Your Google account buries you in numbers, and most of them are noise for a business. The danger is that a pretty top-level metric creates the feeling of success while there are no sales. Here's what actually matters.
CTR (click-through rate)What share of people who saw the ad clicked it. A high CTR means the ad is catching the right people. But a click on its own brings no money — this is a metric for optimization, not for a report to the owner.
CPC (cost per click)What you pay for a visit. Useful for controlling spend, but a low CPC with zero sales is a reason to look further down the funnel, not to celebrate.
Site conversion rateWhat share of clicks turn into inquiries. If traffic is flowing but leads aren't, fix the landing page and the offer, not the ads.
CPA (cost per lead)What one inquiry costs. Closer to reality: you can compare this number with your average deal size and see whether the math works.
CAC (cost to acquire a customer) and ROAS (return on ad spend)The key metrics for an owner. CAC is what it costs to win one paying customer. ROAS is how much revenue each dollar put into ads brings back. This is the level where you see whether the business earns on ads or loses.
LTV (lifetime value of a customer)In niches with repeat purchases, a customer doesn't pay off on the first deal. If you count only the first sale, it's easy to switch off "expensive" ads that bring in the most over time.
The problem: businesses report on clicks and CTR because those are visible instantly. The cause: the metrics further down the funnel require linking ads to real sales, and that's a separate setup. The fix: carry the data through to the level of CAC and ROAS — for that, your ads, CRM, and analytics have to be stitched into one system, with the key figures surfaced on
dashboards for the leadership team, where you see the whole picture instead of scraps from different accounts.
