Optimization of the site, what does it mean...?

SEO-specialist, specialist in targeting. In Studio Webmaster I work since 2018. More than 6 years in SEO. I like analyzing people and what is happening in the world, also to follow the progress of something. Video games help me to relax. The most favorite one — Half-Life 2. But, this is not old school this is the classic of science fiction genre :)
