On Facebook you want to avoid being an account that spams its followers. If you post too often, it can make people leave your page. While there is no clear answer for anything in the social media world, one of the most popular frequency post rates is two posts per day. However, if you have less than 10,000 likes on your page, this strategy may actually hinder your engagement. Instead, you may want to try only posting once a day or a few times a week. By limiting your posts, those posts will get through to more of your audience and you could see better results. Once you have over 10,000 likes, the twice a day rule may be the optimal way for you to get click-throughs to your site and see more constant engagement. Be careful about posting more than twice a day unless you are sure how your audience will react. Increasing the number of posts occasionally, such as during special events and occasions, is fine, but do it too often and you might have more people leaving than engaging with your page.
Now, Twitter can be a different beast. Staying active on Twitter is important. In order to be using Twitter to its full advantage, it is recommended to check in a few times a day. Try to tweet at least once a day at a minimum to stay active on the platform. On average, people tend to post one to four times a day, but unlike Facebook there is generally no negative repercussion for posting more often than that. There are some people who post a tweet an hour in hopes of reaching their audience while they are online.
The professional network of LinkedIn differs from other social media. At most, one update a day is all you need to get your post out there and be seen by either your connections or people who have liked your business page. It is very rare to see people post multiple times in a day. Unlike other social networks, people tend to log into LinkedIn only once or twice a day, and they don’t tend to sit with it open too often. Give your audience time to receive your update before bombarding them with a new one.
Remember, in addition to the time you are posting on these social accounts, the frequency of these postings matters almost even more, if your audience is used to hearing from you two times a day, it may reflect negatively on your engagement if you take your postings down to just one.
These are of course just guidelines. You need to experiment and find what works best for your agency. Also, remember to change it up every so often and don’t be afraid to try something new.
