Today I wanted to integrate some SEO in my blog and I've seen that a yandex plugin offered a number of options. I've also seen there's a difference between google analytics and their webmaster tool:

Webmaster Tools reports on how search engines interact with your site, while Google Analytics reports on how website users interact with your site. Whether you are personally managing your brand’s digital presence or working with a third-party, both Google Analytics and Google Webmaster Tools provide valuable and actionable information.

Cool!
