The Microsoft Ad Library is Microsoft's public record of ads shown on Bing and Microsoft's network in Europe. B2B buyers search at work on desktop, and plenty of them use Bing, so it's a sharp read on who's paying to reach them. Revnu pulls the ads for you and turns them into your own search campaign.

## What the Microsoft Ad Library shows

Search by advertiser or keyword to see ads shown in Europe, with the ad copy, the advertiser behind it and when it ran.

## What Revnu pulls

Revnu's scrapers pull ads from the Microsoft Ad Library by keyword or advertiser, then Revnu reads each ad and the page it links to.

## What Revnu does with it

### Find who's advertising on your keywords

> Search the Microsoft Ad Library for "[your category]" and "[the problem you solve]". List every advertiser, their headlines and where each ad sends people.

### Read a competitor's search ads

> Pull [competitor]'s ads from the Microsoft Ad Library. What do they promise, and how is it different from their Google ads?

### Turn advertisers into leads

> Find companies advertising on Bing for "[a keyword]". Add the ones that fit my ideal customer to Leads, with the person who runs marketing.

### Build your own Microsoft Search campaign

> Write a Microsoft Search campaign for us that answers the gap you found. Pick the keywords and negatives, write the ads, and save it as a paused draft.

With Microsoft Ads connected, Revnu builds Search campaigns as paused drafts for you to approve. When Google Ads is connected too, it picks keywords from Google's keyword data. See [connect Microsoft Ads](/docs/connect-microsoft-ads).

## Frequently asked questions

### Can Revnu see my competitors' Bing ads?

Yes. Revnu pulls their ads from the Microsoft Ad Library, Microsoft's public record of ads shown in Europe, and reads the copy and the pages they link to.

### Does the Microsoft Ad Library show ads outside Europe?

The library covers ads shown in Europe. Many advertisers run the same search ads in every market, so it's still a strong guide to how a competitor sells on Bing.

### Do I need Microsoft Ads connected to research ads?

No. The Microsoft Ad Library is public, so Revnu can research it on any account. Connect Microsoft Ads when you want Revnu to build your own Search campaign.

### Should I research Google and Microsoft ads together?

Yes. Ask Revnu to compare a competitor's ads in both, and it shows where their message matches and where it differs. See [the Google Ads Transparency Center](/docs/ads-library-google).
