How many negatives should you add at the start?

At the start you add the ones you already know are not customers: jobs, free, recipe, course, supplier and the towns you do not serve. You do not need a list of hundreds copied from another trade. Write twenty terms you would never want for your door and load them before you spend. After three days you add whatever shows up in the report. You start with none “so as not to limit it”, and the first week pays for jobs and Wikipedia. Limiting it was the job. The opening list loaded, and a space on the weekly note to add new ones. The count is not a contest: those searches should not be charged again.
