Google Expands Brand Lift Studies With an Enhanced Option

Google has launched an Enhanced version of Brand Lift Studies — the surveys that show how much an ad campaign raised brand awareness. The announcement came on July 20, 2026, and advertisers now choose between standard and more sensitive measurement.

The mechanics are unchanged: Google surveys two groups — people exposed to the ad and a control group — and the gap in their answers is the "lift" in brand metrics such as recall or purchase intent. Enhanced simply makes that measurement statistically more sensitive.

The key difference is sensitivity. Standard studies detect a lift of 2% or higher, while the Enhanced version can "see" even a weak effect — from 1.2%. The price for that precision is budget:

• standard — detects lift from 2%, base budget;
• Enhanced — catches lift from 1.2%, needs roughly 3x the budget;
• the chance of detecting a positive effect rises by about 60%;
• the option was first spotted by Google Ads specialist Thomas Eccel.

According to Search Engine Land, this is part of Google's broader bet on brand-campaign measurement — advertisers increasingly want proof that upper-funnel spend drives real outcomes, not "just impressions."

What it means for advertisers. Enhanced is not for everyone. If your brand lift is already visible, there is no need to pay triple — standard is enough. But for niche brands and campaigns with a modest effect that a standard study simply cannot see, the higher sensitivity may finally show that the awareness budget is working. The key is to do the math: does a 60% better chance of detecting lift justify triple the cost in your specific case.
