September brings plenty of opportunities to engage sports audiences: European club competitions and the UEFA Nations League get underway, the US Open reaches its final stages, the Formula 1 season continues, and major local tournaments take place across selected GEOs. N1 Partners has put together the key events of the month, the latest promotions, and the team’s recommendations on the events and markets affiliates should keep an eye on.

Sports traffic: what changes in September

August saw the return of European club football, along with the qualifying rounds of European competitions. September marks the next stage of the season, with regular tournament fixtures and a packed schedule across the top leagues.

The main shift is that isolated traffic spikes give way to a steady stream of top-level games. This makes it easier to plan campaigns several weeks ahead, allocate traffic across events in advance, and shift the audience’s attention as the sports calendar evolves.

Key sport events

UEFA Champions and Europa League

The first league-phase matchdays of the UEFA Champions League and UEFA Europa League open the regular part of the European club season. Campaigns can focus on individual matches and teams while taking into account the sports interests of audiences in each GEO.

Formula 1: Madrid and Azerbaijan Grand Prix

Formula 1 offers two separate opportunities in September: the Madrid Grand Prix and the Azerbaijan Grand Prix. Campaigns can take into account audience interest in motorsport and test GEOs with different levels of engagement with Formula 1.

N1 Partners insights

N1 Partners experts shared their recommendations on how to approach sports campaigns in the current event calendar.

1. After the major summer tournaments, which events should sports traffic be shifted to?
There is no need to move the entire traffic volume to a single new event or news hook overnight. It is more effective to gradually reallocate the budget as audience interest shifts.

It also makes sense to keep part of the budget flexible and allocate it based on the performance of ongoing campaigns. This allows high-performing setups to be scaled without having to rebuild campaigns from scratch.

2. Which GEOs look the most promising in September?
The most packed calendars are in Germany, Australia, and Canada. These markets offer multiple relevant sports events throughout the month, making it possible to engage the same audience across different occasions.

It is also worth highlighting Norway and Denmark: Nations League fixtures involving the national teams provide a clear local hook and a strong connection to the GEO.

3. How can affiliates make the most of a sequence of events within the same GEO?
Instead of running separate campaigns around each individual event, affiliates can map out a sequence of transitions in advance. For each market, it is possible to define several directions and the conditions for shifting the focus from one to another. This makes it easier to keep working with an audience that has already been acquired.

Tips for working with sports traffic in September

This month offers several ways to structure campaigns, from preparing for major events to running live activations and re-engaging audiences after an event has ended.

1. Tailor your messaging to each stage of the tournament.
For the US Open, AFL Finals, and VALORANT World Championship, interest remains high for several weeks, but the most relevant communication angle changes over time. At the start, campaigns can focus on the tournament itself; as the final approaches, the focus can shift to specific participants and decisive matches.

2. Prepare dedicated materials around draws and confirmed matchups.
For the Champions League and Europa League, once the fixture schedule is confirmed, there is an opportunity to move away from generic messaging and focus on specific clubs, matches, and national rivalries. This is particularly relevant for Germany, Portugal, and other European GEOs.

3. Use shorter events as additional touchpoints between major tournaments.
Alongside longer-running competitions, there are several high-impact dates throughout the month – UFC Paris, the Italian Grand Prix, the Spanish Grand Prix, the NFL in Melbourne, and Nations League fixtures. These can be used as standalone short-term campaigns without tying the entire strategy to a single tournament.

4. Look at the “discipline + GEO” combination rather than overall sports traffic volume alone.
September provides an opportunity to compare different models: Formula 1 – Italy and Spain, AFL and NFL – Australia, UFC – France, cycling – Canada, football – most European GEOs. This breakdown can help identify which sports verticals resonate best with specific audiences and which combinations are worth developing further.
