Everything you need to know about hashtags and this tool.
Instagram allows up to 30 hashtags per post, but studies consistently show that 8–15 highly relevant hashtags outperform the maximum. Using all 30 can look spammy. We recommend 10–15 well-chosen hashtags combining high-reach and niche tags.
High-reach hashtags (e.g. #love, #instagood) have millions of posts — great for discovery but very competitive. Niche hashtags (e.g. #veganrecipesforkids) have fewer posts but a more targeted, engaged audience. The best strategy mixes both: use 3–5 popular tags for reach and 7–10 niche tags for targeted visibility.
TikTok recommends using 3–5 hashtags per video for best results. Always include #fyp or #foryou to target the For You Page algorithm, plus 2–3 niche hashtags relevant to your content. Avoid flooding captions with too many tags as this can look spammy to TikTok's algorithm.
Both placements work equally well for discoverability according to Instagram's own guidance. Many creators put hashtags in the first comment to keep their caption clean and readable. If you add them to the caption, consider adding a few blank lines or dots before the hashtags so they're visually separated from your main text.
Yes — though their role has evolved. On Instagram and TikTok, hashtags still directly influence content discovery and search. On LinkedIn, 3–5 hashtags improve professional reach. On Twitter/X, 1–2 trending hashtags per tweet are optimal. The key is using fewer, more targeted hashtags rather than spamming every post with 30.
It's not recommended. Instagram's algorithm may identify this as repetitive behaviour and reduce your reach. Rotate your hashtag sets — keep 20–30% consistent core tags and vary the rest based on the specific content of each post. Use this generator for each new piece of content to keep things fresh and relevant.
