Hashtags — the 2025 truth
2018 advice: "use all 30". 2025 advice: 5-10 precision tags. Instagram's 2024 content-tag relevance classifier doesn't just check for "correct tags" — it measures content-category consistency. Putting #fitness on a dance video earns an instant penalty.
The mix that works
- 2-3 large tags (1M+ posts): discoverability
- 4-6 medium tags (50k-500k): competitive reach
- 1-2 narrow tags (5k-50k): hit your target viewer
- 1 branded tag: owned-search SEO
Frequently asked questions
Why not use all 30 hashtags?⌄
Since 2024, Instagram has shipped an "irrelevant hashtag" classifier. Posts using 5+ off-topic popular tags lose ~22% reach on average (Later 2025 report). 5-10 precise tags outperform 30 spammy ones.
Caption or first comment?⌄
In 2024 Adam Mosseri (Instagram CEO) explicitly recommended putting tags in the caption. The first-comment approach introduces a 1-3 minute delay and the algorithm's distribution score doesn't start until then.
Should I include my brand hashtag?⌄
Yes — including one branded hashtag (#YourBrand) is the recommended pattern for owned-search discoverability. The tool counts every # tag, branded or not.
Does it support non-Latin tags and emoji?⌄
Yes. #한강, #日本, #피크닉🌸 are all counted accurately via Unicode category matching (\p{L}).
