Does anyone have any tips for ways to reduce irrelevant ad clicks from people with low intent? I generate leads for a company that is primarily interested in business email addresses... if our ratio of gmail,yahoo,hotmail email addresses to work email addresses gets too high they interpret that as a quality issue.
One of the things I've been doing is adding text to our ads that states "business email required" - and I've also changed the form field label from 'email address' to 'business email address'. I'm a bit surprised to find that we still see a lot of gmail/yahoo/hotmail. Any tips or ideas for weeding out users with low intent (both in the ad copy & on the landing page) - or ideas for helping increase the "business email to free webmail email ratio"?
For the record, about 80% of the leads we are generating here are via Facebook.
Why don't you add a script that rejects free email addresses like yahoo, gmail?
You can change the place holder from "business email address" to "email@yourcompany.com" should be clearer.
Also, more drastic, you could block hotmail/gmail/yahoo, showing an error like "only company emails allowed" or something like that, you'd need to do the maths and see if that would be a profitable solution, consider asking for a bump too to compensate that loss.

Rejecting those addresses is a pretty strong step and will impact the CVR greatly and I'm afraid it could kill the profitability. If I understand it right, they will take even those emails but they want them to be a low %. Try to work on your copy, tell the users that gmail/yahoo/hotmail isn't really working for this (problems with delivery/low limits), tell them how it's a serious offer and you are looking for legit users "because the past experience wasnt good with free email accounts" ... try to make it part of your angle - since this is a special offer, it's not for everyone, especially not for kids with anonymous gmail accounts ... something along these lines 
I worked with a client in B2B space that had the same issue with free email accounts. They used an API(I don't remember the name) that rejects all the fake, temporary and free email addresses. They saved a lot of money because 90% of all free email accounts were from time-wasters who didn't buy anything, they just wasted hours for the sales team.
Normally, if it's a good quality lead, he/she will put another email if asked.
Now if you don't care too much about the lead quality(like you are not getting paid for end-conversion), you can put a cap on free accounts/day or month.
