Microsoft Ad Library — see their Bing ads

What Microsoft's Ad Library covers

Microsoft Ad Library is a free public archive of ads shown on Bing in European Union and European Economic Area countries. An advertiser can be based anywhere; it is the location of the impressions that determines whether the ads appear.

It is not a worldwide account of a competitor's Microsoft advertising. An empty result does not prove that a company has stopped advertising in the US, UK, South Africa or another market outside the EU/EEA.

Find the right advertiser

Search the advertiser name or words from the ad copy. Check the returned advertiser identity before reading its ads. A verified advertiser may group more than one advertising account under the same identity.

Once you have found the advertiser, keep their advertiser URL. For example, adlibrary.ads.microsoft.com/advertiser/4295406264 identifies Pam Golding Properties. Paste that URL into Rival Ads to track the same identity, then choose the EU/EEA countries you want to monitor.

Read the evidence with its limits

Microsoft publishes representative ad copy, destination links, available creative assets, first/last shown dates and EU/EEA impression ranges. Dynamic ads can have multiple variations; the version shown is a representative creative, not a record of every combination served.

Microsoft may publish impressions 1–3 days later. A last-shown date is the latest eligible impression reported by the archive, not confirmation that a campaign was switched off. Rival Ads checks a seven-day activity window separately in each monitored country. The ad detail dates describe the whole EU/EEA, not country-specific first or last impressions.

The archive does not reveal a competitor's spend, clicks or conversions. Impression ranges and targeting information help explain where an ad appeared; they do not establish its profitability.
