I was recently asked about what kind of SEO tools exist for products. The best tools are the easiest tools.
E-Bay pulse provides excellent data on what those visitors are searching for. Check out the top listings at pulse.ebay.com. You’ll see in a moment how reliable this data is.
Google offers excellent data through their Google Trends service. While trends will show you news results, Google Insight – a more in-depth version of Trends can be tweaked to focus on only product data if you are so inclined.
I have no experience with it but I have heard that the Amazon API may have a hook that you can access for the same data.
Anyone else have some recommendations?
