On-Page SEO Audit as a checklist
It accepts one URL and hands back an audit sheet: what is sound, what warns and what needs fixing today. Each item carries its reason, not just a tick or a cross.
- A colour-coded audit sheet
- A reason beside each item
- Canonical and schema covered too

The short answer
On-page SEO is everything on the page itself that you control: the title, the meta description, the heading layout, image alt text, internal links, the canonical and structured data. This tool reads them all in one run and points out which do not match what Google expects.
Two items on this list weigh more than the rest, and the others are details beside them. First, the title tag: the one element on the page that both affects the ranking directly and decides whether someone clicks your result or the one below. Second, the canonical, because a wrong canonical can tell Google this is not the original version and effectively drop it from results, with no error message anywhere.
The item that stays red and rarely gets fixed is images with no alt text, because it looks like a lot of work for little gain. Its main gain is not SEO but accessibility: someone reading your site with a screen reader hears an image without alt as a file name. For a shop, correct alt text is exactly what puts your product photo into Google image search.
Page weight sits in the same report and is best read alongside 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, start with the images; on real projects most of the weight is usually there.
The output you receive
The exact meaning of each output column. Read this before your first run so you do not misread a value.
- green
- Green, healthy: nothing to change.
- yellow
- Yellow, warning: acceptable, but it can be improved.
- red
- Red, error: belongs at the front of the fix queue.
The data source and method
The scan runs without executing the page's JavaScript, which is faster and cheaper; if your page builds its main content through JavaScript, some items such as text or links may be absent from the report.
The situations where it helps
Before a new page goes live, or while tracing why an existing page underperforms in Google.
Where it falls short
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.
A lesson from working with it
When the report says a page has two H1 tags, nobody usually wrote two deliberately. Almost always one of them is the logo in the theme header coded as an H1 and repeated on every page. So it is not a flaw in one page but in the theme, and one change to the header fixes it site-wide. Before searching page by page, look at the theme header.
What it costs
There is no monthly subscription. You raise the wallet balance, and the price of each run is written on the button before you press it; without a run there is no deduction.
Common 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 figure. The range the report warns on comes from that calculation. More important than hitting a number is placing the key word near the start of the title, since that part is never cut.
How is this different from the speed test?
This one reports what the page presents to Google, the other reports how long that presentation takes. For an important page run both; one does not stand in for the other.
Do all items have to be green?
No. Some warnings are right for some pages. A category page naturally has less text than an article, and that is no fault. Read the report as a list of things worth checking, not a list that must all go green.
