Warning – 21st November 2019: The
max-image-preview:none attribute will now cause your pages to be deindexed regardless of other directives used. We advise not setting this directive to
none until further notice.
We found that when using the robots directive
max-image-preview:none in combination with
nofollow, Google Search will render the robots meta contents as such:
<meta name="robots" content="none" />
none is equivalent to
noindex,nofollow, and that means your page will be removed from Google Search, which is not our intention. The cause of this issue is probably due to a regex bug in Google’s parser. We informed Google via Twitter, but it went unnoticed.
So, from The SEO Framework v4.0.3, when you apply
nofollow to any page, the
max-image-preview:none directive will be purged from it. This change will prevent your pages getting taken off from Google Search unintentionally.
