My strategy untill recent was building small webstes around a small niche. But lately I started to think it might be a good idea to start a few large authority sites. I registered 7 domains in the field of money, health, law, travel, electronics, business and gadgets. Each will be a portal kind of site with lots of categories. The first I started to work on was the money site at http://moneyfied.com I just added 3 posts there. One about the current credit criss, buying stock in the bear market and one I like is called warren buffet quotes
The main reason why i shifted from small sites to large is the abilty to build backlinks to one point that will spread out over the whole site. With a lot of small site your attention is to much all over the place that it’s easy to stop doing all the things you would like to do in promoting a website.
But I do not say I will stop building small sites as that is a profitable way also but I will shift my focus more on the large sites.
