In Google Webmastertools in the Instant Previews section of labs:
Do these images look different?
There are several reasons why your batch Instant Preview may look different from your on-demand Instant Preview. robots.txt restrictions and fetch failures are a common cause. (To get a complete report of what Googlebot was able to fetch from this page, use Fetch as Googlebot.) |

The three images above that text are labelled:
*On-Demand Desktop Search Instant Preview
*Mobile Search Instant Preview
*Pre-render Desktop Search Instant Preview
So, which one of the last two is the "batch Instant Preview" image?

Desktop Search. I tried a page that's completely roboted-out. On-Demand and Mobile Search came through loud and clear; Desktop Search is missing.
IP 209.85.224.80-99 (random)
UA for both: Mozilla/5.0 (X11; U; Linux x86_64; en-US) AppleWebKit/534.51 (KHTML, like Gecko) Chrome/12.0.742 Safari/534.51
referer for both: none for html, otherwise same as human
fetch order: html, css, js first, followed by all images
One copy of the page html. One copy of the shared stylesheet (accessible to all robots). Single copies of two (apparently random) images. Two copies of everything else including matching 403's on piwik.js.
If I saw this in logs I would never know it wasn't human, except for the missing favicon (only mobiles and repeaters skip it in real life).

I groked that the Apple Webkit UA was the preview process a few months back. I was sure that Google employees weren't so interested in the site as to be looking at it multiple times per day. :) Mine has trouble fetching css and js files.
It must confuse a lot of people that the words in the text don't match up with the image headings. Not the most clear instructions I have seen in a while.

In real life, the on-demand preview looks like this:
Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/534.51 (KHTML, like Gecko; Google Web Preview) Chrome/12.0.742 Safari/534.51

At least it's more honest than when they first introduced Preview. You may remember they showed two versions: "what you see" vs. "what Preview shows". Except that "what you see" was really the Previewbot, while "what Preview sees" was really the googlebot. You could tell because "Preview" (i.e. the googlebot) couldn't get to roboted-out directories. Now at least there's some hint that the previewbot doesn't mess about with robots.txt.
