Why do my blog have ads ?
With the increase of users, Overblog platform must be updated to always be efficient. Our goal is the divide in equal way the maintenance costs between all bloggers : Premium members through their subscription and Free members through ads on their blogs.
Being a Premium member will give you the opportunity to remove those ads on your blogs if do not want them anymore. More infos on Premium !
You're a Premium member and you remove all ads on your blog but you still continue to have some ? Those ads do not come from Overblog.
Those ads may come from your browser which use your navigation history or from a tools bar which displays ads. Test with another browser or another computer to notice that those ads are not showing on your blog.
Ads can also come from a widget on your blog. Some of providers of widgets are said free but, they display ads in return.
