This test determines if your page make use of image maps. While image maps are a convenient development shortcut, they are not considered mobile friendly. The additional weight of embedding links in images increases transfer time and rendering speeds. Additionally many mobile devices do not provide ample means to use image maps to users.
Checking for image maps
This test checks to see if the page markup uses the “usemap” syntax to reference an imagemap. If any image maps are found then the test reports a FAIL.
If you receive a FAIL for this test, you should consider redesigning your links to avoid using image maps.
This test is based on a W3C mobileOK best practice. See http://www.w3.org/TR/mobile-bp/ for more details.
