When Should You Work with a Google Ads Agency: Complete Guide

Managing marketing campaigns can become overwhelming as the business grows, and the moment you decide to partner with a Google Ads agency can make the difference between stagnation and accelerated profitability. Many entrepreneurs start by setting up their own campaigns. It's a natural learning process and a way to save budget in the early stages. However, the Google Ads platform is becoming increasingly complex, and algorithms are changing at a rapid pace.

At Sell More, we fully understand this dynamic. With former Google employees on our team, we have seen thousands of accounts and know exactly where the line is drawn between "I can do it myself" and "I need professional help." The purpose of this article is to provide you with clarity. We will not try to sell you services you do not need; rather, we will present the technical and economic reality of managing PPC campaigns at a high performance level.

Clear signs that you need a Google Ads agency to scale

The first indicator that you need to seek external help is a lack of time. An effective campaign requires more than just the initial setup. Monitoring, optimizing search terms, adjusting bids, and testing creatives take hours of work each week. If you notice that you check your Google Ads account only once a week or less, you are most likely losing money. A Google Ads agency has the resources to monitor your account daily, ensuring that your budget is not wasted on irrelevant clicks.

Another obvious sign is stagnation in results. You may have had success at the beginning, but now your cost per acquisition (CPA) has increased, while sales volume has remained constant. This is a common problem referred to as the "optimization plateau." To overcome this barrier, you need paid promotion experts who can implement advanced strategies, such as audience segmentation by customer lists or using automated scripts to adjust budgets.

The following situations indicate the need for outsourcing:

• You are spending a considerable budget (over 2000 EUR per month) without clarity on return on ad spend (ROAS).

• You are struggling to keep up with new types of campaigns like Performance Max or Demand Gen.

• Your site has traffic, but the conversion rate is much below the industry average.

• You feel that you are losing market share to competitors who are much more visible on the same keywords.

Why campaigns stagnate without a dedicated Google Ads agency

Stagnation does not occur out of malice, but from limited technical knowledge. Google Ads is a living ecosystem, based on real-time bidding and quality scores. An entrepreneur or a general marketing employee cannot know all the intricacies of the algorithm. This is where a Google Ads agency comes in, bringing a higher level of technical depth.

For example, the Quality Score directly influences how much you pay for a click. If you do not know how to perfectly align keywords with ads and the landing page, you will pay more than your competitors for the same position. An online advertising company will audit these elements and structure campaigns to maximize the quality score, reducing costs and increasing visibility.

Moreover, stagnation often results from a poor account structure. Many in-house managed accounts have a single campaign with hundreds of mixed keywords. This approach dilutes the budget. Our role as an agency is to segment services or products into granular ad groups (tight thematic structures), to provide users with exactly what they are looking for.

Cost analysis: In-house vs a Google Ads agency

A common fear among entrepreneurs is the additional cost of an agency. However, the math is simple and often favors outsourcing. Let's analyze the options. If you decide to hire an in-house specialist, you will need to pay a competitive salary, taxes to the state, equipment, ongoing training, and licenses for analysis software. Moreover, one person has a limited perspective.

In contrast, the fee for a Google Ads agency is typically a fraction of the cost of a full-time senior employee. But the major advantage is not just the savings on salaries, but the efficiency of the media budget. Think of it this way: if an agency optimizes your campaigns and reduces waste by 20%, that saving often fully covers the agency's cost. Moreover, access to an entire team of PPC specialists means you benefit from the cumulative experience of dozens of other accounts and industries, not just the experience of one person.

Partnering with us at Sell More means that you are not just paying for hours of work, but for performance. Your marketing budget becomes an investment, not an expense, and transparent reporting allows you to see exactly where every penny is going and what it brings back.

The complexity of the platform demands an experienced Google Ads agency

Google releases hundreds of updates each year. The interface changes, new metrics appear, and old strategies become outdated. For someone who does not live in the platform day-to-day, it is impossible to keep up. A Google Ads agency has the professional obligation to stay informed about every change. With a Google partner agency, you gain access to beta information and direct support, things that are hard to access for an ordinary user or an in-house employee.

A recent example is the transition to automation and artificial intelligence. Performance Max campaigns use machine learning to place ads across all of Google’s inventory (Shopping, YouTube, Search, Display, Discover, Maps). Although they seem easy to set up, they can consume huge budgets without results if not guided properly with audience signals, quality creative assets, and brand exclusions. A certified Google partner knows how to "navigate" these algorithms to work in favor of your business, leaving no room for inefficiencies.

Furthermore, the tracking and data analysis part has become extremely technical. Implementing Google Analytics 4 (GA4), setting up enhanced conversions and consent mode are essential to comply with legislation and to have accurate and complete data. A Google Ads agency has technical departments dedicated exclusively to these implementations, ensuring that the data you make decisions with is in line with reality.

Practical Scenario: How a Google Ads agency optimizes

To understand the real impact, let's take a hypothetical example based on the structures we often encounter at Sell More. Imagine a premium furniture online store. The owner manages the campaigns and has a ROAS (Return on Ad Spend) of 3. This means that for every 100 lei invested, they receive 300 lei. The profit is small after deducting product costs.

The owner contacts a Google Ads agency. In the first month, the agency does not increase the budget but restructures the account.

1. Search term analysis: The agency notices that a large part of the budget is going to generic terms like "cheap furniture" or "second-hand furniture," even though the store sells premium products. Massive lists of negative keywords are added.

2. Segmentation: Separate campaigns are created for "Luxury Sofas" and "Solid Wood Tables," with specific ads that mention quality and starting price, filtering out customers who cannot afford the products.

3. Shopping optimization: The product feed is optimized (titles, descriptions) to appear in relevant searches.

The result after 3 months? With the same invested budget, the ROAS increases to 5. This professional management of Google Ads campaigns has transformed a barely profitable sales channel into a main growth engine for the business. Although we cannot discuss specific data of former clients from our time at Google for confidentiality reasons, the principles of optimization remain the same and are rigorously applied in our agency.

What to look for in a top-performing Google Ads agency

Not all agencies are the same. The market is full of promises, but the deliverables vary. When you are ready to take the step, you need a clear list of criteria. A serious Google Ads agency will emphasize total transparency. You should have 24/7 access to your Google Ads account. If an agency tells you that "you cannot see the account because it is their property," run. The account and data are yours.

Look for a digital marketing team that asks questions about your business, not just about the budget. They need to understand your profit margin, the lifetime value of a customer (LTV), and the sales cycle. An agency that promises "guaranteed position 1 on Google" is usually a warning sign. No one can guarantee position 1 consistently because bidding is dynamic. The correct promise is increasing relevant traffic and conversions.

Also, reporting is vital. Don't settle for automated reports sent by a robot. You need data interpretation. A top Google Ads agency will explain to you monthly what worked, what didn’t, and what the plan is for the next month. Proactive communication is key to a long-term partnership.

Frequently Asked Questions about working with an agency

What is the minimum budget to work with an agency?

Most agencies have a minimum budget threshold, often starting from 500-1000 EUR per month. If your budget is very small (for example 100 EUR), the cost of agency services might exceed the media budget, which is not cost-effective. However, some freelance Google Ads professionals might offer one-time account setup services for smaller budgets.

How long will it take to see results?

Google Ads provides faster results than SEO, but optimization takes time. Typically, the first efficiency improvements are seen in the first month, but the maturity of campaigns and maximizing ROI is achieved after 3 months of data collection and continuous adjustments.

Does the agency also handle banner design?

It depends on the agency. At Sell More, we believe in an integrated approach. Since the performance of Display or Social Ads campaigns critically depends on visuals, we also provide support for creative production or guide your internal team to create converting materials.

Are you ready to scale with a profit-oriented Google Ads agency?

The decision to outsource marketing is a big but necessary step for any business looking to move beyond startup status or local small business. If you find yourself in the challenges described above (lack of time, stagnant results, or technical difficulties), it is clear that you need a partner. A Google Ads agency like Sell More does not just take a task off your shoulders but brings a strategic vision formed over years of experience, including inside the Google giant.

We do not believe in magic recipes but in data-driven work, continuous testing, and a deep understanding of buyer psychology. Do not let the complexity of the platform hinder your growth. The right expertise can unlock immense potential for your business.
