Try Google Webmaster Tools Promotion
I have noticed the Google is promoting Webmaster Tools on search queries of the format “site:domain.tld” and it makes sense since such a campaign would be targeted to webmasters. I mean why would a normal user be looking for how many pages are indexed for a certain domain?
Anyway, what I found a bit funny is that you see the promotion even for some google domains.
Do you own google.se? Get indexing and ranking data from Google.
I wonder how many would actually click on that ad !
