I saw my traffic get halved today. There seems to be little to no chatter of an update, which leads me to believe that this is the result of a site specific penalty of sorts. I searched my own domain name, to see what would be returned by Google and to my surprise the result had changed considerably from the last time I checked (several month ago). My website appeared in the top spot as usual, my Facebook page in position 2, followed by a bootleg pinterest page that claim to be from my website, but thereafter every single link was from a series of related spam domains. The description in search appears to be scrapped content from my website. I believe that the sites were hot-linking to images, but I put a stop to that a few weeks ago. But when one clicks on the links it leads to Adult content, or some kind of "You Win scam" site. All the links are similar.
If I type the links to those spam-pages into page-speed insights the preview shows "legitimate" content, not necessarily my content but nothing spammy.
Typically I would just ignore crap like this, but the results for my domain name are overrun by these websites, the typical sites that legitimately linked to me are nowhere to be seen. Today's drop in traffic has got me worried now that this has resulted in a penalty of sorts.
I have no notifications in GSC, and there is no sign that my website has been hacked.
Also, I had been experiencing a slow bleed in traffic over the past 8 to 12 month, and I have seen these pages appear in my link profile in GSC over that period, so I assume that this has been building since a while and now has reached its tipping point.
I'm at a loss as to what to do about this. My site has not been hacked, there are likely hundreds of these spam-domains pointing at my website, I doubt disavowing them will do any good.
Any ideas?
