These cost nothing and take an afternoon.
Ask an assistant the question a customer would ask, not the one you would ask. Something like who does this kind of work near this town. Not your own business name. Then read which businesses it names and where it says it got them. Your name may not appear. That is information about where you stand.
Then ask it directly about your business by name and read the answer carefully for things that are wrong. Outdated hours, a service you stopped offering, a town you no longer cover, a description that belongs to a different company with a similar name. Errors like these are usually traceable to something still published somewhere, and they are the most fixable problem on this page.
Look at your own site the way a text-reading system does. Turn off images in your browser, or simply read the page ignoring everything that is a picture. If the services, the areas covered, or the reasons to choose you disappear when the pictures do, then those facts are not really published.
Finally, write down five questions you would want to be part of the answer to, and keep them. That list is your baseline, and having it dated and written is most of what separates this work from an opinion about it.
