How to test a website on "acceptability" for robots Google and Yandex?

Hello! Please tell me what could be wrong - the website is not visible in natural search. The domain and the shop has been around for 7-8 years, people come, and through advertising of Yandex/Google it to see, but in natural search it no 1 page no 7.

What key factors should check in the guts of the website and admin area to make sure the technical side (well, at least the basic SEO) are all set right ?

Check whether the limitation on the indexation of the site in robots.txt so I recommend to check whether the metatags of the website such tag if there is remove.

It is necessary to add a site in Yandex.Webmaster and Google webmaster tools through time after you add You will be told the reason for the lack of website in the index.

With all this, the site is a virus, usually the sites with viruses are removed from the index of search engines.
