I believe that everybody already understands the importance of social media, and incorporating it into a web design. To get the attention of your viewers to your social media links you need to use both strategy and good taste. To design a good call-to-action social media icon/link you need to think about its positioning, its color, approach, style, size, everything. You also need to keep in mind that you want to get the attention of your viewers to the social side of your website without distracting from what’s important, such as the content. In my opinion, a good social media link is one that you have no trouble to finding and when you find it, you like what you see.
To give you some ideas of how you might integrate social media links in your next project, I’ve put together a collection of 55 Examples of Well Integrated Social Media Icons in Web Design. There should be plenty here to inspire you.
