Every week someone asks us a version of the same question. They have been running Google Ads for three months, they have spent a few thousand pounds, and they cannot tell whether it is working. Or they have never run ads at all and they have heard two opposite stories from two people they trust.
So here is the honest answer, without the sales pitch.
The short answer
Google Ads is worth it in 2026 if you have three things: a product or service people are already searching for, gross margins healthy enough to pay for a click and still make money, and a website that converts the traffic once it lands.
Miss any one of those and Google Ads will not save you. It will just find out faster that something is broken.
That is the real function of paid search. It is not a growth channel so much as an accelerant. It makes a good business grow quicker and it makes a weak funnel bleed quicker.
What a click actually costs in the UK right now
Average cost per click across all UK industries sits at roughly £2.50, though published UK benchmark studies put it anywhere between £1.95 and £3.65 depending on whose dataset you read.
The average hides everything that matters though. Real UK CPCs in 2026 look more like this:
- Charity and non profit: under £1
- Local trades: £1.50 to £3
- Ecommerce and retail: £1.50 to £4
- B2B SaaS: around £3.65
- Legal services: £8 and up, and closer to £12 for competitive London terms
Location moves it too. Greater London CPCs run 15 to 30 percent above the same keyword in Leeds, Glasgow or Cardiff.
So when someone says Google Ads is expensive, the honest reply is: expensive relative to what you make per customer. A £9 click is cheap for a conveyancing firm with a £1,500 fee. A £2 click can be ruinous for a store selling £14 candles.
The uncomfortable trend nobody is putting in their case studies
Here is the bit most agency blogs skip.
Between August 2025 and July 2026, click through rates on Google Ads went up by around 7.5 percent. Conversion rates went down in 13 of 14 industries tracked. Those figures come from WordStream’s 2026 Google Ads benchmark study.
Read that again. More people are clicking. Fewer of them are buying.
Google’s AI driven matching has got better at putting your ad in front of someone who is interested enough to click. It has not made that person more likely to buy from you. The bottleneck moved. It used to sit in the ad account. In 2026 it sits on the landing page.
Which means a lot of the businesses currently concluding “Google Ads does not work for us” have actually got a conversion problem wearing a paid media costume. If you have not looked at your product and landing pages in the last year, that is where the money is going. Our ecommerce conversion optimisation tactics post covers the fixes that move the needle first.
For context, average Search Network conversion rates in 2026 land somewhere between 3.75 and 8.18 percent depending on the dataset and how conversions are defined, according to 2026 figures published by WordStream and Search Engine Journal. Ecommerce specifically sits near 2.81 percent. If you are at 1 percent, you have a page problem, not a platform problem.
When Google Ads is genuinely worth it
Say yes if most of these describe you.
People search for what you sell. There is existing demand with intent behind it. “Emergency plumber Manchester” is demand. “Innovative wellness ecosystem” is not.
Your gross margin is above roughly 30 percent. Below that, the maths gets very tight very quickly. See the calculation below.
Your average order value or deal value is high enough to absorb a few clicks. If it takes 40 clicks at £2 to make one £60 sale, you are losing money before you have paid for anything else.
You can track a conversion properly. Not “form views”. An actual enquiry, call or purchase, tied back to a campaign. Without this you are guessing with a credit card.
You have budget for at least 90 days. Anything shorter and you are paying for the learning phase and then leaving before you get the benefit of it.
Your competitors are bidding. Annoying, but it is a signal. Nobody sustains an unprofitable campaign for two years.
When it is honestly not worth it
Say no, or wait, if any of these are true.
You are selling something nobody searches for yet. New category products need demand creation. That is Meta, TikTok and content, not search. We cover that split in our Meta Ads guide for DTC brands.
Your budget is under about £500 a month in a competitive vertical. At a £6 CPC that is 83 clicks. You will not gather enough data to optimise anything. You will just fund a very small experiment that never reaches significance.
Your site converts under 1 percent and you are not fixing it. Paid traffic into a leaking funnel is the most expensive way to learn your site has a problem.
You need results this month to survive. Paid search is faster than SEO, but the first four to six weeks are largely data gathering. It is not a rescue plan.
Your margins are thin and fixed. Grocery, commodity resale, anything where you compete on price against someone with better buying power. The auction will find your ceiling fast.
The one calculation that settles the argument
Forget opinions. Work out your break even.
If you sell products
Break even ROAS = 1 ÷ gross margin
A 40 percent margin gives you a break even ROAS of 2.5. Every £1 of ad spend has to return £2.50 in revenue just to stand still. Anything above that is profit, anything below is you buying revenue at a loss.
If you sell services or generate leads
Maximum cost per lead = deal value × gross margin × close rate
A £4,000 project, 50 percent margin, closing one in five enquiries, gives you £400 as your absolute ceiling per enquiry. If your CPA comes in at £150, Google Ads is working. If it is £600, it is not.
Run that number before you run the campaign, not after. Most of the “is it worth it” arguments we get pulled into are really arguments about a break even figure nobody ever calculated. If you want to go deeper on the revenue side of this, our guide on what a good ROAS actually looks like breaks down the benchmarks by category.
What actually changed in 2026
Three things worth knowing before you decide.
AI Max is arriving whether you asked for it or not. From September 2026 Google began automatically migrating campaign level broad match and automatically created assets over to AI Max. Dynamic Search Ads follow in February 2027, a date Search Engine Land reported after Google pushed the deadline back. Google’s own announcement claims around 7 percent more conversions at similar CPA when the full feature set is used. Our read is more cautious: it works well for accounts with clean conversion tracking and strong landing pages, and it burns budget faster in accounts without them.
Performance Max still needs supervision. It is not a set and forget campaign, whatever the interface implies. Brand exclusions, asset group discipline and proper feed hygiene are what separate a PMax campaign that prints money from one that quietly spends it on your own brand traffic. We wrote the full method in our Performance Max optimisation guide.
AI Overviews are compressing organic real estate. Which, ironically, makes paid search more valuable in the short term for commercial queries and makes the case for running both. A single channel strategy is more fragile in 2026 than it was in 2023.
How to test it properly in 90 days
If you are still unsure, do not agonise. Run a controlled test.
- Weeks 1 to 2. Fix tracking first. Server side or enhanced conversions, one primary conversion action, values attached. Nothing else matters until this is right.
- Weeks 1 to 2. Calculate your break even ROAS or maximum CPA. Write it down. This is your pass or fail line.
- Weeks 3 to 6. Run exact and phrase match search on your five clearest commercial intent terms only. No broad match, no PMax yet. You are testing demand, not Google’s algorithm. Our complete Google Ads guide walks through the account structure we use for this.
- Weeks 7 to 10. Add Shopping or Performance Max if you sell products. Our Google Shopping setup guide for UK stores covers the feed side.
- Weeks 11 to 13. Compare against the line you wrote down in week 2. Not against how it feels. Against the number.
Budget realistically. In most UK verticals you want £1,500 to £3,000 a month minimum for that test to produce a readable result. Less than that and you are not testing Google Ads, you are sampling it.
The verdict
Google Ads is worth it in 2026 for most businesses with proven demand, margins above 30 percent, working conversion tracking and a site that converts. For those businesses it remains the most reliable source of high intent traffic available, and the AI changes have made a well run account harder for a competitor to beat on manual effort alone.
It is not worth it for businesses creating a new category, running on thin margins, testing with pocket money, or hoping paid traffic will compensate for a website that does not convert.
The channel is fine. The question is whether your unit economics survive contact with an auction. Do the maths first and the answer usually becomes obvious before you have spent a penny.

Frequently asked questions
Yes, when the search demand exists locally and the margin supports the click cost. Local service businesses with £1.50 to £3 CPCs and jobs worth several hundred pounds tend to see the fastest payback. Small businesses in high CPC verticals like legal or insurance need a bigger test budget to reach a readable result.
In most UK verticals, £1,500 to £3,000 a month for at least 90 days. The figure matters less than the click volume it buys. You need enough clicks to gather statistically useful data, which is why a £6 CPC vertical needs more budget than a £1.50 one.
Expect four to six weeks of data gathering and optimisation before performance stabilises, and 90 days before you can judge it fairly. Accounts with clean conversion tracking and strong landing pages get there faster.
They answer different questions. Google Ads buys immediate visibility and stops when you stop paying. SEO compounds slowly and keeps working. In 2026, with AI Overviews taking organic space on commercial queries, most businesses at scale need both rather than a choice between them.
Most often the landing page, not the ads. Conversion rates fell across 13 of 14 industries in the last year while click through rates rose. Check page speed, offer clarity, form length and mobile experience before you touch the campaign settings.
