I have been using ZenCart for years and Google has always indexed my product pages with no problem and no real seo efforts on my part, but for some reason now NONE of my product pages or category pages are showing up when I search Google with "site:discountprintingservice.com"...I have been using DPU on my site for a long time but I have to ask can DPU interfere with Google indexing my pages? Or has the code of ZenCart changed with v1.5.1 that would cause Google not to index these pages??? And before any one replies "you need meta tags" I know all about using the Meta Tags and what good titles, keywords, & descriptions are and yes some of my products have them and some don't but previously all pages were getting indexed regardless of whether I defined meta tags or not....
