Duplicate Content Clarification Please
The different sources I am speaking of are:
1) "High level" directories such as, Ezine Articles, Go articles, Article Dashboard, Search Warp, etc.
2) "Low Level" directories - the crappy ones in my article submitter
3) My squidoo lens, hubpages account
4) My blog site
Here are my questions:
A) What I am doing now is section (1) articles, I am changing up and not submitting same content to Ezine, Go Articles, and dashboard, etc. Each one is twisted a bit before submitting, should I continue this or am I wasting my time?
B) Everything else, squidoo lens, hubpages, and my blog all get direct copies of my articles posted with no changes. Any thoughts, or am I shooting myself in the foot?
What is protocol to avoid duplicate content penalties? Please add anything important I may have forgotten.
Thanks
