Anti AdSense Serps?

Could there be a manipulation at Yahoo's end?

[Sobriquet]

There has been an ongoing movement at yahoo serps, which is also discussed at [webmasterworld.com...] .

Now, at the same time, alot of adsensers seem to feel the heat of traffic loss, revenue loss or bad targetting.

Targetting is often done ( as i have seen ) on the basis of page content AND the referer ( and referer keyphrase.)

Is there a chance that yahoo results (in its new algo) are being somehow coded ( manipulated ) to give YPN publishers an edge over AdSense Publishers? or simply to chisel out adsense publishers?

My readings is based on my main keyphrases, when searched in yahoo, provides top ten sites in which NONE of them had adsense on it. Three (not the top) of them had YPN ads .

My major traffic (for adsense) was from yahoo and which is majorly down now, in a array of sites, in different topics. On the other hand, my sites without adsense ( my business sites ) in yahoo serps have not been affected majorly.

This might be a subtle way ( very legal ) to gain yahoo advntage for YPN as compared to AdSense Publishers.

Try experimenting with your keywords or keyphrases in yahoo search and post your findings. I guess, except for people who have very strong standing in yahoo serps, most of them would find that adsense publishers sites may not be featuring in top 10 of yahoo results.

what if u run both adsense and ypn? will u be in the middle? ;)

If the theory is true and that you're allowed to publish both networks on the same pages, then you'll lose traffic from both of them. :)

Not that it's necessarily incorrect, but I see 2 problems with this theory:

1. Google provides about 5X as much traffic to webmasters, and if they fought back in the same way, the YPN network would turn into a ghost town.

2. In the long run the integrity of both sites would be irreparably damaged. All Yahoo and Google have is the goodwill associated with their brand name; if that is besmirched, their value stands to drop by many billions of dollars.

I am doing more testing with a lot of general terms searching in yahoo and seeing how many out of top ten sites have adsense.

I would request you all to search for your own kephrases and terms and see the top ten sites in yahoo and post the results that how many of them had adsense on it.

My Top 3 key phrases ( unrelated to each other as they talk of different topics )

1) Blue Widgets :Sites with adsense on Y top ten: 0

2) Buy Widgets: Sites with adsense on Y top ten: 1 ( at number 8 )

3) Widgets News : Sites with adsense on Y top ten: 0

---------

The terms I used were very generic, not really a niche anymore coz everyone seems to be in it.

Also, BTW, if any of you has a top ranking site in yahoo with adsense, please reply after you see if it isstill there. I lost my top yahoo rankings in last 10 days. I hope some of you are retaining it.

My main site is still #1(internal page), #7(home page) and another of my sites is in #10 on yahoo both sites have adsense on them, always have since adsense started, no penalising for me.

I started with AdSense 5 June 2004.

One of my domains was created 2002 and at this time well developt.

Jannuary to May 2004
70352 visitors from search engines
1658 from Yahoo search
2.3%

May to September 2005
106518 visitors from search engines
1479 from Yahoo search
1,4%

I think this is within the normal development

By the way, I have once seen a script which supports your theory. It was intended to hide adsense code from the Yahoo's bot Slurp.

Try experimenting with your keywords or keyphrases in yahoo search and post your findings.

I'm doing better than ever in Yahoo for the search phrases that I watch, and I have AdSense ads on nearly every page. (My Yahoo referrals are up, too.)

IMHO, coincidences happen, and anecdotal evidence doesn't prove cause and effect.

[Sobriquet]

my point is not about yahoo referals alone.

I am talking abut top ten results for an average search term. Are we seeing sites in yahoo top ten for any geeral search term, with as many sites with adsense, as it used to be, before the yahoo update.

[wheelie34]

surely if EFV's referrals from Y are UP that means hes moved up the SERP's in Y

Theres a good few posts here now saying the opposite to your theory, pointless going round in circles

The point has been proven, having AdSense code on a page is NOT causing any problems for other publishers, the general consensus is NO Y is NOT penalising sites for it, if they were, why would it be only some?

[jetteroheller]

Just made a test with some search terms and where my pages are listed

German combined word singular
Google 1
Yahoo only 4 results, but not my site

German combined word plural
Google 4
Yahoo not in first 10

widget producer type
Google 1,2
Yahoo 1,2

widget price table
Google 5
Yahoo 6

producer type application
Google 1,2,5,6
Yahoo 2

producer type application more precise
Google 1,2
Yahoo 1,2,3

So I can find no evidence, that Yahoo does not like pages with AdSense

Prior to September I was receiving 3 visitors from Google for every 1 from Yahoo. This evened out during September - just about neck and neck. Last night I noticed that Yahoo was starting to send slightly more traffic than Google.

I have yet to try to find out why this changeover has happened and the actual cause(s) behind it. My guesses are that either Yahoo suddenly started to give better results or that folks have simply switched their SE preference.

Either way, I definitely do not think that AdSense has the slightest thing to do with it.
