Another example when the “nofollow" attribute can come handy are widget links. If you are using a third party's widget to enrich the experience of your site and engage users, check if it contains any links that you did not intend to place on your site along with the widget. Some widgets may add links to your site which are not your editorial choice and contain anchor text that you as a webmaster may not control. If removing such unwanted links from the widget is not possible, you can always disable them with “nofollow" attribute. If you create a widget for functionality or content that you provide, make sure to include the nofollow on links in the default code snippet.
Provide full functionality on all devices. Mobile users expect the same functionality - such as commenting and check-out - and content on mobile as well as on all other devices that your website supports. In addition to textual content, make sure that all important images and videos are embedded and accessible on mobile devices. For search engines, provide all structured data and other metadata - such as titles, descriptions, link-elements, and other meta-tags - on all versions of the pages.
Use social networks to expand your reach. Social networking is hugely important, and ensuring that you have a solid presence will have a large impact on your views. Post compelling content and you’ll soon build a loyal following. Follow and share with other users, who may reciprocate and follow you. There are a variety of ways that you can use social networks to extend your online presence, depending on the needs of your site.
Consider outsourcing article writing. If you hate the thought of generating content yourself, or your team is not writing-savvy, consider outsourcing this end of the task. Depending on the length, content, specialization and quality required, prices can start as low as US$5 per article. However, don't neglect attempting to write your own work - who better than you knows your own business, hobby or club and can express precisely what needs to be said?
If you are using Responsive Web Design, use meta name="viewport" tag to tell the browser how to adjust the content. If you use Dynamic Serving, use the Vary HTTP header to signal your changes depending on the user-agent. If you are using separate URLs, signal the relationship between two URLs by tag with rel="canonical" and rel="alternate" elements.
