Hi, the suggestion was not to get the quality articles written that take an hour to write each but I meant to change the products descriptions that were copied and pasted with little variation so that they don't look like a copy, paste job.
Now, coming to the de-indexing part, let us look at a scenario:
Suppose I built a website to promote Amazon products through Amazon associates program. I populated its pages using Amazon API through a plugin like WProbot or Protozon. In this case, the content will be purely scraped from Amazon and other places. After a while, I realize that my site has not been performing well in the search engines because of the scraped content but haven't seen any penalty levied or manual action taken. As of now, I have about 3000 pages in Google's index. Now I want to tackle the duplicate content issue. This is what I would do to be on a safer side from a possible penalty in future like Panda:
1. First, will make the top pages unique.
2. Add, noindex to the rest of the duplicate content pages.
3. Keep on making the pages unique in phases, removing the noindex tag to the ones that were updated with unique content.
4. Would repeat the above step till I fix all the duplicate content pages on the website.
It greatly depends on the level of content duplication and few other things so, we will be able to suggest better if we can have a look at the website in question. You can send a private message if you want any of us to have a look at it.
