How to Scale Facebook Ads (4 Methods!)

Four Ways to Scale Facebook Ads

Dara Denney outlines four approaches to increasing Facebook ad spend while aiming to maintain profitability. Each approach involves different trade-offs in speed, risk, and testing requirements.

1. Increase the Budget by 20% Every 3 Days

Raise a campaign’s budget by 20% every 3 days. Denney describes this as the safest, most controlled approach, particularly for newer businesses or risk-averse advertisers. She says Facebook representatives have indicated that increases of this size and frequency do not restart the learning phase.

Trade-offs: This method is slow and requires regular monitoring. Avoid reacting too quickly to a day or two of weaker results, which may reflect holidays, current events, or normal fluctuations in purchasing behavior. Repeatedly changing, pausing, or cutting budgets can hurt performance.

2. Expand the Audience

Increase spend by adding audience groups rather than raising the budget within a single campaign or ad set.

• Lookalike audiences: If a 1% lookalike is performing well, duplicate the ad set and test the 1–2% segment.
• Interest audiences: Use audience insights to identify related interests to test, including interests associated with customer avatars.

Trade-offs: Audience expansion can help avoid concentrating more spend in one ad set, but it requires testing budget, and some audience tests will not work.

3. Duplicate and Increase the Budget

Duplicate a strong campaign or ad set, then give the copy a larger budget. In Denney’s tests, 2× and 5× budget increases produced the best results. The right multiplier depends on the desired pace and risk tolerance.

She generally uses Campaign Budget Optimization (CBO) for this approach.

Trade-offs: This method requires a larger initial commitment and may not work. A scaled campaign can take up to 5 days to match the performance of the smaller-budget version. Denney says that once it stabilizes, it can outperform the first two methods.

4. Increase Budgets on the Strongest Performers

Put more budget behind campaigns that are already performing well. Before scaling, check that the campaign setup can support additional spend:

• Audience size: Aim for at least 4 million people where possible.
• Top-of-funnel frequency: A frequency above 2 among people unfamiliar with the brand may indicate that the audience needs to be expanded.
• Creative volume: Test more creative as spend grows. Creative becomes more important as campaigns reach more people and work to maintain ROAS.
• Budget optimization: Denney recommends CBO for campaigns being scaled, even when a campaign has only one ad set.

Practical Guidance

• Match the method to your risk tolerance and desired pace. Gradual increases offer more control, while duplication and larger budget jumps can scale faster but carry more risk.
• Evaluate performance over time rather than making abrupt decisions based on brief fluctuations.
• Expand audiences and test creative as spend grows; don’t assume one audience or ad can support unlimited budget.
• Before increasing budgets, review audience size, frequency, creative testing, and CBO.

Metrics and Thresholds

Metric Guidance Budget increase 20% every 3 days for the “20–3” method Audience size At least 4 million suggested Top-of-funnel frequency Above 2 may signal a need to expand the audience Duplicate budget tests 2× and 5× worked best in Denney’s experience Stabilization period Up to 5 days for a duplicated, higher-budget campaign to match the smaller-budget campaign’s performance
