Indeed. You have to realize that sometimes what causes the change is the LACK OF CHANGE on your site Just because you have all these backlinks and all that good content doesn't make Google happy anymore. They want to see that your site is being constantly updated with fresh relevant content. Hope that helps
What is the site in question? May be the sites you have linked to have changed and affected your rank.
Would every one agree that there hords of other webmasters out there who also want to be page 1 ,,,, for every keyword or keyword phrase you can think off ?
I don't think it was an algo change, maybe a minor fix. Some of my sites jumped up yesterday as well, but it's irratic.
It seems googlers changed something in their algos, Search Engine Update Monitor shows a growth on the graph for Feb,14. 48.5 % of sites have changed their positions..
That's interesting, seems like a bigger shake up. I see very different results on various data centers.
