I've read that interlinking your different clients on the same sites leaves a huge footprint and should be avoided. My question is how can you avoid overlap?
Let's say you have 5 clients, they are in the same niche.
You link together:
This is the only combination of linking you could do without overlapping. You can never link any of these 5 clients together again?
By this same math if you have 5 clients you can only build 10 sites before you get overlap? Then it seems the only solution is for each client to get their own site after the 10, to use for linking. Right? How do you expand past 10 sites?
What happens if you link client A,B,C on the same site? Does that mean you can never link any of those 3 together again?
