In Google Search Console I saw that there is a site that is being reported as linking lots of times (100s) to my site and that site is a non related site so I investigated in case it was a candidate for disavowing (it is a e cigerette / vaping site and my site is travel related). I found something very strange though.
The "linking" site (lets call it LINKSITE) and my site both use the same theme and also have turned on the same extended-reviews extension that comes with the theme. Somehow this is causing google to see that each LINKSITEs review pages are somehow linking to my review comments pages , but I cannot see how they are in any way and dont believe this is the case. Its confusing to explain but will try with some examples:
IN GSC it list LINKSITE under the Top Linking Sites section, I drill down one level and get a list of all of my pages under the Top Target Pages section that LINKSITE supposedly links to and all of these urls are of type mysite.com/extended-reviews/product_comment/add/id/**/ where ** is an id number.
I click and drill down further into one of these Top Target Pages and I get the list of Linking Page / Target URL - this is where it gets strange. Every single link reported is in the form of : Linking Page = LINKSITE.com/category/productname Target UR= LINKSITE.com//extended-reviews/product_comment/add/id/**/ and is NOT linked to MYSITE at all.
Checking the source code of the Linking Page on LINKSITE , does not show any link to my site at all and going to the reported Target URL on LINKSITE every page go to a very basic comment form that is not displayed in a form meant for human visitors and is like :
{"content":"
\n
Post a comment<\/h6>\n
\n
\n
\n *<\/em>Nickname<\/label>\n
\n
\"\"
\n <\/div>\n <\/li>\n
\n *<\/em>Comment<\/label>\n
\n
The source code of this is again not showing any links to my site at all.
So as far as I can see there is no actual links between LINKSITE and mysite yet google is somehow seeing that there are because of us using the same theme and have the same reviews extension that creates the same url structure for comment submits.
Im completely lost as to why this would be and the only action I can thin of is to disavow the site but if google can mess up like this then Im scared that it will mess up again and some how disavow my site from my self or something crazy like that!
