Will changing the ads on my site affect my SERPs?

Hello. First of all I would like to apologize is I posted this threat in the wrong section. I have a question that really kills me for the last few weeks.

Will changing the add company on my site affect my serps?
Are there any logical explanation. I saw that after changing the ads on one of my sites the serps felt by 1 position. I know that this is only a site and not tested more but I would like to know if there are other members here that experienced the same thing.
I have a high traffic site that I would like to make some changes but I`m afraid that I will lose the traffic from Google since 90% of my traffic is from there.
I look forward to your answers.

The only thing I've ever heard of that is relevant was in a Google patent several years ago. It said that the quality of advertisers on a website "may be" used as one measure of a website's trust and authority.

In practice, I've never noticed or heard of such an issue.

I think that if that was true , could start a frenzy in blocking advertiser from the list. As for changing the ads... I still do not what to say. I have an add company that has not payed me for over 3 mouths but I`m afraid to change it so my serps will fall. I`m still have with what the other add company brings as revenue . But still , to keep an add firm and send visits to them for nothing.

I switched from all Adsense for the longest time (4 + years) back in June to a small (my niche focused) ad company. That is right around the time my Google referral traffic dropped a constant 40%. Only a little recovery since.

Only problem was that this was also right around the time of Panda 2.2. Mine traffic dropped June 18. Panda 2.2 hit on June 16. I'm not sure there was an official date on Panda 2.2 anywhere.

I'm in the process of switching my ads over to google ad manager to serve the same network ads + adsense. Hopefully that will help too.

Ohhh I think I will try to test some more. One other sites of mine. That is the only chance to find the right answer. I also saw a threat on google webmasters forum with a guy saying that he changed the ads on a whole network and his rankings dropped to death. "Nowhere to be found" that is what he said. I do not want to mislead people. I just want to make it clear in my head.

Warning: if you replace ads such as adsense with links to affiliate offers your pages will become considered affiliate in nature and too many of those on a site will cost you traffic SITEWIDE (not just on the pages with the ads).

I don't know what the thresholds are for number of affiliate offers or number of pages with even one offer but when you cross it your site will take a sitewide traffic loss, to all pages. Just an fyi - I've both seen this on other sites and tested it on my sites.

I do not know if another add company is considered an affiliate link. I want to use adsense together with another add company. And the thing that worries me is if I change the other add company that doesn`t pay me will go down in rankings.
I have one more thing to ask. Is changing the add code considered a change in layout.
