How Far Back Does the Meta Ad Library Go? (2026 Answer)

Commercial ads: 7 years in theory, 2022+ reliably in practice. Political/issue/housing/employment/credit ads: back to 2018 when the library launched.

How far back does the Meta Ad Library go?

TL;DR: Two answers depending on ad type. Political, issues, housing, employment, and credit ads are retained for 7 years minimum and visible back to 2018 (when the library launched). Commercial ads have a shorter effective history — officially 7 years, but reliably visible from mid-2022 onward. In practice, assume you can see 3–4 years of commercial ads, but anything older may be missing.

Why the answer depends on ad category

Meta was required by regulators in multiple jurisdictions (EU, US, UK) to create the Ad Library for regulated categories: political/issue ads, housing ads, employment ads, and credit ads. These face the longest retention requirements — 7 years in the US for regulated categories, and Meta preserves them beyond that window in many cases.

For commercial ads (the typical eCommerce, DTC, SaaS advertiser), the Ad Library was extended later and retention rules are less strict. Officially Meta states 7 years of retention; in practice, the oldest commercial ads you can reliably find date to around mid-2022, with patchy coverage beyond that.

What this means for competitor research

For most reverse-engineering work, the 2022+ window is more than enough — the vast majority of creative tactics you’re evaluating are recent anyway, and older ads reflect a different platform, different UI, and often different creative norms.

For longer historical analysis (e.g. “how has this brand’s creative strategy evolved over 5 years”), the commercial Ad Library is less reliable. You may need to supplement with:

  • The Wayback Machine (archive.org) — occasional snapshots of brand Facebook pages
  • Third-party archives (Foreplay, Motion, AdSpyder) that cache Ad Library data
  • Brand’s own announcements and press coverage for campaign timelines

A tactical note

The start date shown on any individual ad result is the date the ad was first published, not the date it was indexed. An ad showing a start date of “April 2023” was actually running in April 2023 — Meta doesn’t retroactively add ads to the library.

This matters because ad longevity (e.g. an ad running continuously since April 2023) is a strong signal the ad is actually performing. The library’s retention window is wide enough that longevity claims are reliable for any ad with a visible start date.

Key takeaways

  • Political/issue/housing/employment/credit ads: back to 2018 (when the library launched).
  • Commercial ads: officially 7 years; reliably 2022+ in practice.
  • For most reverse-engineering use cases, 3–4 years of visible history is more than enough.
  • For older data, supplement with archive tools or third-party ad intelligence platforms.
