Just a term used to describe an algo update I believe, which in turn can change a websites ranking, pr, etc

Google Dance is often used to describe the index update of the Google search engine. It is an out-dated slang term used to describe the period of time in which Google used to rebuild its rankings, and as a result of this rebuilding, rankings of Web sites on Google's SERP may fluctuate in order during a several day period.

I've experienced the google dance quite often in the past. Its usually when you set out doing some serious SEO, like a backlink campaign - while google registers the new incoming backlink and tries to make sense of it you may get an initial boost, then a significant drop, and at last the final adjustment which usually ends you up on page 1 or 2. This usually happens when the specific keyword is receiving heavy backlinks for the first time or so. After that its a smoother "climbing" when you continue with the same keyword.

I never heard of Google Dance. It sounds funny. You can probably find out about it by searching online at google.

It's a term defining changing PR of website after an update of indexes

Now, what is Google Dance, i suffer it everyday...

Google dance is concept made different view by different user. Actually what happen google server is divided into 3 parts.
1> Google
2> Google Bot
3> Google fresh-bot. And once we see result is of fresh-bot then next result we see is of Google bot and lastly we see result is of Google. So many times it happen our site been shown on the top and after some day it been not in the listing also.

So many answers....Google Dance is mostly experienced when doing heavy link building. Once the links are getting indexed you can notice some major ups-downs in SERPs, the best method for fighting with this is continuing building links until things settle down.

Its about the sudden changes in SERP. Sometimes when Google is updating their algorithm to make sure they would rank only good quality natural website, SERP of many websites changes a lot. It can be due to the traffic changes on your website.
