How does the hashtag generator work?

Describe your post and pick TikTok or Instagram. An AI model suggests hashtags and search words for the topic, then each tag is checked against the platform: how many TikTok videos and views it has, or how many Instagram posts. Tags nobody uses are left out, and the rest are sorted into broad, medium and niche.

How many hashtags should I use on TikTok?

3 to 5 relevant hashtags work best. TikTok reads them, along with your caption, speech and on-screen text, to decide who sees the video, so a few accurate tags beat a long list. The recommended set here is 1 broad, 2 medium and 2 niche tags.

How many hashtags should I use on Instagram?

Instagram allows up to 30, but 5 to 15 focused tags usually perform better than 30 loose ones. The recommended set here is 2 broad, 3 medium and 3 niche tags; add more from the lists if they fit.

What do broad, medium and niche mean?

Broad tags have huge volume (over a billion TikTok views, or over a million Instagram posts), so your post competes with countless others. Niche tags are small but specific, so it is easier to show up near the top. A mix of the three gives you both reach and a chance to stand out.

Where do the numbers come from?

From the platforms themselves, through SandBase APIs: tiktok/app-v3/hashtag-search-result for TikTok (videos and total views per hashtag) and instagram/hashtag-analytics for Instagram (posts per hashtag). Counts are checked when you run the tool and kept for 24 hours.

Should I use #fyp or #viral?

They are left out on purpose. Millions of videos use them every day and they say nothing about your topic, so they do not help TikTok find your audience.

Is there a hashtag API?

Yes. POST /v1/api/tiktok/app-v3/hashtag-search-result searches TikTok hashtags with their video and view counts, and POST /v1/api/instagram/hashtag-analytics returns the post count of an Instagram hashtag. Both are billed per call to your SandBase balance.

How to pick hashtags that work

Be specific#veganpastarecipe tells the platform more than #food. Niche tags put your post in front of people who want exactly that.
Mix the sizesOne or two broad tags for reach, the rest medium and niche so the post can rank in at least some of them.
Match the contentTags that do not fit the video or photo hurt more than they help. Leave out anything you would not search for to find this post.
