How to increase ROAS

To increase ROAS you do one of two things: earn more revenue per dollar spent, or cut spend that isn't earning. Everything that works — better targeting, stronger creative, a higher-converting landing page, a bigger average order, lower cost per click, fewer wasted placements — is just a version of one of those two moves.

Before you optimise, though, know your break-even ROAS (1 ÷ profit margin) so you're aiming at the right target rather than blindly pushing the number up. If you're not sure what "good" looks like for your margins, start with what is a good ROAS? — then come back here for the levers to get there.

ROAS has only two sides — work both

Return on ad spend is a simple ratio, and that tells you exactly where the levers are:

ROAS = revenue from ads ÷ ad spend

Raise the top (more or bigger conversions from the same spend) or lower the bottom (less wasted spend for the same revenue) and ROAS rises. The mistake most people make is pulling only one lever — usually cutting spend — when the biggest, most durable gains come from the revenue side. Work both.

Lift revenue per dollar (the durable gains)

1. Raise conversion rate. More sales from the same clicks lifts ROAS one-for-one. A faster, clearer, more trustworthy landing page — matched tightly to the ad's promise — is usually the highest-leverage change you can make. Even a 2% → 2.5% conversion rate is a 25% ROAS gain.
2. Increase average order value. Bundles, volume discounts, free-shipping thresholds and post-purchase upsells raise revenue per conversion without raising ad spend at all — pure ROAS uplift.
3. Lean into retargeting and warm audiences. Warm audiences who already know you convert far better than cold ones, so their ROAS is higher. Make sure you're capturing that demand — but don't let it cannibalise the prospecting that creates it.
4. Sharpen your offer and creative. A stronger hook lifts click-through rate, which on Google feeds Quality Score and lowers CPC — a compounding win that shows up on both sides of the ratio.

Cut wasted spend (the fast gains)

5. Prune what doesn't convert. Pause the keywords, audiences, placements and ad sets that spend without returning. This is the single fastest way to raise average ROAS — you're removing the drag, not adding lift.
6. Lower CPC through relevance, not weaker inventory. A higher Quality Score cuts your cost per click for the same position, so the same conversions cost less. Cheaper clicks from lower-intent sources, on the other hand, usually convert worse and cancel the saving.
7. Add negative keywords and tighten match types. A negative keyword tells the platform which searches to skip, and match types control how loosely your keywords trigger ads. Every click from an irrelevant search is spend with near-zero return. Cutting them concentrates budget on traffic that can actually convert.
8. Reallocate to your winners. Once you know which campaigns clear your break-even comfortably, shift budget toward them — and away from the ones that only ever hover around it.

A worked example

Say a store spends $10,000 and drives $30,000 in revenue — a 3× ROAS. Its break-even is 2.5× (a 40% margin), so it's profitable but not by much. Two changes, neither dramatic:

• Landing-page work lifts conversion rate by 25%, so the same $10,000 now earns $37,500.
• Pruning wasted keywords cuts spend to $8,500 for the same conversions.

New ROAS:

4.4× = $37,500 ÷ $8,500

A 3× became a 4.4× — a 47% improvement — without a bigger budget or a new channel, just by working both sides of the ratio. Model your own version with the calculator below.

Three mistakes that quietly cap ROAS

• Cutting spend to hit a ROAS target. You can always raise ROAS by shrinking to your warmest audience — but you strangle growth. ROAS is a ratio, not profit; a smaller, higher-ROAS account can make less money.
• Ignoring break-even. Optimising toward a number you picked from a blog post, instead of your own break-even ROAS, means you're either leaving profit on the table or losing money while the metric looks fine.
• Trusting per-channel ROAS. Every platform claims credit for the same sales. Watch your blended ROAS (MER — total revenue ÷ total ad spend across every channel) so you don't scale a channel that only looks profitable in its own dashboard.

Frequently asked questions

What's the fastest way to increase ROAS?

Usually the quickest win is cutting the worst-performing spend — pausing keywords, audiences or placements that spend without converting immediately raises your average return. Lifting conversion rate and average order value take longer but raise the ceiling; trimming waste moves the number this week.

Does lowering CPC increase ROAS?

Yes, directly — if the same clicks convert at the same rate but cost less, revenue per dollar of spend rises. The catch is that chasing cheaper clicks can bring lower-intent traffic that converts worse, cancelling the gain. Lower CPC through better relevance and Quality Score (Google's rating of how relevant your ad is), not by chasing cheap, low-quality ad slots.

How do I increase ROAS on Facebook or Google?

The levers are the same on both: tighter targeting, stronger creative and offers, a faster higher-converting landing page, and cutting waste. On Google, Quality Score lowers CPC; on Meta, creative and audience relevance do the heavy lifting. Judge each channel on its blended return, not just its in-platform ROAS.

Is a higher ROAS always the goal?

Not always. Pushing ROAS as high as possible usually means shrinking to only your warmest audiences, which caps growth. Many businesses deliberately run a lower ROAS on prospecting to acquire customers, as long as it stays above break-even. See our guide on what a good ROAS is for how to set the right target.

Key takeaways

• ROAS = revenue ÷ ad spend — raise the top or lower the bottom, and work both sides.
• Durable gains come from the revenue side: conversion rate, average order value, retargeting, offer.
• Fast gains come from cutting waste: prune non-converters, lower CPC via relevance, add negatives.
• Aim at your break-even ROAS, not a number from a blog — see what is a good ROAS?
• Model the levers with the ROAS calculator and Campaign Forecast.
