Links in clients footers

[SeattleWebGuy]

I have one quick question. Maybe you can just point me to the correct post... We have currently been adding our own website link in the wp copyright footer of clients websites that we build and design.  We understand that this is not the best option for SEO since it might be punished by Google as spam. Can you please recommend a better solution for this? From an SEO standpoint is it best to just remove the links?  Make them nonfollow? Add it to a "Website Credits" page or "About Us" page.  I always discuss this link with all clients and offer a discount which 100% of them take in the end.  I just need to work on our ranking a bit now and see that this could be hurting things more than good.

I am not sure if you can secure this or not from your clients. However, I reckon to get link from their about us page or company overview page under the heading of IT team or technical team with a little brief along with one external link to your site.
