I've had a lot of domains sitting for years gathering dust. Many of them ranked somehow even though they had 0 backlinks and not much content. After I add more content and started building links, my top 10 rankings go down to 60, 120, then 300 within a week, and sit there. Is this a dance? How long does this usually last? I noticed the big drop after I built some mediawiki links in the beginning of december... then on dec 6, rankings dropped a lot. But my competition has tons of links from the same wikis, plus much more spammy links. It's funny how it works... Do I just need to keep buildling links and wait it out until the site comes back?
