I just took a look at Google's Instant Preview and I'm impressed. Works on Chrome here, but not IE8. I'm wondering about the SEO impact of this new feature. It seems to me that with Instant Preview, your home page really needs to be visually appealing - moreso than previously.

Also noticed it doesn't work on Google ads.

Yeah, I've liked the preview from when they announced it. When I search for things it can quickly show me a preview of the page and I can scan for junk ads etc before loading up the page. it can be a little slow at times as it has to render the preview, but overall, I like it. Like yourself, I'd like to see it on the Ads too

At first I didn't think I would like it, but after using it for a little while now, I do.

Better than Instant Search

I think so! But I'm not sure whether the preview is a good idea... probably it is because it makes people to feel more confident about clicking on any SERP.

At the same time many websites would loose clicks, just because the users did not liked what they saw in the preview!

I don't see much use from instant preview. While I don't mind it, most websites nowadays load fast enough and the instant preview does not really allow you to read any of the information anyway, so you end up loading the page...

The ONLY benefit I see is knowing whether you are about to click on a site full of ads and MFA content (if you can tell) or a quality resource you are looking for.

I'm with Art on this one. I find it to be of little actual use. It has a "neat factor", but it soon wears off.

Well, Chrome is good.. and I think it's bcz chrome most faster than IE8

I think if I were using the preview, my attention would be captured moreso by a visually appealling page rather than one composed entirely with text (even if I couldn't read what was on the page via the preview), getting those pages a better chance to be clicked through to.

I think its usefulness lies within the preview itself, more in that it highlights the text that it attributes to the query you entered. Thus resulting in a quick method by which you can determine the quality of the page before firing it off into perhaps a new tab, or avoiding the continual back/forward clicking involved with searching.

Personally that is the only benefit currently see, as mice and various other software fill in the other gaps involved with searching, such as Logitech's setpoint software which allows users to highlight text within any application and simply press a button to preload and launch their choice of browser and search provides results - which essentially is the same purpose of the preview
