I never thought I would write a review on a link shortening service but I had to after using Piar.io and Switchy.
What I realy like about B.link is the quality of the statistic provided when someone follows a link, I also like the support they provide when you can't find the information in the FAQ.
When you send text messages, tracking can be difficult but with b.link you can add some string in the url and they keep the information from a shortened link to the desination. Non of the other competitor offer this important option. It means that you can record some informations in a database coming from someone who just clicked on a shorten link.
You can now know if someone click on this link : https://b.link/nice?var1=abc&cel=1326548754 that the person with the cel number 1326548754 likes abc but also you can know anything depending on the var you add in the destination link https://desinationlink.com/marketing/smscold/file.php?gender=f&age=28&country=us&var1=abc&cel=1326548754
Here we know that the gender is female, age, country and it can be anything for future analyses. It can be linked to behaviour...

The only thing that b.link could offer is giving the possiblity to change text and picture attached to a shortened link.

If I could, I would buy some extra codes
