Cyber Monday Ads: What 70,254 Meta Ads Say About Timing

On Monday 1 December 2025, Cyber Monday, 20,162 new Meta ads that mention Cyber Monday went live, according to Brandsearch's index of Meta ads. The same day, 24,373 new ads still said Black Friday, three days after Black Friday had ended.

Even on its own day, Cyber Monday got fewer new ads than the event it is supposed to follow. Across the whole 2025 season the gap is far wider, and the timing tells you most of what you need for 30 November 2026: on Meta, Cyber Monday works as the last day of a Black Friday campaign. A Cyber Monday ad launched on the Monday morning mostly gets Monday's audience.

Twenty-three Black Friday ads for every Cyber Monday ad

Between 1 September and 15 December 2025, the index holds 70,254 Meta ads whose copy mentions Cyber Monday, against 1,619,611 that mention Black Friday. That is 23 Black Friday ads for each Cyber Monday ad, or 0.28% of all new Meta ads in the window against 6.6%.

A good part of the 70,254 are not separate campaigns at all. At least 13,207 of them, 19%, name both events in the same copy: "Black Friday/Cyber Monday", "from Black Friday to Cyber Monday", "valid until Cyber Monday". The largest Cyber Monday ad of the season by EU reach is one of these. Meta's own French ad for the Quest 3S, "Black Friday/Cyber Monday: up to €70 off" (translated), reached 10.86 million people in the EU. It ran from 13 to 28 November and was last seen on Black Friday: the most-seen Cyber Monday ad of 2025 did not run on Cyber Monday.

Half of them arrive in the last 48 hours

49% of all Cyber Monday ads launched on the Sunday or the Monday itself: 14,253 on Sunday 30 November and 20,162 on Monday 1 December. Fewer than a quarter (24%) were live before Black Friday. Another 16% launched after Cyber Monday was over, which is what "Cyber Week" and "extended" offers look like in the data.

Seen day by day against Black Friday, the pattern is sharper. Until Black Friday, Cyber Monday is a rounding error: two new Cyber Monday ads for every hundred new Black Friday ads.

The ratio peaks at 83 on Cyber Monday and never crosses 100. In the four days before Black Friday, advertisers launched 441,204 new Black Friday ads and 8,592 Cyber Monday ones. For most advertisers, the data suggests, Cyber Monday is not a campaign planned in advance. It is a headline swapped on the last weekend.

An ad switched on Monday gets Monday

Launch day shows up in reach. Among Cyber Monday ads that were shown in the EU (Meta publishes reach there, nowhere else), those launched by 27 November reached 23,178 people on average. Those launched on 30 November or 1 December reached 10,034: 43% as many.

That gap is partly mechanical, and that is the point. An ad that starts on Sunday has two days to deliver before the offer ends; one that started in the week before Black Friday had ten. The late wave still reached more people in total (146 million against 89 million) because there were more than twice as many ads in it, but each ad got less. If your Cyber Monday plan is a new creative on Monday morning, you are buying a one-day audience at the moment 20,000 other new ads are asking for the same people.

A one-day ad can still be big if it is funded like one. The most-seen ad of the season that mentions Cyber Monday without Black Friday came from KING, an Italian multi-brand retailer:

"Cyber Monday at KING! Up to 30% off your favourite brands. You only have until tonight" (translated). It ran from 1 to 2 December, reached 3.02 million people in the EU, and Brandsearch estimates its spend at about €24,300. Reach followed budget, not timing: KING bought a day of attention outright. Most of the 20,162 ads launched that Monday did not, and averaged around 10,000 people each.

Outside English, Cyber Monday barely exists

82% of Cyber Monday ads are in English, against 67% of Black Friday ads and 60% of all new Meta ads in the same window. Count Cyber Monday ads per thousand Black Friday ads in each language and the split is clear:

In Italian, there are 17 Cyber Monday ads for every thousand Black Friday ads. In German and Dutch, where "Black Week" is a common label, the Monday tends to appear as the deadline rather than the event. A German-language store selling prescription diving masks ran "Black Week, only 7 days, 20% off every mask" with the line "ends Cyber Monday, 01.12., 23:59" (translated). Cyber Monday is in that copy, but only as the end date.

If you sell mainly in continental Europe, a separate Cyber Monday campaign puts you in a very small group. If you sell in English, to the US, UK, Ireland or Australia, it is more common, though even there it is one ad for every 19 Black Friday ads.

2026 is starting a little earlier, from a very small base

Between 1 September and 28 October 2026, 1,860 new Meta ads mentioned Cyber Monday, against 891 over the same dates in 2025. The index itself grew 51% over that period, so compare shares, not raw counts: 102 Cyber Monday ads per million new Meta ads this year against 74 last year, a rise of about 39%.

What to do with Monday 30 November 2026

Put Cyber Monday in your Black Friday creative from day one, with the end time. HBADA, an office-chair brand selling in Europe through hbada.eu, launched its sale ad on 27 November 2025 with "HBADA BFCM" in the headline and "this Black Friday Cyber Monday" in the copy. It ran until 5 December and reached 821,818 people in the EU. One ad, one message, a reason to buy through the whole weekend, and nothing to rebuild on Sunday night.

Run a Cyber Monday-only ad only if you have a Cyber Monday-only offer, and the budget for one day. KING's 3 million people came from a distinct offer, "only until tonight", with a one-day budget behind it. A Black Friday discount relabelled on Monday morning competes with 20,000 other new ads for a day's delivery.

Use the Monday as a deadline, not a launch. The Body Shop's last-day ad was eight words, "Final hours. Final deals. Don't miss Cyber Monday.", pointing to the same Black Friday collection, and it reached 843,189 people in the EU. The offer was already known. The ad only announced that it was ending.

In continental Europe, say Black Week and give Monday as the end date. That matches what shoppers in German, French, Italian and Dutch feeds see from most other brands.

Check what your own competitors did last year before you decide. The averages above may hide categories where Cyber Monday is a bigger event. Searching "cyber monday" with a start date of 1 December 2025 and your competitors' domains in Brandsearch shows whether they ran a separate Monday campaign or just changed the headline, and how many people each version reached.

Where these numbers come from

All counts come from Brandsearch's index of Meta ads, pulled on 30 October 2026. An ad counts as a Cyber Monday ad when its copy, headline, cards or page name contain "cyber monday"; Black Friday likewise. Dates are launch dates. Counts are ads, not brands, and include every kind of advertiser, not only ecommerce stores. The 2025 window runs from 1 September to 15 December. Reach is the number of people in the EU that Meta publishes for each ad under EU transparency rules; averages cover only ads with published EU reach, so they say nothing about US delivery. Spend figures are Brandsearch's estimate, built from that reach and a fixed rate per country, not an amount the advertiser disclosed. For what an EU reach figure of 10,000 or 3 million actually means, see Meta Ad Library reach explained, and for last season's biggest Black Friday ads with their reach attached, Black Friday ad examples.
