Some retailers launched online deals well in advance of Thanksgiving, Black Friday and Cyber Monday.
The chain retailer led both Internet Explorer and Firefox tests.
Macy’s placed first among large retailers in December availability tests, says Compuware Gomez. Last month, the retailer posted an availability score of 100% for Internet Explorer and Firefox browser tests.
Three sites—JCPenney.com, OfficeMax.com and Williams-Sonoma.com—tied for second in Internet Explorer tests with a score of 99.99% availability. HSN.com and LLBean.com were next, tied at 99.98%.
In Firefox testing three retailers, Dell.com, HPShopping.com and VictoriasSecret.com, tied for second place with a 99.99% availability rating. JCPenney.com and Overstock.com followed, tied at 99.98%.
The average Internet Explorer availability for the 22 retailers measured in December was 99.88%, according to the Compuware Gomez Benchmarks study. The average Firefox availability for the same group of retailers last month was 99.92%.
