I seem to remember that the Yahoo SERPs were changing on an almost daily basis until very recently. No matter what changes I make to my site, Yahoo still returns it in the same position. In fact, the same 10 sites have been in the same 10 positions for over a week now. Moreover, all the cache results are at least 7-10 days old. What's going on? ... have they given up?
It does seem to hardly change. I am sure if you made a major change to your page like changing the topic of the page, you might see a shift. But then again it is Yahoo and they seem to be light years behind Google.
Tried that - more than a week ago. New Title and Meta description. Cached by MSN and Google, but still not showing on Yahoo. Grrr.
They usually only make major changes every few months. You'll know because they'll post a "weather report" here: http://www.ysearchblog.com/ They did an update in mid-December, one about a month before that, and the time between updates before that was 2-3 months. They seem to allow changes to minor keywords (3-4 word phrases, etc.) sometimes more frequently than that, but I haven't seen a jump in position on a big phrase except for during updates (the caveat: there are multiple datacenters. So yes, it bounces around in the keyword tracker, but always between 3-4 different set positions - i.e. 10, 25, 30, 40, just because you're ranked that on whatever datacenter you happen to pull up that day).
and another thing: why is it that although my site is displayed at #7 for 'London Escort Agency' ... when you click on the cache it states: -I've had a 301 redirect from that domain for months, so why is Yahoo still caching the old and not the new?
Now that is a coincidence ... Yahoo has just updated and given me 6 number #1 spots out of 12 keywords. Extraordinary.
I ranked well in Google and MSN, but not even in Top 10 for Yahoo....anyone having the same problem like me?
Looks like I spoke too soon. As I was tired of Yahoo returning pages that are MONTHS out of date, yesterday I deleted the entire domain that I had a .301 redirect on. This morning, most of my KW's that were in the top ten are not in the top 1000 ... Looks like I'll just have to wait until Y can be bothered to spider the site and give me back my old SERPs!
My results improved considerably when I added my site to the yahoo directory ($299/year I think). Before that the results were way behind on yahoo compared to google and msn.
