Why is Google not following a 301 redirect on the robots.txt file?

[FRL]

Hi Guys,

I recently posted a question on the Google Webmasters Forum http://www.google.com/support/forum/p/Webmasters/thread?tid=683e71557db7fd54&hl=en&fid=683e71557db7fd540004a4b4add8cbb6 and didn't get a satisfactory feedback so I thought I will put this to the SEO gurus on here. Perhaps one of you guys might good buddies with Matt and might be able to ask him directly. I actually posted on Matt's blog but he hasn't got back to me.

Basically we did a URL restructure for client and set up 301 redirects and saw a huge drop in rankings over time. The 301 redirects seem to work fine and have been tested by many many people. We suspected that google might be ignoring the 301 redirects or devaluing them and so I reviewed the server log to see what is happening when the googlebot crawls the site and it showed that on many occasions the googlebot did not reload the page after hitting a 301 redirect.

Sure.. you might say it probably queues it or Google might just be checking that the 301 redirect is still in place but why check so often (with a few hours to a day on the same URL) it even skips a 301 redirect on the robots.txt file i.e. from http://clientsite.com/robots.txt to http://www.clientsite.com/robots.txt.  from non-www to www version.

I don't think it is easy to dismiss the skipping of the robots.txt file - this 301 redirect should be loaded immediately to use the instructions the gooblebot requires to crawl the page.

Any help will be appreciated. I can sent the server log to anyone personally but I am reluctant to post it on here.

Regards,

Zan

Thanks John, I check the robots.txt redirect and it is redirecting fine from the non-www version to the www version. I also know that G is crawling the site because we can see requests by G in the server log. Also as with the case with the other 301 redirects there were cases G followed the 301 redirect on the robots.txt file but also many cases where it didnt.
