How to use a visited article with no sales?

Question

Search Engine Optimization

There is a small site that sells the service. There are several articles where organic traffic goes.
And there is one article that generates 70% of the traffic, but the problem is that it seems to be on the topic, but people come to read it (and even call from other cities with questions), but not for ordering a specific service that we offer.
Question: how can such an article still be used in favor? Maybe some links from it will have weight, or you will advise something like that.

Answer 1

You know, there is a good anecdote about the Odessa brothel and about girls who stop generating income.
In other words, consider offering a service that brings you 70% of your traffic, and not what you specialize in now.
