A question to those who run several adwords campaigns. How do you determinate what goods are hot right now, and what will be hot in the future? I know it's not a simple question but any suggestions will be much appreciated Do you trust the google trends? What other sources would you recommend to see what's hot? Thanks
read consumer reports and watch for product releases and pre reviews of products that are going to be released.
the google keyword tool gives you a search volume so search for a product and it should show you keywords for other related products, look at the search volume for that month in comparison to others, should give you an idea.
