Frequently asked questions
Where do the hashtags come from?
They come from fixed lists written into the tool, not from live data. For each of the 12 niches there are three hand-written banks of five tags (small, medium and large), plus a short list for each platform, plus the words from your topic field. Nothing is fetched, so the tool cannot see how many posts a tag has today or whether a tag is restricted.
In what order are the hashtags put together?
Topic words first, then the platform tags, then the niche banks, and the combined list is cut off at the number you picked. That means a small count keeps your topic words and platform tags and may never reach the niche banks. Choosing 10 for “home workout”, Instagram and fitness returned #home #workout #instagram #instadaily #reels #explore #homeworkout #fitnessmotivation #strengthtraining #personaltrainer.
Why did I get fewer hashtags than I selected?
The pool is limited to your topic words plus the platform tags plus at most 15 niche tags, and duplicates are removed before counting. “Vegan meal prep!!” on TikTok in the food niche with small-only tags and a count of 30 produced 18 tags. Asking for 30 only returns 30 when the pool really holds that many.
How are my topic words turned into hashtags?
The text is lower-cased and split on spaces and commas. Words shorter than two characters and a short list of filler words such as “the”, “and” and “for” are dropped, and anything that is not a letter or number is stripped. Each remaining word becomes its own tag, so “vegan meal prep” gives #vegan #meal #prep, never #veganmealprep. Accented letters are kept, so “café” becomes #café.
Do the small, medium and large labels reflect real post counts?
No. They are the tool’s own grouping of the hard-coded lists, and the code holds no post counts. Open a tag inside the app to see how busy it is before relying on the label. The “Mixed” setting simply uses all three banks, “Small niche only” uses the small bank, and “Large / viral only” uses the large bank.
Why does the groups section show tags that are not in the copy-ready list?
The copy-ready line is trimmed to your count and follows your size setting, while the groups block always shows the first five tags of the niche, medium and large banks for reference. In the home workout run, #fitness and #health appear in the groups block but not in the ten copy-ready tags.
Does it check for banned tags or predict reach?
No. It does not check whether a tag is restricted on a platform, does not rank tags, and cannot say what a tag will do for a post. The platform tags it adds, such as #fyp for TikTok or #socialmedia for “All platforms”, are plain suggestions you can delete.
Hashtag generator — a niche-based tag list built from fixed banks
How the list is assembled
The generator builds one pool and trims it. Your topic words go in first, followed by the tags tied to the chosen platform, followed by the niche banks selected by the size setting. Duplicates are removed and the first 10, 20 or 30 are kept. Because the order is fixed, the number you choose decides which sources survive the cut.
| Order | Source | Contents |
|---|---|---|
| 1 | Topic words | One tag per word you typed, minus filler words |
| 2 | Platform tags | 2 to 5 fixed tags, for example #reels or #networking |
| 3 | Niche banks | Small, large, or all three banks of five tags each |
| 4 | Trim | Duplicates removed, then cut to the selected count |
Worked examples
These outputs came straight from the generator.
| Settings | Tags returned | Result |
|---|---|---|
| “home workout”, Instagram, fitness, 10, mixed | #home #workout #instagram #instadaily #reels #explore #homeworkout #fitnessmotivation #strengthtraining #personaltrainer | 10 tags |
| “vegan meal prep!!”, TikTok, food, 30, small | #vegan #meal #prep #fyp #foryou #foryoupage #viral #trending #homecooking … #consciousliving | 18 tags |
| “the AI tools for you”, Twitter / X, tech, 20, large | #ai #tools #trending #twitter #tech #internet #digital #data #future #life #love #happy #instagood #beautiful | 14 tags |
| No topic, LinkedIn, business, 30, mixed | #linkedin #professional #networking #career #founderstory … #finance #success #hustle | 19 tags |
What the size setting changes
Mixed pulls from the small, medium and large banks, so it has the biggest pool. Small niche only and Large only each use one bank and also add the lifestyle bank of the same size, which is why the vegan example ended with #slowliving and #consciousliving after the food tags. Those lifestyle tags were never about food, so scan the result and delete any that do not fit your post.
Reading the third example
The Twitter / X run shows two details worth knowing. Filler words such as “the”, “for” and “you” were dropped from the topic, but the two-letter word “ai” survived and became #ai. And because the large setting adds the lifestyle bank, generic tags like #love and #happy ended up in a tech list. They sit at the end of the output, so a count of 10 would have removed them.
Edit before you post
Treat the output as a draft. Remove tags that do not describe the post, check any tag you are unsure about inside the app, and keep the number to what suits the platform. The generator makes no promise about reach, and the lists do not change unless the tool itself is updated. A practical routine is to generate once for the post, delete anything off-topic, then save the cleaned list as a reusable starting set for similar posts. If the same topic words keep producing awkward tags, rephrase the topic into fewer, more specific words, because every word you type becomes its own tag.
