Why does a page with good content sit on page two while a thinner page outranks it?
Often it’s not the content itself.
It’s how the content is packaged: the keywords it targets, the title, the headings, the first paragraph and the links around it.
That’s what on-page AI SEO covers. It’s everything you control on the page itself, as opposed to off-page AI SEO like backlinks and mentions.
This on page AI SEO checklist runs in the order I use it. Each check tells you what to look at, how to verify it and how to fix it.
Run it on your 10 most important pages first. Those pages likely bring most of your leads, and I’d rather see 10 pages of content done well than 100 done halfway.
Check 1: pick one primary keyword for each page you want to rank.
Each page should target one main search, plus close variants.
If two of your pages target the same keywords, they compete with each other, and neither content page gets the ranking it deserves.
Verify it by searching your keyword on Google. If the top results are guides and your page is a product page, you’re fighting the search intent, and that content won’t rank.
Check 2: write your title tag around that primary keyword.
Put your primary keyword near the start of the title, then a reason to click on your content. Keep it within about 60 characters so it doesn’t get cut off on a phone.
Google says it uses your title element around 87% of the time. If Google rewrites yours, the title likely didn’t describe the page content well.
Check 3: write a meta description that makes people want to click.
Your meta description doesn’t change your rankings directly. But it can change how many people click.
Google says it mainly uses page content to create the snippet, and uses your meta description when it describes the page better. So write one clear sentence about what the reader gets.
Check 4: keep your URL short, readable and close to the keyword.
Use a short slug with your keywords, like /water-purifier-repair/. Avoid dates, IDs and long strings of words.
Don’t change an old URL that already ranks just to add keywords. If you must, use a 301 redirect.
Check 5: use one H1 and clear headings that outline your content.
Your H1 should say what the page is about, with the primary keyword in it. Then use H2s for the main sections and H3s inside them.
Read only your headings, top to bottom.
Do they tell the whole story of your content? If not, I’d rewrite them before touching the body text.
Check 6: answer the main question in your first 100 words.
Your reader wants the answer fast, and so do Google and AI tools reading your content. Put the direct answer in your first paragraph, then explain.
This first block of content is the part most likely to be quoted in AI Overviews and ChatGPT, because that content stands on its own.
Check 7: make your content more useful than the pages that rank today.
Open the top five results for your keyword.
What do they cover that your content doesn’t? And what do you know from your own business that their content doesn’t?
Google’s guidance on helpful content asks whether your page adds original information, research or analysis. Length alone isn’t the goal. Useful content that answers the next question is.
Check 8: use your keywords naturally, and cover the variants people search for.
Use your primary keyword in the title, H1, first paragraph and a few headings. Then use the variants and related keywords people search for, like the questions in Google’s People Also Ask box.
Don’t repeat keywords to hit a number.
Google’s spam policies call that keyword stuffing, and it might hurt your ranking instead of helping it.
Check 9: add internal links to the page with descriptive anchor text.
Link from this page to related content, and link to it from your strongest pages. Use anchor text that says what the target page is about, not “click here”.
Your crawler or Search Console’s Links report shows how many internal links each page gets. A common mistake I see is a service page with zero internal links from the blog content that mentions it.
Check 10: optimize your images for speed, context and accessibility.
Give each image descriptive alt text, a sensible file name and a compressed WebP or AVIF file, because heavy images are also a technical AI SEO problem. Google also uses alt text as the anchor text for linked images.
Check 11: add schema that matches the content on the page.
Use Article, Product, LocalBusiness, BreadcrumbList or Organization schema where it fits, and test it in Google’s Rich Results Test.
One change trips up a lot of people. Since August 2023, Google shows FAQ rich results only for well-known government and health websites, so don’t add FAQ schema expecting extra space in results.
Check 12: show who wrote the content and why readers can trust it.
Add an author name and bio, the date you last updated the content, and links to the sources behind your content. This helps readers trust you, and it gives Google and AI tools clear signals about your experience.
Check 13: make your content easy for AI search tools to quote.
Write short, factual passages of content that answer one question each.
For example, “A water purifier filter usually needs changing every six to twelve months” is easier to quote than a paragraph about your brand story. Name your sources in the sentence, and keep your brand details the same as on your other pages and your Google Business Profile, which also supports your local AI SEO.
Google says there are no special optimizations needed for AI Overviews. Good on-page AI SEO content is the work.
A worked example of this on page AI SEO checklist.
Let’s say you sell water purifiers in Chennai, and your “RO purifier service” page ranks around position 14.
Check 1 shows that your blog post on RO service targets the same keywords, so the two pages split the clicks. You merge the post into the service page and redirect it.
Check 2 shows a title that starts with your brand name, so you move the keywords to the front. Check 6 shows your first paragraph is about company history, so you replace it with the price band, the visit time and the areas you cover.
Check 7 shows the top results answer “how often should an RO filter be changed”, and your content doesn’t. You add that answer, with your service schedule, as new content near the top.
Check 13 then shows your area names don’t match your Google Business Profile, which hurts your local AI SEO, so you align them.
In a scenario like this, you’d expect the page to climb over the next few months, because it now matches the search better than before. That’s a likely outcome, not a guarantee.
