Web site consistency remains on an even keel

Web site consistency stayed even among big web retailers in October with 22 merchants achieving a consistency rating of “excellent,” according to Gomez Inc.

IRCE 2008 Conference Multi-Media CD-ROM

In October, 18 retailers received a rating of “good,” eight 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.

In October, the top 50 retail web sites had an average site availability rate of 98.54% and an overall consistency average of “good.”

Consistency Rating A qualitative representation of consistency ratings that are created with the lowest total score (Consistency + Availability) being normalized to 100. Above 98 = Excellent, above 95 = Good, above 85 = Fair, and below 85 = Poor. Consistency is the range between the high and low values of one standard deviation from response time. Availability is determined by the percentage of tests that fail to correctly load. Copyright© 2007 Gomez, Inc.
