I read a discussion recently that the cheapest way to get indexed by Google is to put Adsense on the new site. The theory behind is that Googlebot will need to index your site first before Adsense can display the ads.
Yes, it will definitely be the cheapest way to be indexed instead of paying for the PR6 link.
Well, do you think it works?
I tested this, I created a new blog, I turned off Ping, I fed in some content and I put in some Adsense codes.
I waited for 1 day, 2 days, 3 days and it has been a 2 weeks now. My new blog still not yet indexed by Google.
So, Adsense is the cheapest way to index new site. I think this is just another BS.
