Alexa.com is a great site to use to monitor how much traffic sites get. I noticed recently that Teltel, a company I have written about before in an entry titled: Teltel A Skype Killer? had a huge drop in web traffic from a 3-month average of around 10,000 to a one-day average of 31,381. I didn’t have a chance to ask the company the reason and to be honest it could even be a problem with Alexa causing this drop. Who knows? What I did do was to compare their traffic to Vonage, Skype and Packet8.
One thing I should mention is that service providers who direct callers to their site when taking or making calls will have higher Alexa rankings as they get more traffic. Here is the link to Alexa so you can try it for yourself.
Here are the rankings (Lower numbers mean they are closest to the top site in the world).
Here is the actual growth chart below:
I am not aware of any problems with Teltel that would cause the drop but thought it was worth this information.
