I'm having a bit of a conundrum with Press Releases:
I recently sent a press release on PRWeb (which I personally think is just "average" compared to others as it focuses mainly on the CBS network and is not focused at all unless you pay for an expensive release) and got over 100 incoming links from high PR news sites (according to Webmaster Tools) but these links had PRWeb in subtitle, so for all I know these were syndicated releases and not "Pick up By" as PRWeb reports.
- Will this affect Page Rank value or rankings for any keywords?
- Are these links treated only as temporary links or permanent back links? (I know sometimes they appear in Google News or Yahoo News, but disappear the next day)
Was it valuable to the company?
Our business is in health sector exclusively on East Coast U.S. and the release was seen all over the world and not one of the links coming back was from a health-related section. They were high rank online sites, but is there value in such links?
added 11/30: I was reviewing competitors' link backs I found they did a lot of press releases and gained a high-level link back from each one. These were the best/highest-authority links they had. The syndicated releases were not even listed anywhere. And then I reviewed their SERPs... and guess what, their ranks increased with each one. (So I don't think "duplication" is an issue. If anything only the syndicated copies were penalized, but not the original one)
