View Page Source
A page's raw HTML as the Yandex or Google robot sees it: SEO tags, counters and the site's engine.
The tool shows the HTML source of a page exactly as the server sends it: without running scripts and without the changes a browser makes.
In the user agent setting you can present yourself as the Yandex or Google robot. The page then shows what a search engine gets rather than a browser: some sites serve robots different code.
When there is almost no text in the source, the tool warns about it. Such a page is drawn by scripts in the browser, and a robot crawling it has nothing to index.
The tool pulls the page title, description, canonical URL, robot directives, viewport setting, and Open Graph tags out of the source. Problems are flagged next to them: an empty title, a title that is too long, and similar issues.
Counters, analytics systems, and the site engine are detected separately: Yandex.Metrica, Google Analytics, Top.Mail.Ru, WordPress, Bitrix, Tilda, and others, fifteen signatures in total.
The tool shows up to 500,000 characters of source or 6,000 lines.
