Hi I've read a lot of information regarding the optimal anchor text ratio that should be applied in regards to money making keywords, naked URLs, etc. in order to stay safe from penalties but I have a question that I couldn't find the explanation for. Does this ratio only take into account Tier 1 links or can you level out the % with the Tier 2s and Tier 3s? Say my money making keyword is "Buy XXX" and I want to keep that exact match link at 1% of all anchor texts. Say I then build 10 Tier 1s and 100 Tier 2s. If all my 10 Tier 1 links have "Buy XXX" as anchor text and none of my Tier 2s do, does that give it a 100% ratio for exact match anchors or 10%? Are the Tier 2s taken into account when you calculate the ratio?
