A familiar message lands in agency inboxes: "Our Facebook reach number is gone, and the new figure looks nothing like last year. What happened?" Nothing is broken on the client's Page. Meta retired the metrics that used to power reach and impressions for Facebook Pages and replaced them with views, viewers and follows. Any report that still tries to pull the old numbers either shows a gap or quietly stops updating.
This guide explains exactly which metrics changed and when, what views measure compared with reach and impressions, why the old and new numbers cannot sit on the same trend line, and how to rebuild the organic Facebook part of a client report so it reads clearly from the first month. It finishes with wording you can reuse when a client asks about the change.
Key takeaways
page_impressions_unique and post_impressions_unique, the basis of Page reach.page_impressions, post_impressions and page_fans followed, replaced by page_media_view, post_media_view and page_follows.Meta removed the reach and impressions metrics from the Page Insights API in two waves during 2025 and pointed developers to view based metrics instead. The first wave, on June 15, 2025, covered the unique impression metrics that reporting tools used for Page and post reach. The second, on November 15, 2025, covered total impressions and the old Page fans count. Meta's list of deprecated Page Insights metrics names a replacement for each one.
| Old metric | Deprecated | Replacement |
|---|---|---|
page_impressions_unique (Page reach) | June 15, 2025 | page_total_media_view_unique |
post_impressions_unique (post reach) | June 15, 2025 | post_total_media_view_unique |
page_impressions | November 15, 2025 | page_media_view |
post_impressions | November 15, 2025 | post_media_view |
page_fans | November 15, 2025 | page_follows |
Meta announced the November change on its developer blog in August 2025, giving 90 days of notice and explaining that it wanted the API to match what the Facebook app and Meta Business Suite already show. The same Page Insights API update states that a call for a deprecated metric now returns an invalid metric error. That is why some dashboards went blank rather than showing a smaller number: the data source simply stopped answering.
The paid side has its own set of changes, so keep the two apart in your reporting. Organic Page numbers belong in the social section, while campaign results for Facebook and Instagram ads belong in a separate paid report with its own metrics and attribution notes.
Impressions counted how many times content was shown, reach counted how many unique people saw it, and views count how many times content was played or displayed. The difference sounds small, but it changes the size and the meaning of the number in your report.
page_media_view as the number of times content was played or displayed, and says that content includes videos, posts, stories and ads. Repeat views count.page_total_media_view_unique counts unique media viewers for a Page. This is the closest thing to the old reach figure.page_follows is the follower count, calculated as follows minus unfollows over the lifetime of the Page.Two details matter for agencies. First, the views description includes ads, so a Page that also runs campaigns can show a views total that mixes paid and organic. Meta's deprecation notes point to an is_from_ads breakdown as the way to separate them, and an is_from_followers breakdown for views from existing followers. Second, every definition above comes from Meta's Page Insights metric reference, which is the page to check if a client or a colleague questions a number.
Views and reach measure different things, and Meta does not publish any formula that converts one into the other. Views count displays, including repeats; reach counted people. A month with 40,000 views is not "up" on a month with 15,000 reach, because the two numbers were never on the same scale.
Even viewers, the closest match, is a new metric with its own counting rules. It may land near the old reach figure for some Pages and far from it for others, depending on how much video, how many stories and how much paid activity the Page has. Putting old reach and new viewers on one line chart invites the client to read a jump or a drop that is only a change of definition.
History is the other problem. Once a metric is deprecated, the API returns an error for it, so a reporting tool cannot backfill months of views for the period when it was collecting reach. In practice you will have a clean series of the old metric that stops, and a clean series of the new one that starts. Treat them as two separate series, not one.
The same lesson applies across platforms. When a platform renames or redefines a core metric, the honest report starts a new baseline and says so, rather than stitching two definitions together and hoping nobody notices.
Build the section around five figures that the current API supports, each shown against the previous period: views, viewers, follows, engagement and top posts. That keeps it short, comparable month to month, and honest about what is being measured.
Add one line under the chart that marks the switch, such as "Views replaced reach and impressions in Meta's Page Insights data in 2025; figures before this point are not comparable." Then write a two or three sentence comment on what drove the month: a video that travelled, a quiet posting week, or a campaign that lifted paid views.
If you run organic social media reporting in AgencyReportr, the Social report already uses views and follows for Facebook Pages, alongside engagement, top posts and audience. Instagram sits in the same report, and so does YouTube channel performance reporting, which helps when a client's video strategy spans several platforms. Each report opens with an AI-written summary of the period, which gives you a starting point for the commentary.
Explain it once, early, in plain words: Meta changed how it counts, the new number is views, and it starts a new baseline. Clients rarely mind a definition change. What erodes trust is discovering it themselves and wondering whether the agency noticed.
Wording you can reuse: "Meta has replaced the old reach and impressions figures for Facebook Pages with views and viewers. Views count every time your content is shown, including repeat views, so the numbers are larger and are not comparable with earlier reports. From this month we track views, viewers, follows and engagement, and we will compare each month with the one before."
Send that note before the first report with the new metrics, then repeat a one line version on the report itself. Keep the label consistent across every client so your team does not have to explain it differently each time, and include it in branded reports for every client rather than in a one-off email that gets lost.
Finally, shift the conversation from size to direction. A client who used to celebrate a big reach number will get more from seeing which posts earned views and follows this month, and whether that is rising. Delivered on a fixed schedule through emailed monthly PDF reports, that trend becomes the thing the client looks for, and the old reach figure stops being missed.

Meta deprecated the unique impression metrics behind Page and post reach, page_impressions_unique and post_impressions_unique, on June 15, 2025. On November 15, 2025 it also deprecated page_impressions, post_impressions and page_fans. Meta now reports views, viewers and follows instead.
Reach counted unique people who saw your content. Views count every time content was played or displayed, so one person can add several views. The closest replacement for reach is the unique viewers metric, page_total_media_view_unique for a Page and post_total_media_view_unique for a post.
No. They measure different things and Meta does not publish a way to convert one into the other. Start a new baseline from the first month you report views, mark the switch on the chart, and compare views only with earlier views.
page_follows. Meta describes it as the number of followers of a Facebook Page or profile, calculated as follows minus unfollows over the lifetime of the Page. Report it as the follower total and show the monthly change next to it.
They can. Meta's description of page_media_view says the content counted includes videos, posts, stories and ads. Meta points to the is_from_ads breakdown for separating paid views, so use it when you want an organic only figure.
