A few days ago I was searching for some freebies and found something I wanted to download. When I pressed "download" link I was unpleasantly surprised with the modal window which you can see in the image above. Why this was an unpleasant experience?
No explanation
First of all, I just wanted to download some freebies (graphics). I expected to be able to actually download the file when I pressed the download link. But I was prompted with this small webform and needed to think about it. What is the purpose of this form? Why I need to fill this information now? Not only they are disturbing me now, they also want to disturb me in the future? There was no explanation on why I need to fill this information.
No option
I wondered was there an option, on the previous screen, for choosing whether I want to be contacted by this website in the future. Maybe I missed something? I would understand the need for leaving my email address if this was a software. They could then send me some activation code or serial number to my email. But still, it would be nice to see at least one sentence on why my email is required.
Phone number?
On the top of everything, I saw that phone number is mandatory field. That was weird. Not only I needed to leave my email just for this one download, but I was also needed to leave my phone number? Why this particular information is important for the action I wanted to perform? Would they really call me with some promotional offers? There just wasn't any logical explanation.
They break one of the most important rules of web usability: "Don't make me think". They made me think. And I left the site.
Conclusion
This was just one small example how poorly designed web form can force users to leave. I think this webform shouldn't be there. At least some kind of explanation would be needed as well as option to choose whether I want to be contacted or not. And, of course, phone number shouldn't be mandatory, if it should be there at all.
How do you react in similar cases?
