The True Cost of Google Ads Brand Campaigns: Industry Benchmarks

Brand campaigns are the most profitable-looking campaigns in most Google Ads accounts. Low CPCs, high conversion rates, impressive ROAS — the numbers are universally flattering.

But these numbers are misleading. They report the surface cost of brand advertising while hiding the true cost: the money spent on clicks you would have received for free, the opportunity cost of budget not spent on growth, and the escalating expense of an auction you cannot escape.

This guide quantifies those real costs with industry benchmarks and worked examples, so you can assess what your brand campaign is actually costing your business.

Typical brand campaign spend by company size

Brand campaign spending varies enormously by company size, industry, and competitive intensity. Here are representative ranges based on aggregated industry data and practitioner reports.

Small businesses (under £10,000/month total Google Ads spend)

Typical brand spend: £200-£800/month Percentage of total spend: 5-12% Common scenario: A local or niche business running a small brand campaign, often set up by an agency as standard practice. Competitor bidding is intermittent and usually from one or two rivals.

The issue: At this scale, £200-£800 per month might not sound like much. But if 70% of those clicks are non-incremental (the industry average), the genuine value delivered is only £60-£240 per month. The remaining spend is wasted.

For a small business with tight margins, even £500 per month in avoidable waste represents £6,000 per year that could fund non-brand campaigns, content creation, or other growth activities.

Mid-market businesses (£10,000-£100,000/month total spend)

Typical brand spend: £1,000-£8,000/month Percentage of total spend: 5-10% Common scenario: A regional or national brand with moderate search volume for their brand name. Multiple competitors may bid intermittently. Brand campaign has been running for years, rarely questioned.

The issue: At £4,000 per month (a typical mid-market figure), a brand campaign with 65% non-incremental traffic wastes £2,600 per month — or £31,200 per year. That budget could fund an additional non-brand campaign generating genuinely new customers.

Enterprise businesses (£100,000+/month total spend)

Typical brand spend: £10,000-£100,000+/month Percentage of total spend: 3-8% Common scenario: A well-known brand with high brand search volume, multiple competitors bidding consistently, and a large brand campaign managed by an agency.

The issue: Enterprise brand campaigns can waste staggering amounts. At £50,000 per month with 60% non-incremental traffic, the waste is £30,000 per month — £360,000 per year. Across multiple markets or regions, enterprise brands can waste seven figures annually on brand clicks that would have been organic visits.

Average brand CPCs by industry

Brand CPCs vary by industry, primarily driven by competition levels and Quality Score dynamics. Here are representative ranges for UK advertisers in 2026.

| Industry | Average brand CPC (no competition) | Average brand CPC (with competition) | Typical CPC increase from competition | |---|---|---|---| | E-commerce / Retail | £0.05-£0.15 | £0.20-£0.80 | 3-5x | | SaaS / Technology | £0.08-£0.25 | £0.40-£1.50 | 4-6x | | Financial services | £0.10-£0.30 | £0.60-£2.50 | 5-8x | | Insurance | £0.15-£0.40 | £1.00-£4.00 | 6-10x | | Legal services | £0.10-£0.35 | £0.50-£2.00 | 4-6x | | Travel / Hospitality | £0.05-£0.20 | £0.25-£1.00 | 4-5x | | Healthcare / Pharma | £0.10-£0.30 | £0.40-£1.50 | 3-5x | | Education | £0.05-£0.20 | £0.20-£0.80 | 3-4x | | B2B services | £0.08-£0.25 | £0.30-£1.20 | 3-5x | | Automotive | £0.08-£0.25 | £0.30-£1.00 | 3-4x |

The key insight from this table is the multiplier effect. When competitors enter the auction, brand CPCs do not just increase marginally — they increase by 3x to 10x. A brand campaign that costs £300 per month without competition can balloon to £2,000+ per month when competitors are active.

This is the mechanism through which competitors impose costs on brand owners, even when the brand owner wins every auction. The auction mechanics make this unavoidable.

The hidden costs

Surface-level brand campaign costs (CPC x clicks = spend) only tell part of the story. Several hidden costs significantly increase the true price of brand advertising.

Hidden cost 1: Cannibalised organic traffic

This is the largest hidden cost. When your brand ad appears above your organic listing, a substantial percentage of users click the ad who would have clicked the organic listing if no ad were present.

Industry benchmark: Research and incrementality tests consistently show that 50-80% of brand ad clicks are non-incremental. The exact figure depends on your brand awareness, organic ranking quality, and competitive landscape.

How to estimate your cost:

Monthly brand ad clicks x estimated cannibalisation rate x average brand CPC = monthly waste from cannibalisation

Example: 5,000 monthly brand clicks x 65% cannibalisation x £0.45 CPC = £1,462.50 wasted per month

Hidden cost 2: Opportunity cost

Every pound spent on a non-incremental brand click is a pound that could have been spent on a non-brand campaign generating a genuinely new customer.

How to estimate:

Take your monthly brand campaign waste (from the calculation above) and divide it by your non-brand CPA. The result is the number of additional new customers you could be acquiring each month.

Example: £1,462.50 waste / £35 non-brand CPA = 41 additional new customers per month not being acquired

Over a year, that is 492 customers your business is missing because the budget is tied up in non-incremental brand clicks.

Hidden cost 3: Performance Max cannibalisation

If you are running Performance Max campaigns, additional brand traffic is likely being consumed and misattributed there. PMax does not report brand vs non-brand performance clearly, making this cost even harder to detect.

Industry benchmark: Advertisers who enable brand exclusions on PMax typically see PMax ROAS drop by 20-40%, revealing the extent of brand cannibalisation that was inflating reported performance.

Hidden cost 4: Agency fees on inflated spend

If your agency charges a percentage of ad spend, brand campaign spend increases the management fee. An agency charging 15% on a brand campaign spending £4,000/month collects an additional £600/month — or £7,200/year — for managing a campaign that is largely wasted.

This is not a critique of agencies per se. But it is a real cost that should be accounted for when calculating the true expense of brand advertising.

Hidden cost 5: Decision distortion

Brand campaigns distort account-level metrics, making overall performance look better than it is. When leadership or stakeholders see blended metrics that include brand campaign performance, they get an inaccurate picture of acquisition efficiency.

This distortion can lead to poor strategic decisions: increasing total ad spend based on inflated blended ROAS, setting unrealistic targets for non-brand campaigns based on blended CPA figures, or underinvesting in other marketing channels because Google Ads "performance" looks strong.

The cost of these distorted decisions is impossible to quantify precisely but is potentially the most significant hidden cost of all.

How to calculate your true cost

You can calculate a reasonable estimate of your brand campaign's true cost using data available in your Google Ads and Analytics accounts. Here is the method.

Step 1: Determine your brand campaign spend

Pull your total brand campaign spend for the last 3 months and calculate a monthly average. Include any brand spend in PMax if you can identify it.

Step 2: Estimate your cannibalisation rate

If you have run an incrementality test, use your measured cannibalisation rate. If not, use industry benchmarks:

Strong brand with minimal competition: 70-80% cannibalisation
Moderate brand with some competition: 55-70% cannibalisation
Weak organic presence or heavy competition: 40-55% cannibalisation

Step 3: Calculate waste

Monthly brand spend x cannibalisation rate = monthly waste

Step 4: Calculate opportunity cost

Monthly waste / non-brand CPA = missed new customers per month

Step 5: Add agency fees (if applicable)

Monthly brand spend x agency fee percentage = agency fee on brand spend

Step 6: Sum the true cost

Monthly waste + opportunity cost (valued at customer lifetime value) + agency fee on brand spend = true monthly cost

Worked example

| Input | Value | |---|---| | Monthly brand campaign spend | £3,500 | | Average brand CPC | £0.55 | | Monthly brand clicks | 6,364 | | Estimated cannibalisation rate | 65% | | Non-brand CPA | £40 | | Average customer lifetime value | £800 | | Agency fee | 12% |

| Calculation | Result | |---|---| | Monthly waste (£3,500 x 65%) | £2,275 | | Missed new customers (£2,275 / £40) | 57 customers | | Missed lifetime value (57 x £800) | £45,600 | | Agency fee on brand spend (£3,500 x 12%) | £420 | | True monthly cost (waste + agency fee) | £2,695 | | True annual cost | £32,340 | | Annual missed customer lifetime value | £547,200 |

The surface cost of this brand campaign is £3,500 per month — or £42,000 per year. But the true economic impact, including the opportunity cost of missed acquisitions, runs into six figures.

What good looks like

Not all brand spend is waste. A well-managed brand campaign with genuine incrementality can be one of the most efficient campaigns in your account. The goal is not to eliminate brand spend but to right-size it.

Healthy brand campaign indicators:

Brand spend is less than 8% of total Google Ads budget
You have measured incrementality and know your actual rate
Brand CPCs are appropriate for your competitive landscape
You actively monitor Auction Insights and adjust bids based on competitive conditions
PMax has brand exclusions enabled
Brand campaign budget increases only when competitor activity increases

Warning signs of excessive brand spend:

Brand spend exceeds 15% of total Google Ads budget
You have never tested incrementality
Brand CPCs have increased significantly over the past year
Brand campaign is the "best performing" campaign in the account (this almost always means it is cannibalising organic)
PMax does not have brand exclusions

Industry-specific considerations

E-commerce and retail

Online retailers often face brand bidding from comparison shopping sites, marketplace sellers, and direct competitors. Brand CPCs tend to be lower than in services industries, but the volume is higher. The absolute waste can be substantial.

Key consideration: If you sell on Amazon, eBay, or other marketplaces, those platforms may bid on your brand name. This is harder to address because they are legitimate retailers of your products.

SaaS and technology

SaaS companies face aggressive brand bidding from direct competitors. The "alternatives to" and "vs" keyword patterns are especially competitive. Brand campaign incrementality tends to be moderate (40-60%) because users in the software evaluation phase are more likely to click competitor ads.

Key consideration: High customer lifetime values in SaaS mean the opportunity cost of misallocated brand spend is amplified. Redirecting £2,000/month from brand to non-brand could acquire customers worth £100,000+ over their lifetime.

Financial services and insurance

These industries have the highest brand CPCs due to intense competition and high customer values. Brand campaign waste is proportionally similar to other industries, but the absolute numbers are much larger.

Key consideration: Regulatory requirements may influence your brand campaign strategy. Some financial brands run brand campaigns partly to ensure compliant messaging appears at the top of SERPs.

Local services

Local businesses often face brand bidding from national competitors, aggregators, and lead generation sites. Brand search volumes are lower, but the impact per lost click is higher because each customer represents significant revenue.

Key consideration: Google Business Profile optimisation is disproportionately valuable for local brands. A complete profile with reviews provides strong brand SERP coverage that reduces dependency on paid brand ads.

Taking action

Understanding the true cost of your brand campaign is the first step. The next steps are practical:

Audit your current spend. Use our brand spend calculator to quantify waste with your actual numbers.
Test incrementality. Follow our step-by-step guide to measure what your brand campaign actually delivers.
Optimise or eliminate. Based on your incrementality data, either optimise your brand campaign for efficiency or redirect the budget to growth campaigns.
Monitor ongoing. Set up SERP monitoring to track competitor activity and adjust your brand strategy as conditions change.
Get a baseline. Request a free brand audit for an independent assessment of your brand's search exposure, competitor activity, and estimated waste.

The true cost of brand campaigns is almost always higher than advertisers expect. But that also means the savings opportunity is larger than expected. Every pound moved from non-incremental brand spend to genuine acquisition activity is a pound working harder for your business.
