Case Study: PMax + lead forms reduced CPA by 38%

The problem of rising customer acquisition costs affects almost every business in paid traffic. Therefore, the key is not just to run ads on Google Ads, but to reduce unnecessary steps to conversion. Our experience shows that combining Performance Max with properly built lead generation through embedded forms significantly changes the economics of campaigns. In this article, we analyze the process, tools, and quality control that allow you to steadily reduce CPA based on proven industry data.

🚀 How PMax with lead forms reduces friction in the funnel

The essence of the approach

Performance Max collects signals from all Google inventory. When we add a lead form, the potential customer leaves the contact without going to the website. Fewer steps. Fewer losses. This is especially valuable where the audience interacts with ads on mobile devices and the time to make a decision is limited.

Performance Max campaigns with lead forms can generate up to 30% more qualified leads as users convert directly within the ad unit.

According to Google Ads Help (2024)

For businesses, this means that contextual advertising works not only for reach, but also for getting leads quickly. According to industry case studies in the CEE region, advertisers have recorded a CPA reduction of up to 38% after integrating lead forms into PMax (WordStream, 2024). We use this benchmark as a reference for planning expectations and requirements for traffic quality.

What WonderWeb does exactly

We combine campaign setup with the technical part of collecting applications. This is critical for stable lead generation and predictable cost per acquisition.

Next, we integrate forms with CRM so that each application automatically gets to the right stage of the sales funnel. This minimizes losses at the processing stage, speeds up the first contact, and increases the percentage of closing deals.

🧭 Implementation process: from hypothesis to stable CPA

Preparation of creatives and signals

For PMax, it is important to collect a high-quality Asset Group: adaptive headlines, descriptions, images, short videos. We test several variants of forms and questions. If sales last longer than one cycle, we add clarifying fields to the form to improve lead qualification without unnecessary burden on the user.

Creating and integrating lead forms

The form should be short and logical. Fields: name, phone or email, one clarifying question. For CRM integration, we use official connectors or webhooks. This is in line with our approach to technical implementation: website development with marketing requirements and smooth data transfer to the sales department.

If your product requires a landing page for high conversion with an additional explanation of the offer, we develop a separate Landing Page. Its task is to boost Google Ads ads when users do go to the site.

PMax training and optimization

We set aside a sufficient budget for the training period, monitor the “Lead Quality” signal through CRM, and make changes. In particular, we cut off non-targeted requests and review form options. This cycle allows us to bring CPA to the target values and keep it stable.

📊 Results and lead quality control

What does “minus 38% CPA” mean in practice

According to WordStream (2024), advertisers in CEE “reported up to 38% CPA reduction after integrating lead forms into PMax”. We use this figure as a benchmark for planning. The actual result depends on the niche, the quality of the offer, and the processing speed. Therefore, in our reports, we simultaneously track the cost of a qualified lead and the percentage of scheduled calls.

Metrics we track on a daily basis

In addition to CPA, we focus on Lead-to-MQL, the speed of the first contact, and the share of repeat calls. If we see an increase in cheap but low-quality applications, we level up the wording of the offer, clarify the questions in the form, and reallocate budgets between asset groups.

Technical discipline is important here. We “Create lead forms for collecting contact information within Google Ads campaigns and ensure their integration with CRM” (WonderWeb, 2024). This ensures that each application is transparently matched to the ad and creative.

🛠️ Practical tips from WonderWeb’s experience
