Why do Aol results differ from Google?

I'm #9 on Google and #15 on AOL's serps

If Aol is using Google results then why would my ranking be better on Google than on Aol? I'm #9 on Google and #15 on AOL's serps.

I did notice a momentary drop to #15 on Google a couple of days ago and then a quick recovery back to #9. Does Google get fed the results at some particular time and then continue to use the results until some new feed? If so how often does it update?

Any thoughts are appreciated.

It has do with the way AOL lists its sites. For instance- Google will sometimes list www.mydomain.com and then also under that listing, display an internal page; www.mydomain.com/subpage also known as known as clustering.

The other reason may be that AOL has its own content listed in the results. Any which way the results usually only vary slightly.

Actually your explanation doesn't jib with what I'm seeing. I happen to have two sites competing for the same three-word key phrase "Burmuda blue widgets." One site has info on the north of "burmuda" and the other on the south side of "burmuda."

One site is listed #9 on Google and the other is listed #10 out of about 80K results. (These are separate sites - not different pages from the same site).

On Aol, the #10 site retains its position, but the number #9 site drops to #15.
