Paid search guide
A click on 'personal injury solicitor' costs £62.39; a click on 'running shoes' costs 57p. Knowing why that gap exists, and how management fees stack on top, is what separates a sensible Google Ads budget from an expensive guess.
The Short Answer First
Google Ads has two separate costs, and mixing them up is one of the most common mistakes business owners make when budgeting.
The first is ad spend: the money you pay Google directly every time someone clicks your ad. You set this budget yourself; Google never charges you more than you authorise.
The second is a management fee: what you pay an agency, freelancer, or consultant to build and run the campaigns. This is an entirely separate line on your invoice.
Understanding the google ads cost you're actually committing to means looking at both figures clearly, then deciding whether the return justifies them. This article breaks both down, gives you a framework for setting a sensible starting budget, and helps you decide who should run your account.
How Google Charges You for Ads
The auction and cost per click
Every time someone searches on Google, an instant auction runs behind the scenes. Advertisers bid on keywords (phrases that trigger their ads) and Google decides which ads to show, and in what order, based on two things: how much you bid, and how relevant your ad and landing page are to the searcher.
You pay cost per click (CPC), a charge only when someone actually clicks. If your ad appears but nobody clicks, you pay nothing.
Quality Score: why relevance saves you money
Google assigns each keyword a Quality Score from 1 to 10, based on the expected click-through rate of your ad, how relevant your ad is to the keyword, and the experience people get when they land on your page.
A higher Quality Score means Google charges you less per click for the same position. Two advertisers can bid identically and pay very different amounts, simply because one has a better-structured campaign and a faster landing page. This is why account management matters beyond just setting bids.
Why some clicks cost far more than others
CPCs vary enormously by sector. Legal, financial services, and insurance keywords are historically among the most expensive in the UK: solicitors and insurers compete fiercely for high-value customers, pushing prices up. Local trade searches (a plumber in a mid-sized town, for example) often cost considerably less, because fewer advertisers are competing and the customer lifetime value doesn't justify the same aggression.
The main drivers of CPC are competition (how many other advertisers want that keyword), commercial intent (is the searcher ready to buy?), and lifetime customer value in that industry.
For sector-specific CPC benchmarks, WordStream publishes regularly updated industry data that you can use as a reference point before you plan your budget.
To show how wide the range is, here is what advertisers were paying per click in the UK for some everyday searches:

| ppc agency | Marketing services | £41.77 | 1,600 |
| divorce solicitor | Legal | £25.75 | 2,400 |
| seo agency | Marketing services | £20.43 | 4,400 |
| emergency plumber | Trades | £17.34 | 12,100 |
| mortgage advisor | Finance | £13.32 | 14,800 |
| web design agency | Marketing services | £10.81 | 2,900 |
| hair transplant | Health | £9.51 | 22,200 |

The pattern is simple: the more a single customer is worth, the more businesses will bid to reach them. A click on "personal injury solicitor" costs about £62.39 because one case can be worth thousands; a click on "running shoes" costs about 57p.
Setting a Starting Budget That Makes Sense
Work back from what a customer is worth
Start with the economics of your business.
Here's a simple, clearly hypothetical worked example:
| Variable | Example figure |
|---|---|
| Average profit per new customer | £500 |
| Maximum you'd pay to acquire one customer | £100 |
| Realistic website conversion rate | 3% |
| Clicks needed per conversion | ~33 |
| Maximum CPC you can afford | £3.00 |
| Budget needed for 33 clicks | £99 |
| Monthly budget (to get ~10 conversions) | ~£990 |
These numbers are illustrative only, and your actual CPC and conversion rate will differ. The principle is the same: if you know what a customer is worth and what your site currently converts at, you can calculate the ceiling on what a click can cost you.
Giving yourself enough data to learn from
Google's own guidance, and the experience of most practitioners, is that you need a meaningful volume of clicks before the data tells you anything reliable. A campaign with 20 clicks per month cannot tell you what's working.
A practical rule of thumb: aim for enough budget to generate at least 50–100 clicks per month in your first three months. If your target CPC is £2, that's £100–£200 a month minimum to gather useful information. At £5 per click, you'd want £250–£500.
Starting too small delays the point at which you can make informed decisions.
PPC Management Fees: What to Expect
How agencies typically charge
Agencies generally use one of three pricing models:
Percentage of ad spend: a fee calculated as a percentage of what you spend with Google each month. This scales with your activity, which keeps incentives aligned.
Flat monthly fee: a fixed charge regardless of spend. Predictable, but can mean the fee becomes disproportionately large relative to a small budget, or disproportionately small relative to a large one.
Hybrid: a base fee plus a percentage above a spend threshold. Common for mid-sized accounts.
Most agencies also charge a set-up fee for the initial build of a campaign, and many require minimum contract terms.
Our pricing at Sayu, as a worked example
To give you a concrete reference point, here is how our PPC management pricing works, given as one example.
Rolling contract (month-by-month after an initial three months):
- 11% of monthly ad spend
- Minimum fee: £199/month
- Maximum fee: £3,500/month
- No set-up fee
12-month contract:
| Monthly ad spend | Management fee |
|---|---|
| £0–£4,999 | 10% (min £179/month) |
| £5,000–£9,999 | 9% |
| £10,000–£14,999 | 8% |
| £15,000–£19,999 | 7% |
| £20,000+ | 6% (max £2,500/month) |
There is no set-up fee on either contract. Your ad spend goes directly to Google or Microsoft (it never passes through us) and the account stays yours.

Doing It Yourself, Using a Freelancer, or Hiring an Agency
The right choice depends on your budget, your time and your market, and we're happy to help you weigh it up.
Do it yourself if your budget is small (under £300/month in spend), you have time to learn the platform properly, and your market isn't too competitive. Google's own training resources are genuinely useful. The risk is that poor campaign structure will mean you pay more per click than necessary, and waste budget on irrelevant searches.
Use a freelancer if you want hands-on expertise without agency overheads. A good PPC freelancer can be excellent value. The honest downside is that capacity and availability vary, and if they're ill or busy with other clients, your account may go untouched. Ask to see recent results and check what tools they use.
Use an agency if you have a meaningful budget (typically £1,000+/month in spend), want structured account management, and need the work to run reliably without depending on one individual. The right agency will combine strategic input with day-to-day optimisation. The wrong one will set up your campaigns and rarely touch them again.
For businesses that also want to build organic visibility alongside paid, combining SEO and PPC management under one provider can reduce duplication and improve how your data informs both channels.
Is Google Ads Worth It?
When it works well
Google Ads performs best when there is clear, existing demand for what you sell, meaning people are already searching for it. It suits businesses with a reasonable margin per customer, a website that converts visitors into enquiries or sales, and the patience to let the data accumulate before drawing conclusions.
It also rewards speed: unlike SEO, paid search can put you at the top of results on day one, which matters if you're launching a new service or entering a new market.
When it doesn't work
If nobody is searching for your product or service yet, there's no search volume to capture. If your margins are very thin and CPCs in your sector are high, the maths may never work. And if your landing page is weak (slow, unclear, or not mobile-friendly) you'll pay for clicks that never convert.
Most of the waste we find in accounts that come to us is in the ad spend: money going on searches that were never going to buy. Fix that first and the fee usually pays for itself.
Simon PittsFounder & CEO, SayuHow to tell after three months
Three months is the minimum period to form a view. By then you should be able to see:
- Whether your cost per acquisition (CPA) is below your target
- Which keywords and ad variations are driving results
- Whether conversion rate is improving as the campaign is refined
If CPA is tracking in the right direction and volume is there, the case for continuing is straightforward. If you're burning budget with no conversions and no clear reason why, that's the signal to audit the campaign structure and landing page before spending more.
Google Promotional Credit for New Advertisers
If you're a new Google Ads advertiser, you may be eligible for promotional credit from Google, essentially matched spend to help you get started.
Through a Google Premier Partner like Sayu, new advertisers can receive between £380 and £3,000 of Google's promotional credit, depending on how much you spend in your first 60 days. The exact amount is set by Google and subject to its terms and conditions; we can confirm eligibility when you get in touch.
Premier Partner status is held by the top 3% of Google Partners in the UK and is re-evaluated by Google every year. Sayu has held it every year since 2023.
Frequently Asked Questions
Is there a minimum spend on Google Ads?
Google itself has no formal minimum. In practice, you need enough budget to generate a sufficient volume of clicks to learn from, typically at least £300–£500 per month if you want data that means anything within a reasonable timeframe. Agencies often set their own minimum management fees, which effectively creates a floor.
Do I pay Google, or do I pay the agency?
You pay both separately. Your ad spend goes directly to Google (via a card or direct debit linked to your Google Ads account). Your management fee is invoiced by the agency. At Sayu, the account always belongs to you, and we never hold your budget or your data.
What is a good cost per click?
There is no universal answer. A solicitor paying £15 per click for a keyword that leads to a £5,000 case may be getting excellent value. A retailer paying £2 per click on a product with a £10 margin may be losing money. A good CPC depends on your margin and conversion rate.
How quickly will I see results?
You can see traffic from day one. Whether that traffic converts profitably is a different question. Most campaigns need two to three months of optimisation before you can draw reliable conclusions, and longer in lower-volume niches. Setting expectations around three months is realistic and honest.
Can I pause or stop at any time?
On a rolling contract, yes: you can pause or cancel with relatively short notice once any initial period has passed. On a 12-month contract, you're committed for that term. Always read the contract terms before signing, and check what happens to your account and data if you leave.
