I remember being very surprised at the speed in which new websites would appear in Google SERPS immediately post-Caffeine. I think it would take about 1 week from the day the site was created until getting a strong page 1 result. After the initial strong SERP showing, I would see the site shuffle back down into the SERPs at a more predictable position. Bing and Yahoo would take a little longer - about 2 weeks if I remember correctly.
Well, recently I've created 3 new websites, all in the same niche and very similar to some other sites I'm running which were NOT affected at all by these latest Panda and other updates. Well over 1 week has gone by and the sites are nowhere to be found in Google's SERPs. On the other hand, it took Bing, Yahoo, DDG about 1 week on the dot to produce the page 1 SERP.
I know there's been talk about caching all over the boards, but has anyone experienced any different treatment of new websites post Panda & other recent updates?
