Google Instant Search Released

Google has done a lot of research to show that speed matters quite a lot to users. When results appear in less than 250ms the user is much more satisfied than even 500ms. Anything less than a quarter of a second is thought of as "instantaneous" and the user starts thinking of it very differently.

Here, they are taking it down to less than 100ms, which is now operating faster than the user can even perceive (for that matter, it's faster than many users can type). So the real effect is that they have now eliminated the need to click on "Search". So now Google is even more interwoven into your thought processes, and other search engines are going to seem unbearably slow pretty soon.

The "micro-sites" you are talking about, and the long-tail SEO people are complaining about, are nothing new at all. It's been common for SEOs to build and rank sites like that for at least 5+ years.

The difference is Google made a big change to it's search algo back in April and in my opinion it was for the worse.

It actually ranked bigger sites (bigger than micro-sites but not necessarily the biggest ones) higher for less relevant long tail searches, presumably to weed out the micro-sites.

So the difference between now and 2 years ago is you are getting a less relevant result list, not that you are getting an SEOd micro-site.

I have a medium-sized website which relies mostly on long tail SE traffic,

Contrary to what many are posting here about this hurting sites that rely on long tail-- my traffic is above normal today. I'm not seeing a decline due to this search change.

I also would not see it in Google's interest to have less long tail searches, since those tend to earn it more money.

Except that live search was already something that was happening on lots of sites back then. By now it's hard to see that instant searching is even novel, much less a ripoff of any other interface.

Google putting their completion together with their instant search (an opportunity not available to API users, of course) is pretty neat, though.

For example: user starts typing a long tail keyword search and an unrelated result is displayed. Even though the user was not looking for that specific keyword combination, he will see the results (and the ads) for that keyword.

Google has made it very slick, although they at least have a fallback: "oops, Google Instant won't work on this browser (cough, IE) so here's Google Brewed." If you bill your service as instant search, you need to work with even lame browsers.
