Hi Pete. Using rel=canonical would be a better implementation as your site showing up for a search on these articles is perfectly acceptable since they're about your site. There are also several other design ways in which you can link back to the original published article...
- Annotation. Instead of republishing the entire article you can quote bits from it and highlight what service/product/thing your company does in relation to the quote. It could perhaps be an expansion like, "We also make this in custom colors..." a clarification, "This is now a permanent service..." or any other applicable detail really.
- Screen cap. Some sites churn through articles so an archived screen grab of the article is nice to show the press you got. Photos are especially handy for when you show up in print.
- A brand scroll. Lots of sites add the logos of well know brands that have written about them titled something like, "What people are saying" and then showing the logo of various sites: the verge, wired, tech crunch, etc. and linking to the article via the logo.
So I'd get rid of the noindex tag. Me finding your site as a result next to the Daily Business Review site would make my user experience better as the search is returning the correlation even before I click through to read the sources.
