Yes, I have been watching it for a while (probably going on since Thursday last week) - Yahoo seems to lose pages and then add them back in again at update/shift time.
EG. During the change - the site page count can drop by a half or more - but by the end it tends to settle back down again (or even increase)
Well that happened for the last two or three shifts/updates anyway. (Well since the beginning of the year I think.) So for people who do a site check and see a lot less pages - dont panic yet - wait it out first ;)
Each day it also seems like more pages are added.
Actually I am seeing something really weird: it's like there is a new penalty being applied and some sites are just disappearing while leaving the bulk of other sites in place.
Or is that just the SERPs that I'm watching?
Either way, very frightening, I had totally reordered the url structure on two sites and they disappeared from yahoo (it's normal) but they are not coming bcak this update it seems.

Tried a search on site:www.webmasterworld.com and it is showing for me less than 200,000 - over the last few days this has been over 300,000 - at about 250,000 and anywhere in between the lowest and the highest.
Yahoo consider link exchanges as link farms. Link exchanges can result in penalization in Yahoo - that was news to me about link exchanges.
Wish it would settle down soon (at the higher number of course)
Site search for WebmasterWorld is now down to 169,000 for me - what have Yahoo done with all the pages they indexed?
I said earlier that pages tend to return - but this has been going on for a week or so now.
Unless people think a site search on Y is no good?
However, I am seeing less referrals from less pages.
Hmmmz - personally I think Yahoo are operating on a reduced index and they do this at index update time - but this one does seem to be dragging along.
I'm flip flopping from about 320 pages (50 in cache) to around 500 pages (200 in cache). These appear to rotate several times a day (at least that I notice).
I also know that the overall number keeps increasing daily for both versions (in terms of pages indexed and in cache).
Yep - could be monthly update at Yahoo though:-
[webmasterworld.com...] - June 20th
[webmasterworld.com...] - July 20th
[webmasterworld.com...] - August 22nd (although not to many comments on this one)
[webmasterworld.com...] - Sept 21st.
and this one - October 25th (ish) - I think maybe last Thursday
And BillyS and Dayo_UK, you're both mentioning page counts, but I still haven't seen the SERPs shuffle a lot (just the potential new filter I mentioned sinking some sites).
Not sure about the filter - dont know enough sites who use Digitalpoint and never heard of link-vault.
As for moving serps - I dont normally track individual serps - but for page counts just do a site search for site:webmasterworld.com and then do another one a few minutes later.
Jumping all around the place.
In my neck of the woods zero movement of SERPs.
Not really talking about serp movement - more number of pages indexed.
Yes, fine if I search on my main keywords - all looks as it should be - but less pages does seem to be less referrals as far as I am concerned (Lol sounds obvious - but just underlining that I dont think it is the site search being iffy - but pages missing)
A bit frustrating to say the least.
Perhaps it is just the site search that is pants then :)
Funny thing about the site: tool with Yahoo (at least for me) is that for every ten results (1 page) you advance the number of total pages drops...
Can't see a chance in SERPs though but maybe it is just some internal pages (as per your page count theory).

Started running into that on Yahoo. Last time was when they last updated.
CF
It looks to me like either pages lost from the index or internal pages now showing the homepage.
Billys,
Are you seeing the same thing?
The number of pages that I have in Yahoo's index changes almost four or more times a day. They are definately rotating at least two sets of results because I've got about twice as many pages in one set compared to the other.
What I see is that results are different depending on the localization.
If you doi a search in Europe you have a different algo ( the old Algo ).
Despite that, the database is fresh, only the Algo is old.
If a log on Yahoo.com using anonymizer.com, I got the new algo. The new Algo seems to me similar to search.msn.com: it privilege big sites with a good network of interlinked sites....
