just add .jpg at the end of the link - the image is too big to keep
the post tidy...

It's a nice visual "map" to see the different parts of seo...It's
basically a "big picture" of seo aspects.

I know things around here are done a little different from usual but I
think this pretty map can still provide some neat informations and/or
small "aha!" moments

cheers,
