Pages mirrored on unknown websites (not just content, all the HTML)... blackhat I've never seen before.

Where in google search console are they reported?

Also to be clear, nothing has happened to your site.  ie traffic has not changed. However you have found "strange" links in search console?  Which do not click through to anything?

Or as I am still not clear - have you found another domain, that mimics your site that you can actually see?

[2mlab]

In the console there is a section called (translating into English) "Links pointing to your site"

Traffic has not changed, in fact these do not appear in GA referrals.

I can see all these domains, either the mirrorer paged, or the actual genuine pages pertaining to them originally. You cannot reach the mirrored pages via the menu in hp

[ClaytonJ]

That console part provides clickable links.  So that goes back to my original question.  Can you click through to the domain and see a mimic copy of your site? Or is it simply showing you a link that clicks to nothing?

[2mlab]

Yes, sorry but I thought that was clear from the beginning.

If I click to the console links I am directed to the mirrored page in these domains. That's exactly how I saw them, otherwise I coudn't discover them

[ClaytonJ]

I am honest I am still a little puzzled. But if what you are describing is what is happening.  Something very strange is going on. I have not heard of it before.

A totally different domain, that you did not build is linking to your site with the exact copy of a page that it is linked to. If that is the case, your site is being specifically targeted. Someone has to have gone out of there way to copy your site and then re-build it on a different domain.

This is what I would do:-

I would contacting google asap.

Can you find who owns the site on whois?

Check the wayback machine to find out what the site was previously

User open site explorer to track the nature of the links on the other domain. .

And wow... that is unbelievable if it is correct...

As far as I know website scraping is not uncommon, apart from the backlinks

[ClaytonJ]

Some basic scraping maybe common, but they have gone out of there way to backlink to you...

Have you checked there metrics on open site explore...?  Checked whois?

Hi,

From what I read it looks similar to these cases - https://moz.com/community/q/getting-different-search-queries-in-google-webmaster & http://moz.com/community/q/chinese-site-ranking-for-our-brand-name-possible-hack

In these cases - sites where hacked using a vulnerability in a Wordpress slider - they copied sites they wanted to target on to some of the hacked domains and used other hacked domains to point links to them. At that point they were trying to redirect traffic from genuine e-commerce sites to bogus ones.

You could try to contact the site owners & tell them they have been hacked. At the same time file a complaint @Google 

rgds,

Dirk

We see scraped content all the time. Occasionally we see scraped HTML in full form but slightly edited.

In general I'd do the following:

• Disavow those domains in GSC. Also consider disavowing any domains pointing links at the mirror sites. It could be possible that they are building up junk links to a mirror site which canonicals your site. No idea why anyone would do that but worth covering your bases.
• Submit DMCA notices to Google, their webhost, etc.
• Take a look through server logs for anything screwy. If you see tons of weird traffic from countries that aren't relevant to your business, you might decide to block them with your .htaccess file.
• Certainly make sure nothing has been changed on your own site (canonicals, common Wordpress hacks, etc.), though nothing is suggesting to me that that has happened.

Other than that I would just keep an eye on it and keep an eye on Google Search Console.

[KaneJamison]

One more thing that could be a long shot but is worth keeping an eye on: If someone had zero ethics and wanted to steal your links, one thing they could do is reach out to webmasters that link to you and pretend to be you, and claim that the mirror site is the new version of the website and ask them to change their links. Once complete, they'd redirect the mirror site to their own commercial site.

So, keep an eye on your own link profile and theirs, just to make sure none of those links are changing.

Thanks everyone, I'll do more research and update all

[2mlab]

The links actually are just in some forms
