The Google Dance

Over on our Cinnamon Edge blog, we talk about one of the mysteries of Google search results - how a perfectly good website can be listed one day and apparently de-listed the next, and how this 'Google dance' often ends with that site higher in the results than it was before.

But there's another version of the dance, and Google stages it weekly.

It's a result of Google's regular updating of its search results. Google's problem is that it can't close down its service for a second, so updating has to be done in stages, across 10,000 servers worldwide. So at any one time during the update process, some of the servers will have the updated version of the results and some will have the old version.

With 10,000 servers to choose from, there's a good chance that the results of any fresh search you make will be delivered by a different server than the last one. So you will often see websites move up and down the search results with each search you make. This means that websites appear to 'dance' in the results, and this only ends when all 10,000 servers have been updated.

Between updates, websites can also move up and down the results as new sites are indexed, links are followed and websites are updated and improved.

But they dance most energetically once a week, usually on a Monday, apparently, when Google re-jigs its results, server by server, across the planet.
