Sorry but of the people I survey (at workshops, 20 Groups and webinars) and ask this question, 99% of them get it wrong
"What will get you more search results (SRPs)
1.Better photos
2.Better comments
3.More Competitive Pricing
4.All of these will work
5.None of these will work"
99% of the people say #4 and the video was to prove that it is really #5, those 3 things will not guarantee more SRPs
Common sense or not, I admit that I would have guessed #4. I would bet that a lot of others would have guessed that as well (if they would admit it).
I would have answered this thread "Is there really a science behind car pricing?" with a simple one word answer of No.
I am rethinking that now based upon what Jasen @LotPop has shared.
