The problem with SEO tools is, it might take some time before you can get around it. As you use it, you will experience bugs and issues that you have to fix. It might not be able to crawl pages if the links in the site are hidden in the JavaScript elements, and a lot of other technical errors that you might stumble upon while you use it.
If you are an owner of a small business, I would highly suggest that you work with a team to handle it for you.
