Should I switch PPC agencies?

If you are asking yourself whether you should switch PPC agency, there is usually a reason. Maybe performance has declined. Maybe lead quality has deteriorated. Maybe communication has become vague. Maybe reports arrive every month but you still do not really know what the agency is doing.

Or perhaps nothing is obviously wrong. You have simply started wondering whether your account could be performing better.

That does not automatically mean your current agency is bad. It does mean the relationship deserves a proper review.

The mistake is either staying indefinitely because changing feels risky, or firing an agency because you have had one disappointing month.

The better approach is to work out what the actual problem is first.

Do not switch agencies because you are frustrated. Switch when you understand why you are frustrated.

Should you switch PPC agencies?

Possibly. But first separate two questions:

• Is PPC underperforming?
• Is your PPC agency underperforming?

They are not the same thing. Advertising performance can decline because:

• Competition has increased
• Search demand has fallen
• Your market is seasonal
• Your prices have changed
• Your website conversion rate has dropped
• Competitors have improved their offers
• Your sales team is converting fewer leads
• Your product or service has become harder to sell

Changing agency will not magically fix those problems. But your agency should be able to identify them, explain them and recommend what to do next.

That distinction matters.

Start with the reason you are unhappy

Before looking for another agency, ask yourself one simple question.

What exactly do I want to be different?

Performance is not good enough is a start, but it is too broad. Try to be more specific. Perhaps:

• Cost per lead has increased significantly
• Revenue from PPC has fallen
• Lead quality is poor
• Nobody is testing anything new
• You rarely hear from the agency
• Reporting is difficult to understand
• Recommendations feel generic
• Tracking is unreliable
• The agency does not understand your sales process
• You keep speaking to different account managers
• Nobody seems accountable
• You no longer trust the numbers

Once you understand the problem, it becomes much easier to judge whether your current agency can fix it. It also makes choosing the next agency considerably easier.

Poor performance is not always the agency's fault

This is worth saying because prospective agencies have an obvious incentive to tell you otherwise.

Sometimes your current agency is doing a perfectly reasonable job in difficult circumstances.

If search demand falls 30%, an agency cannot manufacture another 30% of people looking for your service.

If your competitors start offering something significantly better, bidding harder is unlikely to solve the underlying problem.

If your landing page converts at 2% when competitors convert at 8%, the biggest opportunity may not be inside Google Ads.

And if your sales team only answers half the leads being generated, cheaper leads may not solve much either.

A good agency should still identify these issues. That is part of the job. But judge agencies on the things they can influence, rather than expecting them to control the entire market.

Signs it may be time to switch PPC agencies

There is rarely one single metric that tells you it is time to leave. It is normally a pattern. I would become concerned if several of these things were happening simultaneously.

Performance keeps declining without a credible explanation

Every PPC account has good months and bad months. The problem is not necessarily that performance has declined. The problem is when your agency cannot explain why.

If CPL increased from £60 to £95, someone should be investigating what changed. Was it:

• CPC?
• Conversion rate?
• Search demand?
• Search terms?
• Competition?
• Budget?
• Lead quality?
• Landing page performance?
• Tracking?
• A bidding change?
• Seasonality?

We are monitoring it is not much of an answer. You should expect diagnosis.

You only hear from them when you chase

Communication does not need to mean constant meetings. It does mean your agency should tell you when something important changes.

You should not be the person discovering:

• Spend suddenly increased
• Conversion tracking broke
• CPL doubled
• A campaign stopped spending
• Lead quality deteriorated
• Google introduced a change affecting the account

Your agency is being paid to manage the advertising. You should not need to manage your agency.

Reporting tells you what happened but not why

A report saying this is not analysis:

Spend: £12,400
Leads: 163
CPL: £76

Those numbers are useful, but they are only the starting point. You should also understand:

• Why performance changed
• What the agency learned
• What was changed
• What is being tested
• Where money is being wasted
• Where the next opportunity is
• What the agency recommends doing next

You should finish reading a PPC report knowing more than you did before opening it.

Nothing seems to change

This is a surprisingly common problem with mature agency relationships.

The first few months contain audits, restructures, new campaigns and testing. Then everything settles down. Six months later the account is effectively being maintained.

Maintenance matters. But PPC management should also involve progression. That could mean testing:

• New keywords
• New audiences
• New campaign types
• Different offers
• Landing pages
• Ad messaging
• Conversion values
• Bidding strategies
• Budget allocation
• Offline conversion data

Not everything needs changing constantly. But there should be evidence that somebody is still looking for the next improvement.

Your agency should be able to explain performance

One of the easiest tests is simply asking questions. Try:

• Why did performance change last month?
• Where do you think our biggest opportunity is?
• What is currently limiting growth?
• What are you testing next?
• Where are we wasting money?

You do not need the answers immediately. Some questions require investigation. What matters is whether you eventually receive a thoughtful, evidence-based answer.

A good PPC manager should understand the account deeply enough to have an opinion. If every answer sounds like we are continuing to optimise the campaigns, you may have a problem.

Look beyond cost per lead

This matters particularly for lead generation. Imagine two agencies produce these results.

On cost per lead, Agency A looks better. Once you include what happened after the lead arrived, the answer changes completely.

PPC should ultimately contribute to commercial outcomes. Depending on your business, that may mean looking at:

• Qualified leads
• Contact rates
• Appointments
• Opportunities
• Sales
• Revenue
• Customer acquisition cost
• Return on ad spend
• Lifetime value

An agency obsessed with reducing CPL without understanding what happens after the lead arrives can optimise your campaigns in completely the wrong direction.

Cheap leads are not necessarily good leads.

Has the account stopped progressing?

Open your Google Ads change history and look at the last few months.

You do not need hundreds of changes every week. Excessive tinkering can be just as damaging as neglect. But there should be evidence of active management.

Then ask your agency what they have learned recently. Not what they changed. What they learned. There is a difference.

We changed these keywords is activity.

We discovered that these search themes generate 40% more qualified opportunities, so we are shifting budget towards them is strategy.

You are paying for the second one.

Are you getting enough senior attention?

This is another common reason businesses reconsider their agency.

The senior person impresses you during the pitch. Then the contract is signed. Two weeks later your account is being managed by somebody you have never met.

Junior PPC managers are not inherently bad. Everyone starts somewhere. The problem is when your account is being managed without enough experience, supervision or strategic involvement.

You should know:

• Who manages your account
• Who makes strategic decisions
• Who reviews their work
• Who you speak to when something goes wrong

If you are paying senior-agency fees, expecting senior-level thinking is reasonable. It is worth understanding what PPC agencies charge for before deciding whether the fee and the attention actually match.

Is your tracking actually reliable?

Before deciding that PPC performance is poor, make sure you can trust the data.

We regularly audit accounts where Google is optimising towards things that are not genuine business outcomes. That can include:

• Contact page views
• Form starts
• Button clicks
• Email clicks
• Duplicate conversions
• Calls lasting a few seconds
• Imported events nobody remembers creating

At the same time, genuine leads or sales may not be tracked properly.

This affects more than reporting. Automated bidding uses conversion data to make decisions. If the data is bad, the algorithm can become extremely efficient at generating the wrong outcome. The same applies inside Meta Ads, where pixel and Conversion API events feed the same kind of automation.

Your agency should be able to tell you exactly what counts as a conversion and why. Google's documentation on primary and secondary conversion actions explains which ones feed bidding and which are observation only.

If nobody is certain, fix that before judging performance.

Does your PPC agency understand your business?

Knowing Google Ads is not enough. Your agency should understand:

• What makes you money
• Which services are most profitable
• Which customers you actually want
• What constitutes a good lead
• Your sales process
• Your margins
• Your capacity
• Your geographic priorities
• Your competitive advantages

Without that context, PPC becomes a media-buying exercise.

Suppose Service A generates leads for £40 and Service B generates leads for £70. Google Ads would suggest spending more on Service A. But perhaps Service B generates three times as much gross profit.

Commercial context changes the decision. Your agency needs enough understanding of the business to recognise that.

When you probably should not switch PPC agencies

There are also situations where changing agency may be premature.

You have had one bad month

Performance fluctuates. One disappointing month does not necessarily tell you much. Look at the trend.

You recently made major changes

New landing pages, bidding strategies, tracking, budgets or campaign structures can create short-term volatility. Give changes enough time to produce useful data.

Your expectations are unrealistic

No agency can guarantee permanent growth while simultaneously reducing acquisition costs indefinitely. Markets have limits.

The real problem sits elsewhere

If advertising generates strong-quality opportunities but your sales conversion rate has collapsed, PPC may not be the main problem.

Your agency has identified the issue and has a credible plan

Sometimes things go wrong. What matters is how the agency responds. If they understand the problem, communicate openly and have a sensible strategy for fixing it, replacing them may simply introduce more disruption.

Questions to ask your current agency before leaving

Before making a final decision, have a direct conversation. Ask them:

You may be surprised by the conversation. Perhaps there is far more happening behind the scenes than you realised. Or perhaps it confirms exactly what you suspected. Either outcome is useful.

Should you get another agency to audit the account?

If you are genuinely unsure, yes. An independent PPC audit can give you another perspective before you make a decision.

But there is an obvious caveat. The agency auditing your account probably wants your business. Treat dramatic claims accordingly.

Be cautious when somebody spends 30 minutes inside your account and concludes that your existing agency has done everything wrong.

Most established accounts contain a mixture of:

• Good decisions
• Bad decisions
• Old experiments
• Historical compromises
• Legacy structures
• Things that made sense at the time
• Things that genuinely need fixing

A useful audit should explain what matters commercially, not simply generate the longest possible list of things another agency could criticise.

Finding mistakes is easy. Understanding which mistakes are costing the business money is much more useful.

What should you expect from a new PPC agency?

Do not simply replace one agency with another because the second pitch sounds better. Ask what will actually be different.

A strong prospective agency should want to understand your:

• Current performance
• Historical performance
• Conversion tracking
• Lead quality
• Sales data
• Website
• Commercial objectives
• Existing campaign structure

They should also be comfortable telling you when something is already working. If every campaign needs rebuilding before they have properly analysed it, I would question why.

Likewise, be sceptical of promises such as we will halve your CPL. Maybe they will. But nobody can responsibly guarantee that without understanding the account, market and business in considerable detail. That is equally true whether you appoint an agency or a PPC consultant.

Look for evidence of thought rather than certainty.

The risk of switching PPC agencies

Changing agency does carry some risk. The biggest problems normally come from poor handovers rather than the act of switching itself.

You want to protect:

• Advertising account ownership
• Historical campaign data
• Conversion tracking
• Analytics
• Call tracking
• CRM integrations
• Billing
• Automated bidding data
• Active experiments

Ownership is the one to check first. Google's account access levels exist so an agency can work inside an account your business continues to own.

The new agency should understand the account before making unnecessary structural changes.

If you have already decided to move, read our guide on switching PPC agencies without dropping the ball on performance before starting the handover.

A well-managed transition should not require your advertising to grind to a halt.

How to decide whether to switch PPC agencies

I would look at five areas.

1. Performance

Is the account generating commercially acceptable results?

2. Explanation

Does your agency understand why performance is where it is?

3. Strategy

Is there a credible plan for improving it?

4. Communication

Do you know what is happening without constantly asking?

5. Trust

Do you still believe the people managing the account are capable of making good decisions with your money?

That last one matters more than people sometimes realise. PPC agencies control significant advertising budgets. You do not need to agree with every decision they make. But you need confidence that decisions are being made thoughtfully.

If performance is struggling but you still have confidence in the strategy, there may be no reason to leave.

If performance is strong but you have completely lost trust in the agency, the relationship may still be difficult to sustain.

If performance is poor, strategy is unclear and trust has disappeared, the decision becomes much easier.

Conclusion

So, should you switch PPC agencies? Do not base the decision on one bad month or one attractive sales pitch from another agency. Look at the bigger picture.

Is performance commercially viable? Can your agency explain what is happening? Are they proactively improving the account? Do they understand your business? Can you trust the data? Do you still trust them?

If the answers are mostly yes, fixing the relationship may make more sense than replacing it.

If the answers are consistently no, staying because switching feels inconvenient is not much of a strategy either.

Your advertising budget is too important to leave on autopilot.

Stay because the agency is still the right choice. Not because changing agencies feels like too much hassle.

Not sure whether you should switch PPC agencies?

We can independently audit your existing PPC accounts, tracking and performance before you make a decision. If your current agency is doing a good job, we will tell you. If we find meaningful opportunities they are missing, we will show you where they are and what we would do differently. Either way, you will have considerably more information before deciding whether to stay or move.
