This is the single most common thing we find wrong on a Google listing, and it is one field. The link is how an engine reading your listing reaches the pages that answer the question. Pointing it somewhere else breaks the whole path.
What tends to be in there instead
A website you replaced two years ago, still live on an old host.
A Facebook page, because that was the only thing online when the listing was created.
A directory entry or a page a marketing agency built and still owns.
Nothing at all.
All four have the same effect. Anything reading your listing, a customer or an AI, arrives somewhere other than the pages you have been improving, and the credit goes to whoever owns that page.
Changing it
Open your Google Business Profile and find the Website field.
Set it to your own domain, with the full address including
https://. Then click it and check it loads.Use the same address the rest of your listing implies. If your listing says one domain and your structured data says another, you have moved the problem rather than fixed it.
What it is worth
It carries one of the heaviest weights in the Local presence score, and the finding prints what it is worth on your own scan as X of Y points. It is also the highest-value minute on the whole list, because it is what tells Google, and everything reading Google, that the listing and the website are the same business.
