I know a lot of people here are advocates of having lots of sites for diversification, but some have a small number (probably one in many cases) and are doing very well.
I know there's no right and wrong answer, but wondering if we could have a discussion about many versus few, the pros and cons.
My thoughts (as someone with two main sites, and a few trivial ones I haven't really invested in, with returns that reflected that):
On the many, diversification seems the main benefit. Having lots of sites means when one gets hammered in the next algo update or whatever, then it's no big deal. Having many also increases the chances of getting a big winner - I think we all know that some sites just won't do well. A friend of mine, a very successful investor, said from 5 investments, 1 will do much better than expected, 3 will do about what you expect, and 1 will bomb. That is in line with my broader experience in life. Diversify gives you a better chance of finding that 1 good one in 5.
On the few, it seems in my experience the deeper you dig into a niche, the more opportunities present themselves. I'm sure some sites have limits, but most sites it seems to me that new opportunities, new ways to expand the audience base (and thus increase traffic), and new ways to monetise that traffic are constantly appearing. But of course, this takes time, time that could be spent... diversifying.
So, I open the floor, what are your thoughts and experiences?
