Was experiencing a loss of visits since i installed the adSense banners..
Searched all the blog for the problem and well noticed there where no visits from google anymore, no keyword source traffic.
Dunno how i did it but i removed the great plugin (find it in About page) for WP, called Meta SEO Pack.
This plugin does all the indexing of your site for you (combinated to search engines work obviously)
Have a look at it. And i’ll keep an eye at my stats from now…
