the keyword itself and consider the question or problem behind it. What information would genuinely help that person? What follow-up questions are they likely to have? Are they looking to learn, compare options, solve a problem or take action?
Strong content should answer those needs clearly and thoroughly, while bringing something useful of its own. That might be first-hand experience, original examples, expert insight, practical guidance or a clearer explanation than someone can find elsewhere.
Keywords still matter because they help you understand the language your audience uses, but they should guide the content rather than dominate it. Write naturally, use relevant terms where they make sense and concentrate on creating a page that deserves to satisfy the search in the first place.
It’s also worth reviewing existing content over time. Search behaviour changes, information becomes outdated and your own experience grows. Updating a page when you have something genuinely useful to add can keep it accurate, relevant and valuable to the people finding it.
Keywords
If you’re not entirely sure what keywords are, we have a dictionary entry that explains them in more detail but, essentially, they are the terms that people type into Google when they’re looking for information. Tools such as Google Keyword Planner will help you find the most relevant keywords for your business.
Title tags
A title tag is the HTML title assigned to a webpage. It helps search engines understand what the page is about and is one of the main signals Google can use when creating the clickable title shown in search results.
That doesn’t mean Google will always display your title tag exactly as you wrote it. Search engines can sometimes generate a different title using other prominent text on the page, such as the main heading, if they think that better represents the content.
A good title tag should therefore describe the page clearly and accurately while giving someone a reason to click. Include the main topic or search phrase where it fits naturally, but avoid forcing keywords into the title or repeating them unnecessarily.
For example, a title such as “On-Page SEO: What It Is and Why It Matters | KAYBE” immediately tells both the reader and search engine what they can expect from the page.
Keep each important page title distinctive too. If several pages use vague titles such as “Services”, “Learn More” or “Welcome”, it becomes harder for both people and search engines to understand how those pages differ.
Ultimately, the title should match the content that follows. A clever or attention-grabbing title might earn a click, but if the page doesn’t deliver what it promises, it won’t create a good search experience.
Headings and subheadings
As I mentioned above, making sure the content on your site is as relevant as possible is vital, but so is making sure that content is properly structured, as this makes it easier for readers and search engines to break down. That’s where using headings and subheadings – H1, H2, H3, and so on – come in. Your main title should be an H1, with subsequent headings in descending order of importance.
Internal links
You’ve likely heard that links are super important, and that is very true. Linking out to other pages on your site helps your site visitors find content that’s relevant to them and helps keep them on your site for longer. Adding relevant internal links also helps search engines crawl your site, which is important for ensuring your site gets found. Google recommends logical internal linking with concise, relevant anchor text.
Image optimisation
Once you’ve chosen images that match the theme of your content and the overall look and feel of your site, it’s really important to optimise those images. This includes making sure they’re the right size. Give images short, descriptive filenames where practical and write useful alt text that explains the image when that information is relevant. Don’t force keywords into filenames or alt text simply for SEO. Why does this matter? Well, it helps get your images appearing in search results, too. Making sure they’re the right size is also important for improving page load speed.
Mobile usability
Mobile usability is an important part of on-page SEO because Google uses the mobile version of a page for indexing and ranking. That means the content and experience available on mobile should be just as complete and useful as the desktop version.
A mobile-friendly page should be easy to read and navigate without excessive zooming, horizontal scrolling or awkwardly placed buttons. Text should be legible, menus should work properly and calls to action should be easy to use on a smaller screen.
It’s also important that key content doesn’t disappear on mobile. Your headings, main copy, internal links, images and other important information should remain available so that users and search engines are seeing the same essential page.
Performance matters too. Large images, heavy scripts and unnecessary page elements can make a mobile page slow and frustrating to use, so keeping pages lightweight and responsive can improve the overall experience.
The aim isn’t simply to make a desktop page fit onto a smaller screen. It’s to make sure someone using a mobile device can find, understand and act on the information just as easily as someone visiting from a desktop computer.
Why it pays to get on-page SEO right
On-page is essential for improving your SEO strategy and plays a major role in getting your site out into the world and found by the right people. It ensures your website is optimised for search engines and provides a great user experience.
On-page SEO FAQs
What is on-page SEO?
On-page SEO is the work you do on individual pages of your website to make their content easier for people and search engines to understand. It includes the quality and relevance of your content, page titles, headings, internal links, images, meta descriptions and the overall experience someone has when visiting the page.
What is the difference between on-page and off-page SEO?
On-page SEO focuses on elements you can improve on your own website, such as content, headings and internal links. Off-page SEO relates to signals and activity outside your website, such as other websites linking to your content.
You may also hear people talk about technical SEO, which focuses more closely on the technical foundations that allow search engines to crawl, render and index a website effectively.
What are the most important elements of on-page SEO?
There isn’t one on-page SEO element that will make a page rank on its own. Strong pages bring several things together, including useful content, a clear understanding of search intent, descriptive page titles, logical headings, relevant internal links, properly optimised images and a good experience across different devices.
The priority should always be helping the person who has landed on the page find the information they were looking for.
Do keywords still matter for on-page SEO?
Yes, but keyword optimisation isn’t about repeating the same phrase as many times as possible. Keywords can help you understand how your audience searches and the language they use when looking for a particular product, service or piece of information.
Use that insight to shape your content, titles and headings naturally. The page still needs to properly answer the searcher’s question rather than simply contain the right words.
Does on-page SEO help with AI search?
Good on-page SEO can also make your content easier for AI-powered search experiences to discover and understand. You don’t need a completely separate optimisation strategy for AI search; clear structure, useful original content, descriptive headings, crawlable pages and established SEO best practices remain important.
The bigger opportunity is to create content that brings genuine expertise, experience or insight rather than simply repeating information that already exists elsewhere.
While the idea of SEO might seem complicated or overwhelming, it pays to get advice from an expert. An SEO agency will help you take the right steps to moving up the search engine rankings and get your content, products and services seen.
On-page SEO is only part of the picture
Getting your on-page SEO right gives search engines a much clearer understanding of your website and helps visitors find the information they need. But the way people search is changing, with AI-powered search experiences increasingly influencing how businesses get discovered online.
