What Is a Good ROAS? UK Industry Benchmarks for 2026

ROAS in one sentence

ROAS — Return On Ad Spend — is revenue divided by ad spend. A 5× ROAS means £5 of attributable revenue for every £1 of paid media. It's a top-line metric: it doesn't account for fulfilment, gross margin, management fees, or platform costs. That's where most ROAS conversations go wrong.

ROI is different. ROI measures profit per pound of total cost (ad spend + fees + cost of goods + overheads). MER — Marketing Efficiency Ratio — is total revenue divided by total marketing spend across all channels, used as a portfolio-level health check. Three different metrics, three different decisions.

For the full ROAS definition with formulas, examples, and platform-specific reporting nuances, see the companion piece on Google Ads CPC benchmarks.

Use the ROAS calculator

Enter your monthly ad spend, attributable revenue, gross margin, and industry. The calculator returns your ROAS, your POAS (Profit on Ad Spend), your break-even ROAS, and where you sit against the industry benchmark range. POAS is the number that actually predicts whether the campaign makes you money.

What "good" actually means — break-even ROAS

The most important number in any ROAS conversation is your break-even ROAS — the ROAS at which gross profit from incremental revenue exactly matches the ad spend that produced it. The formula is simple: 1 ÷ gross margin.

A 30% margin business needs a ROAS of 3.33× just to break even on ad spend. A 70% margin business breaks even at 1.43×. This single number explains why the same headline ROAS produces wildly different outcomes across verticals.

Most healthy accounts target 2× break-even — the "comfortable ROAS" column above. That gives enough headroom to absorb attribution noise, seasonal swings, and CPC inflation without dropping into loss-making territory.

Real client ROAS proof

Why ROAS varies so much by channel and bid strategy

Channel ROAS norms differ materially. Brand-defence Search Ads against your own brand terms commonly return 8–20× because the buyer is already converting; non-brand search returns 3–6× because you're acquiring net-new demand. Shopping and Performance Max sit in between. Display and YouTube are upper-funnel and rarely produce direct-response ROAS comparable to Search.

Bid strategy compounds the variance. Manual CPC bidding gives full control but rarely beats the algorithm above 1,000 weekly clicks. Target ROAS constrains spend to a return target. Maximise Conversion Value scales aggressively but can over-spend on low-margin SKUs unless margin-tier custom labels are configured.

Target ROAS vs actual ROAS — what bid strategy you set vs what you get

Setting a Target ROAS of 5× doesn't guarantee a 5× return. Account variables affect actual delivered ROAS heavily — feed quality, conversion-tracking accuracy, audience signals, asset group structure, landing-page conversion rate. Over-restrictive Target ROAS chokes volume and the algorithm under-spends. Under-restrictive Target ROAS bleeds budget chasing impressions.

The practical rule: set Target ROAS at 80–90% of your trailing 30-day actual ROAS, then nudge upward as performance proves out. Setting it at 130% of current actual is the most common cause of suddenly stalled spend.

How to lift your ROAS

Eight practical levers, in rough order of impact for most accounts:

1. Margin-tier custom labels for Shopping

Populate custom_label_0 with margin tier (Tier 1 = highest margin, Tier 3 = lowest). Run Tier 1 with aggressive Target ROAS, Tier 3 with Maximum CPC caps. This single change typically lifts blended ROAS 20–40% without changing spend.

2. Conversion-tracking accuracy + value-based tracking

Smart Bidding optimises against the data you give it. Pass actual order value (not flat conversion = 1), include refund signals, and use enhanced conversions for cookieless attribution.

3. Feed quality (titles, attributes, custom labels)

Title structure alone — moving from "SKU-7741-K" to "Bunk Bed Triple Sleeper Solid Pine Single + Single Over Double White" — typically lifts CTR 30–80% and ROAS proportionally. Full deep-dive in our 47-point feed optimisation checklist.

4. Audience signals on PMax asset groups

Performance Max blends signals across Search, Shopping, Display and YouTube. Without audience signals, asset groups optimise blind. With customer-match lists, in-market segments, and detailed demographics, asset-group ROAS typically climbs 15–30%.

5. Negative keyword discipline

Weekly negative-keyword reviews on Search campaigns, monthly on Shopping and PMax (via search-terms reports + brand-exclusion lists for non-brand campaigns).

6. CSS partner activation

Routing Shopping spend through a CSS partner reduces effective CPC by ~20%. Lower CPC at constant revenue = higher ROAS. Read the CSS partner explainer.

7. Brand vs non-brand campaign separation

Brand campaigns typically return 8–20× ROAS but represent capture of existing demand, not net-new acquisition. Reporting them blended with non-brand inflates headline ROAS and disguises true acquisition cost.

8. Customer-LTV-based bid logic

For high-LTV verticals (B2B SaaS, subscription, repeat e-com), bidding to first-purchase value under-weights long-term contribution. Pass predicted LTV as conversion value where attribution allows.

When low ROAS is actually fine

Counter-intuitively, sometimes a low ROAS is the right strategy. Five common scenarios:

• New customer acquisition where LTV > first purchase. A subscription business acquiring a customer at break-even on first purchase is actually highly profitable over the contract.
• Brand-building campaigns. YouTube TOFU and Demand Gen rarely return direct-response ROAS but lift branded search and direct traffic for months afterwards.
• Product launches. Acquiring early reviewers and demand-validation traffic at low ROAS is normal investment, not waste.
• Market expansion. Entering a new geo or vertical typically runs at half normal ROAS for the first 60–90 days as the algorithm learns.
• Competitive defence. Bidding on competitor brand terms returns lower ROAS but denies them airtime.

The mistake is optimising for ROAS at the cost of strategic objectives. The fix is to set ROAS targets per campaign type, not blanket account-level.

Methodology

Industry benchmarks above combine WordStream UK 2026 cross-vertical data with the Visionary client portfolio Q1 2026 — 47 UK and EU accounts spanning e-commerce, B2B SaaS, B2B services, lead gen, local services, travel, and education. Median figures are weighted by spend; range bounds reflect 10th and 90th percentile observed performance.

Client case-study figures are reported as published in their respective case study pages and are validated against direct platform exports (Google Ads, Microsoft Ads, GA4) before publication.
