About Microsoft Advertising
Microsoft Advertising, formerly Bing Ads, is Microsoft's ad platform, serving ads on Bing and across its partner network.
Its Universal Event Tracking tag, loaded from bat.bing.com, reports page visits and conversions back to advertisers running campaigns on Microsoft Advertising, similar in role to Google Ads or the Meta Pixel.
A Microsoft account's privacy dashboard lets a user limit ad personalization, and Microsoft Advertising participates in the Network Advertising Initiative's opt-out program.

Understanding this page
- What the tracker categories mean
What "advertising," "analytics," "social," "consent" and the rest actually mean for a company or a cookie, and how CookieTosser decides which one applies.
- First-party vs third-party cookies (and why "first-party" still tracks you)
What the distinction actually means technically, why browsers only block one of the two, and how CNAME cloaking, server-side tagging and cookies like _ga let sites keep tracking under their own domain.
- How to block or limit trackers
Browser privacy settings, content blockers, Global Privacy Control and clearing cookies compared honestly — what each one actually stops, what it doesn't, and what it costs you in return.
