Should you hire a PPC agency or build an in-house paid ads team? It sounds like a simple choice, but it rarely is. An agency gives you access to several specialists without hiring them all. An in-house PPC manager gives your business one person who works closely with your team every day. Both models can work.
The better fit depends on your ad spend, campaign complexity, internal team, need for control and the amount of specialist work your account needs. For a smaller or growing business, a PPC agency can often give access to more PPC skills without the fixed cost of a full-time team. For a larger company with steady advertising demand, complex internal systems and enough work for a dedicated specialist, in-house management can make more sense. This guide compares the real costs, control, capability, speed, risks and workload behind both choices.
PPC Agency vs In-House Management at a Glance
Here is the simple comparison.
| Factor | PPC Agency | In-House PPC Manager |
| Main cost | Monthly management fee | Salary plus employment costs |
| Team depth | Access to several specialists | Usually one dedicated person |
| Daily focus on your brand | Shared across clients | Fully focused on your business |
| Scaling campaigns | Usually easier | May need more hiring |
| Business knowledge | Must be learned | Usually deeper |
| PPC knowledge | Broad across accounts and sectors | Depends on the employee |
| Recruitment | Not usually required | Required |
| Staff absence risk | Lower with a team | Higher with one specialist |
| Direct control | Good, but external | Very high |
| Tools and software | Often included or already available | Business may need to buy them |
| Best fit | Small, growing and multi-channel businesses | Larger businesses with steady PPC workload |
There isn’t a universal winner. The right choice depends on what your account actually needs.
What Is a PPC Agency?
A PPC agency is an external company that manages paid advertising for several clients. Instead of hiring one employee, you normally pay a monthly management fee for access to the agency’s service. Depending on the agency, that service may include Google Ads, Microsoft Ads, paid social, Shopping, Performance Max, tracking, landing-page advice, feed management and reporting. The important difference is team depth.
Your account may have a main PPC manager, but that person can often call on other people for tracking, creative work, landing pages or technical problems. That can be useful when a campaign becomes more complex.
What Does In-House PPC Management Mean?
In-house management means someone inside your business manages the advertising. This might be a dedicated PPC Manager, Paid Media Manager or broader Digital Marketing Manager. Their working day belongs to your company. They can speak directly with sales, finance, product, customer service and management teams.
That gives them close access to what is happening inside the business. The trade-off is that the company carries the employment cost and depends heavily on the skills of the person hired.
PPC Agency vs In-House: Which Costs More?
This is where businesses often make an unfair comparison. They compare a PPC agency’s monthly fee with an employee’s monthly salary. That leaves out part of the real in-house cost. According to Indeed’s current London salary data, the average base salary for a PPC Manager is about £41,663 per year. Indeed reports a typical London range of roughly £32,247 to £53,828, depending on experience and employer.
You can check the current figures on Indeed’s PPC Manager salary page for London. That is the base salary alone. An employer may also need to cover National Insurance, pension contributions, recruitment, training, paid leave, software and equipment. These extra costs matter when comparing an agency with an employee.
HMRC publishes the current employer National Insurance contribution rates and thresholds on GOV.UK. You can check the latest rates through the official National Insurance contribution rates guidance. Eligible employees can also create workplace pension costs. GOV.UK explains employer responsibilities and minimum pension contributions in its workplace pensions guidance. So the fair comparison is:
Agency management fee vs total employment cost
If you want to understand agency pricing first, read how much does PPC management cost in London?
Example PPC Agency Cost
Imagine your business pays: PPC management: £1,200 per month Annual management cost:
£1,200 × 12 = £14,400
Your actual advertising budget would normally sit separately from that fee.
Example In-House Cost
Now imagine you hire a PPC Manager at £42,000 per year. The real cost does not stop at £42,000. You may also have employer National Insurance, pension contributions, software, equipment, training and recruitment costs. If that employee needs support with design, copy, analytics or development, those costs may sit elsewhere in the business.
This does not mean an agency is always cheaper. Once your paid advertising operation becomes large enough, a full-time internal specialist may offer very good value. The question is whether you have enough ongoing work to justify that fixed cost.
The Real Difference Is Capability, Not Just Cost
Price matters, but capability matters more. A PPC account can involve several different skills. Someone may need to understand keyword intent, bidding, search terms, conversion tracking, product feeds, landing pages, reporting and commercial numbers. A single person can be strong across many of these areas.
But very few people are experts at everything.
PPC Agency Capability
A PPC agency can spread campaign work across several specialists. A paid search specialist might handle Google Ads. A tracking specialist might fix conversion measurement. A developer may help with landing-page problems.
A designer may support Display or paid social campaigns. This wider skill pool can become useful as an account grows.
In-House Capability
An in-house PPC manager may not have the same team depth, but they gain something agencies sometimes struggle to match. Context. They hear what customers are saying. They know which products create the best margins.
They know when stock is running low. They can sit with sales teams and hear why certain leads do not convert. That daily business knowledge can improve campaign decisions.
Control: Where In-House PPC Has an Advantage
Businesses often choose in-house management because they want more control. That is a fair reason. An internal employee can usually respond quickly to company changes. Imagine a London property business needs to stop advertising one development this morning and move budget to another.
An in-house manager can speak with the team and make the change straight away. There is less distance between the decision and the person running the ads. An agency can still respond quickly, but there may be account-management steps or agreed communication times. That difference matters most when campaigns change several times each day.
Where a PPC Agency Can Give More Flexibility
Agencies usually have an advantage when workload changes. Imagine a retailer doubles its advertising before Christmas. The account suddenly needs more campaign work, creative input and reporting. An agency may be able to move more team resource onto the account.
An in-house company cannot instantly turn one PPC Manager into three. It may need freelancers, contractors or new employees. The opposite is also true. If advertising activity drops for three months, an agency package may sometimes be reduced.
A full-time employee remains a fixed business cost.
How Much Attention Will Your Account Get?
This is one of the biggest concerns with agencies. Your business is not their only client. That is true. A poor PPC agency may spread its account managers too thinly. The result can be slow replies and accounts that receive little attention. That is why businesses should ask who will actually manage the account and how often optimisation takes place. In-house management avoids that problem because the employee works only for your company. However, having full-time attention does not automatically mean the campaigns will perform better.
Skill still matters. Someone can spend forty hours each week inside one account and still make poor decisions. The right question is not only:
How many hours do we get?
It is also:
What useful work is being done during those hours?
Account Complexity Matters More Than Business Size
A large company can have a simple PPC account. A small company can have a very complicated one. That is why headcount or turnover alone should not decide between agency and in-house management. Consider two examples.
A London professional service business may spend £15,000 monthly on a small number of focused search campaigns. A growing ecommerce company may spend £8,000 but manage thousands of products, Shopping feeds, Performance Max, remarketing and seasonal offers. The second account may need far more technical work despite having lower ad spend. That is why account complexity should be part of the decision.
PPC Account Complexity Scorecard
Use this scorecard to judge how demanding your paid media setup really is. Give yourself 0, 1 or 2 points for each row.
| Area | 0 Points | 1 Point | 2 Points |
| Ad platforms | One | Two | Three or more |
| Campaign types | Simple Search | Several campaign types | Search, Shopping, PMax, social and more |
| Locations | One area | Several areas | National or multi-market |
| Products/services | Small range | Several categories | Large or changing range |
| Tracking | Basic forms/calls | Several conversions | CRM, offline and ecommerce data |
| Landing pages | One or two | Several | Constant testing and development |
| Reporting | Simple | Channel reporting | Revenue, CRM and attribution reporting |
| Creative demand | Low | Regular | High and ongoing |
What Your Complexity Score Means
- 0 to 4 points: Your account is fairly simple. A freelancer, smaller agency or capable internal marketer may be enough.Â
- 5 to 10 points: Your account has moderate complexity. You need reliable PPC knowledge, good tracking and regular optimisation.
- 11 to 16 points: Your account is complex. Team depth starts to matter more because one person may struggle to cover every area well. This score does not automatically tell you to hire an agency. You also need to measure how ready your internal team is.
Team Maturity Scorecard
Now look at your business itself.
| Question | No | Partly | Yes |
| Do you have clear monthly sales targets? | 0 | 1 | 2 |
| Do you know your lead-to-sale rate? | 0 | 1 | 2 |
| Do you know your customer value or margin? | 0 | 1 | 2 |
| Can sales give marketing useful lead feedback? | 0 | 1 | 2 |
| Is conversion tracking already reliable? | 0 | 1 | 2 |
| Do you have internal design or development support? | 0 | 1 | 2 |
| Can someone senior manage a PPC employee? | 0 | 1 | 2 |
| Is there enough PPC work for a full-time role? | 0 | 1 | 2 |
What Your Team Maturity Score Means
- 0 to 5 points: Your internal setup is still developing. Hiring one PPC employee may leave them without enough data, support or commercial direction.Â
- 6 to 11 points: Your business has some good systems but still has gaps. Either model could work depending on account complexity.
- 12 to 16 points: Your company has a mature marketing setup. An in-house PPC hire becomes much easier to support properly.
Use Both Scores Together
This is where the decision gets more useful.
| Account Complexity | Team Maturity | Model Worth Considering |
| Low | Low | Freelancer or agency support |
| Low | High | In-house can work if workload justifies it |
| High | Low | Agency can provide access to missing specialist skills |
| High | High | Agency, in-house team or hybrid model can all work |
The scorecard is not a strict rule. It helps uncover the gaps behind your decision. For example, you may think you need an in-house PPC Manager because your advertising spend is growing. The scorecard may show that your bigger problem is poor sales tracking.
Hiring someone does not automatically fix that.
What Happens When Your PPC Manager Is Away?
This is a small point until it becomes a big one. An in-house PPC operation built around one person can create a single point of failure. That employee can take annual leave, become ill or resign. They may also hold account knowledge that nobody else fully understands.
An agency normally has more cover because several people can access the account. However, you should still ask how handovers work. A good agency should not leave your entire strategy inside one account manager’s head.
Recruitment Can Change the Cost Calculation
Hiring a good PPC specialist takes time. You need to advertise the role, interview candidates and judge technical ability. That last part can be difficult when nobody inside the company already understands PPC well. A candidate can sound confident in an interview without being strong at campaign management.
The company then carries the risk of a poor hire. A PPC agency removes much of that recruitment burden. But you still need to choose the agency carefully. A polished website and a good sales call do not prove that the team managing your account is strong. Ask who will actually work on the campaigns and what experience they have with similar accounts.
Tools and Technology
PPC management can involve much more than opening Google Ads and changing bids. A team may use reporting systems, call tracking, feed tools, analytics software, CRM connections and research platforms. A PPC agency may already use several of these systems across its client accounts. An in-house team may need to buy, configure and manage them separately.
The software cost itself may not always be huge. The bigger issue is having someone who understands how the systems connect. For example, modern conversion measurement can involve website tags, first-party customer data and offline lead information. Google explains that enhanced conversions can use hashed first-party customer data to improve conversion measurement.
You can read the official details in Google Ads enhanced conversions guidance. Someone still needs to understand the setup, test it and make sure the data used for PPC decisions is reliable.
Business Knowledge: Where In-House Teams Can Be Stronger
An agency needs to learn your business. An internal employee lives inside it. That can be a major advantage. Suppose a chauffeur company receives many airport transfer leads but discovers that corporate accounts have much higher long-term value.
An internal PPC manager might hear this directly from the sales team. They can then adjust budgets, campaigns and landing pages around that information. Agencies can do the same thing, but only when the client shares useful sales data. If an agency receives no sales feedback, it may optimise towards form submissions rather than leads that actually make money.
That is why good PPC management needs communication whichever model you choose.
External Perspective: Where Agencies Can Be Stronger
Being close to a business has clear benefits. It can also create blind spots. A PPC agency normally works across multiple advertising accounts. That can expose its team to different campaign structures, landing-page problems, tracking setups and advertising challenges.
Patterns may become easier to spot because the team sees more than one PPC environment. An in-house employee has a different strength. They may understand your customers, products, margins, internal systems and sales process much more deeply. Neither type of knowledge is automatically better.
They solve different problems. A business with strong internal commercial knowledge but limited paid-media expertise may benefit from external specialist support. A company with a mature PPC team may value internal knowledge and direct control more heavily.
Which Model Gives Better Reporting?
Either can. Bad agencies produce bad reports. Bad internal teams can do the same. Strong reporting should answer business questions rather than fill pages with charts.
You should be able to see what was spent, what happened, what changed and what needs attention next. A report filled with impressions and clicks is not enough if your real target is qualified enquiries. The reporting model should connect PPC activity with calls, leads, sales, bookings and revenue.
Data Ownership Matters in Both Models
Your business should retain proper control over important advertising accounts and data. That includes your Google Ads account, analytics access and conversion information. If you work with an agency, agree how account access will work before the relationship begins. Google Ads allows businesses to grant different user access levels and later edit or remove that access.
You can check the official process in Google Ads account access guidance. You should not discover after ending an agency relationship that your company cannot easily access years of advertising history. The same principle applies to an in-house employee. Use company-controlled accounts and suitable administrator access rather than leaving everything tied to one person’s login.
Good account access and handover processes reduce that risk.
PPC Agency vs In-House for a Small London Business
A small London company often needs specialist PPC help but does not have enough work for a full-time paid media employee. Imagine a locksmith running Search campaigns across several London boroughs. The business may need campaign management, call tracking, landing-page advice and reporting. But it may not need a PPC Manager working on those tasks five days each week. In that case, a PPC agency may provide a better match between specialist support, cost and workload.
PPC Agency vs In-House for a Growing Business
Growing companies sit in the middle. Their PPC spend may be rising quickly. They may also be adding new services, locations or advertising channels. This is often where the decision becomes harder.
The company may need daily internal knowledge but also require more skills than one employee can offer. A hybrid approach can work well here. The internal marketing person owns the business knowledge and commercial plan. The PPC agency handles specialist campaign work, tracking and campaign scaling.
PPC Agency vs In-House for a Large Business
Larger companies may have enough paid media activity to justify a dedicated internal team. An in-house PPC Manager can work closely with product, sales, finance and leadership. The business may also have designers, developers and analysts available internally. At that point, bringing more work inside can become more practical.
However, large companies still use PPC agencies. They may bring agencies in for specialist channels, international campaigns, audits, tracking projects, temporary support or independent account reviews. So this does not always need to be an either-or decision.
The Hybrid PPC Model
A hybrid model combines internal ownership with external expertise. For many businesses, this can be a practical middle ground. An internal Marketing Manager might own targets, budgets and sales feedback. The PPC agency then manages campaigns and provides technical paid-media expertise.
Another company may have an internal PPC Manager but use an agency for paid social, Shopping feeds or large account audits. The split can change as the business grows. The key is to make ownership clear. Everyone should know who controls strategy, campaign changes, tracking, creative work and reporting.
When a PPC Agency May Make More Sense
An agency may be worth considering when you need several PPC skills but do not have enough work for a full internal team. It can also help when campaigns change with seasons, you use several channels, your tracking needs work or you want outside expertise before increasing spend. This is especially relevant when one internal hire would still need freelancers or outside specialists for other parts of the account. For businesses considering this route, Wixdek provides a dedicated PPC agency in London service covering campaign management, tracking, budget control and ongoing optimisation.
When In-House PPC May Make More Sense
In-house management becomes more attractive when your paid media workload is large and stable. It can also work well when campaigns depend heavily on fast internal communication. Your company should be ready to support the role properly. That means clear targets, reliable tracking, sales feedback and access to technical or creative help when needed.
Simply hiring a PPC Manager without those systems can leave them trying to fix business problems that sit outside advertising.
PPC Agency vs In-House: Questions to Ask Before Deciding
Before choosing either model, answer these questions:
- Is there enough PPC work for one person every week?
- How many advertising platforms do we use?
- Does the account need specialist tracking or technical work?
- Do we have reliable lead and sales data?
- Can someone internally manage and develop a PPC employee?
- How quickly do our campaigns need to change?
- Do we need design, development or feed support?
- What happens if our PPC manager leaves?
- Are we comparing an agency fee with salary only, or total employment cost?
- Which option gives us the skills we actually need?
Do not choose based only on the cheapest number. The cheapest model can become expensive if it creates wasted ad spend or poor decisions.
How Does PPC Compare With SEO?
PPC gives you paid visibility. SEO focuses on building organic search visibility. They work differently and have different cost patterns, timescales and strengths. Some businesses need one more than the other.
Many use both. If you are deciding how to split your search marketing budget, read our SEO vs PPC comparison.
Set the Budget Before Choosing the Management Model
It is difficult to choose between agency and in-house PPC management without knowing what you plan to spend. A £1,500 monthly advertising account is very different from a £100,000 account. Start with the commercial target. Work out how many leads or sales you need, what a customer is worth and what you can afford to spend acquiring one.
Then decide how much management the account justifies. Our set a Google Ads budget without guessing guide covers that decision in more detail.
How Wixdek Approaches PPC Management
At Wixdek, we look at PPC as a business-growth channel rather than a traffic contest. Clicks are useful only when they move towards real outcomes. That means looking at campaign structure, tracking, calls, forms, sales, landing pages, budget control and the cost of gaining a customer. We also do not think every business automatically needs an agency forever.
A company may start with external support and later build its own internal PPC capability. Another business may already have an internal marketing team but need specialist help with Google Ads, tracking or campaign scaling. The right setup depends on the account and the business behind it. If you want an outside view before making that decision, our PPC agency in London page explains how Wixdek approaches PPC management.

PPC Agency vs In-House Management: Final Decision
So, should you use a PPC agency or hire in-house? Start with workload, not preference. If your account needs several specialist skills but does not create enough work for a complete internal team, an agency can make sense. If PPC is a large and constant part of your business, and your internal marketing systems are already mature, hiring in-house can become more attractive.
If you sit somewhere between the two, consider a hybrid model. The main thing is to compare the complete picture. Look at total cost, capability, control, business knowledge, campaign complexity, team maturity and the risk of depending on one person. That gives you a much better answer than asking which option is simply cheaper.
If you are unsure which structure fits your current PPC account, Wixdek can review your campaigns, tracking and account complexity before you commit to a larger agency package or a full-time hire.
Frequently Asked Questions
Is a PPC agency cheaper than hiring in-house?
It can be, especially when a business does not have enough PPC work for a full-time employee. Compare the agency management fee with the full employment cost rather than salary alone.
How much does an in-house PPC Manager cost in London?
Indeed reports an average London PPC Manager base salary of about £41,663 per year. The real employer cost can be higher once National Insurance, pension costs, software, equipment, training and recruitment are included.
What are the main benefits of using a PPC agency?
An agency can provide access to several skills, easier scaling and more cover when one team member is away. It can also reduce the need to recruit several specialist roles internally.
What are the main benefits of in-house PPC management?
An internal PPC Manager can build deep knowledge of your company, products, sales process and customers. They also work solely on your business instead of dividing time across several clients.
What is the biggest drawback of a PPC agency?
An agency manages more than one client. It therefore may not have the same daily business knowledge as an internal employee. Good communication and regular sales feedback can reduce this gap.
What is the biggest risk of hiring one PPC Manager?
One employee can become a single point of failure. The business may lose campaign knowledge or capacity if that person is unavailable or leaves.
When should a company bring PPC in-house?
It becomes more practical when PPC creates a large and steady workload. The business should also have enough internal marketing maturity to support the employee properly.
Can I use an in-house PPC Manager and an agency together?
Yes. A hybrid approach can work well. Your internal employee can own company knowledge and strategy while an agency supports specialist channels, tracking, scaling or audits.
Should a small business hire a PPC Manager?
Not automatically. If the business only has a small advertising account, there may not be enough ongoing work to justify a full-time specialist.
How do I choose between a PPC agency and in-house management?
Compare total cost, account complexity, required skills, internal team maturity, control needs and workload. Use the two scorecards in this guide to compare the options more clearly.
