How to Maximise ROI with Google Ads & Facebook Campaigns

Introduction

In today’s ever-evolving digital age, online advertising has become a cornerstone of successful marketing strategies. With tech giants like Google and Facebook leading the charge in digital advertising, businesses across the globe are continuously looking for ways to optimize their campaigns and increase return on investment (ROI).

Whether you’re running a B2B SaaS startup or an e-commerce brand, understanding performance metrics such as Cost per Click (CPC), Cost per Conversion (CPCo), and marketing Key Performance Indicators (KPIs) is essential to achieving scalable and sustainable growth.

In this article, we’ll break down the current state of CPC and CPCo in 2025, compare Google and Facebook ad performance, and give actionable tips to help you cut costs, drive conversions, and make the most of your ad spend.

What Is Cost Per Click (CPC)?

CPC refers to the price an advertiser pays each time a user clicks on their ad. The cost varies depending on factors such as industry competitiveness, target audience, ad quality, and ad platform.

• Google Ads CPC in 2025 ranges from £0.80 to £2.50, with industries like finance, legal, and healthcare often hitting the higher end.
• Facebook Ads CPC remains more affordable, typically falling between £0.40 and £1.20, making it a strong choice for businesses targeting wide demographics or running brand awareness campaigns.

Optimizing for a lower CPC allows businesses to reach more users while staying within budget — but clicks alone don’t pay the bills. That’s where CPCo comes in.

What Is Cost Per Conversion (CPCo)?

Cost Per Conversion (also called Cost Per Acquisition) measures how much you’re spending to achieve a desired action — such as a lead, sale, or booking.

• Google Ads average CPCo: £25–£80 depending on your industry and funnel.
• Facebook Ads average CPCo: £15–£50 with more variability based on audience targeting and creative strategy.

For example:

• E-commerce brands may see a CPCo of £30–£50 on Google and £20–£35 on Facebook.
• High-ticket services, like real estate or insurance, can see CPCo exceeding £100.

To reduce CPCo, it’s vital to match your offer with audience intent and ensure your landing page and creatives are fully optimized for conversion.

Key Marketing KPIs You Need to Track

1. Click-Through Rate (CTR)

CTR shows how compelling your ad is. A higher CTR means your ad resonates with your audience.

• Google Ads Average CTR: 2%–3%
• Facebook Ads Average CTR: 0.9%–1.8%

2. Conversion Rate (CR)

Conversion rate reveals how effective your campaign is at turning clicks into customers.

• Google Ads CR: 3%–5%
• Facebook Ads CR: 1.5%–3%

3. Return on Ad Spend (ROAS)

This is the revenue generated for every £1 spent. ROAS benchmarks vary by industry, but a strong ROAS is typically:

• 300% or higher for eCommerce
• 500%+ for lead generation (with high customer lifetime value)

How to Improve CPC, CPCo & ROI in 2025

Here’s how to get more from your ad campaigns on Google and Facebook:

✅ Set Clear Campaign Objectives

Define KPIs from the start: leads, traffic, conversions, or brand awareness. Avoid generic goals and focus on measurable outcomes.

✅ Use Intent-Based Keyword Targeting

For Google Ads, in-depth keyword research is key. Long-tail and high-intent keywords often lead to lower CPC and higher CR.

✅ Refine Audience Targeting

Both platforms offer rich targeting tools. Create lookalike audiences, retarget previous visitors, and exclude irrelevant traffic.

✅ Craft Scroll-Stopping Creatives

High-quality visuals, compelling CTAs, and engaging headlines are essential. A/B test multiple ad versions to find the top performer.

✅ Optimize Your Landing Pages

Ensure fast load speed, mobile responsiveness, clear CTAs, and trust signals like testimonials or guarantees. A poor landing page kills ROI.

✅ Track Conversions Accurately

Set up conversion tracking for key actions: sales, sign-ups, calls, or form submissions. Without accurate tracking, you’re flying blind.

✅ Leverage Remarketing

Re-engage visitors who didn’t convert. Remarketing typically brings a higher ROI and lower CPCo.

✅ Test Everything

Use A/B testing to experiment with ad headlines, targeting, formats, and bidding strategies. Never settle for a “good enough” ad.

✅ Monitor Campaigns Weekly

Review CTR, CPC, CR, and ROAS regularly. Pause underperforming ads, and reallocate budgets toward what’s working.
