On-Page SEO Checklist: 19 Checks in Priority Order, With Results From 89 Real Articles

An on-page SEO checklist covers what you control on the page itself: intent match, title, headings, content depth, internal links, images, schema and speed. Work it in priority order. Intent and indexability decide whether a page can compete at all, so they come before schema markup or image compression.

Most checklists treat a title fix and a schema update as equal work, and they do not show what happens when you pass. So on 6 November 2026 we ran the measurable checks on all 89 live Anobee articles. Nearly everything passed, one check did not, and this page shows the limit of a passing score.

What happened when we ran the on-page SEO checklist on 89 articles

We read the live HTML of every article in Anobee's sitemap. Eight checks can be measured that way.

Internal links were the one real gap. Eleven articles had no link from another article's body, and 35 had two or fewer. Hub pages and navigation can still link to them, but those were not counted here.

This guide passes all eight rows, including 11 links from other articles, and it still averaged position 84.1 in Search Console from June to November 2026, for 857 impressions. For "on page seo checklist" it averaged position 88.6.

So an on-page SEO checklist is a floor, not a ranking plan. Passing removes obvious faults. Competition and links from other sites likely decide the rest. We have not measured those for this page, so treat that as our reading, not a finding.

The on-page SEO checklist, in priority order

Work tier one to completion before you start tier two. The order is our judgement about leverage, not a Google hierarchy.

Tier one: checks that decide eligibility

1. Search intent match

Search intent is the reason behind a query. Search your keyword and look at the top five results. If they are all comparison posts and your page is a product page, the format is wrong, and no title rewrite fixes that. Our search intent guide shows how to read a results page.

2. Indexability

Confirm the page returns 200, is not blocked in robots.txt, has no noindex, and has a canonical pointing to itself. An X-Robots-Tag header never appears in the HTML, so check the response headers too. URL Inspection in Search Console gives the authoritative answer.

3. Honest title tag

Keep the main phrase near the front, stay close to 60 characters, and describe what the page delivers. A 2022 Zyppy study of 80,959 titles across 2,370 sites found Google rewrote 61.6% of them [5]. A rewrite is not a penalty, but it does suggest that something else described the page better.

4. H1 and the first 100 words

Use one H1 that matches the title's meaning. Then answer the query in the opening paragraph, without warming up.

5. One inbound internal link

Google says it "primarily finds pages through links from other pages it already crawled" [1]. This is the check Anobee's audit flagged most. Our internal linking strategy covers how to audit a whole site.

Tier two: checks that build the case

6. Content depth

Depth is not word count. Open the top three pages, list every H2 they have that you do not, and add the gaps that genuinely belong. A page that nearly ranks is usually missing a few real subtopics, not thousands of words.

7. Heading structure

Do not skip levels or use headings for styling. Write them as descriptions: "How to find orphan pages" beats "Orphans".

8. Entity coverage

A topic has related concepts that belong together. Covering them matters more than repeating a phrase. Keyword density is a legacy metric, and "aim for 1 to 2%" has no basis in Google's guidance. Entity optimization goes further.

9. Internal links out

Link to pages that help readers continue. Google says good anchor text is "descriptive, reasonably concise, and relevant", and that there is no magical ideal number of links [4].

10. Image handling

Use descriptive file names, alt text that describes the image, modern formats and fixed dimensions. Lazy-load everything except the image likely to be the largest on first paint. The image optimization guide has real file size tests.

11. External sources

Link to the primary source for any claim a reader might doubt. This is a standard for honest writing more than a ranking lever, and it catches claims you cannot support.

12. Meta description

It does not rank the page. It influences the click. Answer "why this result?" in under about 160 characters.

13. URL structure

Keep URLs short, readable, lowercase and stable. Avoid dates and numbers you will want to change, because every later change means a redirect.

14. Schema markup

Schema makes a page eligible for rich results where it qualifies. It does not lift rankings directly. Use types Google supports, validate them, and mark up only visible content. See structured data for bloggers.

Tier three: checks that compound

15. Core Web Vitals

Google says "There is no single signal", and also that "Core Web Vitals are used by our ranking systems" [2]. It adds that Search "always seeks to show the most relevant content, even if the page experience is sub-par" [2]. So speed matters, but relevance wins.

In May 2026 we measured mobile LCP on this site at 4.1 seconds, and hero image preloading on the five busiest posts brought those to 2.1 seconds. A November 2026 lab test of one article showed 3.2 seconds, so check your own pages rather than trusting an old number. Largest Contentful Paint is usually an image or render problem, so look there first.

16. Mobile rendering

Google indexes the mobile version. Check that collapsed sections exist in the HTML, tables stay readable, and nothing important needs a tap to load.

17. Keyword cannibalization

Filter Search Console by the query, open the Pages tab, and look for a second URL. The usual fix is to pick the stronger page, merge the useful parts of the weaker one, and redirect.

18. Content decay

Pages decline quietly. Compare important pages with the same period last year each quarter. A content audit formalizes this.

19. Passage clarity

Google can rank a specific passage, but it still indexes the page as a whole. Write sections that make sense on their own, and define terms right after the heading that introduces them.

What to do when a page ranks but not well enough

Running the whole on-page SEO checklist again is usually wasted effort for a page in positions 8 to 20, because most of it already passes. Use this shorter sequence:

1. Re-check intent against the top five.
2. Look for a second URL of yours on the query.
3. Close real coverage gaps.
4. Add internal links from relevant pages.
5. Rewrite the title and description to earn the click.
6. Add schema where it qualifies.
7. Request a recrawl once, after several real changes.

Nobody can honestly give you a timeline. Record the date of each change, and compare over a window long enough to survive normal swings.

On-page SEO and AI features

Google says "You don't need to create new machine readable files, AI text files, markup, or Markdown to appear in Google Search" [3]. It also says you can ignore tactics like chunking content [3].

Clear writing, explicit definitions and sources a reader can check serve people and AI features alike. For more, see how AI Overviews work and SEO vs GEO vs AEO.

What E-E-A-T is, and what it is not

E-E-A-T stands for experience, expertise, authoritativeness and trustworthiness. Google's SEO Starter Guide lists thinking it is a ranking factor as a mistake [1]. There is no score to raise. Treat it as a content standard: a named author, visible dates, linked sources, and specifics in place of generalities.

Common mistakes

• Working top to bottom. Schema on a page with an intent mismatch is wasted effort.
• Stopping at a clean audit. Anobee's articles passed almost everything, and this one still sits near position 84.
• Ignoring inbound links. Eleven of our own articles had none from another article.
• Optimizing for density. Repetition is not coverage.
• Treating a title rewrite as a penalty. It is feedback.
• Marking up hidden content. Structured data must match what readers see.
• Publishing and walking away. Decay is the default.

Start with intent and indexability. Earn the title. Then check who links to the page, because that was the one on-page SEO checklist item our own site failed. Markup and milliseconds can wait.
