I've started recently a few campaings on this website. I received more than 20.000 unique visitors but only 1% procent made account on my websites. Is this normal? or the traffic from this referral is not good quality?
I don't beleive that adf.ly gives targeted traffic and that is the biggest reason no one is making an account on your website. I suggest you use Google Adwords as they will give you more targeted traffic which most likely will convert.
URL short sites are horrible to advertise on. People just use them to shorten long urls, not to enrich someone else. Waste of time and money.
A good way for people to earn a little extra cash. However, I don't have an account with them and I always avoid clicking on the links.
Personally I dislike clicking adf.ly links. Most of the people who have a bit of knowledge advice first where a link is pointing to, and if the notice it's an Adf.ly shortened URL, they try to avoid it. You have gotten 20.000 visitors, but as stated above, their not targeted. For self steem purposes you can keep your campaing with them, as they drive traffic to your site, but if you want targeted traffic, you need to change strategies. Try PPC with Google Adsense or 7search or any other PPC network you like. Also you can try getting traffic from Y! Answers (I recommend you to be at least level 2 before trying to post links, or they'll ban you). Cheers.
adf.ly isn't worth it. I personally avoid clicking on adf.ly links and instead search for alternatives. Why would I wait for a few seconds before being allowed to continue to a link when I can find other links via Google? From the advertiser's POV, you need a targeted solution that sends people that would be interested in your website. People browsing adf.ly links could care less about your website - they just want to get to their final destination.
