Niche product returns just under 80,000 results when searched for in google uk.
I have a few sites with only a few pages that generate a decent amount in terms of revenue.
Obviously if you add more pages and have more content, you will get more traffic, but some people prefer to designate their other domains/websites for that purpose.
As long as those three pages arent only directories and links to other websites you should be fine as long as you get good backlinks as Tedster mentioned.
