I own a bunch of websites and I see ridicoules inconsistencies. Take for example, "Free Games" VS "Tower Defence". Trends shows that "Free Games" gets a hundred times more searches. Yet I have websites that rank #3 for both terms, and I only get X5 traffic for "Free Games". I get many other inconsistencies as well.
Is there any way to get reliable Google search volume info? I use KeywordDiscovery.com but it's about as bad as Trends.
