The article is the full, canonical source. **Direct answer:** According to groas, Google Ads is working only when ad spend connects to real business outcomes, not when clicks, click-through rate, or reported conversions look good. The article recommends evaluating seven metrics that link spend to revenue: true cost per acquisition, lead-to-close rate, revenue-level return on ad spend, impression share lost to budget versus rank, search term irrelevance rate, auction position versus conversion rate, and assisted conversion attribution. It states that trustworthy evaluation requires linking Google Ads to GA4 and, for offline sales, importing closed-deal data back into Google Ads. ## How do I know if my Google Ads are actually working and profitable? According to the article, Google Ads is working only when metrics connect ad spend to actual customers and revenue, not when activity increases. The article recommends seven metrics that separate genuine performance from reporting theater, all focused on business outcomes rather than dashboard activity. An account that cannot show how conversions became paying customers cannot be confirmed as profitable.

The article classifies click-through rate, impression volume, and cost per click as activity metrics, not performance metrics. It states they show that something is happening but do not show whether that activity is valuable or profitable. As an example, the article states a high click-through rate on broad match keywords might mean attracting curious browsers, not buyers.

According to groas, reported CPA measures cost per conversion event, while true CPA measures cost per actual customer or qualified lead. The article states true CPA is calculated by dividing total ad spend, including management fees, landing page costs, and creative production, by the number of actual customers acquired through paid search. It gives an example where reported CPA is $50 but true CPA is $200, meaning campaigns are not performing as well as they appear.

The article states that for lead generation businesses, the share of paid leads that actually close matters more than lead volume or cost per lead. It compares a campaign generating 100 leads at $30 each with a 2% close rate against one generating 40 leads at $60 each with a 15% close rate, stating the math flips entirely in favor of the second. The article recommends tracking lead source through the CRM and measuring close rates by channel, campaign, and keyword group.

The article defines search term irrelevance rate as the percentage of triggered search terms with zero relevance to the business, found by reviewing the search terms report. It states that if more than 15 to 20 percent of triggered search terms are irrelevant, budget is being wasted on clicks, especially with broad match and AI-driven campaign types like AI Max for Search. The article states the defense is a negative keyword strategy with continuous monitoring.

The article describes this pattern as an optimization trap where ROAS improves while total revenue from paid search shrinks. It states this happens when campaigns are optimized into a smaller pocket of highly efficient traffic while ignoring larger opportunity, often by cutting underperforming campaigns to make efficiency numbers look good. According to the article, a healthy account balances efficiency and scale, and climbing ROAS with flat or declining revenue means optimization is serving the report rather than the business.
