Smart Bidding Strategies for EOFY Sales

EOFY is one of the most competitive periods for Google Ads sales, with brands aggressively increasing spend to capture high-intent demand.

In this environment, success isn’t driven by budget alone; it’s driven by data-driven bidding decisions.

This is where Google Ads smart bidding becomes essential. By leveraging automation, machine learning, and real-time signals, brands can improve efficiency, reduce wasted spend, and maximise performance during peak seasonal demand.

So, how can brands use a smart bidding Google Ads strategy to scale effectively during EOFY?

Google Ads smart bidding is a subset of automated bidding that uses machine learning to optimise bids for conversions or conversion value in every single auction, in real time.

Unlike broader automated bidding strategies (such as Maximise Clicks), smart bidding is specifically focused on conversion outcomes. Instead of manually adjusting bids, smart bidding analyses a rich set of signals at auction time, including:

• User intent
• Device and location
• Time of day
• Historical conversion data
• Browser, operating system, and language
• This makes it easier to optimise campaigns as they grow.
• During EOFY, this becomes critical.

As competition increases and high-intent search traffic surges, manual bidding struggles to keep up with rapid changes in demand. Smart bidding allows brands to:

• Allow brands to capitalise on peak moments
• Reduce wasted spend on low-intent traffic
• Maintain efficiency even as budgets scale.

EOFY campaigns are driven by urgency, discounts, and increased consumer intent.

Smart bidding thrives in these conditions because it continuously adjusts based on real-time data.

During EOFY, Google Ads smart bidding can:

• Increase bids for high-converting users
• Reduce spend on low-intent traffic
• Prioritise users more likely to convert
• This dynamic approach works cohesively with the seasonal demand, ensuring budgets are allocated efficiently.

For example, when working with brands like AFL Store, smart bidding strategies, particularly Performance Max, play a key role in enabling campaigns to scale during major sales periods such as Opening Round, Finals, and Gather Round. Performance Max ads allow campaigns to access all Google channels while using real-time data to prioritise high-intent users and top-performing placements. This ensures budgets are allocated efficiently as demand fluctuates, allowing campaigns to scale effectively without compromising conversion performance or overall return.

With smart bidding aligning budget allocation with demand, brands can:

• Capture peak interest moments
• Avoid overspending on low-value clicks
• Improve overall campaign efficiency

Not all Google Ads bidding strategies perform equally during EOFY.
The most effective smart bidding Google Ads strategy depends on your campaign goals.

1. Maximise Conversions Google Ads

Best for driving volume during EOFY sales.

• Focuses on generating the highest number of conversions within budget
• Ideal for clearing inventory or driving rapid growth

2. Target CPA Bidding

Best for maintaining efficiency.

• Helps achieve consistent CPA optimisation
• Useful when margins are tight during discount-heavy periods

3. Target ROAS Strategy

Best for scaling revenue efficiently.

• Prioritises ROAS improvement
• Ensures high-value conversions are prioritised over volume

While Google Ads smart bidding is powerful, it requires the right setup.

Common mistakes include:

Insufficient conversion data

Smart bidding is only as good as the data it receives. Without clean, accurate conversion tracking in place, covering key actions like purchases, leads, and revenue, the algorithm has nothing reliable to optimise against. This is the most foundational mistake and the one most likely to silently undermine an entire campaign.

Changing strategies too frequently

Constant adjustments reset learning phases, limiting performance. During the learning phase, performance can be volatile and results aren’t representative of long-term potential.

Misaligned campaign goals

Using Maximise Conversions when ROAS is the actual priority, or Target ROAS when the goal is volume, will produce the wrong outcome regardless of how well the campaign is set up. Get clear on the primary goal before selecting a strategy.

To maximise Google Ads EOFY sales, campaigns must be structured correctly.

Key setup considerations include:

Ensure accurate conversion tracking

• Tracking needs to be accurate and comprehensive before anything else.
• Cover all key actions purchases, leads, revenue, and use enhanced conversions where possible. Smart bidding can’t optimise toward goals it can’t measure.

Align bidding strategy with goals

• Driving volume > Maximise Conversions
• Controlling acquisition cost > Target CPA
• Maximising revenue > Maximise Conversion Value or Target ROAS

Plan budget allocation strategies

• Build in enough lead time for learning Standard Search campaigns typically need 1-2 weeks to exit the learning phase. Performance Max can take 3-4 weeks given the multi-channel optimisation involved. Campaigns should be live and stable well before EOFY peaks, not launched into it.

Leverage historical data

• Review which keywords, audiences, and placements drove the strongest EOFY performance previously and use that to inform asset groups, audience signals, and budget allocation this cycle.

Smart bidding is only as effective as the data feeding it. The algorithm makes bidding decisions based on the signals it receives, and the quality, volume, and accuracy of those signals directly determines how well it performs.

The most important input is conversion data. Without sufficient volume Google recommends 30-50 conversions per campaign per month as a baseline. Smart bidding strategies can struggle to exit the learning phase and optimise effectively. This is why conversion tracking setup isn’t just a technical requirement, it’s a performance lever.

FAQs

What is the best smart bidding strategy for EOFY sales?

It depends on your primary goal.

For conversion volume, Maximise Conversions is the strongest starting point.
For revenue-focused campaigns where average order value varies, Maximise Conversion Value or Target ROAS will typically deliver better returns.

Target CPA suits campaigns where keeping acquisition costs predictable is the priority.

If you’re unsure, start with Maximise Conversions to build data, then transition to Target ROAS or Target CPA once you have sufficient conversion volume.

How long does smart bidding take to optimise?

For standard Search campaigns, the learning phase typically takes 1-2 weeks.

Performance Max campaigns can take 3-4 weeks given the multi-channel optimisation involved.

Does smart bidding work for small budgets?

It can, but there are real limitations. Smart bidding requires sufficient conversion data to optimise effectively, Google’s baseline recommendation is 30-50 conversions per campaign per month. Campaigns generating significantly less than this may struggle to exit the learning phase or deliver consistent results.

Can smart bidding improve ROAS during EOFY?

Yes. With accurate tracking and the right setup, smart bidding can significantly improve ROAS by prioritising high-value conversions. Brands that have built clean data foundations in the months prior to EOFY consistently see stronger ROAS outcomes than those setting up smart bidding for the first time during the peak.
