Hashtags are labels that categorize Instagram content and make it discoverable to users who follow or search those topics. Understanding how they actually function, and how Instagram's algorithm treats them, helps you use them effectively rather than copying generic advice that no longer applies.
How Hashtags Work Technically
When you add a hashtag to a post, Instagram indexes your content under that tag. Users who follow a hashtag may see your post in their feed. Users who search for that hashtag may find your post in search results. Instagram also uses hashtags as a signal to understand what your content is about, helping the algorithm serve it to users interested in related topics.
The Role of Hashtags Has Changed
In earlier years, heavy hashtag use (30 hashtags per post) was standard practice and significantly boosted reach. Instagram's algorithm has evolved. In 2026, hashtags are less powerful as a standalone reach tool than they once were. The algorithm now distributes content primarily based on engagement signals and audience interest matching, not hashtag volume.
This doesn't mean hashtags are useless, they still play a categorization role and can help niche content reach interested audiences. But the focus should be on quality and relevance over quantity.
Best Practices for Instagram Hashtags in 2026
Use Fewer, More Relevant Hashtags
3–10 highly relevant hashtags typically outperform 30 generic ones. Instagram itself has suggested that 3–5 focused hashtags often work better than maximum usage. Each hashtag should be directly relevant to your specific post, not just to your business category in general.
Mix Hashtag Sizes
Hashtag size refers to how many posts use that hashtag. Very large hashtags (#food has billions of posts) mean your content competes with enormous amounts of other content and is quickly buried. Very small hashtags mean very few people are browsing them. A mix of mid-size hashtags (50,000 to 500,000 posts) and smaller niche hashtags typically performs best.
Use Arabic Hashtags for Saudi Content
For content targeting Saudi Arabic speakers, Arabic hashtags are essential. Arabic-language users search and follow Arabic hashtags. A restaurant in Riyadh should use hashtags like #مطاعم_الرياض alongside English hashtags, both to reach different audience segments and to signal content language to the algorithm.
Location Hashtags
Location-specific hashtags, #Riyadh, #الرياض, #Jeddah, neighborhood names, help local businesses reach local audiences browsing location-tagged content. These are particularly valuable for businesses with a physical location.
What Works Better Than Hashtags for Reach
High-quality Reels, consistent engagement from your existing audience, and shareable content all drive more reach than hashtag optimization alone. Hashtags are one small part of a broader content strategy. For the full picture, read How Social Media Algorithms Work.
How Many Hashtags to Use, and Where to Put Them
Instagram allows thirty hashtags per post, and using all thirty has been poor practice for several years. The platform's own guidance points to three to five well chosen tags, and accounts that drop from thirty to five commonly see no fall in reach at all, which tells you most of those thirty were doing nothing. A wall of tags also signals a certain kind of account, and that signal is read by people as well as by ranking systems.
Placement matters less than people claim. Tags in the caption and tags in the first comment are treated the same way for discovery, so choose based on how you want the post to read. Putting them in a first comment keeps the caption clean, which is worth more on a post whose caption is doing persuasive work. Tags added after publishing still function, though a post's early performance is decided in the first hour, so late additions rarely rescue anything.
The one rule with real consequences is relevance. A tag that has nothing to do with the content teaches the platform to show your post to people who will scroll past it, and that early rejection suppresses distribution far more than a missing tag ever would. Five accurate tags outperform twenty aspirational ones.
Building a Hashtag Set for a Saudi Business
Useful sets mix three tiers rather than chasing volume. Broad tags in the millions put you in a feed you will never rank in, so treat them as context rather than reach. Mid-sized tags, roughly ten thousand to two hundred thousand posts, are where a small account can genuinely surface. Narrow tags, under ten thousand, reach few people but almost all of them are relevant, and they are where enquiries actually come from.
Location changes the arithmetic here. A tag like #الرياض carries enormous volume and almost no intent, while #كافيهات_الرياض or #عيادات_جدة is small, specific and full of people deciding where to go this evening. Arabic tags behave differently from their English equivalents, and both are worth holding, since a bilingual audience searches in whichever language it happens to be thinking in. Check each Arabic tag manually before adopting it, because transliteration and spacing conventions vary and some spellings are effectively dead.
Keep three or four sets rather than one, matched to what you post: a set for product or menu posts, one for behind-the-scenes material, one for location-led content, and one for seasonal moments such as Ramadan or the National Day. Rotating between sets keeps tags aligned to content and avoids the identical block appearing under every post, which readers notice even when algorithms do not.
Hashtags on Reels, Stories and Carousels
The three formats do not behave alike. Reels draw most of their distribution from the recommendation system, which reads the video itself, the audio, the on-screen text and the caption, so tags contribute at the margin. Two or three relevant tags are worth adding, and a long list is not. What genuinely moves a Reel is how much of it people watch and whether they send it to someone.
In Stories, hashtags can place you in a location or tag story, but the far more valuable tool is the location sticker, which for a local business puts you in front of people browsing that place. One location sticker and at most one hashtag sticker is the sensible pattern, since Stories cluttered with stickers get tapped past.
Carousels are where tags still carry weight, because they surface in search and hashtag results and are saved more often than any other format. A carousel that answers a specific question, tagged with the terms someone would search to find that answer, keeps arriving through search for months. Saves also signal usefulness, and usefulness is what earns continued distribution.
Measuring Whether Your Hashtags Do Anything
You do not have to guess. Instagram Insights breaks down where each post's views came from, and the line to read is impressions from hashtags. Check it across ten or fifteen posts and a pattern appears quickly: for most local Saudi accounts, hashtags supply somewhere between two and ten percent of reach, while the explore and reels surfaces supply most of the rest. Knowing your own figure tells you how much attention the topic deserves.
Test properly rather than changing everything at once. Run one set for two weeks, then a different set for two weeks on comparable content, and compare hashtag impressions rather than total reach, since total reach moves for reasons that have nothing to do with tags. Any tag contributing nothing across a month of posts can be dropped without ceremony.
Then spend the attention you free up on what the same Insights screen shows matters more: saves, shares, and how many people who saw the post visited your profile. Those three predict whether an account grows. Hashtags are a small optimisation on top of content that already earns attention, and no set of tags compensates for a post nobody wanted to watch.
