I'm working with a local business with their SEO. Most keyword aren't really competitive, but a few will need a good amount of SEO implemented to get solid rankings. I'm wondering what the best approach to SEO will be while keeping everything professional? I don't want to use a auto-blog commenting service as this really isn't professional for the local business I am working with, and if they ever see comments associated with their business that represents them in a way that is less than optimal my services may no longer be wanted. I know using scrapebox and other tools to blast out a bunch of backlinks works well - and helps fast-track SEO. But what are some of the most effective SEO methods to implements that also allow me to ensure quality articles and any associations with the local business remain professional? Any help is appreciated.
