For most internet marketers like me, I will rely heavily on keyword research tool to find profitable niche. Most keyword research tools like Google own Keyword tool gives you good information on how competive a niche is based on the number of searches and advertiser competition. It will also generate keywords list for you based on the a website URL .

For example, I did a search on weight loss on google and found this website http://www.lookcut.com/

I enter the website in Google Keyword Tool and it generates a list of useful results for me in seconds!

From the results, you can see what keywords are getting high search volume for the month of July.

You can also check the number of advertisers advertising for the keywords.

Based on all the results, all I can say that weight loss is a very very competitive niche and of course very profitable if you can get your website to the top 10 rankings just like http://www.lookcut.com/

If I want to going into this niche, I will use a powerful keyword research tool like Keyword Elite to help me find keywords with less competition and reasonable monthly searches a month.

So how does Keyword Elite help me?

First of all, I will use KE to generate 1000 keywords for me related to weight loss.

Then I will use KE again to analyse the 1000 keywords based on number of searches and competiton.

Once I have got a list of low competition keywords with about 10,000 searches a month, I will use KE to sort the keywords into different category.

The sorted keywords will be used for my Adwords campaign to promote a good weightloss ebook which I have found from clickbank.

You have to test your campaign by doing split test using ad groups to get the best conversion. Higher conversion means more money.

I am just giving you an overview of how you can find a profitable niche product to sell. Getting a sale involves more than testing your campaign. You also have to test your landing page, the headlines, sub headlines, call to action because your landing page will be the first thing people see when they click on your ad.

So you have to engage your visitors to do something on your landing page like signing up for a newsletter about weight loss. Once they signed up, you can follow up with them until they buy from you. This may sound like alot of work but once you have perfected your campaign and landing page, money will flow in automatically.
