What a grind.. Look at webmaster tools - Filter by Pages - Type in the URL of each article. See what whats rank or not ranking on that article (Try to SEO what's ranking to rank better) If nothing is ranking then hit keyword planner tool and find some good keywords, related to the article. Set Title, H Tags, Bullet Lists, Em's, Bold's - Incorporate the keywords Set the page URL with the Keywords in Excel (for off-page Anchor Linking) Rinse Repeat. Wish I would of did this when I first wrote them. I have a feeling when I'm done, I'll have to re-evaluate in a couple of months and repeat the process.
