Duplicate Hashtags
Platforms may penalise repeated hashtags. Remove duplicates for better reach.
Use the free Hashtag Counter to instantly count how many hashtags are in your caption or post, identify duplicate tags that can hurt your reach, and check whether your hashtag count is within the recommended limits for Instagram, TikTok, Twitter/X, LinkedIn, Facebook, and Pinterest — all without leaving your browser.
Instagram allows a maximum of 30 hashtags per post or reel. However, studies suggest that using 3–10 highly relevant hashtags performs better than stuffing all 30, as Instagram's algorithm may limit reach for posts that appear spammy.
Twitter/X does not enforce a hard hashtag limit, but the overall 280-character tweet limit applies. Best practice is to use 1–2 targeted hashtags per tweet — more than that tends to reduce engagement.
Posting the same hashtag multiple times in one caption does not increase visibility and some platforms (especially Instagram) may flag the post as spam, reducing its organic reach. This tool highlights all duplicates and offers a one-click deduplicated copy.
