When I look at a Google Ads account for the first time, I do not start with the ads or the keywords. I start with the conversions column. That one number tells me whether the whole account is being run on real information or on guesswork, and more often than I would like, it turns out to be guesswork.
The reason is simple. Google Ads conversion tracking is the least glamorous part of an account, so it is the part most people skip over or set up in a hurry. And once it is wrong, everything built on top of it is wrong too. You can have brilliant ads pointing at a great website, but if the account is counting the wrong thing, you will still end up spending money in the wrong places.
What conversion tracking actually is
Google can see two things on its own: how many people clicked your ad, and how much that cost you. What it cannot see, unless you tell it, is what happened next. Did the person ring you? Fill in the form? Book something? Or did they glance at the page and leave?
Conversion tracking is the bit of setup that closes that gap. It sends a signal back to Google that says "this click led to an enquiry." Without it, Google is working blind, and so are you. You are looking at clicks and cost and quietly hoping the good stuff is happening somewhere off screen.
Clicks are not customers
Plenty of business owners judge their ads on clicks and impressions, because those are the numbers Google puts front and centre. The trouble is that a click is just someone arriving. It tells you nothing about whether they became a customer.
I have seen accounts that look wonderfully busy, thousands of impressions, a healthy click-through rate, and an owner who cannot work out why the phone is not ringing any more than it used to. The clicks were real. They were just not turning into anything, and nobody was measuring the part that mattered.
The three ways it usually goes wrong
The first and most common problem is that conversion tracking simply is not there. The account was set up to get ads live quickly, tracking was left for "later", and later never came.
The second is more slippery: the account is tracking something, but it is tracking the wrong action. This is the one that catches people out. I have seen accounts counting visits to the contact page as conversions, when reaching a page is not the same as sending the form on it. I have seen every click on a phone number counted, including on desktop, where almost nobody actually rings. One account I looked at was proudly reporting forty conversions a month, and when we traced them back, most were people opening a PDF price list. Useful to know, but not an enquiry, and certainly not something to bid harder to get more of.
The third is the opposite problem: it counts too much. Spam form submissions, accidental double clicks, the same person counted three times. The number looks great in the report and means very little.
