Fashion Seasonality & Markdown Timing for Google Ads
Managing PPC through fashion sales cycles, end-of-season clearance, and markdown optimisation without destroying your profit margins.
Fashion retail operates on a fundamentally different rhythm than most ecommerce. Your inventory has a shelf life measured in weeks, not years. A jumper that commands full margin in October becomes a clearance liability by January. Yet most PPC strategies treat fashion like any other category, bidding the same way in week one of a season as they do in week twelve.
This disconnect between seasonal commercial reality and static bidding strategy is where fashion retailers haemorrhage margin. The challenge is not just knowing when to markdown, but understanding how your advertising strategy must evolve through each phase of the seasonal cycle.
The Seasonal Reality
Fashion operates in overlapping seasonal windows that most PPC platforms completely ignore:
The Four Phases of Fashion Inventory
Each phase demands a fundamentally different bidding approach. Yet smart bidding treats them all the same, optimising for revenue regardless of whether you are selling a full-margin new arrival or a 70% off clearance item.
Markdown Timing Strategy
The timing of your markdowns should dictate the timing of your bid adjustments, not the other way around. Most retailers markdown and then wonder why their ROAS looks great while their bank account tells a different story.
The Markdown Profit Trap
A product marked down 40% often has its margin reduced by 80% or more. If your advertising costs remain constant, that sale might be generating zero profit or an actual loss, despite looking like a successful conversion in Google Ads.
Pre-Markdown Strategy
Before marking down, intensify spend on full-margin inventory. Use custom labels to separate new arrivals from soon-to-be-marked-down stock. Push budget toward items that still carry healthy margins rather than spreading spend evenly.
During Markdown Windows
Reduce bids in proportion to margin reduction, not discount percentage. A 30% discount might require a 50% bid reduction to maintain profitability. Use margin-aware bidding through custom label segmentation rather than letting smart bidding chase volume.
Bidding Through Sales Cycles
Your bidding strategy should evolve weekly, not quarterly. Fashion moves too quickly for set-and-forget approaches.
Weekly Rhythm Adjustments
- Week 1-4:New season launch. Maximum bids on new arrivals. Suppress previous season.
- Week 5-8:Peak selling. Maintain bids on best sellers. Begin reducing on slow movers.
- Week 9-12:Transition. Cut bids on broken sizes. Focus on complete size runs only.
- Week 13+:Clearance. Minimal bids. Let organic and brand cover clearance traffic.
End-of-Season Clearance
End-of-season clearance is not a time to scale PPC spend. It is a time to question whether PPC spend should exist at all on clearance inventory.
The Clearance Calculation
Before advertising any clearance item, calculate the true margin after discount:
- • Original margin minus discount equals remaining margin
- • Subtract estimated returns rate (often higher on sale items)
- • Subtract payment processing and fulfilment costs
- • What remains is your maximum allowable advertising cost
For most clearance items, this number is close to zero or negative.
The strategic choice is often to exclude clearance inventory from paid advertising entirely and rely on email, organic traffic, and brand searches to clear remaining stock. Advertising clearance at the same intensity as full-margin stock is how fashion retailers turn profitable years into break-even ones.
PMax Seasonal Adjustments
Performance Max presents unique challenges for seasonal fashion businesses because it conflates all inventory into unified bidding. The algorithm cannot distinguish between a new arrival at full margin and a clearance item at 70% off.
Structural Solutions
- •Separate PMax campaigns by season or collection, not just product type
- •Use listing group exclusions to remove clearance from main campaigns
- •Create dedicated clearance campaigns with dramatically lower ROAS targets
- •Update custom labels weekly to reflect current markdown status
Conclusion
Fashion seasonality demands a dynamic approach to PPC that most agencies and in-house teams fail to implement. The rhythm of your advertising must match the rhythm of your inventory lifecycle, from full-margin launch through to clearance liquidation.
The retailers who master this alignment do not just outperform on ROAS. They protect margin through every phase of the seasonal cycle, ensuring that strong sales translate into strong profits rather than impressive revenue figures masking commercial erosion.
