If you were to create a rule of thumb for web 2.0 marketing, what would it be? Basically what I'm asking is, lets say your goal was to jump into a market and only use a web 2.0 property as your site. What kind of numbers would you look for to rank that site on the 1st page with in a couple of days.
For example, some people say looking for competition with less than 50,000 results in quotes "". Some say less than 100,000 with quotes.
If you had to rank a site in a few days, what numbers would you look for? And backlink numbers if you want to put those in also.
