Many sites that previously had only their home page in the Yahoo index now appear to have multiple pages in the updated Yahoo database. I have not compared any of our "baseline" sites against any new sites that have shown up in the top 10 for various SERP's, but some SEO's are concluding that Yahoo has gone back to placing a heavier weight with on-page optimization.
Our client sites all remained stable with their top 5 SERP's for major KW's. My company site did show considerable improvement for some of our major KW's:
1. real estate internet marketing - increased 15 spots to #1 out of 62,500,000.
2. real estate web marketing - increased 21 spots to #3 out of 43,700,000
3. real estate web design - dropped 9 spots from #5 to #14 out of 45,700,000
4. real estate web site - previously not listed in top 100, now #10 out of 160,000,000
5. real estate marketing - previously not in the top 100, now #8 out of 42,500,000
My should be a decent baseline for me to draw a few comparisons of the old algo and new algo because for the past 3 months I have not added any links, added new pages, or made any changes to any existing pages. If I get some free time in the next few weeks I will run some KW/single page density and KW/total site density analysis and post the results here.
Of course, there are many other variables that may account for the change in SERP's, but this is a good place to start.
Just saw this on the Yahoo blog:

Third Weather Report: Yahoo! Launched New Search Index Last Night
We made changes to the index last night so you should be seeing more of your pages in the index as well as some fluctuations in the rankings of results from previous searches. The changes will be a little more intense than the second weather report and changes will continue over the next week or two.
