Why Use a Google Ads Agency to Manage Your Campaigns

by Curtis Chappell

Achieve Superior ROI with Google ADs and Purge Digital

Managing digital advertising on the Google Ads platform can be a very daunting task for any business. While Google Ads (formerly Google AdWords) offers an unparalleled opportunity to reach potential customers at the precise moment they are searching for products or services, managing these Pay-Per-Click (PPC) campaigns effectively is far from straightforward. 

The platform’s intricate features, constant updates, and competitive bidding environment demands a level of expertise and dedication that many businesses simply cannot afford to maintain in-house. This is where the strategic advantage of engaging a Google Ads agency, like Purge Digital,  becomes undeniably clear.

Hiring a specialised agency, like Purge Digital, to manage your PPC campaigns is not merely an outsourcing decision; it is an investment in professional knowledge, advanced technology, and ultimately, a superior Return on Investment (ROI). This article will explore the compelling reasons why businesses, particularly in Australia, should consider entrusting their Google Ads campaigns to a seasoned agency like Purge Digital, examining the breadth of our expertise, the tangible benefits we deliver, and what to expect from our services.

Unparalleled Expertise and Experience

One of the most significant advantages of partnering with Purge Digital is gaining access to a dedicated team of specialists whose core competency is paid search with over 30 years cumulative experience managing Google Ads.

  • Deep Platform Knowledge: Google Ads is a vast and ever-evolving platform. A professional agency’s team is immersed in its intricacies daily. We understand the nuances of various campaign types (Search, Display, Shopping, Video, Performance Max), bidding strategies, targeting options, landing page design and conversion tracking setups. This deep understanding allows us to leverage the platform’s full potential, often uncovering opportunities that an in-house team might miss.
  • Staying Ahead of Trends: The digital advertising landscape is in a constant state of flux, with Google regularly rolling out new features, policy changes, and algorithm updates almost daily. We make it our business to stay on the cutting edge of these developments, often gaining early access to beta features as a Google Partner. This proactive approach ensures your campaigns remain effective, compliant, and benefit from the latest innovations.
  • Industry-Specific Insights: Reputable agencies, like Purge Digital, work with a diverse portfolio of clients across various industries across Australia. This broad experience provides us with invaluable insights into different market dynamics, competitor strategies, and customer behaviours specific to particular sectors. We can apply learnings from similar businesses to your campaigns, accelerating success.
  • Complex Troubleshooting: Ad accounts can encounter technical glitches, policy violations, or performance plateaus. Our agency experts have a wealth of experience troubleshooting such issues efficiently, minimising downtime and optimising campaign health.
Factors Contributing to Google Ads Expertise

Strategic Time and Resource Efficiency

Managing effective Google Ads campaigns is a full-time job that demands significant time, effort, and specific skill sets.

  • Focus on Core Business: By outsourcing PPC management, business owners, and their internal teams, are freed from the time-consuming tasks of keyword research, ad copywriting, bid management, performance monitoring, negative keyword management and reporting. This allows them to reallocate valuable resources towards core business operations, product development, or customer service – areas where their expertise truly lies.
  • Reduced Overhead Costs: Hiring, training, and retaining an in-house PPC specialist can be a substantial financial burden. This includes salary, benefits, superannuation, training costs, and subscriptions to expensive analytics and research tools. Purge Digital provides access to a full team of experts and cutting-edge software at a fraction of the cost of building an equivalent internal department.
  • Scalability and Flexibility: We offer a highly scalable solution. Whether you need to rapidly increase ad spend for a seasonal promotion or scale back during leaner periods, we can adjust resources and strategies quickly without the logistical challenges associated with hiring or laying off in-house staff.

Optimised Performance and Superior ROI

The ultimate measure of a Google Ads campaign’s success is its ROI. The Ads Team at Purge Digital is fundamentally driven by achieving tangible results for our clients.

  • Data-Driven Decision Making: We leverage advanced analytics tools and custom dashboards to meticulously track campaign performance in real-time. We delve deep into metrics like Click-Through Rate (CTR), Cost-Per-Click (CPC), Conversion Rate, and Cost-Per-Acquisition (CPA). This data-driven approach allows us to identify trends, pinpoint inefficiencies, and make continuous, informed adjustments to maximise your ad spend.
  • Precision Targeting and Audience Insights: Purge Digital excels at identifying and segmenting your ideal customer base. We utilise sophisticated targeting options (demographics, interests, behaviours, remarketing lists) to ensure your ads reach the right people at the right time, reducing wasted ad spend on irrelevant clicks.
  • Continuous A/B Testing and Optimisation: PPC management is an iterative process of testing and refinement. We consistently conduct A/B tests on ad copy, headlines, calls-to-action, landing pages, and bidding strategies. This ongoing experimentation identifies what resonates best with your audience, leading to higher conversion rates and improved campaign efficiency.
  • Minimising Wasted Spend: Through rigorous negative keyword management, bid optimisation, and identifying underperforming elements, we actively work to reduce inefficient spending, ensuring your budget is allocated to the highest-converting opportunities.

Average Costs for Google Ads Agency Services in Australia

At Purge Digital, we provide a range of fees based on our clients needs for Google Ads management in Australia, the complexity of your campaigns, and your monthly ad spend.   

Common pricing models include:

  • Percentage of Ad Spend: Typically 10-15% of your monthly ad budget. This model aligns the agency’s fees with your spend, often benefiting larger advertisers. For example, a $10,000 monthly ad spend at 15% would incur a $1,500 management fee.
  • Fixed Monthly Retainer: A set fee charged regardless of ad spend. This can range from $1000 + GST per month for small accounts to $5,000+ per month + GST for complex enterprise-level or e-commerce campaigns.
  • Hybrid Models: A combination of a fixed fee plus a smaller percentage of ad spend.
  • Hourly Rates: Less common for ongoing management, typically ranging from $75 + GST to $250 per hour + GST, often used for specific audits or consultancy.

When selecting an agency, it’s crucial to understand the most appropriate pricing model for your business, which varies for everyone, and ensure it aligns with your budget and desired level of service. Purge Digital stands out from the crowd for a number of reasons.

FAQ Section

Q: How quickly will I see results from a Purge Digital Ads Campaign?

A: Google Ads can generate traffic and leads relatively quickly, often within days or a few weeks of campaign launch. However, significant improvements in ROI and optimal performance typically take 6-8 weeks as we gather data, refine targeting, and optimise bids and ad copy.

Q: Does Purge Digital control my budget?

A: No, you retain full control over your advertising budget. However, we know the required amount of daily spend to assure our clients actually get leads and conversions, so we suggest what the daily budget should be. The budget is spent within the Google Ads platform to achieve your goals. We advise on optimal budget levels but do not independently spend beyond your allocated amount.

Q: What should I look for when choosing a Google Ads agency in Australia?

A: Look for agencies that are Google Partners, like Purge Digital, or Premier Partners, have transparent pricing models, offer detailed reporting, provide case studies or testimonials relevant to your industry, and demonstrate a clear understanding of your business goals and target audience. Good communication is also key.

Q: Can I run Google Ads campaigns myself instead of hiring an agency?

A: Yes, you can. Google Ads is accessible to everyone. However, without the specialised knowledge, time commitment, and advanced tools that Purge Digital provides, you risk wasting significant budget on ineffective campaigns, missing out on crucial optimisation opportunities, conversion tracking and ultimately achieving a much lower ROI.

Q: What is the typical contract length with a Google Ads agency?

A: In the industry, contract lengths vary. However, Purge Digital does not require a contract.  We ask for a 2-weeks notice for pausing campaigns and a 4-week notice period to cancel a campaign. It’s important to discuss this clearly during the negotiation phase.

Managing Google Ads in-house might seem appealing for cost control, however the complexities and dynamic nature of the platform often make it a false economy. Engaging a dedicated Google Ads agency, like Purge Digital, particularly in a competitive market like Australia, provides an unparalleled blend of expertise, efficiency, and data-driven optimisation. This strategic partnership empowers businesses and e-commerce sites to not only navigate the intricacies of paid search but to truly maximise their online advertising spend, driving consistent leads, sales, and ultimately, sustainable business growth.
