As much as these may, or may not, be true, social media is still a very powerful tool to get messages out about what's going on with your business! The more consistent you are with sharing on social media, the more people will see your posts in their feed. Just because nobody reacts to your post doesn't mean they don't SEE it. Having sporadic posts spread out weeks/months at a time can actually send a negative message to page visitors. This can also leave room for your business to get lost in the mix of your competitors who are sharing more often. The more you share, the more you will stay front-of-mind to followers.
If you're looking to reach new followers, Facebook+Instagram paid advertising can be a great tool...but also a tricky one! Sharing Reels on Instagram can also reach people who don't follow you - but often take a bit of time & familiarity to put together. Knowing how to set up effective social media posts & ads can make a huge difference on your results, so seeking the help of someone with experience can not only save you time (time is money) but bring better results to grow your business.
