    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.

    0.9x

    Spend

    £28k/month

    Discovery + Audit (Week 1-2)

    Audit revealed: 34% of spend on products with <10% margin. No brand isolation. PMax cannibalising 58% of brand traffic. Custom labels unused. Feed missing 12 required attributes.

    Transition (Week 3-5)

    ROAS

    3.0x

    POAS

    0.9x

    Spend

    £28k/month

    Parallel run period. No changes to live campaigns. Built new campaign architecture, custom label taxonomy, and margin-banded bid targets in draft.

    Month 1 Under Management

    ROAS

    2.8x

    POAS

    1.2x

    Spend

    £24k/month

    Reduced spend by £4k/month by pausing loss-making non-brand campaigns. ROAS dropped (because we removed the brand subsidy), but POAS improved 33%.

    Month 3 Under Management

    ROAS

    3.4x

    POAS

    1.6x

    Spend

    £26k/month

    The Process

    How do you switch Google Ads agency safely?

    A structured 6-week transition that protects your performance and minimises disruption.

    1. Discovery call - 30-minute conversation about your situation and goals.
    2. Commercial audit - Review account structure and strategy before committing.
    3. Transition plan - Detailed handover covering access, data, and launch strategy.
    4. Parallel run - 2 weeks running alongside current agency for continuity.
    5. Full handover - Complete control with weekly reporting and proactive optimisation.
    01

    Discovery Call

    Week 1

    30-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.

    02

    Commercial Audit

    Week 2

    We 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.

    03

    Transition Plan

    Week 3

    We 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.

    04

    Parallel Run

    Week 4-5

    We 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.

    05

    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.

    Frequently Asked Questions

    Switching agencies safely

    A brief dip (1-2 weeks) is possible during the transition - primarily from bid strategy learning phases. However, a well-managed transition with a parallel run period minimises this. In our experience, 80% of transitions show no measurable performance dip, and the remaining 20% recover within 2 weeks. The bigger risk is staying with an underperforming agency - the slow bleed of plateaued performance costs far more than a brief transition dip.

    If you have admin access and the account is in your name, they cannot prevent the transfer. Simply remove their MCC access. If the account is in their name (a red flag), you may need Google's support to transfer ownership - or in worst cases, create a new account. This is why account ownership matters from day one, and why we never create client accounts under our MCC.

    You don't - until you see the audit. Our commercial audit is free and shows you exactly what we'd change, why, and the projected impact. If we can't identify material improvement opportunities, we'll tell you honestly. We'd rather lose a potential client than take one we can't help. Ask your current agency for the same level of specificity - the comparison usually speaks for itself.

    3 months for the initial implementation phase - this is the minimum time needed to properly audit, restructure, and stabilise a new approach. After that, you move to rolling monthly with 30 days notice. We earn your continued business every month. If we stop adding value, you should leave - and we make that easy.

    We don't recommend it. The ideal transition windows are January-February (post-peak recovery) or April-May (pre-summer). Switching during Q4 or during major promotional periods adds unnecessary risk. If your current situation is genuinely urgent, we can do a stabilisation-first approach - but we'll always be honest about the risks of transitioning during peak trading periods.

    At minimum: Google Ads admin access, Google Analytics access, Merchant Centre access, and any feed management tool credentials. Ideally, we also want: historical change logs, previous strategy documents, and any custom scripts or rules they've implemented. The more context we have, the smoother the transition. If your current agency is uncooperative, we can work with just the platform access - we've done it many times.
