What does the blocking_google property in the CSV export mean, and what to do about it?

[EconostoNL]

The CSV export for Crawl Diagnostics contains a column named "blocked_google". It states a blocking date/time but doesn't occur on all our webpages, not even on all pages of the same type / structure.

There are no other flags on these records that would explain a blocking of Google; all other agents are not flagged, and our robots.txt doesn't contain any blocks either. The only flag the records have in common is "Page Title > 70 characters". Of course, I could just assume this is the reason for the "blocking_google", but is it?

What evaluation makes the crawler fill in this property, and how to handle/solve it's occurrence?

check that those pages don't have some like:

meta name="robots" content="NOINDEX,NOFOLLOW" />

in the source code

Thank you for your response.

Our CMS generates the following meta-tags on the affected pages:

Pragma is for cache control, content-type and google verification are clear. P: is Pinterest Social media, the rest is standard again. I searched the source of the page for "robots" as well, but no results.

can you give an example of one of the pages the is  "blocked_google"

Btw try screeming frog ( you can do 500 pages for free), it should pick up the same error and might explain why.

Thank you again for your response.

The following link forwards to one of the affected pages: http://bit.ly/1b3IVYB

that page seem fine, and it also indexed by google, so I'm not sure whats the story with that.  Might be best to contact seomoz support (help@moz.com I think)
