Is Google able to differentiate this flaw and not mark it as a duplicate c?
I think so. I also think that sites that are successful at this are also doing the following:
1.The actual article page has a unique Title and Meta description, not the same as the Title and description from the index page. 2.Their content changes often, they post two or three times or more a day. 3.They tend to keep just a few of the most recent articles on the index page, not dozens.
In addition to those that I suggest above, they are also most likely classified as authority sites, which tend to let you break a few minor rules.
