Mobile search differs in many ways to desktop search. The location where the mobile user is when searching has implications on how you design your mobile site, such as home, work, commuting, in store, bar/coffee shop, or other, try to determine what they are looking for and have that readily available.
Mobile is also where users search for local information, make sure you are registered with Google Places, Bing Places, Yahoo Local and other local search engines Make sure that the nature of the business, location/business area, address, contact details, opening hours, availability (of stock, tables, rooms etc), what’s on (at your business and nearby), news, menu (for restaurants) and so on are up-to-date and prominently displayed on your site, so both visitors and search engines can easily find them.
Use the device capabilities or lack of them. This allows you to utilize the likes of click to call, click-to-download, use mobile coupons, voucher codes, offers and competitions to attribute email, advertising and SMS campaigns to mobile sales.
Use QR codes, Bluetooth and near-field-communication (NFC) with dedicated mobile landing pages to help track the impact of off-line campaigns. these are just some of the differences from desktop to take into consideration when developing your site.
A couple of stats: “25 % of overall search queries are now on mobile devices.” – BIA/Kelsey (April 2014). “During the 2014 Winter Olympic Games, 60-65 percent of Olympics-related searches were performed on a smartphone or tablet.” – Google (April 2014).
