On http://moz.com/help/pro/rogerbot-crawler Moz gives an answer to the question "We are still seeing duplicate content on Moz even though we have marked those pages as "noindex, follow. Any idea why?

Moz is not a search engine index, it uses a crawler. If those pages are not blocked by the robots.txt file, then Moz will crawl them. They ignore the noindex tag because they don't index anything. Search engines will honor the noindex tag and not index a page if you specify with the robots meta tag. However, to remove pages from the crawl, disallow them in the robots.txt or metarobots.

Their answer is not exactly clear, but according to it, no, a meta noindex  will not block rogerbot from crawling your page.

Hi Daniel,

You're welcome to PM me with your questions.

There may be slightly more reason to lean towards using subdirectories but each case is different.  Have you looked these over yet:

• International SEO: Where to Host and How to Target - Whiteboard Friday - Moz
• content posted under different TLDs a problem? - YouTube

Zoran,

Looks like you picked up a copy of the 1996's Backpackers Guide to Linkbuilding.  As Ricky said, that stuff's not worth much today.  Basically, the more control you have over a link today, the less it is worth--with bookmarks being at the low end of the scale and editorial links from authoritative resources on the other end.  Rather than spending your time at the low end, work on building out your social media profiles and figuring out who your audience is so you can publsh content for them and announce that content through your social channels.

Mayank,

If, when you type in the URLs and the server give a response of 404 (page not found) then they will eventually drop out of the index.  You may also use your Google Webmater Tools Remove URL  tool (under the "Google Index" link) to request removal of the URLS.
