Most agencies back into Google Ads rather than choosing it. A web client you have looked after for years mentions they are thinking about paid search. Or a competitor starts running ads and your client wants to know why they are not. Suddenly PPC is on the table, and you have to decide how to handle it before someone else offers to.
That decision usually comes down to three roads: hire someone to run ads in-house, send the work to a white-label partner, or have whoever is least busy that week give it a go. I have been on the receiving end of all three for a good while now, mostly as the people agencies call when the third one has quietly gone wrong. So here is an honest look at how they actually compare, rather than a pitch.
The real cost of hiring in-house
On paper, hiring is the obvious answer. Bring the skill in, own it, keep all the margin. In practice the sums are harder than they look.
A genuinely good paid search manager in the UK is not cheap, and the salary is only the start. There is recruitment, the months before they are properly up to speed, holiday cover, training to keep up with a platform that changes every few weeks, and the awkward truth that one person cannot be an expert in everything. Someone brilliant at search campaigns may be shaky on Performance Max or feed management.
The bigger problem is the one nobody mentions in the job advert: keeping them busy. A PPC specialist needs a steady flow of accounts to be worth the salary. If you have three clients on ads, that person is expensive and bored. If you win eight more, they are drowning and you are back to recruiting. Paid search income rarely arrives in the neat, steady stream a full-time hire needs to pay for themselves, and the gap between "too little work" and "too much" is a narrow one to balance a salary on.
Hiring makes sense once you have the volume to keep a specialist genuinely busy and the pipeline to keep them that way. Plenty of agencies get there. Most are a long way off, and hire anyway because it feels like the grown-up option.
The DIY route, and why it bites
The muddle-through approach is more common than anyone admits. An account manager or a designer who is "good with this sort of thing" sets up a campaign between other jobs. It runs. Clicks happen. Everyone relaxes.
The trouble is that Google Ads is very good at looking like it is working while it quietly wastes money. Broad match keywords pull in searches that have nothing to do with the business. Conversion tracking is set up to count the wrong thing, or nothing at all, so the automated bidding is flying blind. Performance Max spends the budget on the easy clicks it can already get for free. None of this shows up on the surface. The dashboard is green, the spend is going out, and it can be months before anyone works out that the enquiries are not following.
By then the client has noticed too. And an account you set up casually to keep a client happy becomes the reason they start shopping around. I see these accounts regularly, and the pattern is almost always the same: not incompetence, just someone asked to do a specialist job in the margins of another one.
