Key takeaways
- An on-page SEO checklist for 2026, updated for AI search: lead with the answer, shape headings as questions, and get titles, links and schema right.
- Lead with the answer. Open every page and section with a direct, self-contained response a reader or an AI engine can lift in one go.
- Shape headings like the questions people ask, and keep each passage able to stand on its own so one section answers one thing fully.
- Keep the fundamentals tight: a unique title, a useful meta description, descriptive anchor text, and internal links to related pages.
- Make the page machine-readable: schema that matches what is on screen, real text for every key fact, and descriptive alt text on images.
On-page SEO in 2026 is the work of making a single page easy for both a person and a machine to read, trust and quote. The old version optimised a page to rank for a keyword. The current version does that and makes sure a specific answer on the page can be retrieved, verified and attributed by an AI engine, so you are found in Google and in AI answers at once.
What follows is a pre-publish checklist you can run on every page before it goes live. Work through it top to bottom and you cover the elements that still move rankings, plus the ones that decide whether you appear in an AI Overview or an assistant’s reply.
What on-page SEO means in 2026
On-page SEO is everything on the page itself that helps search engines and AI assistants understand and serve your content: the words, the structure, the titles and metadata, the links to other pages, the schema, and the media. It sits on top of a technically sound site. If crawlers cannot reach or render the page, none of this lands, which is why on-page work follows a clean technical SEO audit rather than replacing it.
What has changed is who is reading. Google now answers a growing share of queries with an AI Overview, and more people ask an assistant instead of a search box. Google’s own guidance is plain about eligibility: to show up as a supporting link in AI Overviews or AI Mode, a page must be “indexed and eligible to be shown in Google Search with a snippet”, with no special markup or AI-only files required (Google Search Central). So strong on-page SEO is the price of entry for AI visibility too. For the off-site and entity side of that job, see our guide to answer engine optimisation.
The 2026 on-page checklist at a glance
Here is the full checklist in one place: the element, and what good looks like in 2026. Use it as a quick pre-publish pass, then read the detail below for the parts that need judgement.
| Element | What good looks like in 2026 |
|---|---|
| Search intent | One clear job per page, matched to a real question or task. |
| Answer-first opening | First one or two sentences answer the main question outright, in plain text. |
| Headings | One H1 that states the topic; H2s and H3s shaped like the questions people ask. |
| Passage structure | Short, self-contained sections, one idea each, that make sense lifted out on their own. |
| Title element | Unique, descriptive, topic first, brand after a divider, concise enough to survive truncation. |
| Meta description | A specific, honest summary written for the click; around 150 characters so it is rarely cut. |
| URL | Short, readable, lowercase, words separated by hyphens, no tracking clutter. |
| Internal links | Contextual links to related pages, so each important page is linked from at least one other. |
| Anchor text | Descriptive and concise, naming the destination; never “click here” or “read more”. |
| Key facts as text | Prices, locations, specs and claims written as real text, not locked inside images. |
| Images | Compressed, correctly sized, with descriptive filenames and useful alt text. |
| Structured data | JSON-LD that matches what is visible on the page, validated and kept accurate. |
| Author and entity | A named author, visible dates and one consistent business name, so the source is identifiable. |
| Readability | Plain language, good contrast, logical heading order, works on a phone. |
Lead with the answer, then expand
Open every page, and every section, with a direct answer the reader gets in one or two sentences, then add the depth underneath. This single habit does the most for AI visibility, because retrieval happens at the level of a passage, not a whole page.
An AI engine, like an impatient reader, wants the answer without wading through preamble. If a page makes someone read four paragraphs before the point, a model will lift a cleaner sentence from somewhere else. Google’s advice to keep important content available in textual form is the same instinct: say the thing plainly, in words, near the top.
Shape headings like the questions people ask
Write headings that mirror how people actually phrase a question, because those headings are what a machine matches to a query. “How much does an on-page audit cost?” works harder than “Pricing”, because it matches the words a real person types or speaks. Use the heading to pose the question, then answer it in the first line beneath.
Keep each passage able to stand alone
Each section should answer one thing completely, so it survives being pulled out of context. A tidy, self-contained chunk travels into an answer far better than a point spread across three rambling paragraphs. This is why a proper FAQ block earns its place: each question-and-answer pair is a ready-made, quotable unit.
Nail the fundamentals: titles, meta descriptions and headings
The classic on-page signals still matter, so get the title, the meta description and the heading structure right on every page. These are the first things both Google and an AI snippet read.
Titles
Write one unique, descriptive title per page, lead with the topic, and keep it concise enough to survive truncation. Google builds the clickable title link mostly from your title element, and rewrites it when it is vague, keyword-stuffed or repeated across pages. Put the site name at the start or end, after a divider such as a pipe or hyphen (Google Search Central). Around 50 to 60 characters is a safe working length, since titles are trimmed to fit the device.
Meta descriptions
Write a specific, honest summary that earns the click, rather than stuffing keywords. Google often uses your meta description for the snippet when it describes the page better than text pulled from the body, though it may rewrite it to match a given query (Google Search Central). There is no hard character limit, but around 150 characters tends to display in full. One description per page, matched to the content on it.
Headings and structure
Use one H1 for the main topic and nested H2s and H3s to break the page into logical, scannable sections. Headings give both readers and machines a map of the page. Keep the order logical, so do not jump from an H2 to an H4 for the sake of styling, and let the words carry the meaning rather than relying on size alone.
Connect the page: internal links and anchor text
Link each page to the related pages around it, using anchor text that describes where the link goes. Internal links help Google find content, pass authority between pages, and signal which pages matter most.
Google’s guidance here is practical: a link is only crawlable as an <a> element with an href, good anchor text is “descriptive, reasonably concise, and relevant to the page”, and every page you care about should have a link from at least one other page (Google Search Central). Skip “click here” and “read more”, which tell a machine nothing about the destination.
In practice: link new posts from established ones, point to your priority pages from relevant context, and keep important pages within a few clicks of the homepage. This is core to how we structure SEO and growth work, because a well-linked page is easier to rank and easier to cite.
Label the page: schema, entities and authorship
Add structured data that matches what is on the page, and make the source behind the page easy to identify. Schema removes the guesswork for a machine about what each part of your content means.
Use JSON-LD, which Google recommends as the easiest format to maintain, and only mark up information that is actually visible to the user, because marking up hidden content breaks the rules (Google Search Central). Match the type to the page: Organization or LocalBusiness for your core details, Article with an author and date for editorial, FAQPage where genuine questions and answers appear, Product and Review for shops. Validate it, then keep it accurate when the page changes. We go deeper in schema and structured data for AI search.
Alongside the code, state the plain facts a reader and a model both check: a named author, a visible published or updated date, and one consistent business name. These are part of showing the content was made by people with a reason to be trusted, which is the heart of Google’s helpful content guidance.
Media and accessibility: images, alt text and readability
Give every informative image a descriptive filename and useful alt text, and keep the whole page fast, legible and usable on a phone. Media is part of on-page SEO, not decoration bolted on at the end.
Google calls alt text “the most important attribute” for understanding an image, so describe what the image shows in context rather than stuffing keywords, and name the file something meaningful such as team-photo-leicester.jpg rather than IMG_0423.jpg (Google Search Central). Place images next to the text they illustrate, serve them compressed and correctly sized, and use real <img> elements so they can be found.
Accessibility and readability pull in the same direction as retrieval. Plain language, sensible contrast, a logical heading order and genuine text, rather than words baked into graphics, make a page easier for a screen reader, a search engine and an AI model alike. If a fact exists only inside an image, assume the machine cannot read it.
Your pre-publish checklist, and where to start
Before any page goes live, run it against the table above: one clear job, an answer-first opening, question-shaped headings, a tight title and description, descriptive links, matching schema, and real text for every key fact. Do that consistently and you cover both the ranking signals and the retrieval signals in one pass.
None of this is exotic, and most of it costs nothing to fix. The work is in doing it on every page, every time, rather than once on the homepage and never again. That discipline is what quietly separates the sites that get found from the ones that do not.
