Google Ads vs Meta Ads UK 2026

Everyone asks this question sooner or later. Should we spend on Google Ads or Meta Ads? Which one works better in the UK in 2026? The honest answer is: it depends, and anyone who tells you otherwise is selling something.

We run both at Dedote for London and UK clients across ecommerce, B2B and services. We've watched the same £3,000 monthly budget produce very different outcomes on the two platforms depending on what the client sells, who they sell it to and how patient they are.

This article is the version of the conversation we usually have with clients on the discovery call. What each platform is actually good at. Where they overlap. Which one to pick if you can only afford one. And where the received wisdom is wrong. You'll get honest opinions rather than a Wikipedia-style balance. We prefer the format because it saves time.

1 · What is the actual difference between Google Ads and Meta Ads in 2026?

Google Ads catches people who are already searching for something. Meta Ads (Facebook, Instagram, Messenger, Threads) puts you in front of people scrolling their feeds who haven't asked for anything specific. That's the entire difference in one sentence, and everything else follows from it.

Per Google's 2024 UK Search Ads Report, 76 percent of UK consumers who click a Google Ad convert within 24 hours. Per Meta's 2024 UK Attribution Study, most Meta Ads conversions arrive across a 7 to 28 day window because the person needs to be reminded and nudged. Two totally different funnels.

That's why the choice matters. Get it wrong and you're spending budget on the wrong problem.

2 · Which is cheaper per click in the UK?

Meta wins on click cost. Per WordStream's 2024 UK Google Ads Benchmark, average UK Cost Per Click on Google runs £1.40 to £4.20 depending on the niche. Legal, dental and insurance sit at the higher end. Per Statista's 2024 UK Meta Advertising Report, average Meta CPC in the UK sits at £0.50 to £2.80 for the same-ish niches.

But cheap clicks aren't the point. Cost per acquisition matters more than cost per click, and Google Ads often wins on CPA despite the higher CPC because the intent is stronger. We've seen retail clients pay £3.50 per Google click and £0.80 per Meta click, then discover Google converted at 4 percent and Meta converted at 0.7 percent.

Do the arithmetic. Cheaper isn't always cheaper.

3 · Where the intent difference really matters

Google is intent. Meta is interruption. That's not a criticism of Meta. Interruption at the right moment is how most brand awareness happens in 2026.

If your product solves a known problem that people search for, Google Ads is the shorter path. Emergency plumber, divorce solicitor, orthodontist, urgent IT support. Anything where the person types the exact thing they need into Google. Google gets your ad in front of them and they buy.

If your product creates the desire rather than answering it, Meta wins. New skincare brand, subscription box, novelty gift, artisan food. Nobody wakes up and Googles "artisan miso paste in wooden pot." They see it on Instagram, they want it, they buy it. Google would never have found them.

Some businesses genuinely need both. A high-value course? Meta creates the interest. Google captures the branded search when the buyer looks for reviews before buying.

4 · Which platform suits ecommerce better?

Honest answer: usually both, but Meta wins if you have to pick one for pure DTC brands.

Per Shopify's 2024 UK Merchant Report, 71 percent of UK Shopify stores over £500k annual revenue run both Google and Meta as primary paid channels. Google Shopping and Performance Max handle the buyer who already knows what they want. Meta Advantage+ Shopping Campaigns handle the buyer who didn't know your brand existed until 90 seconds ago.

For very established ecommerce brands with strong branded search, Google delivers more efficient ROAS. For newer or discovery-led brands, Meta typically delivers more incremental revenue because you're literally creating the market. We've watched a new UK skincare brand hit £40,000 monthly revenue almost entirely from Meta in month three because Google Ads had no demand to capture yet.

Shopify data plus Klaviyo email plus Meta Ads is the modern DTC stack. Google plugs in once branded search takes off.

5 · Which platform suits B2B and service businesses better?

Google wins for most UK B2B and services. Not close.

A commercial plumber in Croydon can spend £2,000 a month on Google Ads and see leads within a week. That same £2,000 on Meta would produce a lot of impressions but very few actual enquiries because "commercial plumber Croydon" isn't something people scroll Instagram hoping to find.

LinkedIn Ads (Microsoft-owned, technically not Meta) is the B2B interruption channel that works. Meta itself is stronger for high-consideration B2B where the audience genuinely spends time on Facebook or Instagram (small business owners, freelancers, tradespeople) but weaker for enterprise B2B where LinkedIn's targeting wins.

Per LinkedIn's 2024 UK B2B Benchmark Report, median UK B2B cost per qualified lead runs £180 to £600 on LinkedIn against £120 to £450 on Google Search for the same audiences. Neither is bad. Both beat trying to run enterprise B2B on Meta.

6 · What if we can only afford one?

We get this question weekly. The answer depends on what you sell.

If you sell to people who already know they need it: Google Ads. Full stop. Legal, medical, emergency services, high-cost repair, professional services, most B2B, any query where a customer types "[thing I need] near me." Google captures existing demand.

If you sell to people who don't know they need it yet: Meta Ads. New product categories, discretionary spend, discovery-led ecommerce, most consumer brands, anything that benefits from being seen rather than searched. Meta creates demand.

If your product sits between the two (established consumer brand with search intent plus discovery upside): pick Google if budget is under £2,500 per month and Meta if budget is over £5,000 per month. Between those numbers it's a judgement call. Per our Dedote 2026 client data, brands under £30k monthly revenue benefit more from concentrated spend on one channel than split spend across both.

7 · Should we run both together?

Eventually, yes. Almost every UK client we work with ends up on both once they can afford it. But not on day one.

Per Google's 2024 Cross-Channel Marketing Report, brands running Google plus Meta together see 34 percent higher blended ROAS than brands running either alone, because the two channels close different parts of the funnel. Meta creates awareness that Google captures at the branded-search stage. Google gets more efficient over time as branded searches grow. Meta gets more efficient over time as the pixel learns your buyers.

The mistake is running both badly on a small budget. Split £1,500 a month across both platforms and you'll get thin results on both. Concentrate £1,500 on one, prove it works, then layer the second channel in once cash flow allows.

8 · Common mistakes we see on each platform

Google Ads: broad match with no negative keywords, no conversion tracking, running one campaign for every ad group. This wastes 30 to 50 percent of spend on irrelevant terms. Fix: single-theme ad groups, weekly search-term reviews, aggressive negatives.

Meta Ads: reused creative across formats, no Conversions API, targeting audiences smaller than 500,000. Meta's algorithm needs volume and creative variety. Fix: creative refresh every 2 to 4 weeks, CAPI setup, broad audiences that let Advantage+ do its job.

The most common mistake on both is running the ads and not touching the landing page. Ad performance depends on landing page conversion rate at least as much as ad quality. If your landing page is slow or badly written, no amount of bid tuning fixes it.
