Speed of implementation is everything.
Just recently I sat with two high profile internet marketers (one of which does over 10M a year) ...and he said to me ...
"Put up 10 sales pages with buy buttons. Find the ones that make sales, and flush the rest" - repeat repeat repeat.
Find what works and do more of it. Stop trying to cut corners. Treat it like a business. Build quality products. Offer high quality services. Quit wasting time.
While you're messing around worrying about what your sites page rank is, high profile internet marketers are rolling out several products and services.
