How many hashtags should I use?

Around 10 to 15 on Instagram, 3 to 5 on TikTok and YouTube, and 2 to 3 on X or LinkedIn.

Are the hashtags checked for volume?

No. They are chosen for relevance, so review them before posting.

Can I reuse the same set every time?

Better not to — vary tags to match each post's actual content.

About this tool

The best hashtag sets mix broad tags that have reach with niche tags where your post can actually be seen, rather than stacking only the biggest terms.

Platforms differ: Instagram tolerates long sets, while X and LinkedIn work better with two or three focused tags.
