This is a very common question. Templates (when done correctly) do not affect the mobile experience. Most purchases from mobile come from ipad's or tablets which offer buyer a full web browsing experience. Other purchases done from mobile phones have the templates automatically stripped out by eBay. So templates are still a great way to separate you from the pack. There are a few tips that you should follow when building a template, and that is to build a template that is not too wide and use mostly new CSS standards. Luckily, when you use inkFrog's template builder or prebuilt templates, everything is done for you. Our templates are mobile optimized and just work!
