LinkedIn Ad Library: How to Find and Use Competitor B2B Ads (2026)

The LinkedIn Ad Library is LinkedIn's free, public ad-transparency database, hosted at linkedin.com/ad-library. Like the Meta Ad Library and the Google Ads Transparency Center, it exists so anyone — competitors, journalists, researchers, regulators — can see the ads a company is running, without needing an account or any relationship with the advertiser. No LinkedIn login is required to search it.

According to LinkedIn's official help center, the library "includes ads that ran on LinkedIn after June 1, 2023," and "ads remain in Ad Library for one year after their last impression on LinkedIn." That two-part rule matters for research: there is a hard floor on history (nothing before June 2023) and a rolling window on the future (an ad disappears a year after it stops being served). The library is a moving picture of recent and active advertising, not a permanent archive.

For each ad, the library typically surfaces the creative itself (the image, video, document, or text), the ad format, the advertiser name, and the payer name (who funded it, which can differ from the brand). For ads shown to people in the European Union, LinkedIn discloses more — including an impression range and targeting parameters — to satisfy EU transparency rules. Ads classified as restricted may have certain details withheld for legal compliance.

In plain terms: the LinkedIn Ad Library is the single best free window into how B2B companies advertise on the platform where most B2B advertising happens. It is the LinkedIn-specific source that complements — not replaces — Meta and Google transparency for a complete competitive picture.

Searching the LinkedIn Ad Library is fast and requires no account. The workflow mirrors how you'd use the Meta or Google libraries, with a few LinkedIn-specific filters.

Search by company. The most common research move is to look up a single competitor. Go to linkedin.com/ad-library and search the advertiser by name. You'll see the ad creatives that company has run on LinkedIn since June 1, 2023 and that are still within the one-year-after-last-impression window. This is the LinkedIn analogue of searching a brand in the Meta Ad Library.

Search by keyword or payer. Beyond a single brand, you can search by keyword to see how an entire category talks (e.g., "data observability" or "fractional CFO"), or by payer name to find ads funded by a specific entity — useful when an agency or parent company pays for a brand's ads.

Filter by country and date. Narrow results by country to see how messaging is localized, and by date range to study how a competitor's creative has evolved over recent quarters. Because ads carry recency metadata, date filtering is how you separate a competitor's current push from older, retired campaigns.

Read the EU extras. For ads delivered in the European Union, LinkedIn shows additional transparency data, including an impression range and targeting parameters. This is the closest the public library comes to revealing reach and audience — and it only appears for EU-served ads.

What you get back is the raw material of competitive analysis: every creative, by format, that a competitor is actively running. What the library does not hand you is the interpretation — which is the work the rest of this guide covers.

The three major ad libraries are complementary, not interchangeable. A competitor's full advertising footprint is split across them, so serious competitive research checks all three.

Coverage and scale. The Meta Ad Library is the broadest — it indexes ads from 8 million advertiser pages across Facebook and Instagram and is the default for consumer and DTC research. The Google Ads Transparency Center (launched 2023) spans Search, Display, and YouTube, the widest set of placements. The LinkedIn Ad Library is narrower by design — LinkedIn only — but that narrowness is the point for B2B: it's the one library where the audience is professionals, decision-makers, and buying committees.

History and retention. LinkedIn's window is the most explicitly bounded of the three: ads from after June 1, 2023, kept for one year after last impression. Meta retains political/issue ads far longer (seven years) but commercial ads only while active plus a short tail. Treat all three as recency-biased, not deep archives.

What each reveals. All three reliably show the creative, format, and advertiser. None reveals true spend or results for ordinary commercial ads. LinkedIn and Meta both expose extra detail (reach/impression ranges, targeting) specifically for EU-served and political/issue ads under transparency law; for everyday B2B commercial ads, you get the creative, not the performance.

The honest takeaway: if you sell to businesses, the LinkedIn Ad Library is indispensable and under-used. But B2B buyers also see ads on Meta and Google, so the complete Competitor Ad Map requires reading across platforms. That cross-platform read is exactly where a dedicated ad-intelligence tool saves hours — though, importantly, automation today (including Rival) covers Meta and Google, and LinkedIn remains a manual source.

The LinkedIn Ad Library has a clear, honest limit: it is a creative-transparency tool, not a performance-analytics tool. For ordinary commercial ads it shows you the ad, the format, the advertiser, and the payer — but it does not show spend, click-through rate, conversions, or audience size. (EU-served ads add an impression range and targeting parameters, the only partial exception.) You learn what a competitor is running, never directly whether it's working.

That limit is also why the library, on its own, doesn't change anything. Most teams open it, scroll a competitor's ads, think "interesting," and close the tab. The value is unlocked only when you do two things the library can't do for you:

• Analyze the creative systematically. Don't just look — score. Read every ad against a fixed rubric so the pattern becomes legible rather than a vague impression. Rival's 5-Layer Creative Teardown scores each ad across Hook, Format, Message, Proof, and Offer; run it on a competitor's LinkedIn ads by hand and the recurring strategy — their Ad Strategy Fingerprint — emerges.
• Map the gaps and act. Once you can see what a competitor always does, what they never do becomes obvious: the formats they skip, the proof they never show, the offers they don't make. That white space is a creative gap you can claim before they notice it.

This is the wedge no generic scraper fills: connecting what's in the library to a decision about your own next ad. The library is the input; the Intel-to-Creative workflow — analyze, find the gap, brief it, generate, ship — is the output. For Meta and Google, Rival runs that loop automatically; for LinkedIn, you run the same method manually using the library as your source.

The 5-Layer Creative Teardown is Rival's per-ad analysis method, and it is platform-agnostic — it works just as well on LinkedIn ads you review by hand as on the Meta and Google ads Rival scores automatically. Run each ad in the LinkedIn Ad Library through the five layers:

• Hook — the first three seconds or first line. What stops the scroll: a stat, a contrarian claim, a named pain, a visual pattern-break? B2B hooks lean on specificity and credibility.
• Format — single image, video, document/carousel, text, or thought-leader ad. LinkedIn's document and conversation formats are distinctive; note which a competitor leans on and which they ignore.
• Message — the core value proposition and the angle (ROI, speed, risk reduction, status, compliance, peer proof). List the recurring themes across the set.
• Proof — the evidence: customer logos, named case studies, metrics, analyst mentions, testimonials. B2B buying turns on proof, so its presence or absence is highly diagnostic.
• Offer — the call to action and the commitment level: demo, free trial, report download, webinar, "talk to sales." Note which intent levels they capture and which they leave open.

Score 10–20 of a competitor's ads this way and a pattern crystallizes — that aggregate is their Ad Strategy Fingerprint. A vendor that always hooks with a stat, always runs single-image ads, always sells "speed," always shows one logo wall, and always asks for a demo has told you exactly where it's strong and, by omission, where it's exposed.

The exposed dimensions are creative gaps — the building blocks of a Creative Gap Score. No video? A document angle never tried? Proof limited to logos with no quantified case study? Each absence is an opening. The method is identical to how you'd analyze a competitor's Facebook ads; only the source library changes. The difference on LinkedIn is that you supply the labor the automation otherwise would — which is entirely workable for the handful of competitors most B2B teams actually track.

To be completely clear: Rival does not scrape, pull, or automate the LinkedIn Ad Library. Rival's automated pipeline covers Meta (Facebook/Instagram) and Google only. Any guide that implies a tool silently mirrors LinkedIn's library is overselling — the LinkedIn Ad Library is something you use directly, for free, at linkedin.com/ad-library.

So how does Rival help a B2B team that also advertises on LinkedIn? In two honest ways:

1. It automates the Meta + Google half. Most B2B brands run on more than LinkedIn — they retarget on Meta, run Google Search against category keywords, and use YouTube. For that portion of a competitor's footprint, you enter a company name and Rival auto-discovers competitors, scrapes every active ad on Meta and Google, runs AI analysis (copy via GPT-5-nano, image via GPT-5-nano vision, video keyframes via ffmpeg), and produces an Ad Intelligence Report with an Ad Strategy Fingerprint, a Creative Gap Score, and a Competitor Ad Map — analyzing 100+ ads in minutes, not the hours a manual read takes.

2. It supplies the method for the LinkedIn half. The 5-Layer Creative Teardown and Creative Gap Score are frameworks, not features locked to one platform. Apply them by hand to the LinkedIn ads you pull from the library and you get the same structured read Rival produces for Meta and Google. And when you find a gap, Rival's Gap-Driven Generation can turn it into candidate image creatives (image-only today; video is a future wave) — generation grounded in a real competitive gap, which is faster and more targeted than briefing from a blank prompt, not a claim of higher click-through.

Rival's plans — Free $0 (1 competitor), Pro $19/mo (5 competitors), Team $49/mo (15 competitors) — price the automated Meta + Google analysis. The LinkedIn Ad Library stays free and manual, and this guide is how you get the most from it. For the broader intel-to-creative workflow, the principle is the same on every platform: research the gap, then fill it.
