TRY ADSENSE 1

If you have noticed properly, there are advertisement against our blogs which reads something like this
” Have a blog? Earn revenue from relevant ads – Try Google AdSense”, which was provided by Google AdSense against our post. What does this mean?

Shall we think that google is inviting us to join AdSense or it is the eBlog who is giving us a platform to subscribe adsense? If we join google can we give this eBlog site for advertising the advertisers products?
