I decided to target chiropractors in my area but when I entered chiropractors my city into googles keyword tool it came up with no results for local search volume. What does this mean? Should I continue to persue these clients? I looked in the local phone book and there is almost three pages for chiropractors so I know their spending money on advertising. I just don't want to get a client and not be able to deliver results due to low search volume, any advice would be appreciated.
