Either someone at Walmart has made a terrible mistake, or else the retailer's SEO trolling is top notch.
Jezebel points out this morning that Walmart's collection of Halloween costumes includes a "Fat Girl Costumes" category. We checked and found it was indeed live on the site, at least as of 10:30 a.m. today. (UPDATE: The category was purged of all items around 11:15 a.m. See below for details.)
There are several other "related' categories like "Plus Size Halloween Costumes" and "Adult Plus Halloween," which makes me wonder if these groupings are automatically generated from some of the descriptive metadata supplied by low-budget vendors.
If so, it might be time for Walmart to step up the curation on its site's organization.
