24 Google Ads feature families were later re-implemented elsewhere — 28 adoption events in official documentation, nearly all at Microsoft
Asked:“How many features is google ads were copied in other ad systems from 2015 to 2025” — with the correction: “No, you have to do your own research, do not use any public researches. Look at the documentation of each ad system you know.”
This audit reads only first-party pages: official Google Ads blogs and documentation against the official product blogs of Microsoft Advertising, Amazon Ads, TikTok for Business and Pinterest, 2015–2025. Under a functional-equivalence rule — Google documented first; a later official page describes substantially the same advertiser input, mechanism and outcome — “copied” means a documented later near-equivalent, not proven intent or legal copying.
24 distinct Google feature families · 28 platform adoption events · 24 Microsoft Advertising · 4 other-platform events (Amazon 1, TikTok 1, Pinterest 2)
The audit matrix: who documented what, and when
Each row is one Google feature family. Cell colour = years between Google’s official documentation and the later platform’s. Hover any cell for the exact dates and sources.
28 adoption events on one timeline
One dot per official later-platform document, 2021–2025. Colour = platform. Hover for the family and date.
What the matrix cannot say alone
Microsoft’s densest adoption window was 2021–2023, when Customer Match, Similar Audiences, Promotion Extensions, Portfolio bid strategies and Dynamic Search Ads all reached official Microsoft documentation — for example the May 2021
about.ads.microsoft.com update carrying four of the 24 families.
The oldest gap in the set is Campaign Experiments: Google documented drafts and experiments on 2016-02-18 (
blog.google), Microsoft documented its equivalent on 2021-02-02 — a five-year lag.

Method and limitations
This is a first-party-documentation comparison, not an exhaustive legal or forensic determination. Inclusion required: (1) official Google documentation establishing that Google had the feature first; (2) an official later-platform document dated 2015–2025 describing substantially the same advertiser input, mechanism and campaign outcome; (3) each Google family counted once in the 24, each later-platform implementation once in the 28. Excluded: third-party claims, Google-import utilities, renames and deprecations, generic ad formats without distinctive functional overlap, and items whose order could not be established from official pages. Documentation establishes chronology and functional equivalence only — never a platform’s intent. Where an exact Google launch day is not on an official page, the earliest official documentation date is shown as “official documentation found by [year]”.
Data: 391 rows of official-domain documentation — Google Ads blog and documentation pages, Microsoft Advertising product-update posts, and Amazon Ads, TikTok for Business and Pinterest Business announcements — collected for this audit. Dates are the publication dates of the official pages; a date measures when a page documented the feature, not necessarily the launch day. Duplicate URLs, import tools and non-equivalent features were cut for the 24-family view.
