Yahoo's Index Size

[ggrot]

Did you guys see this?
[businessweek.com...]

In a major expansion, Yahoo Inc. said Monday that its online search engine index now spans more than 20 billion Web documents and images, nearly double the material scanned by rival Google Inc.

Yahoo's expansion doesn't necessarily mean it produces more useful results than Google, which has long been considered the Internet's most comprehensive database.

...

Until Monday, Yahoo hadn't publicly disclosed the size of its search index, but industry estimates had placed the figure somewhere between 6 billion and 8 billion.

Looks like yahoo is claiming a larger index than google!
Have you all noticed any extra spidering or search results recently?

Yahoo serps are probably better than Google's, I think we may just be used to Google and that's it. Also I apreciate the fact that Google is lighthing fast showing serps, a lot faster than yahoo actually. I think that's the only reason I use Google over Yahoo.

In any case GOOGLE WON'T STAND THE KING FOR TOO LONG. History repeats itself over and over and this time it won't be differnt. I don't need to mention prior engines that were KING before as you all know them. Yahoo is working very hard on their search engine, remember the last Yahoo update, It did improve results a lot. I see Yahoo focusing a lot on it's search engines business latetelly. Think YPN, they know were the money is, so now they are investing their time and efforts on search the engine. No more directories, hosting, news, or yahooligans. It's Yahoo time for search engines.

I'm not surprised Yahoo's index is larger.

vbulletin uses cron.php to do some cronstuff, and uses that to load an image on every page a user visits.
To make sure it is requested everytime they add an unique number as a parameter, so the uri becomes: /cron.php?rand=236423

To no suprise yahoo lists a huge amount of these when I do a site: search.
I bet they count those as well!

Google will indeed get some heavy competition, but they are still definatly #1 when it comes to other languages for global search engine's.
both Yahoo! and msn are terrible for dutch search results at the moment. (so are the local search engine's).

Does yahoo's "expansion" include lots of newly indexed sites? And, if it does, does yahoo still give a rank boost to new sites like it has done in the past? And, if there is a new site rank boost factor, how will that affect the established sites? It seems that this creates a lot more competition with an advantage for the new sites. Has anyone noticed traffic dropping from their established sites as a result of the "expansion"?
