I was reading a post on another board about SEO penalties from Google for duplicate content. Initially I thought this was limited to duplicate content within ones own site. However, someone suggested that it relates to duplicate content across all time and websites. Meaning, if I write a paragraph on my website Google compares it to every paragraph written on every page of every website ever created. So, they could tell if something I wrote today duplicated something written by someone back in 1987.

That seems a bit ambitious. Even if they purge websites from their system that no longer exist, that's a lot of data to process.

I know how they analyze sites is top secret, but does anyone have any insight?

I don't have any insights but what you describe doesn't seem accurate. I'm with you that it does seem very "ambitious".

Top secret? Hardly. Use a service like http://www.copyscape.com
Google does similar internalized comparisons.

Teachers use this for term papers all the time.
Site owners use it for finding content thieves (and then deal with it via legal methods).

His point is Google doesn't publish their internal algorithms or methods. People can try to figure out what Google does but they are either guessing or speculating.

The same would go for the Copyscape site. Unless their internal algorithms or methods are publicly published, you don't know how they do what they do but only that they do what they do.

I misread. I thought he wanted to see if sites were stealing his content.
