Instagram advertising is no longer one feed and one image format. Feed, Stories, and Reels now behave like different channels, and Meta’s public library only answers part of the competitive-research question.
The hard part is not catching a competitor’s ad in your own feed. It is building a reliable view across advertisers, markets, formats, and time.
Meta has kept changing how ads are selected and delivered on Instagram. In January 2026, the company said a new run-time model operating across Instagram Feed, Stories, and Reels lifted conversion rates by 3% in Q4 2025. In the same update, Meta reported that improvements to its ads-ranking systems produced a conversion gain of more than 1% on Instagram.
Those are Meta’s aggregate platform results, not a guarantee for every advertiser. But they explain why studying one placement or one creative format gives you an incomplete picture.
This piece covers three things: why Instagram creative research has become more complex, what Meta’s Ad Library actually reveals, and how to turn public ad evidence into a practical pre-launch process.
Why Instagram ads still matter
For creative teams, the important change is structural. Instagram is now a set of different attention environments:
- Feed gives users more context. Images, videos, and carousels compete alongside organic posts.
- Stories use a vertical, full-screen sequence where the opening frame and immediate message carry the weight.
- Reels place ads inside a sound-led short-video experience, where native pacing and vertical composition matter.
That means “an Instagram ad” is not one reusable unit. A competitor may keep the same offer but change the hook, crop, pacing, caption density, audio, or call to action for each placement.
The useful question, then, is not simply “What ad are they running?” It is “How are they adapting the same commercial idea across Instagram surfaces?”
Meta’s Reels guidance says vertical 9:16 video with audio and key messages inside the safe zone produced 34.5% lower cost per result than image ads in a meta-analysis of 15 Reels-only split tests. That is evidence from a defined Meta study, not a universal benchmark for every account, market, or objective.
Why Instagram creative works differently across placements
Feed ads can behave like visual storefronts. They have room for a product image, social proof, a longer caption, and a carousel that reveals details in sequence.
Stories and Reels operate under tighter attention constraints. The first seconds, vertical framing, readable overlays, and an immediate reason to keep watching become more important.
Meta describes Reels ads as immersive, mobile-first placements and recommends creative built for 9:16 video, audio, and the Reels safe zone. It also notes that Reels can be entered from the dedicated Reels tab, Explore, or an in-feed unit. The same video may be encountered from different browsing contexts even within one placement family.
For competitor research, this creates a common mistake: judging a creative without its placement context.
A polished square image may be right for Feed but weak evidence for a Reels strategy. A fast UGC-style video may look rough in isolation but fit the language of Reels much better. Compare like with like before you borrow a pattern for your own brief.
The catch: Meta Ad Library is a transparency tool
Instagram ads are not hidden. Meta Ad Library lets anyone search ads currently running across Meta technologies by keyword or advertiser.
Meta says an ad normally appears in the library within 24 hours of receiving its first impression, and later changes are reflected within 24 hours.
Retention rules depend on the type and location of the ad:
- Meta keeps social-issue, election, and political ads for seven years.
- Ads delivered in the European Union are available for one year.
- Qualifying UK ads are also available for one year.
- For ordinary commercial ads outside those scopes, the public library is mainly a view of ads that are currently active.
That is valuable for transparency, but it does not answer every creative-strategy question. A marketer may still need to compare inactive and active creatives, group similar assets, sort by first or last observation, separate placements, compare markets, or search for visual patterns across many advertisers.
Do not treat Meta Ad Library as a source of a competitor’s private performance. For ordinary commercial ads, exact spend, ROAS, conversions, and detailed targeting are not generally public. Additional spend, reach, and demographic fields apply only to specific transparency categories and regions, not to every Instagram ad worldwide.
How to research Instagram ads at scale
Third-party ad databases organize public creative records for marketing research.
In BigSpy, you can select Instagram as the network, search by advertiser or keyword, and narrow results using filters such as country or region, language, time range, creative format, and industry context.
BigSpy’s Ad Library workflow also supports sorting by signals such as:
- Estimated impressions
- Latest creatives
- Last seen date
- Running days
- Related ads
- Popularity
- Available engagement metrics
Feature Search and Visual Search can be used to look for similar scenes, products, layouts, or video styles rather than relying on an exact text match.
BigSpy Instagram coverage: what you can actually see
That’s the gap third-party ad databases fill. BigSpy indexes Instagram creatives independently of the platform and surfaces the same categories of information that the channel’s own transparency terms permit to be public:
- the advertiser and domain behind each creative
- the creative itself, and which format it uses
- estimated impressions
- when it was first seen, and when it was last seen
- placement tags
You’re not reading leaked data. You’re reading what’s permitted to be public, in an interface nobody at Meta or Instagram had a reason to build.
BigSpy’s Instagram coverage is scoped to ecommerce and collected daily across 70+ countries and regions. The count changes every day, and the interface shows multiple views of the same query — related ads, default deduplication, and strict ad deduplication — because each view answers a different question.
Good enough to answer the question you actually have before committing a budget line: what is already running in my category, and for how long has it been running?
Two things to hold onto before you draw conclusions from it.
A long-running creative is not proof of profitability. Advertisers keep campaigns alive for reasons that have nothing to do with return — brand budgets, agency retainers, contractual commitments. Treat longevity as a prompt to look closer, not as a verdict.
You cannot see spend, ROAS, or targeting. Those fields are private. Any tool claiming to show them is telling you something about the reliability of its other claims.
BigSpy should be used to create hypotheses for original testing, not to label a competitor’s creative a guaranteed winner.
Using Instagram ad research before you launch
Five questions make the research useful before you commit budget.
1. Who is active in the category?
Search the product, category, advertiser, app, or brand terms relevant to your market. Separate direct competitors from broader creative references.
2. Which placements and formats do they appear to prioritize?
Compare Feed-style images and carousels with vertical Stories and Reels video. Do not assume one asset represents the advertiser’s entire Instagram approach.
3. Which hooks and offers repeat?
Record the opening promise, product demonstration, proof, price framing, promotion, and call to action. Repetition across multiple creatives is more informative than a single isolated ad.
4. How does the creative change over time?
Compare first and last seen dates, new variants, and recurring concepts. Use longevity as a reason to inspect the idea, not as proof of ROAS.
5. What can your team test originally?
Translate observed patterns into a new brief for your own product, customer, evidence, and brand voice. Do not copy a competitor’s protected creative.
The outcome should be a short test plan: one audience problem, several original hooks, a placement-specific format, a clear offer, and a measurement plan based on your own campaign data.
Instagram ad research FAQ
Does Instagram have an official ad library?
Yes. Instagram ads are included in Meta Ad Library, which lets people search ads currently running across Meta technologies. Historical availability and additional transparency fields depend on the ad category and the region where the ad was delivered.
Can I see a competitor’s Instagram ad spend or ROAS?
Not for ordinary commercial ads worldwide. Exact spend, conversions, ROAS, and detailed targeting are private campaign data. Meta publishes additional ranges and demographic information only for defined transparency categories and regions.
What is the difference between Meta Ad Library and BigSpy?
Meta Ad Library is the platform’s official transparency tool. BigSpy is an independent advertising-research database that organizes collected creative records with additional search, filtering, sorting, historical research, and similar-creative workflows.
Can BigSpy find Instagram ads that are no longer active?
BigSpy retains historical records collected by its monitoring system, so eligible inactive creatives may remain available for research. Coverage depends on when and whether a record was collected; it should not be described as a complete archive of every Instagram ad ever delivered.
How many Instagram ads are in BigSpy?
BigSpy does not publish a single fixed total. Query results change daily and depend on filters such as market, language, format, time range, and deduplication mode. The interface shows related ads, default deduplication, and strict ad deduplication as separate views because they represent different result scopes. Treat any filtered count as a research signal, not an all-time total of unique Instagram creatives or advertisers.
What should I compare when researching Instagram ads?
Compare advertisers, markets, placements, formats, hooks, offers, calls to action, first and last seen dates, and repeated creative patterns. Use these observations to design original tests, then judge performance with your own campaign results.
Research Instagram creatives with more context
Search Instagram ads by advertiser or keyword, apply market and creative filters, and turn visible patterns into an original test brief.
