The Platform Debate: Context Matters More Than Preference
We manage millions of pounds in ad spend across both Google Ads and Facebook Ads (now Meta Ads) for UK lead generation clients. The question "which is better?" comes up in nearly every initial consultation. The honest answer is that both platforms can deliver excellent results, but they serve fundamentally different roles in the buyer journey, and choosing the right one depends on your market, offer, and sales process.
Rather than giving you a vague "it depends", this article lays out the specific strengths, weaknesses, costs, and use cases for each platform based on our campaign data from 2025 and early 2026.
How Each Platform Reaches Your Audience
Google Ads: Capturing Existing Demand
Google Ads puts your business in front of people who are actively searching for what you offer. When someone types "best mortgage broker in Manchester" or "commercial cleaning services London", they have already identified a need and are looking for a solution. This intent-driven approach means Google leads often convert to customers at higher rates because the prospect is further along in their decision process.
The limitation is reach. You can only capture demand that already exists. If people are not searching for your product or service, or if search volume is low in your niche, Google Ads alone will not fill your pipeline.
Facebook Ads: Creating and Nurturing Demand
Facebook Ads interrupts people while they scroll through their feed, watch Reels, or browse Stories. Your audience is not actively looking for your service, so your creative and offer need to stop them, spark interest, and convince them to take action. This makes Facebook better for awareness-stage campaigns, impulse-driven offers, and reaching audiences who do not know they need your service yet.
The trade-off is lead quality. Because Facebook leads have not self-selected by searching for your service, they tend to be less sales-ready. Your follow-up process needs to be faster and more nurturing to convert them.
Cost Comparison: UK Industry Benchmarks
Based on campaigns we managed in 2025 across UK markets:
- Legal services: Google Ads CPL averaged £45-£85. Facebook Ads CPL averaged £18-£35. However, Google leads converted to paying clients at 2.5x the rate of Facebook leads.
- Home improvements: Google Ads CPL averaged £25-£50. Facebook Ads CPL averaged £8-£20. Conversion rate difference was smaller here, with Google leads converting 1.5x better.
- Financial services: Google Ads CPL averaged £55-£120. Facebook Ads CPL averaged £22-£45. Google leads were significantly more qualified, with 3x better conversion to appointments kept.
- B2B services: Google Ads CPL averaged £35-£75. Facebook Ads CPL averaged £15-£40. Quality varied hugely depending on the targeting approach used on Facebook.
The pattern is clear: Facebook produces cheaper leads, but Google produces leads that are closer to buying. The real question is which gives you a better cost per acquisition (CPA) once you factor in your close rate.
When to Choose Google Ads
Google Ads should be your primary platform when:
- There is strong search demand for your service. Check Google Keyword Planner for monthly search volumes. If people are actively searching, you want to be there.
- Your sales cycle is short. If prospects typically decide within days, Google's intent-driven leads are ideal.
- Your product or service solves an urgent problem. Emergency plumbers, solicitors for time-sensitive matters, and healthcare providers all benefit from capturing search intent.
- You have a limited follow-up capacity. Google leads need less nurturing, so if your sales team is small, these leads are easier to close.
When to Choose Facebook Ads
Facebook Ads should be your primary platform when:
- You are launching something new that people are not yet searching for. Facebook excels at introducing products and services to audiences who fit the profile but have not started looking.
- Your offer is visually compelling or emotionally driven. Home renovations, fitness programmes, cosmetic treatments, and lifestyle products perform brilliantly on Facebook because the visual format sells the transformation.
- You need high lead volume at lower cost. If your sales team can handle higher volume and nurture leads effectively, Facebook's lower CPL gives you more opportunities per pound spent.
- You have strong remarketing content. Facebook's pixel allows sophisticated retargeting sequences that warm leads over time.
The Best Approach: Use Both Strategically
Our highest-performing UK clients use both platforms together. The typical structure looks like this:
- Google Ads captures bottom-of-funnel demand from people actively searching. These campaigns run continuously with aggressive bid strategies on high-intent keywords.
- Facebook Ads builds top-of-funnel awareness and fills the pipeline with prospects who match the ideal customer profile. Lead magnets, educational content, and free consultations work well as offers.
- Facebook remarketing re-engages Google Ads visitors who did not convert, website visitors, and email subscribers. This layer is often the highest-ROI spend in the entire account.
When we layer both platforms for a UK financial advice firm, we saw the overall cost per acquired client drop by 28% compared to running either platform alone. The combination of Google's intent capture and Facebook's awareness building created a pipeline that was both deeper and more qualified.
Key Metrics to Track on Each Platform
Google Ads
- Cost per lead (form submissions and calls)
- Search impression share (are you losing visibility to competitors?)
- Quality Score by keyword
- Conversion rate by landing page
Facebook Ads
- Cost per lead (on-platform and off-platform forms)
- Lead form completion rate
- Frequency (how often the same person sees your ad)
- Landing page view to lead conversion rate
Making Your Decision
Start with the platform that matches your immediate business situation. If you have strong search demand and need qualified leads quickly, begin with Google Ads. If you need to build awareness, test a new offer, or generate volume at lower cost, start with Facebook Ads. Once one platform is profitable, layer in the other to capture the full funnel.
The worst decision is to split a small budget across both platforms before either has enough data to optimise properly. Commit to one, get it working, then expand.
