Data

In order to group data into proportional slices and bars we rounded host ratings with a php function. See http://php.net/manual/en/function.round.php for details.

 echo round(3.4);   // 3 
 echo round(3.5);   // 4 
 echo round(3.6);   // 4 

Interpretation

Not all web hosts equal. Trust me, we've been looking into this issue for a long time. Some of them lack reliable customer support, yet have 5-star ratings accross many review sites on the web.

These are just some of our general observations when it comes to ratings distribution:

• Affiliate websites, built for the sole purpose of generating income through affiliate traffic, have most of their reviews within 4 to 5-star range. All of their promoted products are glittering and dazzling.
• Open directories have a left-skewed (negative) distribution, where the mass of reviews is concentrated on the right of the figure. The reason for this is the overwhelming ammount of 5-star ratings. To gain visibility, small and unnoticeable companies usually ask their customers for positive feedback, while at the same time there is no one to complain.
• On the other hand, right-skewed (positive) have nothing but customer complains.

Go with a review site that has a symetrical bell-shaped ratings distribution curve. Most likely, their ratings are based on both positive and negative reviews. Once again, if the shape of the distribution resembles a bell curve, the feedback data is likely real. Learn more about normal data distribution here.

This table consists of all hosting provider ratings we were able to find at the reviewer's website, along with the calculated number of hosted domains and global ratings.

We believe with this information, it is much easier to understand how a web host performs on a global scale and to avoid making a biased decision.
