The largest web retailers delivered a mixed web site performance in November, says Gomez Inc. 11 retailers achieved a consistency rating of excellent in October, compared to 15 with “good,” 17 with “fair” and 8 with “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 November the top 50 retail web sites had an average site availability rate of 96.71%.
Web retailers and industry analysts are keeping a close eye on web performance in November and December in the wake of record holiday traffic. Already a number of major sites, including Amazon.com, Walmart.com, Overstock.com and Macys.com, have incurred slowdowns and some outages.
