Apparantely i read a rumor on yahoo siteexplorer forums that mentions as follows: Site using google adsense are been penalized by Yahoo and are not getting indexed well in Yahoo SERPs. Read the following post, it is posted by people like you and me and not officially by Yahoo! http://messages.next.yahoo.com/next/threadview?bn=SEA-YahooSiteExplorer&tid=662&mid=669 Its not one or two of them, there are actually plenty of people complaining on that forum. So believe it or not, yahoo does not like people using Google adsense.
I bet there are a lot more examples where that isn't true. I haven't found that to be the case. It wouldn't even be in their interest to do so because there would be so many sites that they would have to penalize that their search results would become less relevant and then people wouldn't use Yahoo search as much.
I don't think Yahhoo is in a position to start a ban war with Google. They will only likely loose more revenue.
I would happily trade my adsense in for ypn. google's a cheap bastard. But yes... I agree... I don't think yahoo is going to compromise their search results quality just to weed out sites using adsense. Yahoo needs to kick ypn into full force damnit.
This is bull shit Yahoo doesnt have anything to do with what ads you display on your site. Majority of big sites use adsense and rank very well on yahoo.
I would suspect it is sites that are heavy on google adsense ads and very low on original content that are being penalized. It would be rational to assume that yahoo put in a 'google-adsense-spam-filter' where it would get triggered by most auto generated content sites that are filled with adsense and very little, if any, original content. Other than that - it could be a sitewide change to the structure of the sites that are affected that has diluted their content and made it less relevant to yahoo searchers. (I mean having a lot of ads in general placed before content could dilute the relevancy of the page due to the way webpages are read by spiders).
I don't think Yahoo would be targetting Google ads at all. There are lots of other ad programs out there similar to adsense so why should they pick on adsense. Adsense is written in javascript too and the SEs aren't very good at reading javascript and may not execute javascript at all so it shouldn't dilute the content and especially not the relevancy since adsense is a context-based ad program.
Good point. But if they were looking for adsense, they could easily recognize the adsense code. Like everyone else is saying... I don't think this is anything to worry about. I use adsense and my pages are in yahoo search and yahoo local.
I wouldn't call this BS too quickly... stranger things have happened in business. Anyway... I have thought something similar myself. I have a handful of sites that have always ranked very well on yahoo. First page and often number one. Well... a few weeks ago I was checking SERPS and the only pages that ranked were pages that had no adsense on them... like contact page and privacy page. Sure maybe there is another explanation.. but that's the first thing that came to my mind.
Yep. My sentiments exactly, except I would just write MFA for short. I have quite a few sites that are getting clobbered in the Y! SERP's by competitor sites with AS ads, usually because their content is better or more expansive than mine.
I don't think that is the case, but I do know from experience that yahoo doesn't like sites which have too many affiliate links.
I suspect this one as well. When we started to implement adsense in our site our sites rankings and index pages dropped. Just my suspicion though
I can confirm that every single one of my high traffic sites (which coincidentally run Adsense) are virtually banned in Yahoo. I've submitted reinclusion requests - only to start showing back up then getting dropped again. These sites get very strong Google and MSN referrals (one over 200k per month), yet just 800 from Yahoo. Coincidentally, I have several sites that get good traffic from Yahoo. These are smaller sites or sites that weren't built for revenue. These sites do not run adsense. All these sites were built by me, hosted on the same class C block, promoted the same, built links by similar methods. You be the judge, so many reasons point to the possibility Yahoo is snubbing sites displaying Adsense (maybe to steer traffic towards sites showing their code?). Who knows. There may be other reasons, I'm sure a bunch of folks get good Y! referrals and show Adsense so...
It wouldn't surprise me at all if this is really the case. I just thought I sucked at Yahoo optimisation. Maybe not. LOL So what about sites with YPN then, how are they doing?
Drops in serps happen accross the se board as things change. when we get drops in goog serps, we don't blame yahoo ads do we? I would imaging that they could be looking for overly excessive ad/affiliate stuff, I would... but who knows.
That is what I meant, not just google adsense - but ads in general (ads or affiliate links / content ratio) ... the old saying, less is more is true in that sense and would appear to improve quality if it wasn't diluted with a tonne of ads. However, there are always exceptions and it is speculative to assume that adsense is specifically responsible - there could be an unknown amount of variables that were evaluated and the algorithm updated etc.
I have had adsense on my site for over 12 months and in this time I have been in the number one position on Yahoo for all of this time! Do a search for diy help on yahoo and see for youself.
I don't know, but I have noticed that when I have optmized client sites they sometimes rank in yahoo for years but when I make my own sites that acutally have more original content on them then the client sites, but have adsense and afiiliate links they tend to only rank for a few months
