Some plr articles has niche articles in them which makes them really good….

I’ve written this series on how to write marketing articles to help YOU write quality content that may help you passively generate traffic and buyers….

Marketing articles are written to presell your customer by creating trust and the resource box is where you place your call to action….

Stacking multiple benefits within a single marketing article makes it easier to build desire BUT you want to focus on only one keyword phrase. This may mean using some benefits in other articles and you may need to use a story to create the desire….

This lesson will get more into the meat of writing your marketing articles for success….

Thank for a Great Post!
The Traffic Queen

As for the Web 2.0 sites you mentioned…I would also watch for Squidoo and Propeller. These two are the best, from my experience.

Also, since you were referring to “gallstone symptoms”, the user could also check out a “misspelling” on the term such as: “gall stone symptoms”, which has even less competition, but using it in the Article should get a little extra traffic.

Just my two cents. Thanks for the info!
