I’m on the path of completing more mini sites for the domains I own. This way I won’t have so many parked domains, but rather domains that are indexed and getting some traffic for intended keywords.
In addition to developing the domains, I’ve decided I have to take a more active role in link building. I’ve heard of some success with article submission sites, but only if it is done manually and slowly. I’ve compiled a list of article sites and have started to setup logins. I’ll have to also write content for the article submissions. A small increase in rankings for keywords may be enough to make these sites “successful”.
