Hi all. I have a site, which was ranking #2 before the 24-april update. Now it's ranking #6. It's a very niche keyword on a small country's Google. It shouldn't be that hard. I've mainly bought Xrumer, Web 2.0 articles, user signature and PR posts with many OBL. Recently the competitor, ranking #1, has got many footer-links, which seems to have helped him a lot. What do you think I should do / buy?
