I'm the webmaster for a sanitation company who provides portable toilets to construction job sites. They are finding their site ranking high for terms that include wedding. Since that is a service they don't want to provide they've made sure those . They do have a page for special events, which they do service. With them being listed for this term it leads to a lot of telephone calls and emails that waste their time.
The customer would like it if their site was not listed when search terms include the word wedding. Is this possible? I cannot find anything direction online to not include a keyword in a ranking. I've used a robots text to not index their special events pages, but they still are ranking #2 for wedding portable toilet.
