What this Microsoft ad library is
1,467 ads from 388 advertisers, read from Microsoft’s public ad library. Each card carries the ad’s title, description and display URL, and, where the ad had one, the creative Microsoft published with it. Microsoft calls this network Microsoft Advertising; most people searching for it call it Bing Ads.
The wall opens on growth-stage companies rather than on multinationals, because that is who a startup marketer is actually researching: Grammarly, Anthropic, GitLab, Canva, Framer, Descript, Ahrefs, Harvey, Legora, Cartesia, beehiiv, Duda, Webflow, Wistia, Toast and Samsara all run here. It is a short list on purpose, and the reason is worth knowing: most venture-backed companies buy Google and Meta and never touch Bing, so the growth roster on this platform is a couple of dozen names against a few hundred established advertisers.
Microsoft Advertising is a search network first, and about one ad in six here has no image at all — it is a headline, two lines of description and a display domain, which is the entire unit. Those render on this page the way a search results page renders them, because that is what they are. Reading a column of them is the fastest copy lesson in paid search: the good ones name the thing and the differentiator inside sixty characters and stop.
The image ads are the Audience Network side of the same account — native placements across MSN, Outlook.com, Edge and partner sites. What is striking, reading the two side by side, is how many advertisers run near-identical copy in both and let the image do nothing. The ones that work treat the native placement as a feed unit, not as a search ad with a picture stapled to it.
Bing’s audience is the reason the advertiser list here looks the way it does. It skews older, more desktop, more Windows and more workplace than Google’s, and the roster reflects it: enterprise software, banks, insurers, travel, home improvement, and a long tail of European retail. It is a cheaper auction than Google for most of those terms, which is the whole argument for running it.
The library is also a reminder of what the platform does not tell you. Google’s Transparency Center at least gives a first-shown and last-shown date and an impression band; Microsoft’s gives neither, so nothing on this page can say how long an ad ran or how many people saw it, and nothing here estimates it.
Shopping ads are the third unit and the most visually distinct: a product image from the merchant’s own feed, which is why some creatives here sit on a retailer CDN rather than on Microsoft’s. They are the clearest illustration that a Microsoft campaign is usually a mirror of a Google one, exported and re-bid.

Where these ads come from
These come from Microsoft’s ad library at adlibrary.ads.microsoft.com, which exists because Bing is a designated Very Large Online Platform under the EU Digital Services Act. Two consequences worth stating. The delivery is EU/EEA — an advertiser’s own country in the library is where the company is, not where the ad ran. And Microsoft publishes markedly less per ad than Snap or TikTok do: an ad id, an advertiser, a title, a description, a display URL, a destination and its image assets, and nothing else. No dates, no impressions, no spend, no call-to-action label, and no video — every asset in the library is a still.
- Every creative is a copy, not a hotlink.All 1,467 creatives were downloaded, checked against their own magic bytes and copied to our CDN before this page shipped. A creative that could not be copied was dropped rather than published as a tile that would go blank when the platform expired its URL.
- No spend, impressions or conversions.Microsoft publishes none of them for commercial advertising, and nothing on this page estimates them. A field absent on a card means the source did not publish it.
- Each card links to the page it came from.The creative viewer names the source for every ad, so any claim on this page can be checked against the record it was read from.
- Read on one date.This library was read on September 15, 2026. It is a snapshot of what Microsoft published that day, not a live feed.
Frequently asked questions
Does Microsoft have an ad library?
Yes, at adlibrary.ads.microsoft.com. It is Microsoft’s EU Digital Services Act disclosure for ads on Bing and the Microsoft Advertising network, and it is the source this page reads. It needs no login.
Is Microsoft Advertising the same as Bing Ads?
Yes. Bing Ads was renamed Microsoft Advertising in 2019. The network reaches Bing, Yahoo, DuckDuckGo, AOL and Ecosia search, plus a native audience network across MSN, Outlook.com, Edge and partner sites.
Why do some ads have no image?
Because a search text ad has none. It is a headline, a description and a display URL, and roughly one ad in six in this library is that unit. They are shown here the way a search results page shows them rather than being left out.
Can I see what a Microsoft ad cost or how long it ran?
No. Microsoft’s library publishes no dates, no impressions and no spend — less than Meta, Google, LinkedIn, Snap or TikTok publish. Nothing on this page estimates them.
Are these ads from the US or the EU?
The delivery is EU/EEA, because the library is a Digital Services Act obligation. Where the library names a country for an advertiser, that is where the advertiser is registered, not where the ad was served.
Do I need a Microsoft Advertising account?
No Microsoft account and no Sprites account. The first rows are open; one email address opens the rest.
