Welcome to the Q&A Forum

How you implement this will determine whether you get more visibility in search results or harm your own efforts on-site and off-site. Here are some key points: Never duplicate the full content across multiple sites if you can avoid that. Duplication of entire entries just forces Google to "figure it all out" and they often do so poorly. Two solid methods that can both work for your overall needs: 1. Create a "Press" or similar section in your site. Each time a new article shows up in a trusted off-site location, add it to your press section.  Either just the Titles and a unique snippet explaining what's contained in the off-site article, or with more info, as long as the info is almost all unique, and not copied from the off-site version. If you generate a lot of these, be sure to use proper indexable pagination in your site's list of outbound press links. 2. Write full blog articles on your own site that link to those articles, but where you go deep in your own content - make it mostly unique and only do so if you are sure it's a quality piece in its own right. Either way can work - the 2nd version is more likely to get both the off-site and your own piece indexed most of the time, however if the "press" versions are also robust, they can rank as well. Here's a screen-capture of how I did that for one of my best articles a couple years ago. The 1st entry is the original article, the 2nd entry is my own site's page about it. HolyGrail3Pack.jpg
