Gary Illyes’ Post

We've heard (and also noticed) that some sites "rent out" their subdomains or sometimes even subdirectories to third-parties, typically without any oversight over the content that's hosted on those new, generally low quality micro-sites that have nothing to do with the parent site. In fact the micro-sites are rarely ever linked from the parent sites, which don't actually want to endorse these often questionable sites. The only reason the owners of these shady (?) micro-sites rent the sub-spaces is to manipulate search results. Those of you who let us know about this, sent us plenty examples, and even blogged about it: thank you, it helped us tons! Those of you who rent out sub-spaces of your sites to third-parties with no oversight of the content, please have a read: "If you host third-party content on your main site or in your subdomains, understand that such content may be included in site-wide signals we generate, such as the helpfulness of content. For this reason, if that content is largely independent of the main site's purpose or produced without close supervision or the involvement of the primary site, we recommend that it should be blocked from being indexed by Google." https://lnkd.in/ddcG_5Xi

Took some time (years) for Google to start doing "something" about these practices. Unbelievable.

Hi Gary, this is really interesting. What happens in the case where a brand may have been hacked and they have sub-domain takeovers they are not aware of? Would this potentially get them penalised? And in this case, it could be abused by black-hatters trying to attack competitor sites.

Does this mean that Web hosting sites like WordPress-dot-Com should be concerned?

Gary Illyes Am I correct in concluding that site-wide signals are generated on the host level = apply to all subdomains? Or does this only apply to some signals like the helpfulness of content?

Just to verify. Does this include media sites and publishers?

What about SaaS websites where the free plans are on subdomains (like feeds), or hosted courses or even support documentation sites where you get a subdomain on a TLD? Gary Illyes
