How do you determine the value of keywords? One variable is the amount of visitors it is able of bringing. But the amount of traffic isn’t all. You’ve got to be in a position to sell to that traffic. One of the ways to determine the commercial viability is the pay per click CPC the advertisers pay to display their advertisements for that keyword. Most tools provide this info, from Google’s External Keyword Tool to Keyword Elite. If the keyword has a high cost per click, means advertisers have gain from it. If the bid price per click is low, there’s likely very few buyers looking for that phrase. Pay attention to this variable when researching, the volume of traffic and competition is not all.
