When Google Ads is the right answer
Google Ads works on one thing: somebody typing what you sell. If that search happens, you can be there within the hour. If it does not, no budget creates it.
It works when a customer is worth more than a few hundred pounds, when somebody answers an enquiry the same day, and when the budget can run ninety days rather than four weeks. It fails when nobody searches for the category yet, when the margin cannot carry a click price competitors have already bid up, or when enquiries land in an inbox nobody opens until Monday.
That last one costs more accounts than any bidding mistake. A fast lead handled slowly is a lead you paid for and gave away.
What actually decides what a click costs you
Four things, in the order they matter.
Who else is bidding. A click price is set by an auction rather than a rate card. Where a customer is worth thousands, clicks are expensive, because they are worth it to somebody.
How well the page answers the ad. Google charges less for an ad that sends people somewhere relevant. It is also the lever nobody pulls, because the page sits outside the ads account and no one owns it.
Which searches you allow. Broad matching to save setup time is how an account ends up paying for searches the business cannot serve. Every one of those is a click bought and thrown away.
What you have told the account to optimise for. Smart bidding is obedient. Ask for form starts and it buys form starts, including from people who will never answer the phone.
So the audit reads the search terms report before it reads anything else. It is the most useful screen in Google Ads and the least often opened.
What the £31.4K account actually shows
Two Google Ads accounts measured here, side by side. One produced 2,410 conversions at £19.21 each from £46.3K of spend. The other produced £31.4K of conversion value from £4.66K of spend, a 6.74x return, in an eight-day window.
The second number is the one people quote and the first is the one worth studying. Eight days is a snapshot, and the page for that account says so. What both have in common is that the tracking was fixed before the bidding was touched, so the platform was told what a real sale or a real enquiry looked like and went to find more of them. That is the order every account here runs in.
Where the line is
Search advertising captures demand. It cannot create it, and if the search volume for what you sell in your area is not there, that gets said on the free review and no budget is taken.
A lower cost per click is not the goal. That number can always be improved by buying worse traffic. The set reported here is cost per qualified enquiry, the share of enquiries the sales team judged worth having, and the cost per customer that falls out of the two. Those three move together or something is wrong.
And nothing is billed for a lead that misses the criteria you agreed. The risk of a bad lead sits on this side, which is the point of pricing it this way.
Google Ads sits inside media buying, which is where the same budget is run across Meta and paid social when that makes sense. Buy the search, not the click.
