Hi
Our crawl report detects that we have not put in a meta description for any of the tags we have used on our blog. (total tag words we have used is around 70). We have however, put a full description of each of our categories, do we really need to put a description for each of the tags we use? Will this really help us with SEO? Also can tags on posts be the same as the keyword your trying to rank the post/article about?
For further information We are using Yoast.
