Well google wouldn't pay you more then $10 for a click. I haven't heard of anyone get paid a lot. lol
A very reputable tool to find out the latest rates of the keywords is this: http://spyfu.com/ Just enter any keyword you want to know the rates of and it will tell you the minimum and the maximum range of cost per click, the no. of advertisers currently paying for that particular keyword, the approximate no. of search results, the approximate no. of clicks per day and even show you some of the actual ads. Here are the results of the keyword "mesothelioma" Cost/click: $1.71 - $28.48 Advertisers: 21 Clicks/Day: 175 - 221 Search results - 26,400,000 Cost/Day - $298.34 - $6.29k You may also like to find out the no. of searches per day. Here is one of the top tools: http://freekeywords.wordtracker.com/ In reality it is not simple at all. You need to find out first the keyword which seems profitable enough, then use the wordtracker tool to find out the related keywords, find out the competing sites for that particular keyword, then find out the results with the exact keyword in it and so on. After that you would need a related domain name for the keyword (like womensselfdefense.in for the keyword "womens self defense"). Try to go for a dot com extension as far as possible. Coming up high on a top keyword is not easy, the biggies are always on the go. The best option is to dig deep and come up with a keyword with sufficiently high payment but low enough competition to be able to rank high. And that is no mean task. Forget about any list of profitable keywords. The Internet is constantly changing and the scenario can change overnight. Find out one keyword, and stick to it. Keep working on getting your site high on the keyword and then you may expect to make something out of it. Promotion is another important aspect. The best designed site on the highest paying keyword is like a tiny island in the Pacific if there is nobody to see it. PPC, Bum Marketing etc are good approaches. Whatever the approaches, just stick to it and you would surely see some results. Hope it helps. Anil Pandey
