In the wedding niche, you could consider these micro-niches – wedding flowers, honeymoons, wedding dresses, wedding speeches, cheap weddings, wedding favors, etc, etc. Of course once you have found a niche that you want to market to, you need to consider how to monetize it. Creating a product or content yourself that is of suitably high quality to make you money involves a lot of research and development time (anything from a few weeks to many months). If you are selling a product as opposed to making money through advertising such as Adsense then you will also need to write sales copy.  There is one main problem though and that is the fact that pretty much every other online marketer is working in this niche as well, and with so many marketers targeting the same group of people online it is becoming increasingly hard for the smaller, lesser known names to get their products and services seen amongst sea of other offers from competing marketers. The make money online niche is very overcrowded.
