One question that many people consider while creating their internet-based business is this: How many websites to make?
On one hand, some people believe that making more websites will make you more money. For example, if you make $5 a day with one website, they figure you will make $40 a day with 8 websites.
On the other hand, if you make too many websites it can be hard to manage them all.
I feel that you need balance. If you can, I would recommend making more than one website. The reason is that you do not want all your eggs in one basket.
However, I would also suggest that you avoid making too many. Instead, focus more time on each website that you have. I think it is better to have one great website than to have two websites that are only half-great.
I think that it is exponentially easier to promote a better and more helpful website.
