New How Seasonality Affects Traffic Arbitrage: GEOs, Verticals, Budgets, and Scaling

Advertising campaign performance can change even without major adjustments to the campaign setup. During certain periods, demand rises, ad auctions become more expensive, budgets are spent faster, and creatives may lose relevance sooner.

Seasonality is one reason for these changes.

Before the holidays, users search more actively for gifts. As warmer weather approaches, interest in certain product categories may increase. When people plan their vacations, demand for tickets, accommodation, and travel services can rise. Along with demand, competition in ad auctions, traffic costs, and audience behavior also change.

To avoid being caught off guard by a seasonal surge, teams need to understand in advance which GEOs and verticals it may affect, how much budget they will need, whether their payment infrastructure can handle higher ad spend, and when to move from testing to scaling.

What Counts as Seasonality?

Seasonality is a predictable change in demand, audience behavior, or advertising competition during a particular period. It may be driven by the time of year, a holiday, a local event, or a brief surge in interest.

Media buyers most often encounter several types of seasonality:

• Calendar-based. New Year, Valentine's Day, Black Friday, and the start of the school year.
• Weather-related. Hot weather, cold weather, allergy season, and the start of the beach season.
• Local. National holidays, religious events, school breaks, and other periods specific to a particular country.
• Event-driven. A major sports tournament, festival, premiere, or another event that temporarily changes audience interest.

Seasonality does not mean that any offer will automatically become profitable. It simply creates a period when audience needs may be stronger or change faster than usual.

Results still depend on the offer, creative, landing page, traffic costs, competition, and how well the campaign is configured.

How Seasonality Relates to Affiliate Marketing Verticals

Each vertical responds to the calendar differently. Some are influenced by holidays, while others depend more on weather, major sporting events, or periods of increased spending.

• E-commerce. Interest may increase before Black Friday, the winter holidays, Valentine's Day, and the start of the school year. Creatives can highlight a seasonal offer, delivery times, or a gift-giving occasion.
• Nutra. Demand for some offers may change with the season. For example, interest in products related to fitness and appearance may grow ahead of warmer weather, while other categories are more affected by weather conditions or local factors. The creative and the motivation behind the purchase should match the actual context of the target GEO.
• Dating. Interest may change before Valentine's Day, during holiday periods, and throughout the vacation season. Creatives should be adapted to the event, the audience's age, and the characteristics of the specific GEO.
• Finance. Demand may change during periods of major purchases, holiday spending, travel, or other seasonal financial needs. Ads should present a clear use case for the product and communicate the offer's terms accurately.
• Sports-related offers. Interest may increase during major matches, championships, and finals. These campaigns often have a short window of peak relevance, so they need to be prepared for a specific event.
• Lead generation. Demand depends on the niche: education offers may generate more leads before a new academic period, home services may attract more interest during renovation periods or seasonal transitions, and insurance products may see greater demand before travel or policy renewals.

These examples should not be treated as a ready-made campaign calendar. For instance, demand for an education lead generation offer will depend on the learning format, the audience's age, and the admissions schedule in the target GEO.

Users may start searching for courses or educational programs several months before they begin. Waiting until the actual start date may therefore be too late.

Why Each GEO Needs Its Own Seasonal Calendar

In traffic arbitrage, a GEO is the country or region whose audience you target with advertising. Seasonal patterns differ across GEOs because of climate, holidays, culture, purchasing power, and user habits.

A simple example: a summer creative featuring a beach may be relevant in one region but fail to match the weather and audience mood in another. Similarly, a local holiday may significantly affect purchases in one country while having little impact in a neighboring market.

Before launching, check:

1. Which holidays and public days off fall within the selected period.
2. When the relevant season begins in the country.
3. Whether demand for the product changes during that period.
4. Whether the seasonal offer, language, currency, and promotion end date are correctly localized.
5. Whether local advertising restrictions apply to the selected vertical.

For planning, you can use Google Trends, ad libraries, affiliate network data, your team's historical performance data, and platform marketing calendars.

For example, major advertising platforms often publish separate marketing calendars for different regions. There is no universal campaign calendar that works for every GEO.

What Happens to Advertising Budgets During Peak Season?

During periods of high demand, more advertisers may enter the ad auction. As a result, CPM, CPC, or CPA can increase.

However, more expensive traffic does not automatically mean that a campaign is performing worse. If conversion rates also rise and the campaign remains financially viable overall, a higher CPM or CPC may be acceptable.

That is why you need to evaluate the campaign's overall economics rather than a single metric:

• how much an impression or click costs;
• how many users reach the landing page;
• what percentage of visitors complete the target action;
• the actual CPA;
• the approval rate and revenue per approved conversion;
• how much remains after advertising and payment costs.

A testing budget should not be defined solely as a fixed amount, either. It is better to base it on your target CPA and the number of conversions needed for an initial assessment.

When data is limited, one chance sale or one unsuccessful lead can create a misleading impression of the entire campaign setup.

During peak season, it is important to consider not only the total advertising budget but also how quickly it is being spent. If a team scales several campaigns or ad accounts at the same time, the demands on cards, balances, and payment limits also increase.

How to Scale a Seasonal Campaign

It is easy to mistake a seasonal increase in demand for consistently strong campaign performance. A few successful conversions do not mean that the budget should immediately be multiplied several times over.

Before scaling, check that:

• the campaign has collected enough data rather than produced an isolated result;
• CPA remains within acceptable limits;
• the approval rate and lead quality have not declined;
• the offer's conversion cap allows for the planned volume;
• the affiliate program is not planning to change its terms;
• creatives are not showing signs of rapid fatigue;
• balances, cards, and payment limits can support the new spending pace.

You can scale by gradually increasing the budget or adding new creatives, audiences, or individual GEOs.

Avoid combining different countries into one group simply because they belong to the same region. Differences in traffic costs and conversion rates can hide the actual performance of each GEO.

Managing the end of the season is equally important. As interest begins to decline, budgets that were justified just yesterday can quickly become unprofitable.

After the peak, check CPA, conversion rates, and ad frequency more often, remove outdated creatives, and gradually adjust spending.

Example: Preparing an E-commerce Campaign for Black Friday

Imagine a team promoting a product across several European GEOs. Instead of launching once on the day of the sale, it divides the work into stages:

1. Checks the offer's terms, delivery options, and product availability in each country.
2. Prepares localized creatives with the correct language, currency, and offer end date.
3. Tests several advertising approaches in advance with a smaller budget.
4. Keeps the creatives and audiences that deliver an acceptable CPA.
5. Increases the budget when it sees actual growth in demand and consistent conversions.
6. Checks whether available balances and payment limits can support the new spending pace.
7. Turns off discount messaging and reviews the budget once the promotion ends.

In this scenario, seasonality does not replace testing. It helps the team choose the right launch window and prepare resources for a potential increase in volume.

Managing Payments During Seasonal Peaks

As campaigns scale, they spend their budgets faster, reach advertising platform payment thresholds more frequently, and place greater demands on cards.

If a team works with several ad accounts at once, insufficient funds on an individual card or an overlooked limit can stop a campaign precisely when demand is high.

Before scaling, check balances, available limits, and budget allocation across cards, and prepare a backup plan in case a payment is declined.

With Pay2.House, teams can issue separate virtual cards for ad accounts, top them up, and allocate budgets across campaigns. This helps them track spending separately and keep payments for different activities apart.

For campaigns with a high spending pace, teams can also use Auto Top-Up. The team sets a minimum card balance and an automatic top-up amount, after which the system tops up the card when the specified threshold is reached.

During seasonal scaling, this reduces reliance on manually checking every balance and helps prepare payment infrastructure for higher ad spend before the peak period begins.

Conclusion

Seasonality affects more than demand. It can change competition in ad auctions, customer acquisition costs, the pace of spending, and the lifespan of creatives.

That is why a seasonal campaign is best planned as a complete cycle: select a relevant GEO, assess the vertical, test the campaign setup, prepare the budget and payment infrastructure, and define the conditions for scaling or reducing spend.

Start with a calendar of key events for your GEOs and compare it with data from previous campaigns. This will help you identify periods that actually suit your offer instead of launching around every popular holiday.
