Last Friday, Google had delisted Search Engine Land from its index and search results by accident. In that situation, not a single page from from the site showed up in Google search.
When Search Engine Land got a response from Google that morning, They were told that its “system misidentified the site as being hacked” and thus was mistakenly removed from the index. According to Google, it caught and fixed the issue on its end early that morning, removing the hack classification, although the site didn’t return to the index until about 5:30 pm that evening.
To those in this industry and community, the irony of a search engine marketing site getting delisted (even by accident) by Google was certainly there.
So what are the details of what happened? How did Google respond to the follow-up questions asked by Search Engine Land, and what SEOs and webmasters can learn about the day the site was delisted.
