Maybe your site disappeared from the Google index, among other problems and you need to get a Google Site Reconsideration. Considering that most people’s websites get a lot of traffic from Google, it will be important to get the site reconsideration.

Watch this video if your site has stopped showing up in Google and you require reconsideration. There are many reasons why this could have happened and the video is the official way to help determine what to do.

Overall there isn’t a lot of new information that you couldn’t read straight from Google, but still if you are unsure or a newbie in site reconsideration I would recommend this video.
