Ask Andrei: One of the world’s foremost search scientists takes questions

Over at the Yahoo! Search Blog, there’s a nice opportunity to submit some questions about search technology to one of the giants in the field, Dr. Andrei Broder, who recently joined Yahoo!

Dr. Broder is the co-inventor of many interesting Patents on search. The latest include one with Google’s Krishna Bharat on how to estimate the coverage of web search engines, and a somewhat different approach for ranking web page search results.

It was tempting to ask Dr. Broder which search engine he would estimate covers more of the web than others, but I instead asked about the Yahoo! patent I mentioned a couple of days ago, and where he might see the future of search headed.

Yahoo Acquisitions – The Middle Years

This is the third post in a series about the companies that Yahoo! has purchased.

I started with a look at the most recent with Yahoo! Acquisitions since Overture. Sometime after I made that post, we discovered that Yahoo! had also acquired a company named Webjay during 2005.

My second post looked at Early Yahoo! Acquisitions (the 1990s). While looking for those, I was amazed by the very large number of companies that Yahoo! partnered with for one reason or another.

This post includes some of Yahoo!’s acquisitions which probably have had the biggest impact on the search results and the advertisements that Yahoo! serves.

Google’s most popular and least popular top level domains

What are the most popular top level domains, or at least, which are the ones that show up most on pages indexed in Google?

I wondered this yesterday after seeing a news article stating that the registration of .cn (china) top level domain names topped 1 million for the first time ever by the end of 2005. The seed for my wonderment was probably planted when EGOL, at Cre8asite Forums, asked about using a .info top level domain earlier that day.

So I decided to check to see which were the most popular top level domains in Google, since that was the easiest place to get some statistics.

I found a couple of lists of top level domains (generic tlds and country code tlds), and searched for the number of results that appeared in Google, using the advanced “site” search operator and my tld lists. For example, a search for “” without the quotation marks might show me approximately how many pages appear in Google’s index that are on sites using a “.com” top level domain.

Around the web

Some sites and stories I’ve seen recently that I wanted to share.

I’m a big fan of RSS feeds, and think that they give many sites a chance to have a much larger readership than they would otherwise. How widespread has the use of syndication through RSS feeds grown? Ravenews takes a look at the use of RSS last year in RSS Year in Review. (via Dana VanDen Heuval)

Over the last few years, it’s become increasingly clear that Dr. Jakob Nielsen knows at least as much about marketing himself as he does about usability, if not more. I’m not sure that there are too many other people online who can attract as much attention with an article as he can, and he’s done a good job of doing so with his latest, Search Engines as Leeches on the Web.

I’m finding it difficult to agree with some of his opinions, and this is an opinion piece without any usability of scientific backing behind it, but I do agree that it isn’t a good idea to rely solely on search engines, and their paid and organic listings. Danny Sullivan has a very nice response to a number of the issues that Dr. Nielsen raises at: Search Engines As Leeches, The Difference Between Paid & Free Listings & Keyword Price Rises.

Some new Microsoft patent applications

Some new Microsoft patent applications about the web, and indexing pages, from last week.

Keep in mind that these are just patent applications, and have not been granted as patents. They may be avenues of approaches that aren’t developed in the future, or may be the direction that Microsoft takes. They might be challenged by claims of prior art, or may be unique approaches to processes that may improve the way we find information on the web.

Regardless, they are all interesting as pieces of insight into how one search provider might address search in the future.
