I basically know what to look for when doing keyword/keyphrase research, and I'm sure there is no perfect formula to finding the best keyword, but I was wondering if those successful can provide some information on the minimums for each of the questions I have. 1. What would be the minimum Local Search amount to get "some" traffic started? I've seen people say 1,900 or so, but can you go down to 750? Why / why not? 2. Whats the minimum page authority? If Top 10 have 20 - 40 PA can you compete? Should it be lower? 3. Page Links. I've seen people say 100 or less. I guess I'm grinding my gears here trying to find the "Perfect" keyword/keyphrase. If I had a pretty good idea on these variables I could actually start creating my site. Thanks for your advice.
