The market analysis tool works as follows:
We have 30 million keywords in our database, and we search the Google search engine for those 30 million each month and on the first page.
We collect all the results from the first page.
By performing a reverse directory system, we can know the keywords of the database on which a domain appears. However, we do not have all the keywords where the site advertises but only those where the site is present among our database of 30 million keywords.
This tool thus makes it possible to identify trends between a site and other sites in order to be able to compare them on a 30 million keyword repository. It is not necessarily representative of the overall traffic generated.
