have a quick question about duplicate content. How does google work this all out? In that on my pages I have a form on each page with the same bit of text explaining it, is this going to count against me? The content on each page is original. Surly most sites might have small bits of repeating text on it, would this count against you?
Google will be able to detect that the text you entered correlates to the form, you won't be penalized for duplicate content.
Google will only hold content against you when the entire (or majority of) page content is duplicated (often including meta tags etc),
So no it won't be held against you! :)
My understanding is that duplicate content on the same site results in Google being confused as to which is the correct result to show, but not necessarily a penalty. Whereas duplicate content on a 2 different domains can count negatively against one of them.
So far this page has offered me the most in-depth explanation.
