A responsive design is a key to mobile first design approach. With increasing number of users transacting and browsing on small/smart devices, it is imperative for a website/web store to be optimized for increased goal conversion on smart phones and tablets.
Search is a very important function of any web and mobile app project. Depending on the nature of the project emphasis on search needs to be implemented. For example for CMS sites search all content not just pages, post but also all custom objects. If it is an eCommerce implementation, then in addition to searching product catalog, static content and blog; we implement predictive/type ahead search, weight based/weighted search, etc.
Social Network Integration
Social networks are great ways to share your information as a business. Every business has a page/account on social networks like Facebook, Twitter, Instagram, and Linked in. Simplest integration is link in header or footer to your social media accounts. A step further is to allow users who are interacting with your website to share a page/post/product on their network by posting it on their timeline or enable them to tweet it. If your site has my account, we recommend enabling login/registration using social network accounts. Lastly, it is even bigger statement for enabling users to share a transaction/purchase they recently made by enabling sharing feature 'Thank you' page.
