A few years ago the recipe was well known: post the image, paste thirty hashtags from a ready list into the first comment, and wait for reach. A lot has changed. Platforms now understand image, video and text content on their own; some have imposed strict hashtag limits, and some ignore all of them past a certain number. Even so, hashtags are still useful — used the right way.
This guide explains what hashtags do today, each platform’s limits, how to write Arabic hashtags that don’t break, and how to choose a small number that genuinely serves your content.
What do hashtags do today?
Hashtags are no longer a magic “reach engine”. Platforms rely mainly on how people engage with content and on their own understanding of its topic to decide who sees it. A hashtag’s role now is closer to classification: it helps the platform understand the post’s topic precisely, places it on the hashtag page for people browsing it, and gathers a campaign’s or event’s content in one place.
In other words: a few precise hashtags that describe the content beat a long generic list.
Each platform’s limits
| Platform | Limit or recommendation |
|---|---|
| Maximum of 5 hashtags per post and Reel | |
| YouTube | Above 15 hashtags, YouTube ignores all hashtags on the video |
| TikTok | No strict count, but 3–5 precise hashtags is the common recommendation — and they all count toward the caption limit |
| A few (3–5) is enough | |
| X | Usually one or two at most, since they eat into the character limit |
| A few (1–3), if any |
These limits change — Instagram in particular cut its limit sharply from the previous 30. Our hashtag formatter warns you immediately if you exceed the limit for the platform you choose, and shows how many to remove.
Writing Arabic hashtags correctly
A hashtag ends at the first space or punctuation mark. So «#عروض الجمعة البيضاء» becomes just «#عروض», with the rest as plain text. The rules:
- No spaces: join words with an underscore:
#عروض_الجمعة_البيضاء. This form is very common for Arabic hashtags and easier to read than merging words. - No punctuation: hyphens, full stops, commas and question marks break the hashtag.
- No diacritics or tatweel (ـــ): «#رمضـــان» is a different hashtag from «#رمضان» and won’t appear with the content under it.
- Watch common spellings: «#الرياض» and «#رياض» are different hashtags. Search the platform to see which is actually used.
- Numbers are allowed inside a hashtag, but a hashtag made only of numbers usually doesn’t work.
- For English: CamelCase like
#WhiteFridayis easier to read — and better for screen readers — than#whitefriday.
The formatter converts plain words into valid hashtags automatically: it strips punctuation and tatweel, joins multi-word phrases the way you choose (underscore, merged, CamelCase) and removes duplicates.
Why doesn’t our tool suggest “trending” hashtags? Because good hashtags are chosen for your content and audience, not from a generic list. Random lists place your post next to unrelated content and can blur the platform’s understanding of your topic.
How to choose your hashtags
Think in three layers and pick one or two from each:
- Topic hashtag: describes the post precisely (
#عبايات_شتوية“winter abayas”, not#موضة“fashion”). - Audience or place hashtag: who you want to reach (
#الرياض“Riyadh”,#أمهات_السعودية“Saudi mums”). - Brand or campaign hashtag: your brand or campaign name, gathering your content and your customers’ content.
Ask of every hashtag: if someone searched it, would they be glad to find my post? If not, remove it.
The branded hashtag: an overlooked tool
A hashtag for your brand or a specific campaign gathers customer-generated content (UGC) in one place and makes it easy to reshare and engage with. Keep it short, easy to spell and unique (search it first to make sure it isn’t used for something else), and put it in your bio, on packaging and on the thank-you card inside orders.
Where to put hashtags
- End of the caption is the cleanest option on most platforms, after the text and call to action.
- Inside a sentence can suit one natural hashtag, but overdoing it hurts readability.
- The first comment was popular for hiding long lists; with new limits and smaller numbers it’s usually unnecessary.
- YouTube: the first three hashtags in the description may appear above the video title, so put the most important first.
Hashtags count toward the caption’s character limit, so check the full length with our character counter — especially on X.
Mistakes that do more harm than good
- The same list on every post regardless of topic.
- Trending hashtags unrelated to the content to ride the wave — they bring exposure to the wrong audience and can look spammy.
- Very generic hashtags (#love, #photo) where a post drowns in seconds.
- Broken hashtags caused by spaces or tatweel.
- Exceeding the platform limit — especially on YouTube, which cancels all hashtags above 15.
How to know hashtags are working
Instagram and TikTok insights often show where a post’s reach came from. Try changing hashtags on similar posts and compare, remembering that the content itself matters far more. Measure the end result through real engagement with our engagement rate calculator, not by the number of hashtags.
A worked example: from a random list to five hashtags
An abaya store in Riyadh posted every update with this list: #fashion #style #beauty #instagram #saudi #abayas #shopping #offers #new #love and more, up to thirty.
The problems: very generic hashtags where posts drown, others unrelated to the content (#love, #instagram), the same list on every post, and a count above Instagram’s current limit.
For a post about a new winter crepe abaya, the three-layer list becomes:
- Topic:
#عبايات_شتوية(winter abayas),#عباية_كريب(crepe abaya) - Audience and place:
#عبايات_الرياض(Riyadh abayas),#ستايل_محتشم(modest style) - Brand: the store’s own branded hashtag
Five hashtags, all genuinely describing the post, with the first layer changing for each product. Paste the words into the hashtag formatter and choose Instagram to convert them and check the count before posting.
Key takeaways
- Hashtags are now a classification tool, not a magic reach engine.
- Respect each platform’s limit: 5 on Instagram, never more than 15 on YouTube.
- Join Arabic hashtag words with underscores, without diacritics, tatweel or punctuation.
- Choose from three layers: topic, audience or place, and brand.
- Change topic hashtags with every post instead of repeating one list.
Frequently asked questions
Arabic or English hashtags?
Whatever your audience speaks and actually searches with. For a Saudi audience, usually Arabic — with one English hashtag if your audience uses it.
Do hashtags increase followers?
Rarely directly. Good content brings followers; hashtags help the platform deliver it to the right audience.
Should I use hashtags in Stories and Reels?
For Reels, treat them as you would a post: a few in the caption, within the platform limit. In Stories, a hashtag sticker can add the Story to the hashtag page, but its effect is limited — use it for a campaign or event hashtag rather than a generic list.
Can an account be “banned” because of hashtags?
Using hashtags that break platform policies, or repeatedly overusing unrelated ones, can reduce a post’s reach. Stick to a few precise hashtags.
Fewer, sharper, correctly written hashtags: that’s the strategy for 2026. Format your hashtags and check every platform’s limits with our free hashtag formatter — and if you want a complete content plan for your brand’s accounts, get in touch.
