How to check on-page SEO
Updated June 20, 2026 · 8 min read
To check on-page SEO, work through the elements you control on the page itself: confirm the title tag is unique and descriptive, the meta description is written and relevant, there's a single clear H1 with a logical heading outline, the content fully answers the query, internal links connect related pages, images have descriptive alt text, and structured data is in place. View the page's source to confirm your key content is in the server-rendered HTML. Check these in order from highest impact (title, headings, content) down to the finer technical details, and fix the obvious gaps before moving on.
How do you check your title tag and meta description?
Your title tag is the strongest on-page signal and the headline most engines show in results, so check it first. Confirm the page has one title that is unique across your site, describes what the page is about, leads with the primary topic, and isn't so long it gets cut off in results.
Then check the meta description. It doesn't directly determine rankings, but it's the snippet that wins or loses the click. Make sure each important page has a written, relevant description rather than letting the engine guess one from the page text.
How do you check headings and content?
Headings give the page its outline. Confirm there is exactly one H1 that states the page's main topic, and that H2s and H3s break the content into a logical structure. Where it fits the query, phrasing H2s as the questions people ask helps both readers and AI answer engines.
For the content itself, check that it actually answers the query it targets, covers the topic with enough depth to be useful, uses relevant terms naturally, and isn't thin or duplicated from elsewhere on your site. A page that fully answers the search intent is the foundation everything else builds on.
What technical on-page elements should you check?
Once the title, headings, and content are solid, run through the supporting on-page elements:
- •Internal links: link to and from related pages with descriptive anchor text so crawlers and readers can navigate the topic.
- •Image alt text: describe images so they're accessible and give engines context.
- •URL: keep it short, readable, and reflective of the page's topic.
- •Canonical tag: confirm the page points to itself (or the correct primary version) to avoid duplicate-content confusion.
- •Structured data: add schema that matches the visible content — FAQPage for Q&A, Article, Product, or Organization where they apply.
- •Server-rendered HTML: view the page source and confirm your key text is present, not loaded only after JavaScript runs.
- •Mobile readiness: check the page is legible and tappable on a small screen.
How do you check on-page SEO faster?
Going element by element is thorough but slow, and it's easy to miss something. A page-level SEO checker runs the whole checklist at once and tells you which items pass and which need work.
Revenue Grader's free page SEO checker grades a page across these on-page signals and returns a prioritized fix list, so you work the highest-impact issues first instead of guessing the order. It also grades AI-search readiness alongside classic on-page SEO, which manual checks often skip.

Frequently asked questions
- What is on-page SEO?
- On-page SEO is everything you control on the page itself to help it rank and get understood: the title tag, meta description, headings, content, internal links, images, URL, canonical tag, and structured data. It's distinct from off-page SEO (such as backlinks) and from site-wide technical SEO, though they all work together.
- How do I check my title tag?
- Open the page and view its source, or use a page SEO checker, and confirm the title is present, unique across your site, descriptive of the page's topic, leads with the primary term, and short enough not to be truncated in search results. The title is the single highest-impact on-page element, so it's worth checking first.
- How often should I check on-page SEO?
- Check on-page SEO whenever you publish or substantially edit a page, and re-check important pages periodically — content, intent, and best practices drift over time. Pages that drive revenue or rank for valuable queries are worth checking most often.
