Do we know if Google treats links placed in articles that appear in article directories (eg EZine Articles) as being self awarded (ie manipulative) and therefore subject to a Penguin penalty?
Back in 2008 I wrote 13 unique, 500 word plus articles with keyword links in the Resources block pointing back to either home pages or money pages of sites that were subsequently hit by Penguin algo updates (no manual penalties).
I've recently de-optimised the anchor text of those links but I'm wondering if I should just delete the articles altogether? I'd like to keep them as they are genuine sources of well researched information, but if Penguin is engaging in a slash and burn exercise involving the links appearing in article directories, then surely the articles have become a self-inflicted wound.
