Meta Ads in fall 2026: location fees, attribution, API versions, what changes for your accounts

This year, Meta changed what an impression costs, how a conversion is counted and the tools that read your accounts, all at once. Taken one by one, these changes look technical. Put together, they can move a CPA even though nothing changed in the campaigns. Here is how I read them, and what I would check first.

How are Meta location fees calculated?

Meta adds a location fee to the cost of ads delivered in six countries: Austria, France, Italy, Spain, Turkey and the United Kingdom. The rates are published on Meta's help page: 3%↗ for France, 3%↗ for Italy, 3%↗ for Spain, 5%↗ for Austria, 5%↗ for Turkey and 2%↗ for the UK. The full table is on the Meta location fees by country page.

The principle fits in one line: the fee depends on where your audience is located and where ad impressions are delivered, not on where your business is based. It sits outside the campaign budget and appears as a separate line on the invoice↗. A French business delivering ads in the UK therefore pays the UK rate, not the French one. The scope is broad: the fee applies to every ad format, including WhatsApp click to message campaigns and marketing messages invoiced together with ads, but not to other paid WhatsApp messages. Finally, VAT is calculated on the total (ad delivery cost plus location fee)↗.

One point remains unclear: Meta's page gives no effective date. The July 1, 2026 date comes from the press↗.

What is the impact on CPM and CPA?

According to Meta's help page, the campaign budget does not cover these fees: spend stays the same and the fee is added after delivery, so the amount invoiced can exceed the budget↗. A CPM or CPA computed from campaign spend therefore does not include the fees (check column by column in your account). By calculation, the real cost of a conversion in France is that CPA plus 3%↗, before VAT.

Two practical consequences. First, a CPA or ROAS target set before the summer has become harder to hit, for the same performance in Ads Manager. Second, a multi-country campaign can no longer be compared on displayed CPA: each country needs its own rate added. For an agency that rebills media spend, the fee line has to show up somewhere on the client invoice.

Why did click-through attribution change?

According to the agency AdsUploader, Meta has only counted link clicks in click-through attribution since March 2026↗. Other actions (non-link clicks, video plays) fall under "engage-through", a one-day window that Meta defines on its help page about attribution models, adding that some accounts may still use the earlier versions during the rollout↗.

The March 2026 date comes only from that agency. The likely consequence: click-through conversions can drop while actual sales do not. Before cutting a campaign whose CPA is rising, I would add the engage-through column to the report and compare the total over the same period.

What is the creative diversity rating for?

Meta now rates each ad set Low, Medium or High based on the visual and thematic variety of its creatives. According to an agency, the rating appeared in Ads Manager on August 26, 2026↗. No Meta help page documenting it was found at the time of checking, and the agency describes it as estimated and in development.

I would treat it as a signal, not a target. A Low rating mostly says the algorithm sees the same idea several times in different packaging. The useful response is genuinely different concepts (angle, format, proof), not color variants.

Which Marketing API and Graph API versions remain available?

The schedule is tight this fall:

• Marketing API v24.0 stops working after October 6, 2026↗, while Graph API v24.0 remains available until February 18, 2028↗;
• on October 27, 2026, several removals introduced in v26 (Commerce Order Management endpoints, estimated delivery fields, the story value of the Messenger Stories placement, poll ad creation, some protocol parameters) apply to all remaining versions of both APIs, while others, such as the Instagram Explore placement, are described as starting with v26.0 only↗;
• Graph API v21.0 will be removed on January 21, 2027↗.

The trap is the double schedule: a connector can keep reading a Facebook page and, on the same day, stop pulling ad spend. These changes concern API calls: manual use of Ads Manager is not, in principle, targeted, but dashboards, data warehouses and in-house scripts are. Details are in the news item on v26 removals extended to all versions.

What does the spend transparency rule change for agencies?

Policy 10.6.a of Meta's developer policies takes effect on February 3, 2027↗. It targets ad-buying solutions: agencies, resellers and tools that buy Meta ads on behalf of an advertiser. On the advertiser's request, they must disclose the Meta spend separately from their fees, their fee structure and the campaign configuration.

For an advertiser, it is a new right to use. For an agency that takes an undisclosed margin on media spend, it is a model to rethink before the deadline. I cover it in the news item on the 10.6.a spend transparency rule.

What does the US settlement on minors require?

A court settlement between Meta and 29 US states, approved by a federal judge on August 26, 2026, requires default settings for teen accounts, including a two-hour daily access limit and a block from midnight to 6 a.m., according to the law firm Hunton Andrews Kurth. The same firm mentions a one-year period after the settlement takes effect for an age-assurance framework, without giving an effective date↗. The agency AdsUploader, for its part, puts the deadline for the default settings at February 27, 2027↗. The two sources do not overlap: the February 27, 2027 date appears only in the agency's post.

The law firm does not tie the settlement to ad delivery: the link to campaigns is the agency's reading. If your ads target teenagers in the United States, it is a point to watch, not an established change in delivery. Until Meta communicates about ads, I would not build early 2027 forecasts for that segment on that single date.
