I had bad experience using exit pop. However, I still find people still get ranked in SERP even with exit pop installed so just test and find out your result.

From my personal experience there is no negative effect on SEO rankings if using an Exit Pop

You don't take a hit from exit popups. They can only be triggered by an event fired from the browser. Crawlers don't get affected by them at all.

Search Engine don't read Exit popup. It only appear when some one close that window/tab so that doesn't take any effect on SEO of your website

SEO don not read exit pop-ups appear only when some one so close the window/tab that has no effect on doesn SEO of your Web site.

I do not believe it will effect your SEO ranking, it might effect the 'user experience' but that's about it

yeah exit pop hurts seo

I see lots of sites that rank and have exit pops on them. More importantly though, exit pops can really improve your conversion rate. I'm not sure if all of them do it, but the one I use drops the affiliate cookie on exit. It's kind of like a legitimate way to cookie stuff. A lot of sales can leak through since people don't buy right away.

I had a page that was getting like 500 uniques/day and promoting an Amazon product. Without the exit pop, it hardly made anything because the % of people who clicked through to Amazon was low. When I put the exit pop on that page, it instantly started making like $20/day because the exit pop was dropping 500 cookies/day.

Back to your original question though... I think it's possible it can affect SEO because exit pops are a crappy user experience. And we know user experience is what Google cares about.

That would also interest me.

I mean your experience with dropping cookies on exit is quite impressive, indexphp!
How long have you been doing this and didn't you have any problems with amazon?

If you do for a squeeze page or sales funnel i dont think you have to worry but if you do for a real site like a Blog or Company site then will hurt you.
