On-page SEO checks for titles, descriptions and headings
The checker extracts the HTML title, meta description and heading structure directly from the fetched page. It reports character counts so you can spot missing or unusually short and long metadata without assuming that one exact length guarantees how Google will display a search result.
It also checks the H1 count, image alt coverage, internal and external link counts, mobile viewport and detected schema types. These signals help answer long-tail audit questions such as whether a page has multiple H1 tags, missing image alt attributes or no structured data.
Technical SEO and indexability signals
A page can have strong copy and still be difficult to crawl if the final URL redirects unexpectedly, returns an error, declares noindex, lacks a canonical URL or sits behind a robots.txt rule that blocks crawlers. Toolmera surfaces those signals next to the on-page report instead of separating them into unrelated dashboards.
The checker also tests robots.txt and sitemap availability for the final origin. This makes it useful as a lightweight technical SEO audit before opening Search Console, crawling a full site or investigating why a specific URL is not being discovered.
What a free SEO checker cannot prove
A live URL scan cannot determine whether Google has indexed the page, which queries it ranks for, how many backlinks it has or how much organic traffic it receives. Those require Search Console, backlink indexes, analytics or other datasets.
Use this report to fix observable page-level issues first. Then validate indexing and search performance with first-party search data rather than treating any third-party SEO score as a ranking guarantee.
