The ads on this board appear to be provided by google ads. They really have nothing to do with your local service provider.
The ads will be different for each user. Depending on what you've been browsing on or searching for recently, google's algorithms determine what you might be interested in, and supply ads along those lines.
So, if most of the searches done on your computer are for quilting supplies, you'll see a preponderance of ads for quilting related products and sites.
Depending on your definition of "inappropriate," you might want to check on what you, or others that use your browser, have been looking at recently on your computer.
So, for instance, if you're seeing a lot of ads for places that sell say, air compressors, you might get a clue as to what your husband has been looking at online. :)
