Paid social vs Google Ads: which channel earns more for UK SMEs?

Google Ads and paid social are often treated as alternatives — as if you pick one and dismiss the other. For a UK small business they aren't. They do different jobs. Mis-selling either as a standalone 'marketing solution' is how budgets get wasted. Understanding what each is actually for is how budgets start working.

What each channel is actually good at

Google Ads catches intent. Someone has just typed 'emergency boiler repair Chelmsford' into a search bar — they have money in hand, they want a solution now, and the question is only 'who'. Ads put you in front of that question at the moment it's being asked. Conversion rates are high; volume is low but beautifully qualified.

Paid social creates intent. Your future customer is scrolling Instagram on the sofa and isn't thinking about your product until an ad appears that makes them think about it. Paid social is where you build awareness, consideration, and eventually conversion — but you have to work harder on creative because you're interrupting, not answering.

Rough cost-per-lead ranges for UK SMEs (2026)

• Google Ads — local service businesses: £15–£60 per lead depending on how competitive your postcode is.
• Google Ads — B2B services: £40–£150 per lead. Higher intent, lower volume, higher value.
• Meta (Facebook + Instagram) — local B2C: £8–£35 per lead with decent creative.
• Meta — B2B: rarely makes sense unless you're running very specific retargeting.
• TikTok — B2C with video-friendly products/services: £5–£25 per lead, but demands steady creative output.
• LinkedIn — B2B only: £60–£250 per lead. Expensive but the audience is decision-makers by job title and seniority.

These are genuine ballparks, not promises. Your industry, geography, creative quality and landing-page strength all move these numbers significantly.

When paid social clearly wins

• You sell B2C and your product photographs, films or demonstrates well.
• You're launching something new and need to seed awareness before anyone is searching for it by name.
• You have a niche audience with strong demographic signals — interests, life stage, behaviours — that Meta can target.
• Your average order value is small, and you need volume to make the unit economics work.

When Google Ads clearly wins

• You sell to people with an urgent problem — trades, emergency services, appointment-based B2C.
• Your product or service solves a pain that people Google by name.
• You need measurable revenue within 30–60 days, not a six-month brand-building curve.
• You sell B2B and your buyers are actively researching vendors.

How we usually recommend splitting budget

For a typical UK service business with a £1,500/month paid-media budget, the right split is usually 60/40 or 70/30 in favour of Google Ads. Ads catch the demand you can buy today; a smaller paid-social budget builds the audience that will Google you in six months. Scale the social side up as you develop creative that works; scale the Ads side up as conversion tracking proves out which campaigns return the most.

“The businesses that get this right stop thinking in 'which channel' and start thinking in 'which job needs doing' — then choose the channel that does that job best.”
