I'm looking for a tool for searching a list of 100 specified websites/blogs for my specified phrases and terms. With this tool you could very quickly make blog comments on threads that are relevent to your websites. This will make your post appear more relevant to the thread giving your backlink more chance of survival...you can see where I'm heading.
So Google will let me specify one site to search one key phrase. However I want to search many specified sites for a variety of keywords and phrases. Do you know a search engine that will let us do this task? Any programers like to offer a quote to develop one?
