A page URL
Status, redirects, broken links, internal links, duplicate links, anchor text, orphan pages, meta tags, canonical, indexability, Open Graph, schema, hreflang, SSL, favicon and image alt text.

One URL in. A clear next step out.
Every checker follows the same rhythm: choose the symptom, paste the input, read the evidence, then fix the cause.
The four-step loop.
You do not need to learn the whole vocabulary first. The page names the element and the fix.
- 01
Pick the symptom
A 404, a redirect, a page that will not index, a missing canonical, a social card with no image. Start with what you can see.
- 02
Paste the right input
Page tools take a full URL. Host tools take a domain. The ranking check takes a keyword and a domain.
- 03
Read the evidence
The result shows the code, tag, certificate or link list behind the answer, so you can verify it instead of trusting a score.
- 04
Open the guide or the app
Each tool page explains what the result means and the fix. When you need every page, move to a full-site crawl in the app.
What to paste.
Most tools take one URL. Three kinds of input cover the rest.
A host
robots.txt, sitemap.xml and the TLS certificate are read from the site root. Enter the domain and the tool finds the file.
https://example.com
A keyword and domain
The ranking checker needs both: the search phrase first and the domain second. The live position is checked in the app.

Free limits, stated plainly.
The browser demo is a real check, not a sample result. It is limited so the app can stay sustainable.
10 free checks per browser
The counter is stored in your browser, so it survives a page refresh. When it reaches zero, the demo card asks you to sign in and hands you to the matching tool in the app.
The free tools check one public URL at a time. They do not crawl the site, save a history or remember a project. That is what the app adds: every page, every internal link, a health score and one issue list with fixes.
A target gets a normal request, the same one a browser would make. The demo does not log in, submit forms or change anything on the target site.
Do I need an account to use a checker?
No. Load any tool page and run up to 10 checks per browser. An account is only needed for the full-site crawl and the tools that live in the app.
Why does a tool ask for a host instead of a URL?
Host checks read a file or certificate from the site root, such as /robots.txt, /sitemap.xml or the TLS certificate. Enter the domain, for example https://example.com, and the tool finds the right resource.
Why does the ranking checker open the app?
Live search positions need a search data source and a saved project. The browser page explains the check and hands you to the app, where the keyword and domain are remembered.
Can I check a site I do not own?
Yes, for any public URL. The demo only reads what a normal browser could read; it does not log in, submit forms or change anything on the target site.
Where do I see the full issue list?
Run a full-site crawl in the SEO app. The free tools show one URL at a time; the crawl maps the whole site and groups every issue with a fix.
