Hitsplitter is a tool for executing comparative searches. If you have just released a book or a music album you can use it to figure out in which sites you are garnering the most mentions. You can also turn to the site in order to learn more about any new product, and measure how positively (or not) it has been received by those in the know. And the actual search process is going to be 100 % accurate if only because you are the one specifying where the search is going to be focused. You can keep everything centered on the top 20 newspapers in the US, the top 50 tech blogs, the top Wikipedia domains…
Besides, you can specify how far back you want the search itself to go. You can take things as far as a full year if you want, and you can also keep things closer at hand by looking at what has been said in the past 24 hours only.
And some of the best searches that have been carried so far are actually highlighted on the main page, for you to realize what to expect from Hitsplitter if you do give it a try.
