I wanted to share a couple of things I found today. I was browsing around looking for more info about the Google dance, what happens during the dance, how long does it last, etc. I found this article written in 2015 but still seems to be relevant: https://semanticmastery.com/google-dance/ Now I don't know if that's been posted here before but it's well worth reading anyway. But the more interesting article is the one he links to, which is a US patent document: http://patft1.uspto.gov/netacgi/nph...8,924,380.PN.&OS=PN/8,924,380&RS=PN/8,924,380 The patent title is "Changing a rank of a document by applying a rank transition function". Rank transition function being what we all know as the Google dance! If you have never seen that document before, read it now. Everyone on BHW should become familiar with it. I'm sure some here have, but I'm posting it for the ones who haven't. I had thought that the dance was some kind of manifestation of the way Google recalculates your rank after finding a link, maybe it had to reset some things which is why your ranking drops. But no! It is a deliberate ploy by Google to try and trick you into undoing whatever you just did. Not only that but there are all kinds of different patterns it can apply during the dance. You may drop and slowly rise up. You may slowly drop and then suddenly bounce up. They have a random selection of transitions they can apply. Read the stuff after "Exemplary Rank Transition Function". It's fascinating. You learn that not only might they apply this transition function to the site being linked to, but possibly other sites on the same server! And that the whole thing can last up to 70 days. There is one bit that seems to be saying that trying to increase the rank of a document for keywords it already ranks for could be a sign of spamming / manipulating. Not sure if I've read that right. I feel I learnt some important stuff reading that, I hope some others here do too.
