Hi all, I am considering using full overlays/modals for an e-commerce site for all our product pages (category/listing pages will be "normal", the product page will come over the listing page as an overlay/modal when you click on the product). Those “product overlays” will also be accessible directly with own URL (if need to be linked to for ex.). All the literature I find out there treats overlays and modals as “marketing” ones (ads, sign-ups, etc.) and is generally critical to overlays when it comes to SEO, while also saying that an overlay that has to do with good UX should not hurt the SEO of our site. What do you think? Will all product pages as overlays be considered as good UX by the search engines and therefore not be negatively impacted, SEO speaking? Or should we stay clear of overlays and create “normal” product pages? Thanks in advance! Arnaud NB: The reason we want to create those overlays are for design and UX purposes, and try to increase our conversion rate.
