How it picks hashtags
Describe your post and choose the platform, and Google's Gemini AI suggests a mix of hashtags: a few broad, popular ones for reach and several narrower ones that match your specific topic and audience. Your description is sent to Google to generate the suggestions, so keep it to what you'd publish anyway.
The suggestions are based on the model's general knowledge of how topics are tagged, not live trend data, so they won't reflect what's trending today.
How many to use on each platform
Platforms treat hashtags differently. Instagram allows up to 30, but a focused set of about 3-5 relevant tags generally works better than a long list. On X, one or two hashtags are plenty; more eat into the character limit and read as spam. TikTok uses hashtags with captions and search to understand topics, so a few specific ones help. On LinkedIn, around 3-5 professional tags at the end of a post is typical.
Relevance beats volume everywhere. A broad tag like #travel is crowded with millions of posts; a specific one like #lisbontravel reaches fewer but far more interested people.
Before you post
Check each suggested tag on the platform first. Some innocent-looking hashtags are used for unrelated or inappropriate content, and platforms sometimes restrict tags that have been abused, which can hide your post.
Mix in your own branded tag if you have one, and avoid repeating the identical set on every post; varying tags to match each post's content looks more natural to both people and platform algorithms.
Frequently asked questions
How many hashtags should I use on Instagram?
Instagram allows 30, but a handful (about 3-5) of closely related tags usually performs better than a long generic list.
Are the hashtags based on current trends?
No. They come from the AI model's general knowledge, not live data, so check trending topics on the platform itself.
Is my post description stored?
