0 - 3 tags: Light use.
Often enough when the caption itself explains the topic.
4 - 10 tags: Moderate use.
Can work for discovery if the tags are specific and relevant.
Repeated tags: Clean up.
Duplicate tags rarely add value and make captions look messy.

FAQ
Common questions
What counts as a hashtag?
The counter detects words that start with # and use letters, numbers, or underscores.
Does it tell me which hashtags will rank?
No. It counts and cleans up tags. Platform performance still depends on content, audience, niche, and timing.
Why count unique hashtags?
Unique count helps catch repeated tags that slipped into a caption during editing.
Do text tools publish final copy?
No. Treat generated or checked text as a draft. Review tone, factual accuracy, claims, brand voice, platform fit, and any legal or policy requirements.
Why should platform limits be rechecked?
Platforms can change limits, truncation behavior, display formats, and policy rules, so verify important posts in the publishing interface.
