The interesting thing here is with those millions being spent, you’d think they would put the money into SEO to push their primary keywords to the top of the listings, but it appears that they are not doing this. The companies are still improving on their listings, but it’s still a minority that are even breaking the top 50 in the SERP list for their primary keywords.
