An update from me. This thread has really got my momentum going. Although I haven't done enough with santaradar.net (still not got it listed), I've spent the week coding up a landing page "poll" system and launching a topical PPC campaign -> Poll -> Email zip submit, wired up to Tracking202 for analytics. Result - got 120 clicks so far, and at or above break-even (maybe a profit of $1). Things should improve after I've trimmed my keyword list a little.
I'll get back to looking at the SEO on the site tomorrow
