Web site consistency improved slightly among major web retailers in April with 17 merchants achieving a consistency rating of “excellent,” according to Gomez Inc. The top 50 retail web sites had an average site availability rate of 98.40%.
In April, 24 retailers received a rating of “good,” six got “fair” and three received “poor.”
The consistency ratings take into account differences in the speed of web page delivery across multiple visits and the frequency a retail site is unavailable because of downtime. The variability of response time and the number of minutes out are combined to create each retailer’s consistency rating, Gomez explains.
