Basically you need to be in Google News and then the article thats in the news must reach the top 10 in Search Results

Looks like this should cover all your questions

I actually learnt something myself as well on there, thanks for making me refresh my memory

OK so here is the deal, I have spoken with Google's John Mueller about this multiple times.

Your content will indeed be indexed, however Google bot is not as basic as many people think, there are multiple things happening when the bots come to look at your site, one of them is related to the humming bird algorithm. The bot takes a snapshot of what is actually visible on the page and will give THAT content more preference in search. It will also look what is above the fold for customers. So it is advisable to not have a large logo at the top and for some content to be visible without scrolling.

So just because some content is not visible does not mean it will not be indexed but it may be given far less weight than text that is immediately visible.

I hope that answers your question?

Yes, actually John Muller at Google said this is a wise thing to do.

First ask yourself is there really any benefit in your users going to any of those pages?

Duplicate content is not a major issue and can be wildly ignored but many blogs go over the top with tags etc.. Making Google's life harder when trying to make a decision on what content to show for results.

I personally went as far as removing the front end of wordpress completely and coded a very quick and simple version of the front end myself, so it still gets managed using the wordpress interface like a content management system.

Works a treat and the response from Google SERPS was great. Also reduces the amount of pages Google needs to crawl over and over to look for changes. This will see Google returning more frequently to the key pages looking for updates.

Your question is a bit to open ended, what do you want to achieve by knowing this information.

Does a site rank better than you?
Are they doing negative seo to other people?
Do they steal content from people?Are they building links as dofollow from places they should not?

Too many questions to ask before answering such a vague answer.
