No snippet meta tag
The no snippet meta tag is a tag designed to keep Google from using page text in the SERPs, beneath your title tag. The use of the no-snippet meta will remove the instant preview. If currently using the no-snippet tag, is it time to consider removing it in order to test the benefit of displaying an instant preview?
I do not use the "no snippet" meta tag. Nor do I block any bots (good or bad) but my site does not show a preview for some reason. Bummer.
