I'm confused...if our sites aren't high authority then where does one find a site like this and why would we want to publish an article like this on someone else's site? Sorry if that doesn't make sense but I'm a little confused by this tip.

Also, if no one is searching for these low competition kws, and we end up on page 1 what difference does it make if no one is actually looking for this information? Confused again :/

Definitely not trying to be a smart ass just trying to understand this a bit better....and now off I go to read about invisible keywords :)
