We have several large Ecommerce sites with hundreds of links on each page. I have been trying to think of ways to focus our internal linking to increase certain pages relevancy. My thought was to put nofollow in the main navigation (since there are hundreds of links there controlled by dropdowns) and only follow the links on each page for the products we are selling and promoting (15-20 links). I would still be using a sitemap that includes the links. Is this a terrible idea? if a link is nofollowed in the main navigation does that still count as the one mention for google if it points to the same page that a normal link points too that is in the content of the page? since all of the main navigation is the same on every page of the website would it be good to only put nofollow on the subpages/subsections and leave the home page navigation alone (that would allow the spiders to crawl all of those links on the home page but not crawl those same links on the subsections where I could then focus the linking).

Hello I am looking for a tool to help me to submit websites in directories, something like the yooda tool. http://www.yooda.com/outils_referencement/submit_center_yooda/ This tool seems good no? do you offer something similar at seomoz? or where could I find some similar tools and in which languages is it available?

Hi Guys I'm not sure which section this one belongs in as I didn't see a section for domains/tlds. I wanted an opinion on the future of .co domains. We own a gift company (www.xperiencedays.com), as well as a gift recommendation site (www.uniquegifts.net), and invested in a few gift occasion .co domains (www.birthdaygifts.co, christmasgifts.co etc). This was partly because they were cheap and easy to come by, but also with a hope that they soon gain some public recognition. My question therefore is whether anyone within SEOMOZ has an opinion on whether .co will be widely accepted, whether they will (as google claims) be treated as a non-country specific url, and early success stories you know of, and finally whether the recent news from Overstock to rebrand as O.co (http://www.overstock.com/guides/faqs-about-o-co) is the kick start that .co need. I realize that is more than one question
