Preventing spam submissions


We have some landing pages that I’m pretty sure are being filled in by bots.

The names used are typically foreign, and don’t have LinkedIn profiles (b2b landing pages).

The email addresses used are mainly Yahoo/Gmail or domains that don’t have websites on them.

The phone numbers used are often too long or too short.

How are people getting round this? Our landing pages only get PPC traffic and the URLs have not been published elsewhere.

I can’t seem to find a way of installing a captcha on Unbounce?
