Yes, hashtags still work on Facebook, but as labels rather than a reach button. A hashtag turns a word or phrase into a clickable link to a feed of posts that use it, and Facebook says hashtags help people find reels in search. Facebook publishes no hard limit, and Meta's Facebook for Creators Page says content with no more than five hashtags performs best.
Facebook hashtags don't follow the same rules as Instagram's. This guide sticks to what Facebook and Meta document: where hashtags work, who sees tagged posts, how many to use, how to write them, and how they differ from tagging people. Anything that comes from marketers rather than Meta is labeled.
Facebook's Help Center says hashtags turn topics and phrases into clickable links in posts on your profile, your Page or in groups. To make one, type # followed by the topic, with no spaces, as in #dogs. Select a hashtag and Facebook opens a feed of posts that include it, sometimes with related hashtags at the top. You can also type a hashtag into the search bar.
Reels take hashtags too, and reels now cover most video. Since a September 2025 update, Facebook shares every video you post (except stories and live video) as a reel, whatever its length or orientation. When you upload one from a computer, the Describe your reel… field takes a description and hashtags, and Facebook's help page says hashtags help other people find your reel when searching.
What Meta doesn't say is that hashtags push a post into more people's feeds. Its published explanations of how Facebook ranks Reels and Search results list signals such as how often a reel is watched to completion, how closely its topic matches what you usually watch, a post's likes, its age and its click-through rate. Hashtags aren't on either list. Treat them as labels that make a post easier to find, not as a lever for reach.
Who can see a post with a hashtag
Adding a hashtag never widens your audience. According to Facebook:
- Friends-only posts show up in that hashtag's feed for your friends.
- Public posts appear on your public profile and in the hashtag's feed when you also allow people to follow you.
- Viewers only see posts that were shared with them, so the same hashtag feed can look different from one person to the next.
- Private group posts stay inside the group, because only current members can see what's shared there. In a public group, anyone on or off Facebook can see what's shared.
- Reels follow the audience you pick. A non-public reel is visible only to that audience.
Facebook doesn't publish a hard cap on hashtags per post. The closest thing to an official number is an October 2025 FAQ from Meta's Facebook for Creators Page: content with no more than 5 hashtags performs best, and irrelevant hashtags can make your content's reach suffer in the long run. The same FAQ says captions should be short and relevant to the post's topic.
Everything beyond that comes from third parties. A widely quoted Facebook hashtag study dates from 2014, when the analytics firm Socialbakers looked at 200,000 posts and found that engagement dropped once posts used more than two hashtags. It's more than a decade old and predates Facebook Reels, so read it as history, not a benchmark.
A sensible default: one to three hashtags on everyday posts, up to five when a post or reel is meant to be found through search, and never a block of trending tags.
Where to put them
Facebook's help pages don't say where hashtags should go, but accessibility guidance does. CUNY's accessibility toolkit recommends putting hashtags and mentions at the end of a post, because screen readers read out the # and @ symbols, which is disruptive mid-sentence. One hashtag that reads naturally in a sentence is fine; a set belongs at the end.
Facebook and Instagram are both Meta apps, but they handle hashtags differently in a few ways that matter if you post to both.
| Facebook | Instagram |
|---|
| Limit | No published cap; Meta suggests 5 or fewer | Up to 5 per post |
| Where you add them | Post text, reel description | Caption or comments |
| Private content | Shown only to the post's audience | Private profiles' posts don't appear publicly on hashtag pages |
| Problem hashtags | You can report one from search | Some hashtags are made unsearchable |
Instagram's Help Center says a hashtag can become unsearchable when its text, or the content associated with it, consistently breaks Instagram's Terms of Use or Community Standards. Facebook's hashtag help pages explain how to report a hashtag but don't say when hashtags get restricted, and neither app's help pages list which tags are affected.
If you reuse an Instagram set on Facebook, check each tag's Facebook feed first. For Instagram-only sets, use the Instagram hashtag generator; LinkedIn is covered in our guide to LinkedIn hashtags.
- Make it one word. Facebook says a hashtag must be written as a single word, without spaces: #FarmersMarket, not #Farmers Market.
- Use numbers, not punctuation. Numbers are allowed, but punctuation and special characters such as $ and % won't work. #Summer2026 is fine, and #MothersDay beats #Mother'sDay.
- Capitalize each word. Without capitals, screen readers can't pick out the separate words in a hashtag, so write it in PascalCase: #SmallBusinessSaturday. Capitals also help people with dyslexia or cognitive disabilities read it. camelCase (#smallBusinessSaturday) works too.
- Keep the letters plain. Font generators swap letters for Unicode look-alikes (𝗯𝗼𝗹𝗱, 𝘪𝘵𝘢𝘭𝘪𝘤, 𝓈𝒸𝓇𝒾𝓅𝓉) that are different characters from a, b and c. Facebook doesn't document how it treats them in hashtags, so a styled tag may not link at all, or may lead to a different feed than the plain one. Screen readers may also skip a styled word or read it out character by character. Our explainer on why fancy text breaks hashtags goes deeper.
- Keep it short and on topic. Meta's creator advice for hashtags and captions is to keep them short, clear and on topic.
If you want emphasis, put it in the words, not the tags. Style one opening line with the Facebook text formatter and keep hashtags, keywords and names plain. Here's how bold text works in a Facebook post.
People who search for a "Facebook tag generator" usually want one of two things, and Facebook treats them very differently.
- A hashtag (#) labels a topic. Anyone who can see the post can select it to browse other posts on that topic.
- A tag or mention (@) links a specific person, Page or group. Type @ and the name, then pick the right account from the list that appears. Depending on a Page's settings, you may not be able to mention it.
Tags come with side effects that hashtags don't have. Facebook says that when you tag someone:
- they're notified;
- the post may be added to their profile;
- the post could become visible to the audience you chose plus the tagged person's friends;
- if you aren't friends, they may get to review the tag before it appears on their profile.
A tag has to point to a real account, so a generator can only suggest hashtags, not tags. Tag only the people and Pages that are actually in the post or behind it; each tag sends a notification.
BoldlyType's free Facebook hashtag generator turns a short description of your post into a list of ideas. It sends what you type to our server to generate the list, never posts anything, and can't see your photos or videos.
- Open the generator.
- Under What's the post about?, describe the post in a sentence, such as "Saturday sourdough class for beginners at our bakery."
- Optionally, fill in Target audience, such as "home bakers."
- Select Generate Facebook hashtags. You get 25 ideas on one line, mixing broad, mid-size and niche tags.
- Shortlist the three to five that describe the post best.
- Search each one on Facebook and open its feed. The generator doesn't look up real usage, so this is where you confirm a tag is active, on topic and free of spam.
- Rewrite the keepers in PascalCase and add them to the end of your post.
For the words around the hashtags, the Facebook caption generator drafts captions, and the character counter has a Facebook post preset for checking length.
What can go wrong
- Irrelevant hashtags. The Facebook for Creators FAQ warns that irrelevant hashtags can hurt your content's reach over time. A bakery post tagged #WorldCup is an obvious case.
- Stuffing and spam. Meta's spam policy bans content meant to deceive, mislead or overwhelm people to artificially increase views, and it bans buying, selling or exchanging engagement, which it says includes use of specific hashtags. Piling unrelated trending tags onto a post is hard to square with the first rule; offering cash or anything else of monetary value for using your hashtag breaks the second.
- Restricted hashtags. A tag full of rule-breaking posts is a bad place for yours. Open a hashtag's feed before you use it, and skip any that are full of spam or off-topic posts. If one clearly breaks the rules, you can report it: search for it, open the Options menu and choose Give feedback or report topic.
- Posts that never show up. A Friends-only post, a private-group post or a non-public reel won't appear in the hashtag feed for anyone outside that audience. Facebook says a profile post appears in a hashtag's feed when you share it publicly and allow people to follow you.
- Broken tags. A space, apostrophe, symbol or styled letter can break a hashtag. Check the post after publishing and fix it with Edit post, except on Page posts that are boosted or part of an ad campaign, which Facebook doesn't let you edit.
- Expecting a reach jump. Hashtags don't appear among the signals Meta lists for ranking Reels or Search. The signals that do, such as completed views and likes, depend on the post itself.
