Metatags
Meta tags encompassing your entire site can be added in the process of editing your Theme source code for when people or search engines visit your website. Most search engines will use the description for a summary in their search results. To create meta tags for your entire site, please add them to the <head> section of the default.html file.
Please note that the meta tag information added here will be site wide! To add meta tags specific to one of your pages, please set them in the Page Description field within its Page Settings.
