Google’s rollout of Performance Max in 2022 presented challenges and opportunities to create a more refined full-funnel strategy for online retailer, Elverys.By using category segmentation and full-funnel awareness targeting to optimise Performance Max campaigns, we generated at 26% increase in revenue YoY, increased ROAS from 8.3 to 9.1 and ultimately helped Elverys to achieve their overall business revenue target for the year.
In early 2021, Google Ads announced that Performance Max would replace Smart Shopping - a historical cornerstone of Elverys' Google Ads strategy. Not just a new form of Shopping Ads, Performance Max campaigns would reach across Display, Youtube and Paid Search. While a powerful new format for advertising, PMax also proves a challenge to traditional strategies by concealing key performance data and removing control over audience targeting.
With Shopping Ads historically representing 14% of overall revenue for Elverys, and Google Ads accounting for 52% of overall online revenue - it was imperative that we re-visit not just our Shopping Ads but overall PPC strategy to incorporate the targeting power of Performance Max.
In order to retain eyes on key marketing insights and make sure we were driving the highest return possible, we created a two-part solution to fully optimize Performance Max and make sure that as much data and insights were being gathered and utilized to create a tight overall marketing funnel.

Performance Max Segmentation - Due to the size and variation of Elverys’ online catalog, a custom rule-based labelling system was set up to separate products into key categories prior to uploading onto the Merchant Centre. Additional custom rules within the Google Merchant Center further refined the list based on product title and category. These segmented PMax campaigns used highly specific audience signals from both Analytics audiences and first-party user data.
Full - Funnel Awareness Targeting
In doing so, a “loop” was created of PMax and other campaign activity refining one another’s results to continue to scale and drive stronger performance.
During Q4 2022, overall PPC activity achieved a 26% increase in revenue, for an increased ad spend of just 10%. ROAS improved 9.6% YoY (9.1 up from 8.3), playing a pivotal role in the business achieving its revenue targets for the year.
Upper Funnel - 45% of all new audience (prospecting) conversions during the Q4 period were driven by audiences generated from PMax insights, at a 73% higher ROAS than other prospecting campaigns.
Lower Funnel - Tag-based dynamic remarketing was the highest converting Display campaign of the Q4 period, achieving a ROAS of 8.35 - 182% stronger than the average ROAS of other Display campaigns, and 11% stronger than non-brand paid search.
