Well search engine sometimes make a quiet move on when dancing will happen. This will make a fair competition and equal process for the change of algorithms.
wow something new i can learn form this board so people please continue and let me know more bout this topic thank you all
google dance occur frequently with no fix period, you cant really get the date It can be 10 days, 20 days or months
in my opinion no one cant predict the GOOGLE Algo. Like generally google updates the PR after every 3 months but no major update we saw from the last 9 months.... So Google is unpredictable
The major Google index update occured on average every 36 days or 10 times per year. It was easiest be identified by significant changes in search results, and by an updating of Google's cache of all indexed pages.
