On-Page SEO Audit as a checklist
It takes one URL and returns an audit sheet: what passes, what warns and what has to be fixed today. Every item comes with its reason, not just a tick or a cross.

The short answer
On-page SEO is everything on the page itself that is under your control: the title, the meta description, the heading structure, image alt text, internal links, the canonical and structured data. This tool reads all of them in one run and tells you which ones do not match what Google expects.
Two items on this list matter more than the rest, and the others are details next to them. The first is the title tag: the only thing on the page that both affects the ranking directly and decides whether somebody clicks your result or the one below it. The second is the canonical, because a wrong canonical can tell Google this page is not the original version and effectively remove it from results, with no error message anywhere.
The item that is always red and almost never fixed is images without alt text. The reason is that it looks like a lot of work for little return. Its main return is not SEO at all, it is accessibility: somebody reading your site with a screen reader hears an image with no alt as a file name. If you run a shop, correct alt text is exactly what gets your product photo into Google image search.
Page weight comes in the same report and is best read next to the speed test result. A heavy page is not necessarily slow if it loads well, but a heavy page on Iranian mobile internet almost always is. If the weight figure is large, go to the images first; on real projects most of the page weight is usually there.
What you get back
What each output column actually means. Read this before your first run so you do not misread a number.
- green
- Green (healthy): no change needed.
- yellow
- Yellow (warning): acceptable, but there is room for improvement.
- red
- Red (error): should be a priority to fix.
Where the data comes from
The check runs without executing the page JavaScript (faster and cheaper); if your page main content is rendered by JavaScript, some items (like text or links) may not show up in this report.
When it helps
Before publishing a new page, or when investigating why a page performs poorly in Google.
Where it does not help
The audit runs without executing the page JavaScript, which is faster and cheaper. If your main content is rendered by JavaScript, some items such as text or links may not be seen here and the report will be more pessimistic than reality. But that cuts both ways: Google also sees this same raw HTML for the initial index and defers JavaScript rendering to a separate, slower queue, so an empty item here is not necessarily a tool error, it may be exactly what Google sees at first glance too. The second limitation is scope: this tool audits one page, not a whole site. For problems that only appear at site scale, such as orphan pages or duplicate content across categories, it is not enough.
One thing we learned using it
When the report says a page has two H1 tags, nobody usually wrote two on purpose. Almost always one of them is the logo in the theme header coded as an H1 and repeated on every page of the site. So it is not a flaw in one page, it is a flaw in the theme, and one change in the header fixes it site-wide. Before you go looking page by page, look at the theme header.
What it costs
No monthly subscription. You top up a wallet and the price of a run is printed on the button before you press it; if you never run it, nothing is deducted.
Questions about this tool
What is the right length for a title and meta description?
Google truncates by pixels, not characters, so there is no exact number. The range the report warns on comes from that calculation. More important than hitting a number is putting the most important word near the start of the title, because that part is never cut.
How is this different from the speed test?
This one says what the page shows Google, the other says how long it takes to show it. For an important page run both; neither replaces the other.
Do all items have to be green?
No. Some warnings are correct for some pages. A category page naturally has less text than an article, and that is not a fault. Read the report as a list of things worth looking at, not a list that must be turned entirely green.
