Most-used search algorithms

Google:

  • Unnatural links: the search engine tries to fight against websites that use spam. It targets websites that try to manipulate rankings through artificial links.
  • Mobile friendly: Google favours mobile-friendly websites.
  • SSL code signing certificate: websites with this certificate get higher SEO rankings.

Yahoo!:

  • Keyword in URL: this search engine favours these key words more than Google.
  • Page title: Yahoo! gives relevance to the page title. The main difference with Google is that it is not strict about the repetition of keywords in titles.
  • Domain age: unlike Google, this search engine still takes domain age into account.

Yandex:

  • Meta keywords: this search engine takes into account meta keywords to determine if a page coincides with a search.
  • Paid links: these are considered valuable for SEO, much more than in Google.
  • Spam links: Yandex does not use these links in its algorithms.

Baidu:

  • Meta descriptions: like Google, Baidu uses descriptions as a key factor in SEO. One or two key words must be used, together with a brand term. The maximum length will be 78 simplified Chinese characters.
  • Multiple domains and subdomains: Baidu is not interested in this these. If it is a multilingual website, you should use another domain that should not be linked to the Chinese version.
  • ICP Licence: obtaining this type of licence through China's Ministry of Industry and Information Technology will greatly improve the organic search ranking.
