Duplicate paragraphs on different page?
 

Say I have a couple of paragraphs that are identical.
I place these identical paragraphs on several different page of the same website. Other than these specific paragraphs, everything else on each pages is different.
How will the engines judge that?
Will they consider these duplicaste paragraphs as valid content?

They'll count them as duplicates. There are ways around this but you are probably better off just writing different stuff.
