I recently moved half of my site to a new domain. The directory was sreplaced with a redirect to the new domain. Both Y and G have two pages indexed; the homepage, and one html page about three levels deep that is one of the 500 gallery pages. Until yesterday G had the two pages and Y! had the godaddy coming soon page. I can't figure why they would both have the same page unless they were sharing indexes. There are no outside links to this page.

I ran a series of controlled test pages recently.

I was adding 9-10 pages at a time, and did 4 different batches on different days.

Google and Yahoo both picked up exactly the same pages, on exactly the same day and ranked them in exactly the same order.

Other searches I do show different results.

What does it all mean?

I noticed this a few weeks back on a new site as well... that the number of indexed pages was always perfectly in step.

The site has thousands of pages, and the number indexed was growing as it was new, but whatever the number was, it was always the same.

I receive a couple of hundred visits a day from google and none ever from yahoo though - which is odd.

No, in my experience Google and Yahoo's behaviour in indexing new sites, at any rate, is very different. Google does it more or less logically, Yahoo is clueless.

One site under development has only one incoming link that goes to site.com/widgets/. The index page in that folder, and the three sub pages linked off it, were indexed fully by Google. The home page was indexed but as url only. Other pages were ignored. Seems to make sense.

Yahoo on the other hand came in before there was even that one incoming link and indexed a random selection of pages. It indexed site.com/widgets/more3.html but ignored site.com/widgets/ and site.com/.

I have seen a similar pattern on another newish site.

Well today Google has bumped me up to 77 pages. Yahoo to 59. Both have crawled the entire site about a week ago. Google's first listing is different from Yahoo. The next 8 are identical and in the same order. Google has the same pages indexed as Y plus an additional 18. This is with results for both searches set to 100.

I noticed a lot of "coincidence" several weeks ago. I haven't looked recently - too busy.

I had a similar experience with a new site.

It appears that if Yahoo cannot find any results, it will show Google results instead.

Hi,

how did you manage to be added to the yahoo! index. I am trying to get in with several domains since 2 months now and nothing happens. My sites have plenty of links, some from dmoz and google-dir.
Don't know why my domains are not added to their index. Not that they are only not showing up for my keywords, searching for "www.mydom.com" does not bring any results, so they are not in the index.

My experience was the same as the first three posters' in this thread. I had created a new site, and when I checked in Google (www.google.com/search?q=site%3Awww.mysite.com) and Yahoo (search.yahoo.com/search?p=site%3Awww.mysite.com), I got the same 7 pages found - with the same snippets.

Then I tried to search for a text that was unique for my page and again Google and Yahoo showed identical results. I knew from my Apache log that Yahoo-Slurp hadn't visited my site yet.

My conclusion (as I wrote) was that Yahoo displays Google results if there are no results in the Yahoo-database. This was 2-3 weeks ago.

Yep, I came to the same conclusion.

Greg,

To be listed in Y! all you need it one site in Y! that links to you.

I have had two sites with no links at all get listed or at least a few pages of them. I never submitted.

Go to Y! Search for something (or just hit search button). There is a submit your site link at the bottom. It requires registration. My domain was showing the Go Daddy 'Coming Soon' page long before I added any links to it. Do they monitor whois data?

Yes, I think Y! does monitor whois data .. for a couple of domains I did buy a while ago I did put nothing on them .. even parking .. but logs showed couple of hits, I quick research showed that the domain names were indexed in yahoo. I didn'n put any link from any page to those domains .. so I guess the only source was whois.

From Google's S-1 filing,
[sec.gov...]

Since June 2000, Yahoo has used, to varying degrees, our web search technology on its web site to provide web search services to its users. We have notified Yahoo of our election to terminate our agreement, effective July 2004.
