On-Page SEO Checklist: 15 Checks Before You Publish
Short answer: before publishing, check that the page matches what people searching for it want, answers their question early and better than other pages, and has a unique descriptive title, a clear main heading, a short unique meta description, a readable URL, alt text on images, and descriptive links to and from related pages. Then make sure it’s indexable. Skip what Google says it ignores: meta keywords, keyword density, word-count targets and heading counts.
Content
- Match search intent. Search your main query and look at what ranks: guides, product pages, tools or lists. Make the same kind of page, but better.
- Answer the question early. Put a direct answer in the first paragraph, then the detail. People and AI answers both pick up clear, self-contained passages.
- Make it original and current. Google’s starter guide asks for content that is helpful, reliable, unique and up to date. Add your own examples, data or steps that other pages lack.
- Use the words people search for. Google suggests thinking about the words a user might search for. Use them naturally in the title, main heading and text; never stuff them.
- Make it easy to read. Short paragraphs, plain words, lists for steps, and tables for comparisons.
Title, description and headings
- Unique, descriptive title. Google: a good title is unique to the page, clear and concise, and describes the content. There is no length limit, but long titles get cut off in results, so put the important words first.
- Unique meta description. A short summary written for this page only. Google may show different text from the page when it fits the search better.
- One clear main heading (H1). Say what the page is about. Use subheadings to break up the content; Google says there’s no ideal number or order of headings for Search, so structure for readers.
URL, images and media
- Readable URL. Use words that help people, like /blog/on-page-seo-checklist, and group related pages in folders. Keywords in the URL have hardly any effect on ranking, so don’t rename old URLs just for that.
- Image alt text. A short description of what the image shows and how it relates to the content. Place images near the text they support.
- Video on its own page. If a video matters, embed it on a page about that video, near relevant text.
Links and technical basics
- Descriptive internal links. Link to and from related pages with anchor text that says what the target page is about, not “click here”.
- Link out where it helps. Cite sources and useful resources. Mark paid links rel=“sponsored”.
- Indexable and canonical. The page returns 200, has no noindex, and has a self-referencing canonical (or one pointing to the main version).
- Structured data where it fits. Article, Product, Recipe and other types can make results richer. It must match what’s visible on the page.
What not to spend time on
Google’s SEO Starter Guide lists things that don’t help the way many checklists claim:
- Meta keywords: Google Search doesn’t use them.
- Keyword density: stuffing keywords is against Google’s spam policies.
- Word count: length alone doesn’t matter for ranking.
- Heading counts and order: no magic number; order matters for accessibility, not for Search.
- Keywords in the domain or URL: hardly any effect.
- E-E-A-T as a score: Google says it isn’t a ranking factor; it’s a way to think about trustworthy content.
After you publish
- Make sure the new URL is in your XML sitemap, and that the sitemap lists only live, indexable pages. The free sitemap checker tests 30 sitemap URLs for errors, redirects, noindex and canonical problems.
- Add links to the new page from 2–3 related pages so Google and readers can find it.
- Check it with URL Inspection in Search Console a few days later.
- After 4–8 weeks, look at the queries it gets impressions for in the Performance report, and adjust the title and content to match them.

Frequently asked questions
What are the most important on-page SEO elements?
Content that answers the searcher’s question better than other pages, a unique and descriptive title, a clear main heading, helpful internal links with descriptive anchor text, and images with alt text. Google’s starter guide treats the content itself as the thing that matters most.
Does keyword density matter?
No. Google says keyword stuffing is against its spam policies. Use the words people search for where they fit naturally, especially in the title and main heading.
How long should a page be for SEO?
Google says the length of the content alone doesn’t matter for ranking. Write as much as the topic needs to be useful, and no more.
Do meta keywords help?
No. Google Search doesn’t use the keywords meta tag.
What is the 80/20 rule in SEO?
An informal idea that most results come from a small share of the work. For on-page SEO, the high-value 20% is usually matching search intent, the title, and the quality of the main content.
