I don’t know how you spread all products out over pages, but when I go to your live website and do a quick network analysis; you send me over 180 requests, 45.5 MB in resources and a ton of images that I do not see on the page. (to compare: google maps, a pretty heavy web app, only bumps me 120 requests with about 5MB in resources)
I’m looking at a page that show me the categories + a single versa tire part and in my network request analysis I see a big load of images coming through that are nowhere visible on the page itself. I even see the paypal logo in there while that logo is nowhere seen on the page I’m on.
Why is all this stuff loading in the background?
