Where do you obtain your search volume data?
We obtain the search volume data from Google Keyword Planner. Along with volume, we also get the CPC and Adwords competition from Google Keyword Planner
Where do you obtain search volume for Amazon, Youtube & eBay from?
Other than Google, none of the other companies release their search volume. We therefore, show the search volume, CPC, and competition metrics from the Google Adwords API for all the searches at Youtubetag.com. Since the search volume for a keyword at Google and Amazon/Youtube and other sites will be proportional, one can easily compare keywords based on the Google search volume.
Do you provide an API?
We don't have an API for accessing our data. The only way to do so is by using our web-based tool.
