Remove all defective and/or thematically irrelevant links.
Added a privacy policy.
Added a creativecommons licensing statement.
Checked robots.txt -> nothing wrong.
Checked safebrowsing tool -> nothing wrong.
Checked meta tags -> nothing wrong.
Added noindex,follow to news index and category pages.
Added rel=”nofollow” to a button of a thematically relevant high-quality top50 listing.
I NEVER purchased or sold a SINGLE link.
I added ‘nofollow’ to my free thematic business listing, just in case G might be thinking I’m selling these positions.
Built a couple of nice high-quality links through guest posting.
Added new quality content on a regular basis.
Added a tagcloud to improve crawlability.
Added a great deal of relevant wikipedia-like internal linking (as per Ronburk’s classic post).

Added the new canonical tag (yep, I am desperate).
Removed interlinking (it was only minor anyways).
Added valid XML Sitemap.
