Hi, I've a 3 months old site which was ranking on 4th and 5th pages on google for 2 keywords without any work. But still it wasn't ranking at all on yahoo. Then, I did a SENUKE X link pyramid blast. Soon, after the blast it completely disappeared from google and appeared on yahoo on 1st spot. A week later after another link building process, it completely disappeared from yahoo but came back in google on page 6. It has never been the case that it's ranked at the same time on google and yahoo both. Both the search engines are replacing the positions alternatively. What am I doing wrong here? Why is the site ranking well on one search engine and lost completely on the other one. BTW, keyword is low competition keyword with 14K exact searches. Anyone experienced this? Any help?
