Integrating social media services in your website design is vital if you want to make it easy for readers to share your content. While some users are happy with the social media buttons that come built into their design template, the majority of WordPress users install a plugin to automatically embed sharing links on their pages. Many of you will find that a plugin does exactly what you need; others not so much. Some are poorly coded, and most include services that you just don’t need. And while some great social media plugins are out there, they don’t integrate with every WordPress design.
If you aren’t comfortable editing your WordPress templates, a plugin is probably the best solution. If you are comfortable making a few edits to your theme, then consider manually integrating social media so that you have more control over what services appear on your website.
