Writing for a wide variety of sites if very helpful for making a recurring, passive, or semi-passive income. Hubpages is one great site to write for. They let you organize a complete page that has text, pictures, and even capsules containing eBay affiliate or Amazon affiliate options. This lets you make money with a portion of Google Adsense (60%) and eBay and Amazon programs. You control what ads are on your page (except Google Adsense ads) and how many Google Ads are there.

These pages are fun to set up, can be about almost anything (no adult material or hate!). They can include personal touches, and be worth a nice income!

Hubpages is one great option for increasing the number of websites you write for.
