Know-How Exchange : Research/Metrics

Try Foresee Results. https://www.foreseeresults.com/ I'm not sure if their method prescribes at what point during a visit the survey comes up, but I'd think they'd work with you to satisfy your reasonable preferences. I haven't had personal experience working with them, but know the company and their services are based on a respected academic analysis method of customer satisfaction.

My question is why are you looking to put your survey when the user is bouncing out? I'm curious.

Hi temafrank,

Some of the major online suppliers (e.g., Survey Monkey, Zoomerang) allow you to post a link on your site that directs people to a survey. It sounds like that might be your best bet. You can put a link on the page that they exit from, or they last view, if that's possible to know.

Good luck,
Joy

If you capture their email address, then email them an invitation to your survey.

You're right to worry about it being intrusive.

I've noticed that Microsoft and HP use something like this. Pretty sure they pop up after the second click within their site, though, rather than at the point of exit. I think at that point you've lost control of them (unless you're mousetrapping, which will upset Google).

Next time I see one pop up I'll make a note of any useful information about the service vendor.

You might also want to ask the same question at this techie forum:

Hope that helps.
