| I dont think there is a rule such as the one you refer to in your post. It depends on what you are selling, your target market, and the perceived value of your goods.
Your biggest challenge is to get people to your site, encourage them to buy, and to entice them to return again.
A good method of tracking the effectiveness of your ads is to compare the cost of the ad versus the revenue the ad brings in - if you can measure such stats - then make a decision as to whether you are getting a good return on the cost/investment.
There are plenty of other tricks to entice new visitors such as joining lots of forums, providing exchange links, building an opt-in email list that you can market to, providing up to date and valuable information etc etc.
