Hello, Recently someone submitted like 500 products on my site. The problem is being tests, certifications, ... they almost have the same description, only 2-3 keywords (test code) differs in an entire text page. Will Google consider this fraud and attempt to duplicate pages? I really want to display their tests/... but without hurting my site.
I believe the will only index one of the pages. They may consider it a spammy site. I would delete it quickly.
for the products description i think it will sure mark as duplicate content. but if the main page dont have those information that should be fine though.
This is the same problem that most catalog-type sites have. However, people mistakenly talk about Google duplicate-content penalty. There is no such thing. There is a duplicate content filter. Duplicate content withing the same site is just something that cannot be avoided all the time. Google knows this.
