Using free websites is a great way to test stuff out such as the adsense thing, because there is no investment except your time and hard work i you can be bothered that is, Adsense for search is good if you know really what to direct your visitors to search for, but it also requires alot of traffic to sustain any income.

Free websites are all the rage for new internet income seekers, but some if not half of them end up doing things completely the wrong way round and fail or give up because they don't get the results that they wanted, free blogs are even more easier as there is a little more control of the content especially within a hosted Blogger account as you can add the code for a search bar from your adsense account on your blogs sidebar and even other affiliate banners and text links.

Again adding the adsense for search function is easy, getting traffic to it is something entirely different and more complex in the online marketing world and this is what makes alot of first time webmasters and bloggers give up with frustration.

The best thing about adsense for search is when you have built up a site with lots of content and you can then have people search through your page archives and each click earns you money whilst still staying on your site.
