I don't "nofollow" affiliate links but I have quite a few. Doing them one by one would just be an impossible job. Would it be best to get a plugin that nofollows EVERYTHING? What would google prefer? I need to DOFOLLOW some links because those sites deserve it.

I am using Yoast Wordpress SEO and I have clicked on the option to deindex archive subpages. However, I have over 200 duplicate title tag errors in Google Webmasters and most are due to subpages. I am using the URL removal tool but I am going to create several pages every day which is just going to cause more duplicate title tag errors. I don't understand why the Wordpress SEO settings are not working. How can I get google to stop indexing archive subpages? My site tanked BIG TIME about a week ago. Every day it is worse. From 320 clicks a day to 30. Any help would be appreciated.

I have parent categories and subcategories. Will it be harder for the subcategories to rank well because they have a parent category? The URL is longer, for one. I am just wondering if I should not have parent categories. I have one category page doing really well and I am trying to boost the others (most of which are subcategories) and this is a concern for me. Thanks! Edit: I also have a category that has 2 parent categories. I want it automatically in those 2 categories and one of its own. By itself it is very important keyword. Is this ok or should I have it be a parent category?
