Meta tags.

Tags site description, tags, authorship, keyword tags - all tags are less and less overlooked, but give. A good habit is to fill those tags. I would even say - self-respecting site must fill them. the more so that search engines use the description of the site in the issuance of the search and that is what people read before they go to the site. Recommendation will be very simple description of the site (description) to be sold, that is only for people, keywords (keywords) is not very much - just 3.5 of keywords and make sure that these words would be attended on the page.
