Nice going bonustreak..
I think (personally – maybe right or wrong) that it would be best to also rid your page(s) of linkes to grandpriveaffiliates.com as otherwise it just increases their ‘importance’ on google..
I *think* posting the name of the domain (but not linking) would be preferable – then the page would be found in searches of the domain but not considered as one ‘linking to’ it ..
Also, I wouldn’t leave the other stuff about the casino, personally (i.e. all the ‘hyping up’ stuff from previous old stuff) although of course I think this may help the page to be found when searches for the casino are made. Tricky one lol..
Not sure if any ‘SEO expert’ can suggest whether or not the leaving links to them is a good or bad thing based on the purpose of ‘downgrading’ their site on search engines etc..? Any suggestions there would be much appreciated. (I’ve removed ALL links out to them and their domains for now)
I’m also pretty sure already also that they will be leaving the casinos operating, AND the ‘old’ affiliate links will still track to the casino.
Even if they did decide to turn this around now (LOL probably with an explanation of some disgruntled now ‘ex’ employee sending out the email lmaooo) then I have lost far too much faith in these guys and their future intentions and respect for affiliates.
Also, of course happy to link across other black-listing pages with others so long as it’s at least 2-way
