I'm trying to setup a directory which focus on mobile searchers. I'm very happy that GEOCraft is now responsive but have some questions. 1 - When they look up a business on a smartphone they should get a tap to call button on the mobile front page when they get a result. How this can be done? 2 - My directory would work nationwide. What would be a good link structure to feature businesses all over the US? mydirectory.com/category/subcategory/businessname Where category and subcategories can be zip codes, states (like ny, ca, sc etc.), or city names of course what would be the best in terms of SEO? 3 - Mobile sites should be as lightweight as possible. Is there a way to display LESS from the homepage when someone access the site using a mobile device? I guess not but it's good to ask. G.
