When working with a Google Ads agency, it’s easy to focus on surface-level metrics like impressions and click-through rates. While these figures offer some value, they fail to address bigger concerns such as reaching the right people and generating profitable outcomes. This is where a performance-focused approach comes in.
Skilled ad experts believe clients deserve business results, not just ad engagement. This means reports go beyond surface-level data and focus on Key Performance Indicators (KPIs) that reflect a campaign’s effectiveness. Hence, here’s a breakdown of performance metrics that ad agencies should be showing you.
5 Google Ads Metrics That Matter
Understanding metrics provides clarity on ad spend effectiveness. It highlights which campaigns to scale, pause, and optimise to get the highest return. Although there are elements of a high-performing ad, it’s equally important to know what metrics to consider. That said, here are five metrics you should ask your Google Ads agency:
1. Conversion Rate by Campaign Type
This metric refers to the percentage of users who complete a desired action (e.g. purchase, sign-up) after clicking an ad by its campaign type. It tells you which campaign format (Search, Display, Remarketing, Shopping) generates real business outcomes.
Working with Google Ads specialists becomes more effective when you understand the different campaign types and how each supports your goals:
- Search campaigns bring high-intent users, but may be limited by competition or narrow keyword targeting.
- Display and Remarketing campaigns can drive users back to the site, nurturing cold traffic into conversions over time.
- Shopping campaigns can have higher conversion rates with proper feed management.
Knowing campaign types can help you choose the most effective and scalable ad formats for your product or service. It can also help you reallocate budget or pause underperforming campaigns.
2. Cost per Conversion (CPC) by Audience Segment
Cost per conversion (CPC) is a key metric that shows the average amount spent to generate one conversion. Since not all users cost the same to acquire, identifying the most profitable segments helps scale campaigns /efficiently. These insights can support more refined and effective targeting options for your campaigns. For this reason, Google Ads agency can exclude low-performing segments and reinvest in audiences that deliver higher returns.
3. Quality Score
Quality Score is a diagnostic metric assigned by Google that reflects the relevance and quality of a campaign’s keywords, ads, and landing pages. It influences the cost-per-click (CPC) and ad rank, even when multiple advertisers bid on the same keywords. In essence, a higher score is cost-effective in getting better ad placements, performance, and lower CPCs.
4. Impression Share
Some Google advertising agencies in Sydney tend to overlook this metric, even though it provides valuable insight into campaign visibility. Impression share shows the percentage of total available impressions ads received, compared to what they could have achieved. It highlights how much market share is lost. In most cases, loss of impression share occurs due to:
- Being outbid by competitors because of a limited budget, or
- Ads are being outranked because of low relevance, poor bidding, or low Quality Score.
This allows a Google Ads agency to balance budget allocation and campaign quality improvements for better visibility, higher click volume, and stronger overall performance in Google Ads auctions.
5. Return on Ad Spend (ROAS)
If you’re running conversion-based campaigns, the Return on Ad Spend (ROAS) is one of the most important metrics for performance marketing. According to Supliful, every dollar spent on advertising generates three dollars in revenue. This shows whether ads are not just driving traffic, but also how much they are converting efficiently into revenue.
That said, partnering with an experienced AdWords agency in Sydney will help you monitor your ad spend over time. It will also uncover performance trends, identify growth opportunities, and spot areas that may need optimisation.
Choose an Agency That Shares What Matters
If reports focus only on impressions, clicks, and CTRs, chances are the most valuable insights are being overlooked. These surface-level metrics don’t tell the full story of what drives revenue or business growth. However, not all hope is lost, as there are always opportunities to align reports with your business goals, provided the agency is willing to listen.
Fortunately, there are Sydney-based Google Ads agencies that prioritise ad performance, transparency, and return on investment.
