Hi, so I have about 90 geobased websites for franchise business. I have all sites on the same server, but no interlinking to main corporate site which is on same VPS WHM server, however that domain has a unique IP address, different C class and all.
So my question is, if I placed a link to on ABOUT US page for all 90 sites that point to main corporate website, will google see that as me trying to use a PBN, especially when all 90 sites have same IP? There is no blogging, they are all static sites and I wouldnt dare to do footer link or sitewide link.
