The rumor that third-party tools like schedulers can ruin social media engagement has existed since 2018. Some marketers believe that social networks like Facebook and Twitter have put a "cap" or limit on the reach of scheduled posts to force users to use their native scheduling tools. However, the real culprits behind poor engagement are low-quality content and inconsistent posting.
Each platform will have its bragging rights regarding how much it has boosted social media engagement for its users. In a recent blog post on the subject, Buffer stated that its latest study showed a 10.3% growth in engagement on social channels following the use of scheduling tools.
