My new site is one month old. It had been used to ranked #65 for 2 weeks then disappeared. It seems that homepage (root) not ranked as it used before. I found my site ranked #412 for the same keyword which ranked #65 before but for inner page, not homepage. Homepage is still be indexed and all pages still be indexed until now because of their uniqueness contents. I have continued built links and update unique contents as regularly until today. Only ranking for homepage is disappeared. My question, Is my site got sandboxed or penalized?
well i don't think its sandbox..sandbox (if such think exists) works for the entire site not just the home page...Well your problem might be something temporary and perhaps after a few days everything is back to normal...
