    Google have explicitly said that they do not use the Meta Description tag in their algorithm.

    While a good description tag (if used as the snippet) does lead to more clicks from the search results which would benefit the CTR of search results (although I’m pretty sure Google have said they don’t use that as a factor either).

    Hope that clears it up.

    Thanks
