Your July reach numbers look different. Your Media Views figure doesn't map to anything in your historical reports. Someone on your team has asked why ROAS looks off compared to Q1.
Before you touch anything in your campaigns: Meta changed what these metrics measure on June 15. July is the first full calendar month you're operating entirely under the new system — and none of your pre-June 15 benchmarks apply.
What Meta actually changed
Meta retired a set of legacy metrics from its Graph API and Marketing API on June 15, 2026. The deprecated list includes Post and Page Reach, Video Impressions, Story impressions, format-specific impression breakdowns, and 3-second video viewer counts.
These were replaced with a unified views-and-viewers model: Media Views and Media Viewers. Reach is now Unique Views. Impressions are now Media Views.
The names are close enough that most advertisers assumed cosmetic renames. They are not. The underlying event definition changed.
Impressions counted an ad being delivered — pushed to a device regardless of whether it actually rendered. Media Views count an ad being visually rendered — the user's device displayed it on screen. A background tab, a feed position the user scrolled past before the content loaded, an ad served but never seen: these counted as impressions. The same scenario may not count as a Media View.
Meanwhile, Media Views can include repeat exposures from the same person, depending on content type. Impressions worked on a one-per-serve basis. The result is that your numbers will look different from comparable periods in Q1 — not because delivery changed, but because the definition of what gets counted changed.
The paid/organic breakdown is gone
Unique Views — the replacement for what used to be Reach — no longer separates paid and organic delivery. According to Social Media Today, which covered Meta's Marketing API overhaul, the new framework presents a combined total across both surfaces. There is no breakdown column in the standard Ads Manager interface.
This affects any account running concurrent organic posting and paid campaigns on the same Pages. If your brand posts frequently, your Unique Views number blends both streams. A lower number than your old Reach figure could mean paid delivery dropped — or it could mean you posted less organic content this week. You cannot tell from the native report.
For brands comparing CPM across periods, this is a structural problem. Your denominator changed in a way you didn't control and cannot reverse inside the platform.
How this shows up in your reports right now
Third-party analytics tools connecting to Meta's Graph API were pulling field names that stopped returning data after June 15. Platforms that had not migrated their connectors to the new schema by early July showed gaps, blanks, or an apparent data cliff around mid-June. If you're seeing that in your reporting tool, this is the cause.
The practical effect: any dashboard comparing post-June 15 Media Views data to pre-June 15 Impressions data in the same trend line is mixing two different measurement methodologies. The chart is not wrong because your campaigns changed. It's wrong because the metric changed mid-period.
What to do with this
Treat June 15 as a hard break in your historical data series. Any trend line that crosses that date is unreliable by definition. Build your July benchmarks from July 1 data and compare forward from there — week-over-week within the new model is clean data. Month-over-month against Q1 is not.
Check whether your reporting tool has published a Q2 2026 migration notice for its Meta connector. Look specifically for confirmation that it's pulling Media Views, Media Viewers, and Unique Views rather than the deprecated fields.
For actual campaign performance — Smart Bidding optimization, conversion data, CAPI signals — nothing about the metric change affected how Meta's algorithm makes decisions. The auction didn't move. What moved was the reporting layer above it. If your CAPI coverage is healthy and your conversion data is feeding in correctly, your campaigns are most likely performing exactly as they were in May.
If you want a clean read on where your Meta account's conversion signal quality actually stands right now, the free audit at Gromerce checks CAPI coverage, Event Match Quality, and attribution setup in a few minutes — independent of what the reach columns say.
The metrics changed. Your performance probably didn't. Make sure you know which one is the problem before you start solving it.
