This then brings up the question of: How good are your prices? How good is your site?

Getting hits can be easy, it's getting leads form those hits that count. From experiencing and asking around it seems hit and miss depending on how monetized the site is. With how competitive hosting is and the ROI on one sign-up it really can be hit or miss. One month for a non-hosting site I was getting $40/m in $90/m out until I put more google ads + affiliates on the site.

The problems with using adsense for hosting sites are the hits are not always well targeted and can end up on sites that have nothing to do with hosting. You have a better chance of getting a signup from someone who was recommended to you or saw a forum ad.

I agree, keywords are prime. There are many keyword trend sites to get better keywords with.

Make sure to always focus on conversions and ROI, not just merely trying to get traffic to your site.

I 'm going to try it in the future, but I think it is very expensive especially in WebHosting industry.

Would you please share your experiences with us?

You need to be creative when coming up with keywords for adwords. It is quite crowded on google and terms such as "web hosting" are very expensive.

adwords can be effective but don't get stuck in the generic term game, you'll be broke trying to land a $10 account.

We have used adwords in the past and still using it. But the only difference is earlier we had all the keywords we could think of and we displaying ads in almost every country. Now, scenario has changed. It has become very expensive, almost 1 click to one dollars and sometimes more on certain keywords. So we have narrowed down on a few keywords only and limited to certain states and territories. It is an expensive affair altogether.
