I have some two month~ old websites that have been dancing for the last 2-3 weeks, one has just returned from a dance (just realized how weird that sounds). The others are still currently dancing. My questions are: Does adding quality links to them before they dance or while they are dancing determine the amount of time the dance will last? Are there any other factors that influence dance time? I read some article about the dance being caused by google server updates, is this true?
