How to remove all product pages meta descriptions and keywords, please? Only keep the title tags. Remove:
<meta name="description" content="" /> <meta name="keywords" content="" />
Edit the “customer/meta.tpl” that is used by your theme.
For example, if your theme is “light_responsive”, the file is “skin/light_responsive/customer/meta.tpl”.
Another file that may be used on your site is this one: “skin/common_files/customer/meta.tpl”
