One of the first things you will need to do, or possibly last if you need some inspiration, after you pick your niche topic is to pick a catchy URL. You want it to be one that will stand out and that will be easy to remember for those who plan on being return visitors.
To get some ideas and inspiration, take a look at the various keywords that you have singled out for your niche to see if any of those have a catchy ring. You want it to be kind of “used car salesman” sounding, rather than something that is boring or does not have an original sound to it. For example, if your niche is “blah”, you could try “MegaBlah“, “Blah4u”, “HouseofBlah“, or “BlahKingdom“. These will all be original, explain what you niche is, and, most importantly, will be easy to remember.
How easy your URL is to remember is the most important so that your visitors will not have any trouble returning and clicking on more affiliate links!
