Do search engines, Google in particular, need access to my wp-admin area? They demoted me from 5 stars for SEO to 2 stars because they cannot access that area. If they need access, how do I allow it? I use Yoast. Thanks for your help.
I thought he meant, is the googlebot blocked from that specific directory. But it shouldn't make any difference, because if the robots.txt block is correctly worded-- which it obviously is-- then search engines will never ask for the page in the first place.
What worries me more is why they're asking for pages in this directory. Surely you don't have visible links to private content?
Oh, I just remembered something - after the issue of the responsive version of WP, when auto-updates started, I saw a similar weird note in the AdSense UI - Seems they wanted to access wp-admin/css/colors/*.scss. Because this "error" is not due to Googlebot or any search engines, but an evaluation process within AdSense, it really isn't controlled in robots.txt or GWT.
I'm not saying that is the issue for the OP, but given that this is about Stars in the AdSense interface it could be. They seem to place a good deal of importance on responsive issues. To see what specific files they want to look at in wp-admin, all you need to do is click on the warning. The problem is not related to search engines or crawling, only to pleasing the responsiveness checking component of AdSense.
