Google web spam team has been on a crusade to murder the SEO industry and as a result, unstable rankings are now common. Its not very hard to take down a competitor site these days. Just buy a few sponsored wordpress themes with their keywords on the footer and give it away for free or spend $50 on fiver for thousands of xrumer links and within 6 months, the site is TOAST (won't be on the first 20 pages guaranteed).. This works every time.. Google knows this, but to them its small collateral damage.
