Paid or Free Advertising? Which is best to build an email list? – It’s up to you really and depends on whether you have a budget available to advertise.
Of course there are free forms of advertising everywhere you look online, but is it really effective? The first thing you need to do is to test every source you find. If you get some success you can keep on advertising at the same source, but be sure to track your clicks so that you can “weed out” the best ads and get rid of the ones that don’t work so well.
