Do pop-unders affect ranking?

[seoservices500]

I want to know more bout this... Very Nice!

[familybizguy]

I was page rank 4 and then added a popup/lightbox and my pagerank dropped down to pagerank 1 after about a week. Has anyone else experienced this?

Thanks for clearing that up Matt, as its been a misconnection amongst many people, who have been arguing their cases from both sides, for many years.

(Matt, Google His Hair Clinic, it may be just what your looking for without knowing it)

i don't like pop under sites

[vxcriss]

Personally I find pop-unders much more annoying than pop-ups since they just "hide" there and sometimes they pile up in the background, and then you end up wondering where the hell did all those pages come from. It's like a poor attempt of hiding that you're an annoying site.

Case study - I had added cpalead to my most visited "-download.html" page for a month, then it suddenly drops from google on all keywords from rankings. 4 Weeks passed, I removed the code from the page and submitted the site map, and ofc it was back from 1 (with site links) to 3 position.

So telling us "to best of my knowledge" 2x doesn't explain why in the hell an individual page in my case that had javascript pop up code would be dropping in and out.

+1 to the request, hopefully this will force some of the large websites to stop serving those annoying popup ads, but then again I never see them thanks to my browser :D

You often say in your answers that you are not familiar with everyone and every factors in search quality.

It would be cool if we could sometime have the point of view of someone else working at Google that might have better knowledge about some specific topic.

It's not that we don't like you Matt of course ;)

@quebecclimber you got a good point. "to my best acknowledge" is not the most precise answer, so as you say it would be cool if someone that does know would answer to.

[MattCutts]

@quebecclimber Fair point. So far I haven't found too many other quality engineers who are really excited about stepping in front of the camera for questions at this level of detail.

@MattCutts - Matt, beggars can't be choosy. I think you do an awesome job and I go to YouTube at least once a day solely to watch these videos. I'm a small business owner who wants to have some solid knowledge on SEO, SEM, etc. and these videos allow me to get that. Keep up the great work and thanks to the whole Google gang.

@quebecclimber on the subject of the search criteria, I honestly think that so many different things have been added to the algorithm that no one person can keep track of all of it; even if we lose our Matt, we wouldn't gain omniscience. X)
