If you’re looking to inspire more trust with your users an SSL Certificate is always a good way to go. For example if you’re promoting auto loan leads and have a private label offer then you should have the form page be SSL protected. Both for security and improving your conversions. Up until now it’s been 50-100$ for a SSL certificate, so normally I’d roll out a site/campaign and then if it did decent I’d get an SSL certificate for it. Honestly it will increase you conversions.
Now you can get one for free with every domain purchase. Amazing!
My favorite domain registrar has been Namecheap.com for some time. They’re interface is amazing a quick as opposed to some of the other domain reg’s out there * cough godaddyd cough *. And now they’re offering free SSL certs so I’d suggest you go check them out if you’re not already a customer. Here’s the link for the offer ( not an affiliate link as I don’t think they have a program ).
Also you can add this nifty little badge to your page as well.
