Overview: Google understands and interprets the following meta-element attributes
According to Google, the meta-element attribute “description” is not part of the ranking calculations for the search results. Though, it does play a significant part for the CTR (Click-Through-Rate) of users and should therefore not be forgotten. A good structure for a meta-description optimisation is the AIDA-Principle.
Nowadays, Google ignores the meta-element attribute “keywords” and you need not worry about using it, at all.
