Your Google Ads ROAS looks great. But is your business making money?
Two Google Ads campaigns deliver the same revenue. But one creates five times as much work for the sales team.
How long does Google Ads take to work?
Published April 2021. Last updated July 2026.
You’ve chosen good keywords, written decent ad copy, set up a landing page that should convert. You’re getting impressions and the CTR looks ok but you’ve still not had any conversions.
You know Google Ads can be a reliable source of new business but it’s been a couple of days (or weeks) and nothing’s happened.
Is this normal or should you worry?
If it’s normal being patient will solve the problem, the leads will arrive in due course. But if there is an underlying problem being patient is the worst thing to do. The campaign won’t get better on it’s own. In fact it’ll get worse, all the while wasting time and money.
Doing Google Ads on your own is hard. It’s even harder when it’s your first campaign and you don't know what to expect.
This should help give you a feel for how long a Google Ads campaign should take to work.
The table below shows the age of the campaign at first conversion. In these campaigns the conversion is someone filling in the contact form - a sales enquiry. Where the age is 1 day it means that the first sales lead arrived on the same day that the adverts started showing.
I’ve included the number of impressions, clicks and conversions over the first 30 days to give you a feel for the size of the campaign so you can see how it compares with yours.
Edit: I’ve had questions about the click through rate (CTR) and conversion rates for these campaigns. Please ignore them. The stats in the table above are for the first month. At that stage we'd not yet made any attempt at optimising the campaign.

About these campaigns.
These campaigns ran on the search network only. The bidding strategy was maximise clicks during the period under consideration. (More info on the launch strategy here.)
None of these campaigns was optimised to produce the first lead as soon as possible, so in some cases we did things like launch a B2B campaign on a Friday when it was ready, rather than wait to Monday morning when it was more likely that it would produce a lead right away.
