How can separate keyword phrases that adwords traffic estimator predicts will generate the same clicks, generate vastly different organic search statistics for a single page ranking equally well (page one) for both keyword phrases. We are talking about around a 10 times difference.
Ex. one phrase produces one number of pageviews the other produces over 10 times as many.
Must it be that the page title and description showing up in the search results have such a difference in viewer behaviour? That is all the searcher would see. 10 times the difference in organic search behaviours when equal prediction via adwords traffic estimator?
