Renewal of domains.
The thing with maintaining a large number of sites is that you have to be ready for the time when you will be renewing the domain names attached to each.
I know some bloggers who made sure to register their domain names for three to five years in one go. I couldn’t do that lest I will be out of money in my online account. So what I do is I register for a year and wait until its due date to renew each. Of course, there are domain names which will expire on the same day so the renewal cost can be too much for me.
Well, what I am trying to say here is that be sure that you have the capacity to maintain a site including renewal of its domain name before you start one. You can choose to go the free way with Blogger DOT com and WordPress DOT com but if you want a personalized site, your own URL, that is, then be prepared to shell out a small amount every year for the domain name renewal.
I am telling you, if you have more than three domains to renew in one go, it will make a big dent on your pocket unless you have a discount coupon code to use.
