I was quite surprised at how many content sites there are now, were you can earn ad revenue from writing useful and unique content on the web, and I was also surprised at the quality of the sites too.

Article content sites have the potential especially if you own one to make a huge percentage of ad revenue for the owner and then filter out lots of ad revenue for it's members, if they provide useful content that is in demand or on a popular topic.

And the best ones are the ones that you can get paid by Paypal as there is no waiting for checks to clear as you know the money is going to be transferred once you reach a set amount, but by far the best thing about joining a content site is that if you really love to write then you can earn a serious amount online, bear in mind you have to write almost every hour of the day at first and promote your links to your articles at every given chance you get, non stop marketing is apparent here.

But a large portion of traffic to your article content if done right would be from the search engines, if you have used the right keywords related to your articles targeted content.

Getting inbound links from other sources such as article directories and blogs and related websites all help to draw traffic to your content sites, aswell as this free advertising and social marketing resources can benefit your search engine ranking too.

A good tip when writing for these content sites is to update your article content quite regularly as this could boost your search engine ranking especially if you are adding more useful content, sites link Squidoo have more resources to add to your articles than any other, oh and here too at Hubpages of course.
