Full definition
A hashtag is a word or phrase preceded by # that groups content by topic. Hashtags matter less on Facebook than on Instagram. Best practice: use 2-3 hashtags per Facebook post — no more.
📌
Why it matters
Hashtags behave differently on every network, and the difference is decisive. On Instagram they are a discovery channel; in a Facebook group they are usually noise that signals the post was copied from somewhere else.
🧮 A worked example
A caption with 18 hashtags works nicely on Instagram. The same text in a local Facebook group reads as spam, and members scroll past before the first sentence.
⚠️ The common mistake
Copy-pasting an Instagram post into a group. Format, length and hashtag count all need to change with the venue.
