1.) www."my-city-town".com which has all the content.
and then on every page has links to below.
4.) www."name-of-my-city"-info.com which has
either has duplicate pages to 1.)
or just points content back to 1.)
What is the difference in 4.) just being a link farm?
How g--gle can't see the duplicate content is beyond me... exact pictures and words.
Mind you.. this is a competitive market.
Maybe it is because g--gle is ranking sites with the "name" as the domain more valuable far above any algorithm and duplicate content can filter out.
