Competitor Friction
How to switch your Google Ads agency
Switching agencies feels risky. But staying with the wrong agency is riskier. This guide shows you how to transition safely without losing momentum.
The fear of switching is almost always worse than the reality. A structured 6-week transition, with a parallel run period, protects your performance while giving the new agency time to understand your business properly.
Warning Signs
Signs it is time to switch
If you recognise three or more of these, your agency relationship has likely run its course.
Results Have Plateaued
Your ROAS has flatlined for 6+ months. Your agency says it is market conditions. You suspect it is capability. A good test: have they proposed a single structural change in the last quarter?
Communication Has Dried Up
Monthly calls replaced by quarterly. Reports are templates with no narrative. Questions go unanswered for days. When your agency goes quiet, it usually means they have nothing new to say - or they are avoiding a conversation about declining performance.
No Strategic Input
They optimise bids but never challenge your product mix, pricing, or commercial strategy. If your agency has never asked about your margins, they are not managing your advertising investment - they are managing your ad account. These are different things.
You Cannot See Your Data
They own the accounts. You do not have admin access. You do not know what is really happening. This is the single biggest red flag - and it is more common than it should be.
Self-Assessment
What your current agency should be providing
Score your current agency. Items marked as critical are non-negotiable - if your agency is not providing these, the relationship has a fundamental problem.

Full admin access to your Google Ads account

The Process
How do you switch Google Ads agency safely?
A structured 6-week transition that protects your performance and minimises disruption.
- Discovery call - 30-minute conversation about your situation and goals.
- Commercial audit - Review account structure and strategy before committing.
- Transition plan - Detailed handover covering access, data, and launch strategy.
- Parallel run - 2 weeks running alongside current agency for continuity.
- Full handover - Complete control with weekly reporting and proactive optimisation.
Discovery Call
Week 130-minute conversation to understand your current situation, frustrations, and goals. We will be honest about whether we are the right fit.
We ask about your margins, your products, your cash flow cycle - not just your ROAS target. If we do not think we can improve your commercial outcomes, we will tell you.
Commercial Audit
Week 2We review your account structure, bidding strategy, and commercial alignment before you commit.
This is not a sales document disguised as an audit. We will show you exactly what we'd change, why, and the projected impact. If the audit doesn't reveal opportunities, you pay nothing and keep the analysis.
Transition Plan
Week 3We create a detailed handover plan: account access, historical data, and launch strategy.
We document every campaign, every bid strategy, every custom label. Nothing gets lost in the transition. Your current performance is the baseline - we preserve it before we improve it.
Parallel Run
Week 4-5We run alongside your current agency for 2 weeks to ensure continuity before full handover.
During the parallel run, we shadow the account without making changes. We build our understanding, prepare our restructure plan, and ensure zero performance disruption on handover day.
Full Management
Week 6+We take full control with weekly reporting, strategy calls, and proactive optimisation.
From week 6, you receive weekly Loom walkthroughs, access to live dashboards, and a named strategist who understands your business. No templates, no generic updates.
Your Protection
How we protect you during transition
We structure every engagement to give you control and flexibility. You should never feel locked in.
You Own Everything
Your Google Ads accounts stay in your name. You have admin access from day one. Your data, your accounts, your assets - always.
Rolling Monthly After Setup
After an initial 3-month implementation period, you move to rolling monthly with 30 days notice. If we stop delivering value, you leave. Simple.
Transparent Reporting
Weekly Loom updates, monthly strategy calls, and full visibility into every change we make. You will always know what we did, why, and what happened as a result.
Commercial Alignment
Fixed-fee pricing means our incentives align with yours: profit, not spend inflation. We earn the same whether your budget is £20k or £80k.
When should you switch Google Ads agencies?
TLDR: Plateau for 6+ months, poor communication, no strategic input, or lack of account access.
Switch when ROAS has plateaued for 6+ months without structural changes, communication has dried up (monthly calls replaced by quarterly), there's no strategic input on product mix or pricing, or you don't have admin access to your own accounts. The last point - not owning your data - is the single biggest red flag.
How long does it take to switch Google Ads agencies without losing performance?
TLDR: 4-6 weeks for a clean transition. Expect a 10-15% dip that recovers within 30 days.
A well-managed agency transition takes 4-6 weeks: Week 1 for discovery, Week 2 for a commercial audit, Weeks 3-4 for transition planning and data handover, and Weeks 5-6 for the live switchover. Expect a brief learning phase dip of 10-15% that typically recovers within 30 days. The key is maintaining campaign history and not resetting bid strategies unnecessarily.
