Jeffrey Davis recently reported a 30%- 40% drop in his site’s referral traffic from StumbleUpon. There’s absolutely no doubt that SU is one of the most potential sources for getting a good amount of referral traffic. In fact, many blogs receive as much as 60%-80% of their overall traffic from SU.

After SU rolled out their redesign last year, users felt quite happy to know that the site was paying some careful attention to its on-topic features. But, as soon as, SU bid adieu to direct links recently, everyone was taken aback. Earlier, you could easily ‘x’ out a page and visit the original URL from inside the site. Now, while logged in, you can’t get out so easily.

There’s one way, though somewhat clumsy. If you want to visit the original source, you need to copy-paste the URL above, while leaving the SU part of the URL out.

Here’s what the URL looks like.

Well, SU is trying to confine users within its own eco-system. Funny, isn’t it?

On the other hand, Pinterest (a visual bookmarking site) is attracting eyeballs from many sides. Though it’s a new entrant in the social arena, it’s fast turning into a potential sources of traffic for a wide range of businesses. According to a recent report by Shareaholic, Pinterest is now rivaling Twitter in terms of driving referral traffic to a website or blog.

What’s more, Pinterest is generating more referral traffic than its elder social brothers like Google+, LinkedIn and Youtube are doing together. Though a lot of businesses are still quite unaware of the traffic opportunities that a social bookmarking site as young as Pinterest can bring, others are flocking to this Pinboard in large numbers.

Though Facebook still rules when it comes to driving referral traffic, Pinterest is fast picking up steam. The growth of this visual pinboard has been phenomenal over the last couple of months. Shareaholic recent findings (after analyzing data from as many as 200,000 publishers) reveal that Pinterest drove around 3.6% referral traffic in January this year, shooting up from merely 17% in July and 2.5% December last year.

Many have been reported to ditch SU as well.
