Having a versatile web site is the cornerstone of a successful career as an Internet Marketer. You want to have your own niche and not have a site that's all over the place, but flexibility can come from different arenas and still be germane to your online business.
You never know when one stream of income might produce that windfall you've been looking for. What that does is compound your finances and takes you to unimaginable heights.
Just as one online opportunity can open the floodgates to financial success, you can have another that does just the opposite. When the "well runs dry" with one endeavor, with multiple streams you don't have to worry so much.
If you're selling a wide variety of related products and one sees a drop in sales, you're covered and loss of income is less significant.
Join affiliate programs of other online entrepreneurs whose products are congruent with yours. This should not be done in a competitive manner because you will be selling their products on your site and hopefully vice-versa.
