Too Good to Be True: Why Promises of Fast Google Ads Results Are a Trap

Too good to be true: promises of fast Google Ads results

Recently Facebook showed me an ad from an agency. They were boasting about one- or two-week case studies: here’s the launch, here’s the ROAS, here are the leads. And it works, because there’s a sucker born every minute. There will always be a business owner who wants to hear “results in a week” and will pay whoever promises it.

I don’t promise that. Below I explain why, with numbers from my own projects.

Launching fast and earning fast are different things

Fast does happen. I’ve launched ads in a single day, and Merchant Center for one store passed moderation in three days without a single suspension. The first leads can come in the very first week.

But a launch is the start of data collection, not a result. In the first weeks campaigns are learning, the algorithm searches for the audience almost blindly, the first leads are expensive, and negative keywords are collected from real search terms. A week’s statistics are noise.

Across my 150+ projects the picture is usually this. The first month is technical work and data collection. The second is analysis, testing hypotheses, optimization. The third is scaling and a stable result. Sometimes faster, sometimes slower, but not in a week.

What happens if you judge ads by the first month

Dentistry. First month: 6 leads at UAH 3,500. Second month: 17 leads at UAH 1,700, with no budget increase. The cost per lead halved simply because statistics appeared and we tested hypotheses. If the client had judged the ads by the first month, they would have gone looking for the next contractor and started all over again.

The mattress store was similar: the best numbers didn’t come right away, but after several months of work on the feed, analytics and CRM data.

And one more trap: pausing. At the employment agency the ads were down for more than two weeks because of a domain suspension. After the relaunch the cost per lead at the start was frankly sky-high. The campaign essentially started learning again. Whoever turns ads on today, turns them off a week later “because it’s expensive” and turns them on again a month later pays for the learning every time.

How “one-week” case studies are made

A one- or two-week case study is either chance or manipulation. There are plenty of ways to show a pretty number:

  • take the best week instead of the whole period, for example the peak of the season;
  • mix brand traffic with non-brand, because brand is always cheaper;
  • count everything as a conversion: phone clicks, repeat calls, the WhatsApp button;
  • show ROAS without margin, even though with a 15% margin even a 714% ROAS earns pennies.

I write case studies over periods from three months to several years. The seasonal gifts project in Israel covers a full season, and it’s already our third season working together. And not every case is a success — that needs to be talked about too.

Who really pays for “fast”

A contractor who promised results in a week risks nothing. If it doesn’t work, “the niche is difficult” or “you need a bigger budget”. The business owner pays: first with money for ads that didn’t have time to learn, then with time spent looking for a new contractor.

A sushi delivery owner once came to me: “I’ve already had 15 contractors, nobody can do anything.” I asked about repeat orders, average order value, other channels. The answer to everything was “I don’t know.” He was looking for a 16th contractor who would finally make it happen fast. The problem wasn’t the contractors.

What to ask a contractor before starting

Ask two things. What exactly will be done in the first month? And by which numbers will you jointly judge the ads after three months: leads, sales, cost per customer? If the answer is “you’ll see results within a week”, better not to pay.

FAQ on the topic

Frequently asked questions

How long does Google Ads take to deliver results?
Usually two to three months. The first month goes to setup and data collection, then optimization and scaling. The exact timeline depends on the niche, budget and number of conversions.
Why are the first Google Ads leads expensive?
At the start campaigns are learning: the algorithm doesn’t yet know who your customer is, and the specialist is only collecting statistics on queries and negative keywords. As data builds up, cost per lead usually goes down.
Can I pause ads for a few weeks and then turn them back on?
You can, but after a long pause the campaign effectively learns from scratch, and for the first days the cost per conversion will be higher and unstable.
How can I tell a Google Ads case study is manipulative?
Look at the period (a week or two is too short), what counts as a conversion, whether brand traffic is separated and whether margin is taken into account, not just revenue.
Can a specialist guarantee Google Ads results?
What can be guaranteed is setup quality, transparent reporting and systematic work. A guarantee of a specific number of sales within a specific time is a red flag.
