Are the links into adsense blocks passing some Page Rank, Juice?

    Can you show proof that they are passing Page Rank, Juice?

    Your question was Adsense specifically - I linked to the robots.txt being used for Adsense, so that is blocking them.

    Google can however crawl and interpret some javascript. I can't tell you how complex they can currently evaluate.

    thus the best way to block them crawling javascipt is to have it in an external file... and block it with robots.txt

    They even have a special way they can now crawl AJAX.

    Ok, then by default all adsense groups are being readed and links followed if I don`t do anything like add the robots thing.

    It`s right?

    No - that robots.txt is on their domain where the javascript file is being read from, and where the redirects pass through, thus Googlebot which respects the REP (robots exclusion protocol) will not be able to access the javascript, and even if it could, will not be able to follow the links.

    That doesn't prevent other bots doing it

    Yeah, I know that, but what I try to say is:

    That means (If I didn`t have this robots.txt file) google will pass my PR on the adsense links?

    Well the effect on your PageRak is difficult to be specific

    The javascript is blocked by robots.txt on Google's servers
    http://pagead2.googlesyndication.com/robots.txt

    That technically creates a dangling/hanging node that in theory could accumulate Pagerank.

    This is the location of the javascript
    http://pagead2.googlesyndication.com/pagead/show_ads.js

    The only visible proof of what might be happening with Pagerank for that page (even a remote javascript is a page) is using Google's toolbar data, which returns a grey bar (unranked).

    It is quite possible that Google ignore javascript they know to be ads - it would make sense for them to do it, they have suggested that placing their ads on a site has no ranking benefit, but it is likely it also has no ranking penalty from leaks.

    If that javascript was to accumulate PageRank, there is no information on what happens with it other than 10 year old patents, and one mention of the "reset vector" by Matt Cutts a year ago.

      Thanks.
