Is it a good practice to link from each link/article of the 2nd tier to multiple tier1 links?
Will that leave any footprints?

if you have 100 tier 1, and you have 200 tier 2, you might be ok to link to few tier 1 from the same tier 2. maybe 1%. rest should not be like this. if you can do not even do it. you are leaving a footprint
