For many visionary novice bloggers, the world is not enough. The stash of free themes (more than two thousand themes are available on WordPress.org) does not satisfy their particular desire for look and feel. There are two other options you can take a look at, premium and custom themes. But they incur a cost, sometimes a tiny one, at other times a huge amount.
Working with advertising networks isn’t your only option when it comes to selling ads. If you end up with enough traffic, advertisers may come directly to you and ask you to place their ad on your site. You can also contact advertisers yourself. The biggest difference from the above mentioned option is that there is no middle man, which means you can set your own ad rates.
