Two different products
The comparison is usually set up as two ways of doing the same thing more or less cheaply. It is not. They are two products with different delivery times, different risk profiles and different residual value, and a trade business choosing between them is really choosing between certainty now and ownership later.
Paid search is rented placement. You bid, you appear, the phone rings, and the moment the card stops working so does the traffic. It is fast, meterable and switchable, and its cost per enquiry is set by an auction you share with everybody else who wants that search.
Organic search is earned placement. Nobody bills you per click. Instead you invest in pages, technical health, a Google Business Profile and reviews, and somewhere between three and twelve months later a position starts carrying traffic that keeps arriving after the invoice stops.
To give the market some scale: the IAB UK Digital Adspend study for 2025 put total UK digital advertising at £40.5bn, of which paid search accounted for £17.9bn, roughly 44%. That is a large, mature, professionally contested auction. You are not going to find a corner of it nobody has noticed. What you can do is be more disciplined inside it than the firms you are bidding against.
One more difference matters and is usually left out of the comparison: what each channel does to the rest of your marketing. Paid search is self-contained. Turn it on, measure it, turn it off, and nothing else in the business changes. Organic is not. Ranking properly requires the site to be fast and structured, requires a page for each service you want work in, requires the Google Business Profile to be complete and requires a habit of collecting reviews. All of that also improves conversion on paid traffic, on referral traffic, and on the person who was given your name in a pub. The organic investment is therefore partly an investment in everything else, which is an argument for starting it earlier than pure cost-per-enquiry arithmetic would suggest.
Cash flow decides this, not preference
Ask the question this way instead: how many months can your business survive spending money on marketing before that marketing produces a job?
If the answer is measured in weeks, the decision is already made. SEO cannot deliver inside that window and no honest practitioner will claim it can. Paid search will have enquiries in the first week and useful data in about four, because the people searching for your trade are already searching for it and you are simply buying a place in front of them.
If the answer is measured in quarters, and you have existing work keeping the lights on, then investing in ground you own while you can afford the wait is a genuinely better use of the same money. The firms that regret starting with SEO are almost always the ones that could not afford the gap and had to abandon it halfway, which is the worst of both: the cost of the wait without the reward at the end.
Three secondary factors move the decision, in roughly this order of importance.
- Urgency of the work you sell. Emergency trades live at the top of the results at the moment of panic. Being third organically for a burst pipe is worth less than it looks.
- Job value. High job values give paid search headroom to absorb an expensive click. Low job values push you towards channels without a per-click cost.
- Existing assets. A firm with a decent site, a mature Google Business Profile and sixty reviews is much closer to organic results than one starting from a single page and no profile.
How the cost behaves over two years
The reason sequencing matters is that the two cost curves are shaped differently. Paid is close to flat: spend the same, get roughly the same, improving somewhat as the account learns. Organic is a long negative slope: it costs before it pays, then it pays without costing per enquiry.
| Point in time | Paid search | SEO and Google Business Profile |
|---|---|---|
| Week 1 | Live. First enquiries usually inside seven days. Cost per enquiry volatile and not yet a signal. | Nothing visible. Technical fixes, page structure and profile work underway. |
| Month 1 | Enough conversion data to start cutting waste. The search terms report is teaching you what you did not know. | Map pack movement possible if the profile was neglected. Little else. |
| Month 3 | Cost per enquiry settling. You should be able to name the keywords doing the work. | Movement on longer, specific searches. Rarely on the main money term yet. |
| Month 6 | Predictable volume at a known cost. You can plan hiring around it. | Meaningful weight starting to appear. Some enquiries arriving with no click cost attached. |
| Month 12 | Stable. Costs broadly track the auction, which does not usually get cheaper. | Carrying a real share of enquiries. The investment made in month one is still working. |
| If you stop | Traffic ends the same day. | Decays slowly over months. You keep the ground for a while. |

Note the last row, because it is the whole argument. Paid search is a tap. Organic is a well. Firms in a hurry need a tap; firms building something want a well; most firms need both and are simply arguing about which order to dig in.
When SEO genuinely goes first
We would put organic ahead of paid in these cases, and have.
- Your clicks are brutally expensive and your margin is thin. Some trades in some cities have auctions dominated by national lead resellers who can pay more for a click than you can, because they sell the resulting enquiry several times. Competing head-on is a bad trade; ranking for the specific searches they cannot be bothered to write pages for is a good one.
- Your work is researched, not urgent. Extensions, garden rooms, full rewires planned around a renovation. People read for weeks before enquiring, and pages that answer real questions collect them.
- You already rank a bit. A site with some history and a profile with reviews can move faster than a standing start, and the marginal cost of getting from page two to the top three is often modest.
- Your diary is full for the next quarter. The best moment to invest in a slow channel is when you do not need it, which is exactly when nobody does it.
When paid genuinely goes first
The opposite cases are just as clear.
- You need work inside a month. There is no argument here.
- Your trade is emergency-led. Leaks, lockouts, blocked drains, power faults. The buying decision happens in minutes and position matters more than reputation.
- You do not yet know what converts. This is the underrated one. A month of search terms data tells you what people actually type, what they actually want and which jobs they are actually worth, which is exactly the research an SEO plan needs and rarely has. Paying for that knowledge quickly is usually cheaper than guessing it slowly.
- You are testing a new service or a new area. Ads can prove demand in a fortnight. Writing pages to find out takes two seasons.
The sequencing answer
For most trade firms with normal cash flow, the order that works is paid first, organic second, funded by the first.
Start narrow on search advertising and get to a known cost per enquiry. Use the search terms report as free market research: it tells you which services, which phrasings and which towns produce quoted work rather than idle clicks. Then build the organic programme against that evidence instead of against a keyword tool’s guesses, so the pages you write are the pages the data already says convert.
As organic starts carrying enquiries, the paid budget does not usually go down. It moves. Spend shifts off the terms you now rank for and onto the ones you do not, or onto a new service line, or into a neighbouring town. The combination is more efficient than either alone because each channel is doing the thing it is good at.
One practical warning. Both channels sit on the same landing pages, so a site that converts badly wastes both budgets simultaneously. If your enquiry rate is poor, fixing the site before increasing spend is almost always the higher return. And whichever channel you start with, the enquiry has to be answered fast at the other end, which is what follow-up automation is for. Buying attention into a leaking process is the most reliable way to conclude that marketing does not work.
When the answer is neither
Some businesses should not start with search at all, and we would rather say it here than three months into a retainer.
If nobody searches for what you do, search marketing has nothing to capture. Genuinely new categories, or work that arrives through specification and relationships rather than demand, need a different approach. If your average job is worth £120 with a one-in-six close rate, the profit per enquiry will not cover a contested click and probably will not cover the cost of producing content either. And if the searches exist but they are all in a town you cannot profitably reach once travel is priced, the volume on the screen is not volume you can use.
In those cases the honest advice is repeat business, referral routines, reviews and, sometimes, a lead platform absorbing the acquisition risk instead of you. How we test for this before anything is spent is set out on the methodology page, and the sector-by-sector economics are on the industries pages. If the numbers say no, that is a twenty-minute conversation, not a three-month experiment.
Want this decided on your numbers rather than in the abstract?Average job value, close rate and the area you cover. That is enough to say which of these is right for you, including when the answer is neither.

Which is cheaper, Google Ads or SEO?
Over three months, paid search. Over three years, organic, if it works. Paid has a permanent cost per click and no residual value; SEO has a large up-front cost in work and time, then delivers enquiries without a click cost. Comparing them over the wrong period is how people reach confident wrong conclusions.
How long does SEO take for a trade business?
Three months before you see movement is normal, six to twelve before it carries meaningful weight. Google Business Profile work can move faster than that if the profile has been neglected, because there is usually low-hanging fruit. Anyone promising rankings in weeks is describing something other than competitive local search.
Can I do both from the start?
Yes, and if the budget genuinely supports both without starving either, it is the strongest position. The failure mode is splitting a small budget so thinly that the paid account never gathers enough conversion data to optimise on while the organic work is too shallow to rank. Two half-funded channels beat neither.
Does running Google Ads improve my organic rankings?
No. There is no direct ranking benefit and Google is explicit about that. The indirect benefit is real but different: the search terms report shows you exactly what people type and which of those searches produce quoted work, which is far better raw material for an SEO plan than keyword tool estimates.
What if I stop paying for ads?
Traffic stops the same day. That is the honest cost of a rented channel, and it is the strongest argument for building organic alongside it rather than instead of it. What you keep either way is the account and its conversion history, which is yours.
