I don't get many visitors from search engines. Some i am wondering - are they important to your sales? Do they attract many visitors/customers to your site?

You could ask yourself a question: what do you do if you want to find a nice game for yourself?

*You can ask you friend
*Or you can check some game review site
*Or you can use google to find one

So it may not be the most important way to attract customers, but it definetely is one issue to take care of.
