Even though we can post links on sites that allow it such as classifieds and even other web sites we have, I'm finding that paid advertising is more effective and can grow your site faster. I try to use the best keywords for the sites I build. I'm realizing that the web hosting business takes a lot of time and energy and not a lot of profit. I'm delving into other online businesses and I advertise my web hosting site on them also. This is a strategy I have used for awhile even when I didn't do a lot of paid advertising but it didn't bring the results that paid advertising does.
