Top Website Niche Categories

Updated September 27th, 2022
There are thousands of categories of websites that we call niches. In this article we will break down today's top niche categories based on available ads.

Depending on the ad network you use you'll have slightly different volumes of available advertisers that are targeting different website categories.

The core idea is that a site about real estate will attract people who are interested in real estate ads.

Here are the top categories we've found.

History of Niches Online

Pre-Y2K the internet didn't have very sophisticated search engines. Much of the internet still relied on manually curated lists of websites that were neatly categorized into topics.

Online marketing experts have termed these categories as 'niches' specifically to mean a sub-sub-category.

Here is a screenshot of Yahoo's homepage in 1999 with some of the prominent directory listings:

There are literally thousands (maybe hundreds of thousands) of niches.

Their profitability depends on the ability to attract an audience and the ability to monetize that attention.
