I have a 9 year old site. About 7300 backlinks in total. I built 2 new posts and threw some AutoFill Magic web 2.0 links at them. How many backlinks can I build without getting the search engines excited in a 3 week period. So: Old blog, new posts. How fast can I build links to the new posts. for instance I want to target 48 Long Tail Pro KWs to the post. All the KWs have super low competition and super low visitors but with all of them working together I might be able to get some traffic. Also, is there a rule-of-thumb ratio for how many KW phrases I should use and how many generic "click here" I should use.
