When we audit a business, we look at the website before we start paying to send traffic to it.
If it is clearly not up to scratch, we will say so. There is no value in spending a client’s ad budget proving something we can already see.
But sometimes the answer is less obvious. The website may look good. It may be relatively new. The business owner may feel it has worked reasonably well in the past.
That is where Google Ads can become a useful test.
Importantly, it can bring new people into the business who are actively looking for the service but have no existing relationship with the brand.
That is different from referral traffic.
A referred customer might arrive at a fairly average website already thinking, my friend used these people and said they were brilliant. The website only needs to avoid talking them out of making contact.
A fresh lead from Google arrives without that borrowed trust. The website needs to communicate the business clearly, demonstrate the right level of expertise and quality, answer enough of their questions and give them a reason to choose it over the other businesses in their search results.
A website can therefore appear to be working perfectly well for referrals while doing very little to convert people encountering the business for the first time.
If there is genuine uncertainty, a strategically built Google Ads campaign can help us find out fairly quickly. We can send relevant, buyer-intent traffic through the site and see whether those fresh prospective customers take the next step.
If we already know the website is not ready, we fix that first.
The point is not to waste money testing for the sake of testing. It is to use real customer behaviour when the answer genuinely is not yet clear.
