Yandex announced changes in the bypass of AJAX sites by robots. Now, instead of checking HTML versions of pages, robots will execute scripts on AJAX sites.
Pages with #! are no longer supported. In order for the content of the site not to disappear from the search results, you must:
- Change the structure of links in the sitemap so that their content does not contain the # symbol
- Set up 301 redirects on pages that are important for the state of the site to new ones with correct addresses (namely, without the #! parameter ). In this case, redirection must be configured both from pages to addresses like http://www.example.com/?_escaped_fragment_=blog , and from pages http://www.example.com/#!blog .
