How to Track the Hashtags Your Competitors Use on Instagram
Reading Hashtags as Labels and Campaign Markers, Now That There Are Only Five
Short answer
Track competitor Instagram hashtags by counting how often each tag appears across their last thirty posts. Sort the tags into branded, campaign, category and community types. Instagram now limits captions to five hashtags, so each one is a deliberate label. Read them for positioning and campaign timing, not as a reach formula.
1. What changed about Instagram hashtags, and why does it matter for competitor research?
In December 2025 Instagram announced it would gradually limit captions on posts and Reels to five hashtags. A competitor's hashtags are now a short, curated list rather than a block of thirty, which makes them far easier to read.
Instagram said it would update the number of hashtags allowed in a caption for a Reel or post to five, and that fewer, more targeted hashtags can improve content performance and people's experience [s1]. Instagram's leadership had already said earlier in 2025 that hashtags do not work to increase reach, while remaining a way to tell people what a post is about.
For research, that changes the question. You are no longer reverse-engineering a reach trick. You are reading how a competitor labels their own content: which topics they want to be found under, which campaigns they run and which communities they want to belong to.
2. How do I log a competitor's hashtags?
Take their last thirty posts, copy every hashtag into one row per post, note where it sits, and count frequency across the set. A frequency table is the whole dataset.
- Collect thirty recent posts. Use posts and Reels from the last one to three months, depending on cadence. Record the post date and format next to each set of hashtags so you can split by format later.
- Copy the hashtags exactly. Keep spelling and capitalization as written. #VeltrixTips and #veltrixtips resolve to the same tag, but a brand that writes it in camel case consistently is treating it as a brand asset.
- Note where each hashtag sits. Record whether it is in the caption body, at the end of the caption, or in the first comment. Placement tells you whether they treat hashtags as part of the message or as metadata.
- Count frequency across the set. List every unique hashtag and how many of the thirty posts used it. Tags on most posts are their core labels. Tags that appear in a burst over two weeks are almost always a campaign.Log the posts with no hashtags too. A competitor that stopped using them entirely has made a decision worth noting.
3. What kinds of hashtags do competitors use, and what does each reveal?
Four types: branded, campaign, category and community. Branded tags show what they want to own, campaign tags show timing, category tags show positioning, and community tags show who they want to be seen alongside.
| Type | Example (invented) | What it reveals | What to check |
|---|---|---|---|
| Branded | #Veltrix, #VeltrixTips | A content series or brand asset they are building | Whether customers use it too, on the hashtag page |
| Campaign | #SonderaSpringLaunch | A campaign window, often with a start and end date | The same dates in their ads and landing pages |
| Category | #SalonSoftware, #SmallBusinessTools | The topics and segments they want to be found under | Whether the category matches their homepage positioning |
| Community | #SalonOwners, a city or event tag | The audience or scene they want to be associated with | Whether they engage there beyond tagging |
Category tags are the most useful for positioning work. If Norvane tags every post with #FitnessCoaches while their homepage talks about salons, either the homepage is behind or they are testing a new segment on social first. Both are worth knowing.
4. How do I check whether a competitor's branded hashtag has real adoption?
Open the hashtag and look at who is posting under it. If most posts come from the brand itself, it is a label. If customers and creators use it unprompted, it is a community asset.
Scroll the hashtag page and sort what you see into three groups: the brand's own posts, creator or partner posts, and ordinary customers. Hashtag pages show a selection of posts rather than a guaranteed complete, chronological list, so treat this as a sample, not a census.
Customer adoption is the signal worth tracking. A branded tag customers use for their own photos is free user-generated content and social proof for the competitor, and it tends to grow slowly and hold. A tag used only by the brand and paid partners is a campaign label and will disappear when the campaign does.
Should I use a competitor's branded hashtag?
No. It puts your content inside their community asset, where it looks either confused or opportunistic, and it helps them more than you. Use the category and community tags you genuinely belong to, and build your own branded tag only when you have a recurring series or a customer behavior worth naming.
5. How do hashtags help me spot competitor campaigns?
A new tag appearing on several posts within a short window, then fading, marks a campaign. Its first and last dates give you the campaign window, which you can match against their ads and site changes.
Keep a simple timeline: for each campaign tag, the first post date, the last post date and the number of posts. Across a year, that timeline shows when a competitor runs pushes and how long each lasts, which is exactly what you need to plan around their peaks.
Match the window against other channels. A campaign tag on Instagram that coincides with new Meta ads and a new landing page is a coordinated launch. A tag that appears only on Instagram is a social-only initiative, typically smaller and more experimental.
6. What should I not conclude from competitor hashtags?
Do not conclude that a hashtag drove a post's reach, and do not copy a competitor's set expecting their results. Instagram itself describes hashtags as labels rather than a reach lever.
It is tempting to line up hashtags against engagement and look for the magic tag. With five tags per post and every other variable changing at once, the correlation is almost always coincidence, and Instagram has said plainly that hashtags are not a way to increase reach.
What hashtags reliably tell you is intent: how a competitor wants their content understood. That is a positioning signal, and it belongs next to their captions and their homepage headline rather than in a performance report.
Oppira collects the posts and Reels of the competitors you follow with their full captions, and you can ask its AI agent about what they are posting, which makes a hashtag frequency count or a campaign timeline a question rather than a spreadsheet.
Key Takeaways
Five hashtags means every tag is a choice
Instagram's cap turned competitor hashtags from noise into a short, deliberate list of labels.
Hashtags are labels, not reach
Instagram describes them as a way to say what a post is about, so read them for intent, not for a growth formula.
Sort into four types
Branded, campaign, category and community tags each reveal something different about a competitor's plans.
Category tags show positioning
The segments a rival tags consistently are the ones they want to be found under, and may lead their homepage.
Campaign tags give you dates
First and last use of a burst tag mark a campaign window you can match against their ads and site.
Adjust for the rule change
A drop in hashtag count after the cap is the platform, not a change in competitor strategy.
