Many people mention the idea of diversification online. Their idea is that you can spread the risk among a number of websites in a portfolio. This is true, but it offers a few disadvantages over building and concentrating on one website. I know I’ve tried both ways, and lately I’ve come up with some conclusions as to why concentrating one one website might be the better of the two methods.
With focus, you’re less likely to make mistakes. And mistakes on a website are almost as bad as mistakes made by football players during games. I say almost because at least you won’t end up “knocked out” by a webmaster mistake 
Or at least let’s hope your boss isn’t that mean. But the key to football and webmastering is keen attention to details. The less mistakes you make, the easier it is to get by.
With focus you are more likely to put a ton of creativity into your one main website.
If you work on one primary property, you will devote most of your time to the marketing, design, and business model of that one site. It’s almost bound to do better than 10 or 20 websites you might make. With focus, you can sharpen your one website to a finely honey tip.
Concentrating your marketing and link building efforts to one website will likely ensure success.
If you try to spread your marketing budget around, and attempt to link buiild for too many websites, you might find your efforts stalling out quick. Link building, in particular, can be fatiguing enough with one website, but to multipy the efforts across many has a tendency to leave you burned out and frustrated.
There are a lot of huge examples of companies who’ve done quite well with one domain.
It’s safe to say that Yahoo and Google have done very well marketing under one primary domain. They’ve all managed to brand themselves, and grow rich. If they had attempted to diversify, history might be very different indeed.
There are still tons of good reasons to attempt diversification, and we’ll look at them in a seperate, future post.
