Scraping services on their own are a viable business product, but the power to assign metadata and contextualization is where the unicorn lies. The service itself will always be in flux because of how freeform hypertext is as a schema. So many other comments here reflect that better than I could. The fact is that any chunk of data you're handing over to clients still needs to be handled by their team and in my experience reality often falls short of expectations. If you can somehow deliver them something cleaner (or even something that can help them reach conclusions faster), then you have a product with a high value prop.
