2. Review ROAS Metrics

2.1 ROAS by Listing Group

Beyond assets, listings play a significant role in campaign success. By scrutinising the ROAS by listing groups, you can identify and leverage the most effective listings for your campaign.

2.2 ROAS by Products

To truly optimise product-related campaigns, sort products by top-selling (revenue) metrics. This sheds light on the high-performing products that drive most of your returns.

3. Locations

3.1 Location Targeting Setting

Use geotargeting settings to maximise reach in the most responsive regions.

 Performance can vary by state, depending on the product or service provided. 

3.2 Bidding Strategy

A routine double-check of the bidding strategy ensures alignment with current performance. If metrics seem off, recalibration might be necessary.

3.3 URL Expansion

Sometimes simplicity wins. Consider turning off URL expansion to lead users directly to primary, high-converting landing pages without distractions.

4. Insights and Content Assessment

4.1 Insights Tab

The Insights tab in Google Ads offers valuable data. Regularly tap into this to refine your campaigns based on the latest patterns and trends.

5. Merchant Centre Check In

Regular Checks

A routine review of the Merchant Centre ensures there aren’t any product feed issues or policy violations that might hamper your campaign’s effectiveness.

From delving into ROAS metrics to ensuring adherence to policies in the Merchant Centre, each step contributes to a campaign’s overall success. By adopting these guidelines, Australian businesses can effectively leverage Google Ads to bolster their online presence and profitability.
