ROAS (Return on Ad Spend) is a vanity metric that can mask unprofitable customer acquisition. By focusing on POAS (Profit on Ad Spend), brands are forced to measure the actual profit generated from advertising, linking marketing directly to bottom-line health and avoiding the trap of 'growing broke'.

Lumping all search keywords together inflates performance, as branded search has a much lower effective CAC. People searching your brand name already know you from other channels. To accurately assess Google's performance and understand true customer acquisition, analyze the CAC for branded and non-branded keywords as distinct categories.

Don't combine branded and non-branded search when calculating channel CAC. Branded search converts users who already know you from other efforts, making its CAC artificially low. Separating them is crucial to accurately assess how well your ads are acquiring truly new customers.

Set clear expectations for paid ad performance. A successful PPC campaign should generate $3 to $5 in revenue for every $1 spent. Google Local Services Ads (LSAs) should yield an even higher return due to their lead guarantee model.

Instead of judging each marketing channel's Return on Ad Spend (ROAS) in isolation, contractors should measure overall ROAS. This approach accounts for the entire customer journey and exposes whether operational weaknesses, not just marketing, are hindering revenue generation from incoming leads.

With soaring non-branded CPCs and the rise of zero-click search, running branded campaigns is increasingly vital. As users get information from AI summaries or social media and then search a brand directly, these campaigns become a highly efficient, low-cost way to capture high-intent traffic.

Optimizing for cheap leads can attract low-quality subscribers who don't convert. MarketBeat found greater profitability by paying more per subscriber from reputable sources, which resulted in a much higher return on ad spend (ROAS).

Marketers fixate on efficiency metrics like ROAS. The real goal is maximizing profit. A lower, but still profitable, ROAS can allow for greater scale, more customers, and ultimately more money in your pocket at the end of the month.

Instead of optimizing each channel in isolation, establish a single blended CAC target across all marketing efforts. This provides a holistic view of performance, preventing premature cuts to channels that assist conversions attributed elsewhere. It acts as a single health metric for your entire acquisition strategy.
