Many may already be aware of these facts but many may not... I started this page yesterday and it is not finished but may have some useful info on this subject so I have decided to upload it to my website now for folks to read now. Remember, it is not finished. It is just meant to be a little helpful. About Google Datacenters Scroll down to the section - Why care about results on different Datacenters? Caryl
Yeah, I've noticed the switches in the past- Im actually getting one of the DCs with the new results ATM. Check http://www.mcdar.net/dance/index.php for Search Engine Optimization, SEOInc.com isn't #1..
Nice summary on the datacenters. Over a year ago I read a post where someone had noted the SERPs routinely changed on the same datacenter over a 24 hour period. I think his read was datacenter A serves the most meaningful data to that portion of the world that was awake at any given point in time. Your tracking validates this variation in SERPs but probably not the part of the theory of serving most meaningful date to those awake.. Shannon
I'm really glad you started doing this when you did, very interesting picture of how things are unfolding over the datacentres.
Or perhaps just different filtering. A couple of my sites really got hammered. One of them went from #3 for its own name to not being in the top one hundred for its own name. Mostly this update looks to be beneficial for me, but not completely. I can't make a reasonable pattern from the data I am seeing. Some go up; some go down. I can't figure out what puts each page+keyword into which group.
I have actually seen the pages returned go up vastly But results do seemed to have reverted to poor cr*p again
Bugger! I wonder if the cool results were minus a filter or a test run on something else. I sure was hoping they would move accross all datacenters.
