In my opinion, the approach you are taking is wrong from the very get-go.
You don’t get good, consistent ranking by trying to outsmart the engines. They ALWAYS catch up to you, and you are in for a life time of tweaking and worrying and changing your approach and learning more SEO and basically working your butt off outsmarting the likes of businesses the size of google et al.
If you get your kicks that way, fine.
If you are aiming for a solid business that makes good money in the long run without all that worry all the time, spend your time figuring out what they want and do that.
It ain’t smart to try to outsmart those who you depend on for a living. They will forever have the upper hand. Just please them, it’s cheaper, easier, and a lot more successful in the long run.
