Welcome to the Q&A Forum

Hi All,

I want to copy articles from CNN/Bloomberg/etc and I want to show the content to my users in Lightbox (CSS), but the problem is duplicate content.

Do you have any idea how can I no-index part of page/content?

Yes,
Because I don't have specific URL for the lightbox. it's just a new way to show content...

I'm working on a new website with aggregator of content.
i'll show to my users content from another website in my website in LIGHTBOX windows when they'll click on the title of the items.

** I don't have specific url for these items.
What is the best way to say for SE "Don't index these pages"?
