Anyone switched AdSense->YPN->AdSense and was penalized by Google?

...or vice versa

[John Carpenter]

Has anyone who switched his/her entire site from Google AdSense to YPN and then back to AdSense seen any kind of penalization by Google? Or vice versa (YPN->AdSense->YPN penalized by Yahoo)?

(I'm not saying we have, just asking in case we need to switch.)

We did AS -> YPN -> AS and did not notice any penalizations.

I alternated YPN and AS on a daily basis for several weeks (now 100% AS). No penalty observed.

When I first tested YPN on a few pages that previously ran adsense ads, I saw a huge tank in my adsense income that took months to recover.

No "scientific" tests were done, so it could be any number of earnings variation factors, so I can't say for certain that it was a "penalty".

Could be just a coincidence.

I switched 100% to YPN for 2 months. About 3 weeks ago I switched 1/2 of my pages (~70% of traffic) back to AS. Right now I am getting about half of what I was for those pages three months ago.

What do you mean by "penalization by Google"

In SERPS or EPC?

[ann]

The same thing happened to me as happened to Rodney and it still has not recovered fully.

Thanks for the responses.

What do you mean by "penalization by Google"

Well, I wrote "any kind of penalization", but actually I meant penalization in the form of reduced AdSense/YPN earnings or eCPM.

Nonetheless, SERPS penalty could be interesting to hear about too.

I did the round trip switch and noticed a little spotty performance for a couple of days but now I don't see much difference in G performance, in fact it may be a little better compared to last fall.

I tried the GeoIP targeting but performance of Y went way downhill and I felt bad serving only foreign visitors to G - and they may not have appreciated it either.

I'll periodically switch Y back on now that I have a method to do it in a minute.

serving only foreign visitors to G

That could have skewed the "performance history" that Google keeps for each ad/site. Visitors outside the US may click less on ads that are usually displayed on your site, so Google's algo flagged the ads as "not performing well (anymore)" for your site (because of the lack of US visitors, who might click them more), which may have led to "worse" ads being served when you switched back to AS.

[sailorjwd]

Luckily I only send foreign visitors to G for about 3 days - enough time to know this wasn't going to work. CPM has been getting a tiny bit better each day for the last week.

adsense epc tanked for me in the middle of december, for reasons unknown to me, so i switched the worst traffic i had over to ypn on the first of january.

so far ypn epc has been up and down, but lately it's paying a bit better; i get some great ads in my main sector, and some days ypn earnings even match the adsense earnings... the computing sector i'm also in, tho, has been a lousy match for ypn ads.

so ymmv, depending on the sector you are in... i use geoip for ypn, with the foreign traffic going to adsense, but that's only about 10-15% of my overall adsense traffic.

I've noticed on one of my sites that if I switch the high traffic pages (homepage mostly) back and forth from YPN to AS, overall I make more money. I switch about every 3-4 days. I suspect that this somehow resets things (at least in this particular niche) and I get the higher paying ads more often for a couple of days. I've seen it increase by as much as 80% with this tactic. For what it's worth.

That's interesting. Thanks.
