Google Sandbox and Penalty Checker Tool is a very important tool when it comes to checking our your website is doing in terms of ranking and traffic.Google search engine has been doing a lot of update in it algorithm and past few years they have developed a crawler by the name Panda 3.2
This crawler is very sensitive and many sites have been penalized,Deindexed or Sandboxed
Let go into details and define these three terms
Penalized- Your domain or page wasn’t Deindexed or Penalized, but the traffic you were getting from Google suddenly drops dramatically
Deindexed – When your domain is completely removed from Google. Also known as Banned.
Penalized – When your domain or page still exists but none of your pages can be found through very direct search queries. This penalty can be automatic through the Google algorithm or manually applied by a Google Quality Engineer.
I will share the link to this great tool.I recently checked one of my penalized sites
