Welcome to the Q&A Forum

IMO, if you had 100+ links into deeper pages the only time that i feel it would be appropriate is if you have 100+ main categories. If I were google and noticed that there were 100+ link on the homepage pointing to obvious pages which would be in a main category I would think that was a bit inappropriate. So yes I would go for <100 always unless I had 100+ categories. i.e. ebay, amazon, craiglists, gumtree would get away with this.

Sorry for the very late response, but wanted to let you know that I took a look into this and it appears that there is a bug in the ranking overview which makes it so we only shows the visit data for the first of two duplicates (differing only by capitalization) that is added. The first will show the number of visits and the second will display a value of "pending". As for the data itself, if you go to the ranking history for the 2 keywords, it should show the same historical visit data (and has in our tests), so this is consistent with how we should be displaying this. There is certainly no need to be tracking different capitalizations separately, as our GA data collection is not case sensitive. If you are still seeing something odd aside from the pending on the overview, please let me know. Thanks for catching this and bringing it to our attention! Adam
