I started using Yoast solution a few months ago for the SEO of my blog http://www.frenchtouchmusic.com
Since then, I noticed that the results on Google are not as accurate as they used to be. For example, the description of my blog in Google results is not the same as my Meta description. The description changes every time I write a new post and shows the meta description of this post.
Do you have any idea why and how I could change that?
