Social media can be a virtual blackhole for your time and creativity, especially if you maintain a presence on several. Using the same post for as many as possible, which will undoubtedly reach slightly different audiences, can help save time as well as your sanity. Maintaining a list of posts that you can cut and paste versus creating each time is another time-saver.
In some cases, it’s worth it to take a class or spend some time on the various apps to discover some of the tricks that increase efficiency. For example, Pinterest is more than a place to post cute pictures. You can include a link to your website or a buy link after grabbing a potential customer’s attention with an original graphic or meme.
