When Should You Raise Ad Budgets for Black Friday? Meta and Google Timing by Week
A successful Black Friday ad spend strategy starts in early November, with gradual budget increases for proven Meta and Google campaigns. Scale spending two to three weeks before Black Friday when CPA, ROAS, and profit margins support it, then adjust budgets based on live BFCM performance.
Key Highlights
- Start testing creative, checking tracking, and building retargeting audiences before the main BFCM rush.
- Raise budgets in stages when CPA, ROAS, and conversion performance support the increase.
- Give Meta and Google different budget priorities based on how each campaign contributes to sales.
- Use Black Friday performance data to guide weekend spending, rather than dividing the budget evenly by default.
Why Should You Increase Black Friday Ad Budgets Before Peak Shopping Days?
Increasing ad budgets before Black Friday gives you time to scale proven campaigns, build retargeting audiences, and capture early holiday demand. Before increasing spend, complete your Black Friday 2026 preparation checklist to verify tracking, inventory, promotional offers, and store readiness. Scale gradually when CPA, ROAS, and profit margins support the increase.
When to Increase Meta Ads Budget for Black Friday 2026?
Increase Meta budgets around two to three weeks before Black Friday if your campaigns are already meeting their CPA or ROAS targets. Scale the ads that convert profitably, and avoid raising budgets across the entire account just because the sale is approaching.
Use CPA, ROAS, conversion rate, and contribution margin to decide how much more a campaign can spend. CPM helps you track the cost of reaching shoppers, but it cannot tell you whether the campaign is generating profitable sales.
Make budget changes in response to what you see:
- CPA is within target and conversion rate is stable: Increase spend gradually and check whether performance holds.
- CPA is rising, but ROAS remains profitable: Review margins and conversion trends before deciding whether to continue scaling.
- CPA exceeds your profitable limit: Hold further increases and investigate the cause rather than spending more to force volume.
Pay attention to placements, too. Triple Whale’s BFCM 2025 analysis reported Reels CPMs 30–40% lower than Feed CPMs. That makes Reels worth testing when Feed costs rise, but lower CPMs alone are not a reason to scale the budget. Compare conversion quality and profitability across placements before reallocating spend.
By mid-November, avoid unnecessary campaign restructuring. Keep proven creative and audiences in place, and adjust the budget based on results. If you need help evaluating campaign structure or placement performance, EvenDigit can review your paid social strategy and guide you on what works.
Why does Meta ads CPM increase during BFCM?
Meta ads CPM (cost per 1,000 ad impressions) increases during Black Friday and Cyber Monday (BFCM) because more advertisers compete for the same high-intent shoppers, while the available advertising inventory cannot expand at the same rate as demand. Retailers, D2C brands, marketplaces, and even non-retail advertisers compete more aggressively for consumer attention during the holiday shopping season.
For Shopify brands running Meta or other paid social campaigns, the result is often higher costs to reach the same audience, even before accounting for changes in conversion rates.
How much can CPM increase during BFCM?
Recent Meta advertising benchmarks show just how sharply costs can rise, although the increase varies by audience, industry, and campaign setup.
| Period | CPM change in 2025 |
| Week of Nov. 17–23 | +9% vs. October baseline |
| BFCM week, Nov. 24–30 | +35% |
| Black Friday, Nov. 28 | +57% |
| Cyber Monday, Dec. 1 | +41% |
Does a higher CPM mean your Meta ads will perform worse?
No. Higher CPM increases the cost of reaching people, but it doesn’t automatically increase your cost per purchase. If shoppers are more likely to buy during BFCM, stronger conversion rates can offset the higher impression costs.
For example, consider two hypothetical scenarios:
| Metric | Normal period | BFCM |
| CPM | $15 | $24 |
| Impressions | 10,000 | 10,000 |
| Ad spend | $150 | $240 |
| Click-through rate | 1.5% | 2% |
| Website conversion rate | 2% | 3% |
| Purchases | 3 | 6 |
| Cost per purchase | $50 | $40 |
In this example, CPM rises by 60%, yet cost per purchase falls by 20% because the ad attracts more clicks and a higher share of visitors convert.
These figures are illustrative, not industry benchmarks.
When to Increase Google Ads Budget for Black Friday 2026?
Raise your Google budgets prior to Black Friday exclusively on profitable Search, Shopping, and Performance Max campaigns that are actively losing impression share due to strict budget constraints.
Search can capture shoppers actively looking for products, while Shopping and Performance Max can help surface products across Google’s advertising inventory. Triple Whale’s BFCM 2025 analysis reported a 4.68x ROAS for Search and 3.15x for Performance Max across its dataset.
Always check your campaign metrics first. A campaign being “limited by budget” does not automatically mean it deserves more capital. Review your Search lost impression share (budget) indicators.
If a campaign is missing out on eligible buyers but its CPA or ROAS is healthy, lift the budget to capture those sales. If returns are already below your profit threshold, fix the performance issues before adding a single dollar.
Should I keep the same ad budget for Black Friday and Cyber Monday?
Plan for Black Friday and Cyber Monday separately rather than automatically splitting spend evenly. Optmyzr’s analysis of 5,134 ecommerce accounts found that Black Friday 2025 generated $144.8 million in Google Ads conversion value, compared with $107.9 million on Cyber Monday.
Black Friday also recorded a higher ROAS in that dataset. Keep enough budget available for the stronger opportunities you see on each day, with particular attention to Black Friday demand.
Before increasing Google Ads spend, check that:
- Campaigns are losing eligible traffic because of budget limits, not simply underperforming.
- Merchant Center prices, product availability, and promotions match your landing pages.
- Google Ads and GA4 are not counting the same purchase twice.
- Your bidding targets still reflect current margins and discount levels.

FAQs
How much do Meta CPMs rise during Black Friday week?
Lebesgue found that median Meta CPMs rose 59% above September levels during Black Friday week 2025 and 84% on Black Friday itself. Treat these figures as benchmarks, not forecasts for your account, because auction costs and results vary by advertiser.
Is Black Friday or Cyber Monday more valuable for Google Ads?
Black Friday generated more Google Ads conversion value than Cyber Monday in Optmyzr’s 2025 analysis of 5,134 ecommerce accounts. Plan for strong Black Friday demand, then adjust the remaining budget based on your own campaign performance through Cyber Monday.
Should I turn off Google’s seasonality bid adjustments for Black Friday?
Don’t apply seasonality adjustments automatically. Optmyzr’s multi-year analysis found weaker ROAS changes among advertisers using them than among its comparison group. Review your account’s conversion patterns and bidding setup before deciding whether an adjustment is justified.
How much should I raise my daily ad budget during BFCM week?
There is no universal increase that works for every account. Raise budgets in measured steps, then check CPA, ROAS, conversion volume, and margin before increasing spend again. The size of each increase should reflect how reliably the campaign can absorb more budget.
What if my Google Ads campaigns are losing impression share to budget?
Increase the budget if a campaign is missing eligible traffic because of its budget limit and is still meeting your profitability target. If CPA or ROAS is already below target, investigate performance first rather than paying for more traffic that may not convert profitably.
