Here are some simple but at the same time very important tips to improve your hub and increase your revenue.Different styles may be used .Some among them are as follows:

1. Promote Your hub very efficiently.This can be done effectively by providing links in some discussion forums and sites like Digg, StumbleUpon, Reddit, Mixx, Propeller, IndianPad, Masalatalk etc.Catchy Titles must be provided while posting in these sites.
2. Choose top paying adsense keywords in your hub's text so that the chance for occurance of relevant and good ads increases.For this you may use Google's Keyword tool.Many other means are also available in the net

3. Remember to use the important keywords frequently in your hub at proper places.Keep in mind the fact that the reader will be bored if the frequency of the same keyword increases beyond a limit

4. Add channels of all your hubs seperately in your adsense account so that you can track the best ones and improve the worst.
