A Backlinking Tool
Here’s a web tool that does a search for keyword-referenced places to plant backlinks.
Enter the keyword phrase in the search box and then choose the type of blog platform or web 2.0 site on which can be placed a backlink.
It should go without saying that in-context, non-spammy links are best.
http://dropmylink.com/ has a similar search tool that also locates posts for backlinking on .edu’s and .gov’s.
