Troubleshooting High Cost Per Conversion on Google Shopping Ads

Google Shopping Ads can be a great way to promote your products, but when you start seeing high costs per conversion, it can feel like you’re throwing your budget down the drain. In this blog post, we’ll dig deep into some common causes of high Cost Per Conversion (CPC) and provide you with practical solutions to help you optimize your Google Shopping campaigns for better performance.

Understanding Cost Per Conversion

Before we dive into troubleshooting tips, let’s clarify what Cost Per Conversion means. As defined by sources, it refers to the average amount you spend acquiring a conversion in your advertising efforts. This conversion could be anything from a sale to a lead, depending on the objectives of your campaign. Knowing how to calculate this metric is crucial for identifying areas that need improvement. The formula to calculate your CPC is:

[\text{Cost Per Conversion} = \frac{\text{Total Cost}}{\text{Total Conversions}}]

Common Causes of High Cost Per Conversion

There could be multiple reasons you’re experiencing a high CPC in your Google Shopping Ads. Here are some common issues:

Poor Product Feed Quality

A poorly optimized product feed can lead to high CPCs. This includes missing identifiers like GTINs and MPNs, as well as low-quality images and descriptions. If your product feed isn’t compliant with Google’s product data specification, it can cause disapprovals and can contribute to higher costs. Make sure your feed adheres to the guidelines outlined by Google.

Lack of Negative Keywords

Using negative keywords effectively can significantly reduce unwanted clicks and, in return, lower your CPC. Think about the search terms that might lead people to click your ad but aren’t likely to convert into sales. You don’t want to bid on irrelevant traffic that inflates your costs without providing any real benefits. You can find out how to manage your negative keywords here.

Ineffective Bidding Strategy

Your current bidding strategy can also affect CPCs. If you’re using one-size-fits-all bidding while your products differ vastly in margins, you’re potentially wasting budget on low-margin products. Explore different bidding strategies to ensure you are using a structure that aligns with your business goals.

Low Quality Score

Google uses a Quality Score system to determine the service deliverability and CPC. Factors contributing to a lower Quality Score usually include the relevance of your ads, poor click-through rates (CTR), and disapproved products. Keeping your Quality Score high is essential for lowering your CPC in the long run. Learn more about Quality Score from this resource.

High Competition in Your Industry

Depending on your industry, some products may just inherently have a higher CPC due to competition. If your competitors are larger or more recognized with higher ad budgets, your costs may be naturally higher. Analyzing your competitors and adjusting your bids accordingly might help mitigate some of this. Consider using the Auction Insights report for a breakdown of your competitors' performance in relation to your ads. You can access the insights via Google Ads.

Steps to Take for Troubleshooting

So, how do you address these issues? Here are some actionable steps you can follow:

1. Optimize Your Product Feeds

Use Quality Images: Ensure you have high-quality product images. Try to use at least 800x800 pixels.
Correct & Detailed Information: Make sure all product details like titles and descriptions are precise and catchy. Google pays attention to relevancy.
Complete Product Data: Include essential attributes, such as price, availability, and GTINs. Ensuring complete data is critical for visibility.
Data Validation: Validate your product feed using tools like Google Merchant Center to identify issues rapidly.

2. Use Negative Keywords Wisely

Regularly audit your keyword list and identify terms that may be draining your budget. Add them to your negative keywords list to avoid showing ads for irrelevant searches.
Use Google Ads’ search terms report to identify which keywords brought in unwanted clicks and conversions.

3. Test Different Bidding Strategies

Experiment with different automated bidding strategies such as Maximize Conversions or Target ROAS (Return on Ad Spend). This will allow Google to adjust bids for each individual ad auction based on how likely they are to convert.
Remember, do not just apply one bidding strategy across all products; tailor the strategy based on item performance and profitability.

4. Improve Your Quality Score

Monitor your ads’ performance closely and make adjustments based on what captures user interest. Your Quality Score directly influences your CPC, so higher relevance means paying less!
Regular A/B testing will also give valuable insights into what works and what doesn’t.

5. Research Competitors

Use tools to keep an eye on your competitors' ad spend and their strategy. Understanding their bids can offer insights into how you can position your products competitively.
Consider the potential of collaborating with other brands for cross-promotion to build brand recognition, increasing CTR.
