Many businesses running paid ads in 2024–2026 are stuck in a frustrating loop. Their google ads performance has plateaued, leads have dried up, or ad spend keeps climbing without a clear return. Yet the idea of switching agencies feels risky. Will you lose your conversion data? Will campaigns go dark? Will you start spending from scratch?
The short answer is no, not if you do it right. This article will show you the concrete signs that it is time to change your google ads agency, how to protect every piece of data and tracking you have built, and a safe step-by-step plan to transition without tanking your results.
At Sun Media Marketing, we are a google ads and SEO-focused digital marketing agency based in Ahmedabad, India, working with international SMBs and enterprises across ecommerce, professional services, real estate, healthcare, education, and more. We have helped dozens of businesses navigate this exact transition, and the guidance here comes from that hands-on experience.
Whether you are moving from a freelancer to an agency, switching between agencies, or evaluating partners in the US, UK, Middle East, India, or Southeast Asia, the decision framework is the same. The focus is practical: how to tell if your current agency has hit its ceiling, when to move on, and how to protect your ad spend during the transition.
The hardest part of deciding to leave an ads agency is separating real problems from normal fluctuations. Here are the observable red flags that most agencies hope you will not notice.
Performance-based signs:
Communication red flags:
Strategic warning signs:
Operational signs:
Consider this scenario: a B2B software company has been spending steadily since 2022. Leads are flat. The agency keeps “waiting for the algorithm” instead of proposing concrete experiments with new offers, keyword research, or landing page tests. If your shopping campaigns outperform Search campaigns significantly but the agency never restructures around that insight, or you only run Search and Shopping campaigns without Dynamic Ads, stagnation occurs because the agency has become complacent with results.
Not every performance drop means you must switch. Sometimes market or product issues are to blame, and a good agency will fight through them.
When the agency is likely responsible:
When external factors are at play:
A simple diagnostic: if your agency is actively testing, reporting clearly, and aligning with your business metrics but the market has changed, it may be too early to switch. If they are passive, defensive, and reactive, the issue is likely the agency.
The best agencies focus on outcomes like lead quality and customer lifetime value, not just the cheapest click. They proactively ask about margins, average order value, and lead close rates. Understanding industry-specific metrics is important for effective campaign management.
A brief example: a healthcare clinic saw lead volume dip during 2025 regulatory changes, but the agency rescued performance by shifting budget to higher-intent keywords and updating ad messaging. That is how a good agency earns the right to keep your business.
The most critical factor before changing your google ads agency is ownership. Who actually controls your google ads account, your conversion tracking, and your billing?
Businesses should own their google ads accounts and have administrative access. This is non-negotiable.
Understand the difference: a standard google ads account should be owned by your business email. A manager account (MCC) is the tool agencies use to manage client accounts. Linking your account to an agency’s MCC does not transfer ownership, but some agencies blur this line.
The access you must have:
Common hostage scenarios:
The old agency created the ad account inside their own MCC years ago and never made the client an admin. They refuse to share login details or claim “the account belongs to us because we built it.” Transparency issues arise when agencies refuse to share revenue-generating keywords or account data that you paid for.
Our guidance: insist on admin access before announcing your departure. If the agency resists, reference Google’s own policies, which state that accounts and first-party data belong to the advertiser.
From Sun Media Marketing’s experience: a real estate client in 2023 nearly lost seven years of conversion history because the previous agency refused full access until the client escalated through Google support. This is avoidable if you secure ownership early.
Most real losses during an agency switch are not campaigns themselves but critical tracking and audience assets that took months or years to build.
Key assets to secure:
Conversion tracking is the number one thing that gets broken in rushed handovers. Install tracking before making major changes to campaigns. If the old agency owns the tag container or uses third-party call tracking without documentation, you are at risk.
Specific steps to take:
Performance tracking is essential for optimizing ad campaigns, and performance metrics should connect advertising data to business outcomes, not just platform-level numbers.
Negative keyword lists and audience lists are especially important for keeping ad spend efficient. Broad match keywords and Performance Max campaigns rely heavily on machine learning and historical signals. Losing those lists means the new agency starts partially blind.
We recommend that the new agency, whether Sun Media Marketing or another partner, performs a tracking and analytics audit before making structural changes. Agencies must ensure accurate and regularly audited conversion tracking so they know which conversions are trustworthy and which are inflated or duplicated.
This section focuses on hard numbers and patterns where switching is usually justified. A change in agency may be warranted if performance metrics stagnate or decline over a sustained period.
Hard metrics-based triggers:
Keyword strategy red flags:
Campaign management red flags:
Consider an ecommerce store where the agency kept a single “All Products” google shopping or PMax campaign for two years. Profitable SKUs were underfunded while poor SKUs absorbed too much ad spend. Proper tracking and campaign segmentation would have caught this early.
If you see stagnant or declining campaign performance alongside minimal change history and no strategic recommendations, it is a strong signal to change your google ads agency.
How an agency behaves can be as telling as the numbers in your google ads account. Performance declines can signal the need for a change, but so can patterns of avoidance and control.
Transparency issues:
Strategic disengagement:
Control tactics:
Imagine a manufacturing company where every suggestion for testing new markets or products is met with resistance. The agency cites “too much work” or blames Google’s automation instead of proposing solutions. Effective communication includes quick responses and regular reviews with clients. Business goals should align with agency strategies for effective campaign management. Frequency of missed communication can indicate the need for a new agency.
A healthy partnership should feel collaborative. Your agency should welcome informed questions, share dashboards, and agree on clear objectives. If not, it is time to plan a change.
Changing agencies always carries opportunity cost. Sometimes it is smarter to repair the relationship first.
Staying makes sense when your google ads agency has deep knowledge of your niche (legal, medical, real estate, industrial B2B), performance has dipped only recently, and they present a concrete recovery plan tied to specific experiments. Agencies can spot trends across multiple accounts quickly, and that institutional knowledge has real value.
Ask for a reset meeting. Request a 90-day roadmap that includes keyword research updates, ad copy testing, landing page ideas, and clear KPIs such as target CPA, ROAS, or qualified lead targets.
Set expectations in writing:
Communicate regularly with clients to build trust and transparency. If the agency is receptive, transparent about past mistakes, and proactive in changing their approach, it may be more efficient to continue instead of restarting with a new partner.
At Sun Media Marketing, we sometimes advise prospects to stay with their current agency when the underlying marketing strategy is sound and the issues are minor. That is how we build trust and emphasise long-term partnership over quick wins.
Once you have decided to change, compare agencies based on their approach, not just their pitch decks.
Evaluation criteria:
Tracking and data handling:
Team and expertise:
Sun Media Marketing typically shares a free analysis in the form of an initial audit outline and high-level strategy concepts without promising specific numbers. We explain where we will coordinate with SEO and content marketing teams to improve overall ROI.
Finally, check cultural fit: communication style, time zones, language, and whether the agency is comfortable working alongside your internal marketing or sales team.
Here is a concrete, step-by-step process that minimises risk and downtime when moving from one google ads agency to another.
Step 1 – Confirm Ownership. Verify you have admin access to the google ads account, GA4, Tag Manager, and billing. If not, secure it before announcing the switch. This is the single most important step. Check your payment profile and ensure billing is under your business, not the agency.
Step 2 – Export Historical Data. Download keyword, search term, ad, and conversion performance reports for the last 12 to 24 months. Export audience lists and negative keyword lists. Review existing campaigns to identify performance insights before anything changes.
Step 3 – Audit Tracking. Document which conversion events exist, what values are assigned, and which attribution models are in use. Capture screenshots and settings. Proper tracking documentation prevents the new agency from inheriting broken measurement.
Step 4 – Select and Brief the New Agency. Finalise your new partner. At Sun Media Marketing, we ask clients to share their goals, current challenges, and exported data before any structural changes are made. This briefing period typically takes several weeks but prevents costly mistakes.
Step 5 – Grant Access and Run in Parallel. Link the new agency’s manager account to your ad account. Keep the old agency connected for a short overlap (typically days, not months) while campaigns remain live and billing stays unchanged. Use existing high-performing ads to troubleshoot new campaigns during this window.
Step 6 – Implement Gradual Changes. Avoid making too many changes at once to maintain performance. The new agency should test a new campaign alongside old ones, not rewrite everything overnight. This protects learning phases and algorithmic stability.
Step 7 – Remove Old Agency Access. Once proper tracking is verified and new campaigns are stable, remove the old agency’s access from your google ads account and related tools. Agencies provide ongoing campaign optimization services, and your new partner should now have full ownership of that process.
A switch done right should not require “going dark” or pausing all paid ads.
Why parallel running works:
Keep existing high-performing campaigns live while the new agency builds improved structures. Gradually shift budget from old to new campaigns as data proves better performance. This is how many advertisers avoid the dreaded “transition tax,” where CPL can spike by 30 percent or more during poorly managed handovers.
Tactics for stability:
Realistic expectations:
Minor fluctuations for two to four weeks can be normal while Google’s algorithms relearn under new structures. But drastic, prolonged drops usually indicate aggressive or poorly sequenced changes.
From our experience at Sun Media Marketing: an ecommerce client transitioned by keeping legacy Search campaigns live while we introduced a segmented Performance Max and Shopping structure over three weeks. We only paused the old campaigns once the new ones consistently beat baseline ROAS, delivering maximum performance without unnecessary risk.
Hiring an agency saves time and resources for businesses, but only if the transition itself does not become a resource drain. A disciplined, phased approach prevents that.
A google ads agency switch is also a chance to fix deeper digital issues, not just change who pushes the buttons. Agencies should act as growth partners rather than just service providers, and this is the moment to set that expectation.
Landing pages and on-site experience:
Review page speed, mobile UX, clarity of calls to action, and alignment between ad copy and page content with the new agency. This has a significant impact in high-intent sectors like legal, medical, and B2B services, where a poor landing page experience kills conversions regardless of how good the ad campaign is.
Integrating Google Ads with SEO and content:
Use search term reports to inform blog topics, FAQ pages, and landing pages. Leverage content marketing and link building alongside paid search to improve your website’s visibility and reduce long-term dependence on paid traffic. Brand messaging should be consistent across channels.
Broader funnel tracking:
Connect Google Ads with CRM systems so you can measure success by seeing which keywords and campaigns generate leads that actually close into more revenue, not just form fills. This is where you move from tracking clicks to tracking business outcomes. The ability to drive revenue from paid search depends on seeing the full picture.
Cross-channel view:
A combined view of google ads, organic search, and social media allows better budget allocation and reveals where incremental ad spend is most profitable.
A brief example: an educational institution, after switching agencies, aligned Google Ads, SEO, and content marketing. The result was more qualified international student inquiries and better segmentation between on-campus and online course campaigns, all while keeping cost per lead under control.
Many business owners delay switching until they see proof that others have done it safely and profitably. Here are three anonymised examples that illustrate the pattern.
Example 1 – Ecommerce brand:
A mid-sized online retailer came from a previous agency with messy broad match usage and no negative keyword lists. Their google shopping and Search campaigns were running without segmentation, and the agency lacked a clear plan for campaign management. After a carefully planned switch, refined keyword research, and Shopping/PMax restructuring, the retailer saw a substantial improvement in return on ad spend and better control over where every dollar went. Shopping ads and paid search worked together instead of cannibalising each other. The transition took a few months, but the ROI improvement made it a no brainer.
Example 2 – Professional services firm:
A legal services client’s previous agency focused heavily on branded terms. More than half of all conversions came from people already searching the firm’s name, which was more revenue that SEO should have captured. After switching, the new agency placed more emphasis on non-branded google ads campaigns and local targeting. The result was higher-quality leads aligned with high-value services and less money wasted on traffic that would have arrived organically. Account managers worked directly with the firm’s intake team to track lead quality through close, connecting advertising data to actual case value and conversion value.
Example 3 – Healthcare client:
A medical practice discovered during a transition audit that its previous agency had duplicated conversion tracking, inflating lead counts by nearly 30 percent. After fixing proper tracking and aligning call tracking data with google ads, the practice had an accurate view of campaign performance for the first time. New campaigns scaled steadily while cost per lead stayed under control. Performance reports finally reflected reality instead of inflated numbers.
In all cases, the turning point was a structured handover, strong tracking, and collaborative strategy. There were no magic tricks or unrealistic guarantees. The agencies that deliver results long-term are the ones that invest in the initial setup, get measurement right, and build from there.
Switching google ads agencies is safe if you control your account, protect your data, and choose a partner focused on measurable outcomes.
Your pre-switch checklist:
The key question is not “Will I lose my Google Ads data?” It is “Do I have control over my google ads account and strategy?”

We combine expertise in PPC, SEO, and content with transparent reporting and ROI-driven campaigns across many accounts and industries.

A well-planned agency switch can be the moment your google ads account moves from maintenance mode to a structured growth path. The businesses that act on the signs, protect their data, and choose a collaborative partner are the ones that start spending smarter and generating more conversions. That is much value that compounds over time, and it is available to every business willing to take the step.
You should consider changing your Google Ads agency when performance consistently declines, CPA or CPL keeps increasing, qualified leads are falling, reporting lacks transparency, or your agency has stopped providing a clear testing and growth strategy.
Look for sustained increases in cost per conversion, declining conversion rates, stagnant revenue, wasted ad spend, poor search-term management, outdated campaign structures, and a lack of proactive optimization or strategic recommendations.
No. You should not lose your historical Google Ads data when changing agencies. Make sure your business has administrative access to the Google Ads account and export important campaign, keyword, search-term, audience, and conversion data before the transition.
Your business should own the Google Ads account and maintain administrative access using a company-controlled email address. Your agency can manage the account through its Google Ads manager account without owning the underlying advertiser account.
Before switching, secure admin access to Google Ads, GA4, Google Tag Manager, billing, conversion tracking, audience lists, negative keyword lists, campaign history, and other important advertising assets.
The transition can take several weeks depending on account complexity, tracking requirements, campaign structure, and the amount of historical data that needs to be reviewed. A short overlap between agencies can help reduce disruption.
Yes. In many cases, campaigns can remain active while the new agency audits the account and prepares its strategy. Gradual changes and parallel campaign testing can help minimize performance fluctuations.
Look for proven experience in your industry, transparent reporting, strong conversion tracking expertise, strategic keyword research, landing-page knowledge, experience with Performance Max and modern bidding strategies, and a clear plan tied to business outcomes.
Protect account ownership and tracking, export historical data, maintain proven campaigns, avoid making too many major changes simultaneously, set temporary budget and performance guardrails, and allow the new agency to make changes gradually.
Not necessarily. First determine whether the decline is caused by the agency, market conditions, seasonality, pricing, website problems, or other external factors. If the agency is transparent and has a concrete recovery plan, staying may be better than switching.
