Black Friday/Cyber Monday is the most intense period of the e-commerce calendar. High stakes, high spending, high pressure, and often, high reward. But once the dust settles, brands that truly win are the ones who pause, analyze, and extract insights that will inform their strategy for the next 12 months.
A strong BFCM post-mortem isn’t just a recap, it’s a roadmap. Below are the key areas brands should be digging into to understand what worked, what didn’t, and how to build a smarter, more efficient strategy moving forward.
Revenue vs. Forecast (and YoY Performance)
Start with the big picture: Did you hit your goals? Beyond that, how did your performance compare to last year? Look at spikes, dips, and what drove them – whether it was creative, offer structure, channel spend, or product mix.
Profitability (Not Just Revenue)
BFCM can generate huge sales, but margins often take the hit. Evaluate:
- How discounting impacted overall profitability
- Which products maintained healthy margins
- Whether certain deals cannibalized higher-margin items
This is where brands often uncover their biggest opportunities for next year.
Creative Performance Insights
Your creatives tell a story. Which ones:
- Stopped the scroll?
- Drove high CTRs?
- Converted efficiently?
- Worked best for TOF vs. BOF audiences?
This is your blueprint for creative production in 2026.
Offer Effectiveness
Not all discounts are created equal. Assess:
- Which promotions drove the highest conversion
- How bundles compared to sitewide discounts
- Whether certain products acted as purchase “gateways”
Your customers just told you what motivates them. Listen closely.
Customer Acquisition vs. Retention
BFCM is a major driver of new customers but they’re only valuable if they return. Look at:
- Ratio of returning vs. new buyers
- AOV differences between segments
- How loyalty or VIP customers responded
- Whether returning customers spent more or less YoY
This is essential for long-term revenue planning.
Website & Conversion Rate Analysis
Your website was under maximum pressure. Review:
- Conversion rate changes
- Checkout drop-off points
- Load times and any slowdowns
- Landing page vs. PDP performance
Small friction points during BFCM equal large revenue losses and great optimization opportunities.
Inventory & Fulfillment Health Check
Operational performance can make or break BFCM. Evaluate:
- Fastest-selling items
- Slow-moving stock
- Stockouts and whether they helped or hurt
- Shipping delays, fulfillment issues, or customer complaints
These insights inform product forecasting and operations planning.
Email & SMS Performance
These channels often carry the highest ROI. Measure:
- Open and click-through rates by audience segment
- Subject lines that drove engagement
- Performance of automations vs. campaigns
- Sales driven by loyalty or VIP lists
Email and SMS often reveal your most reliable, highest-intent segment
Audience Insights
Which audiences were worth the spend?
- Demographic or interest group performance
- High- vs. low-quality audiences
- Rising audiences you should test more deeply
- Audiences that no longer justify investment
This sharpens targeting long after BFCM is over.
Attribution Review
BFCM exposes the gaps in every attribution model. Compare:
- Platform-reported conversions
- GA4
- Your attribution tool (if applicable)
Look for discrepancies, inflation, or channels gaining credit unfairly.
LTV Potential of New Customers
Not all new customers are equal. Early signals matter:
- Did they buy high-margin products?
- Did they explore multiple categories?
- Are they opening post-purchase emails?
This predicts how valuable your BFCM buyers will be long term.
Competitor Benchmarking
What did other brands in your space do?
- Standout offers
- Creative trends
- Messaging angles
- Platform focuses (e.g., TikTok vs. Meta vs. Google)
This helps you understand category expectations and identify differentiation opportunities.
Operational Learnings
No BFCM runs perfectly. Discuss internally:
- What bottlenecks did your team face?
- Did you have enough creative?
- Were campaign builds too rushed?
- How did cross-functional communication hold up?
Process improvements can save tens of thousands next year.
Budget Allocation Review
Where did your money go? More importantly:
- Where should it have gone?
- Which channels deserved earlier scaling?
- Which ones under-delivered despite high spend?
This informs smarter budget planning for the next 3–6 months.
Customer Feedback & Social Listening
Customers are brutally honest during BFCM. Look at:
- Common complaints
- Repetitive praise
- Sentiment shifts
- Product feedback you didn’t expect
Your customers just ran a real-time focus group for you.
Biggest Wins, Misses & Surprises
Wrap up by summarizing your biggest:
- Breakthroughs
