I manage a collection of 3 travel websites with DA's in 50's and 60's and have launched a new site which currently has a DA of 35.
Currently there are no links between sites in the footer. Adding a footer link to new site from the existing stronger sites will be relevant to users on those sites.
How would Google treat such footer links - we would be talking about a link from 5000+ pages from 3 sites?
Would it help us on the new site? Damage the new site?
Could it impact negatively on the currently strong websites?
Thanks
