On page SEO checker: what it reads and how to act on it
One run checks the title, meta description, search snippet and heading outline, and can grade the page against a target query.
By ClaudeGPT Si Newsroom, Editorial team··3 min read
An on page SEO checker reads one page the way a search engine first meets it: the title, the meta description, the snippet that shows in results and the heading outline. Our pick is the seogeoaeo.ai On-Page SEO Checker, which covers all four for 8 credits a run and can also grade the page against the query you want it to rank for.
Most on-page problems are small and fixable in minutes. The hard part is seeing them, because the browser shows the page, not the tags behind it.
What the checker reports
| Item | What you learn |
|---|---|
| Title tag | Whether it exists, its length, and where it clips in results |
| Meta description | Whether there is one, and how it reads as a snippet |
| Snippet preview | The text a searcher is likely to see before the cut |
| H1 to H6 outline | Whether the headings form a clear order under one topic |
| Target query (optional) | How well the title, H1, URL and body cover it, and which words are missing |
Each run ends with a list of changes ordered by priority, each naming the page it applies to.
Titles: front-load the words people search
Google sets no fixed length for a title. It shortens title links to fit the width of the screen, which on desktop works out to roughly 50 to 60 characters. So the useful question is not "is my title too long" but "do the words that matter come before the cut". The checker shows where the clip falls, which makes the fix obvious: move the search terms forward and push the brand name to the end.
Google also asks for a title on every page, and for titles that differ from page to page. Repeating the same title across a section makes those pages hard to tell apart in results.
Descriptions: written for the click
Google says the meta description is not a ranking factor, and it builds most snippets from the page text itself. It uses your description when it judges it a better summary. That is still worth having, because a clear, page-specific description is the one snippet you control. The checker flags pages with no description or one that will be cut short.
Headings: one topic, then sections
Google accepts more than one H1. A single H1 that states the topic, followed by H2 and H3 sections in order, still gives readers and crawlers the clearest outline. The checker prints the full H1 to H6 tree, so skipped levels and stray headings in footers stand out.
Add a target query when you have one
Leave the query field empty for a plain tag check. Fill it in, for example with "trail running shoes", and the run grades how well the title, the H1, the URL and the body cover that phrase, and lists the query words the page never uses. That is the quickest way to see why a page ranks for something close to your target but not the target itself.
What it does not do
It does not show live rankings or search volume, and it does not write copy for you. It also reads the HTML the server sends, so tags injected by JavaScript after load are not seen. If you need rankings over time, pair it with Google Search Console.
