Besides making money by writing articles for eHow, there is also another way to make some extra money on the site. Affiliate links are allowed on eHow as long as the article doesn't appear to be written just to sell whatever is in the link. Of course, the article may certainly be written for that reason, but it shouldn't appear so. In other words- focus on more than just the item that is being sold or have an affiliate link that is generically linked to the article topic.
If you aren't familiar with affiliate links, here's an article that describes how affiliate marketing works. An easy way to start in affiliate marketing is to sign up with Amazon and choose books that pertain to the article topic and to put an affiliate link in the Resources section of the eHow article. For affiliates who want to earn a larger commission percentage, there are ebooks and other digital products that usually pay more on each sale. However, with Amazon links, customers click on the link to see the product, but anything they buy on Amazon will earn you a commission.
I have links to books on several of my eHow articles, links to CDs on articles elsewhere and a product "carousel" on another one of my blogs that has links to books. Last month, someone went through one of my links somewhere and ended up shopping in other sections of the site. This has happened many times before, and I've earned commissions for people's snack foods, toys, household items, etc. But last month, someone bought a $1,000 TV and a Blu-Ray disc player, earning me commission on all of it. That's the power of Amazon affiliate links.
Unless you really push affiliate links, the income you can make from them is usually far from steady. For me, it's been hit or miss each month. I try to link only to things that I think are genuinely helpful to those who are interested in the topic. At the top right of this blog is a link to an ebook that I think is very helpful for making more money on eHow, and it has a great reputation from eHow writers.
Some months a few bucks in affiliate sales commissions come in. Some months, it's $25-50. So, for me, it isn't much, but it's also not much trouble to put the links there. Like eHow articles, once they're in place, they will keep earning for you for as long as they're there, and you don't have to do anything else to keep earning from them.
