Google’s stance doesn’t change when it comes to automatically generated sites, if a site doesn’t add the required value, it is regarded as spam and appropriate steps are taken to protect users from exposure to such sites in Google’s natural search engines.
What happens if a free hosting site shows patterns of spam?
Webmaster Tools will make strides to tackle only spammy pages or sites. Meanwhile, in other situations, if spammers have pretty much taken over the free web hosting service or a large fraction of the service or a large fraction of the service, Webmaster Tools is compelled to take more decisive steps to safeguard users and remove the entire free web hosting service from its search results.
To protect your website from any of the above, you should adhere to the below:
