The website is selling an ebook to learn how to bartend. I do not want to post URL because it may seem I am spamming. Most directories I can not find a good category. Is it better to put it into a business opportunity category, home category, food and beverage, how to (most don't have), or some kind of education? Any help would be great it just seems like a niche that is hard to find a specific spot. Thanks.
"How to" would be #1 if they have it IMO. Education, Hobbies, Food and Beverage or Alcohol would be a good second choice I think
You already have some good categories in place. As snowbird said, some directories have ebooks category. I am not sure you can put it in business opportunity (though the category is available most of the times). Unless the keywords are right and language on site also talks about it as a business opportunity, many directories will not like submission to 'business opportunity'.
lol I own the rights to the ebook(it isn't a PLR or MRR) if someone else is using it and giving it free I should be doing a cease and desist against them. Don't think there is much I can do though if it is being downloaded through torrents.
Most niche websites fit in two or more categories. My advice is don't sweat it, but mix and match. I'd probably suggest something like Business > Retail > Books, but other people will have different views. The important thing is to try to find whatever seems most relevant, and let the directory editor take it from there. Editors will only delete your link in annoyance if it's in a totally off-topic category, like Golf or Hairdressing.
