Google's Weakness, AltaVista's Strength
Some people love the results they get at Google, others are often disappointed. To a large extent, both the pluses and the minuses derive from Google's ranking system, which (as the folks at Google explain www.google.com/technology) depends largely on the number links to a particular page and the relevance of the content on those linking pages to the content on the target page, and the quality of the pages doing the linking.
Thanks to that complex and brilliant system, over time, the best pages often rise to the top of search lists. But that takes time -- a lot of time.
It works great for old, established sites to which many other old, established sites have linked. (It works great for my site :-) www.samizdat.com ). But new sites, regardless of the quality of their content, get short shrift. It takes 2-3 months for the new pages to get into the Google index. Then it takes time -- perhaps years -- for other "important" sites to discover the new site and link to it; and then months more for the new versions of those pages with those new links to get into the Google index.
So if I'm looking for content that is likely to have been on the Internet for a year or more, Google is great. But if I'm looking for fresh content, I'll go elsewhere.
For me, for years "elsewhere" meant AltaVista -- for two reasons. AltaVista used to add new pages to its index, for free, within two days of submission, while other search engines typically took weeks or even months. That meant they had the freshest content. In addition, AltaVista provided you with a set of very precise commands that couldn't be matched anywhere else.
Over the last year, as AltaVista has struggled to become profitable, they have destroyed their beautiful free submission process, trying to force Web sites to pay for submission. Free submissions (which typically come from the kinds of content-rich sites that I'm interested in) now seem to take three months or more -- no better than the other search engines and often worse.
Fortunately, the powerful commands remain -- for instance, the ability to exclude as well as include terms in your query. AltaVista lets you use minus signs and plus signs to indicate what you really don't want and what you do want. And for some specialized searches the exclusion is essential.
For instance, say you want to know what Web pages outside of your own site have links to your pages. At Google, I can do a search for link:samizdat.com or get the same results by going to their "Advanced" search and using their "page specific search" to find pages that link to a particular page. But my results are then littered with pages from my own site -- information I don't need and don't want. At AltaVista, I can search for +link:samizdat.com -host:samizdat.com and get exactly what I want -- finding out who thinks enough of my pages to have linked to me without my having contacted them: a valuable list of well-wishers and potential partners.
Similarly, Google lets me restrict a search to a particular Web site. For instance, if I include in my query the term site:samizdat.com or in Advanced search under Domains I choose to restrict the search to that domain, Yes, I get results only from that site. But to use that command, I need to have additional query terms: site:samizdat.com alone generates no results.
At AltaVista, however, I can search for host:samizdat.com and get a complete list of all the pages at my site that are in the AltaVista index. Or I can search for url:samizdat.com/isyn and get a list of all the pages in that directory at my site are in the AltaVista index. Or I can search for url:samizdat.com/consult.html to see if that particular page is in the index.
In other words, AltaVista provides a higher level of precision and the ability to get information that is particularly valuable to people in charge of Web sites and Web-based marketing projects. And if they'd just fix their free submission process and provide the service they used to, they'd kick Google's ass for searches for current information.
P.S. -- The folks at Google are very proud that their system defies human tampering. In fact, what they've done is encouraged the development of bizarre business models structured to take advantage of their link-based ranking system. For instance, Webseed Publishing now has over 1000 sites, all with different domain names. These content-rich sites are each run by different dedicated individuals. (I'm one of them :-) In many cases, the content deserves high rankings for its quality. You might wonder why the umbrella business for all these sites bothers to maintain over a thousand different domain names, when it would be far simpler and cheaper to have them as directories under a single domain. But because the domains are different, the many thousands of links these sites have to one another all count toward the automated calculation of their popularity and quality at Google, giving them all a boost in the rankings and hence bringing Webseed more traffic and hence more revenue.
P.P.S. -- AltaVista appears to be making a comeback. Six years ago, when I was in the Internet Business Group at Digital and Digital owned AltaVista, about a third of the traffic to my Web site came by way of AltaVista. Whenever AltaVista had a glitch, I saw it immediately in my traffic stats. In fact, I sometimes was able to alert the engineers at AltaVista about problems before they had noticed them themselves. Over the years, due to increased competition from other search engines and also due to the business folks at AltaVista making bad decisions and jettisoning great capabilities/services (like 2-day free submissions, their affiliate program, LiveTopics, and newsgroup search), the number of people finding my pages by way of AltaVista plummeted. By January 2002, only 1% of my traffic was coming by way of AltaVista, despite the fact that as a long-standing fan and also as co-author of the book The AltaVista Search Revolution, I had lots of information about AltaVista at my site. I was actually getting twice as much traffic from the International Atomic Energy Agency (part of the UN), when I had no information at all related to atomic energy. But in recent weeks the traffic from AltaVista has climbed sharply. It now amounts to 6% of my total. I wish I knew why that was happening. In any case, I hope that trend continues.
Whenever Google results have been disappointing, I hop over to AltaVista and search there.
For me, Google doesn't have to be the perfect search engine - it's already enough. I type in google.com and it loads damn near instantly. There's no annoying advertisements, and I can search in h4x0r or Sveedish Chef, bork bork bork.
If I can't find what I want on Google, fine, I'll use another engine. And what's wrong with that? We honestly can't have too many search engines (Well, business problems aside), because each one ends up with different ranking systems, different data pulled up from queries, etc.
.. are you suggesting that different goals require different tools, possibly made by different companies? Don't let the OS market know this, or we will kill the thriving flamebait OS war scene. :(
Actually, there is lots of good information you provide on the capabilities of search engines. I, for one, would love to see more "A is good for this, B is good for this", instead of simply grouping and competing A & B, suggesting that one can only use one.
IMHO, this is where (free) web services really rule - I can't buy 5 different cars for 5 different reasons I use cars, but in the case of these types of services, the cost of using and switching between these services is very next-to-nil. Hopefully, web services will start encouraging companies to share again, as Google and Altavista may very well demonstrate that sharing market segments with other players makes everyone happier in the long run.
"Old man yells at systemd"
Now it took months to get into DMOZ, but we did. Yahoo - still hasn't accepted us into our proepr catagory even after 2 or 3 tries over a year and a half.
I think Google could benefit by adding some more advanced filtering command slike Altavista has - I agree they are nice. But the bottom line is, for obscure sites, once you get in Google, look out. Months later we finally got into the other mainstream search indexes (we submitted to them all at the same time) and in teh end Google is THE place for referrals. By orders of magnitude. YMMV, but it seems the other search indexes blew it when tehy killed free submits since folks knwo that they will only return paid sites (plus rank skewring, for $$$, etc)
Only time will tell, but I use Google daily and am happy with the results and performance - no other search engine comes close IMHO
Top Most Bizarre/Disturbing Error Messages
i wish more sites would develop tool bars similar to google... it is extremely convienient.
on all my windows boxes it is one of the first things i install.
google is probably the best search tool right now, and they make using it a breeze. altavista used to be the best search tool, but they made it harder and harder to use, and then search tool lost its top spot. totally different situation. if google looses its top spot in the search tool field, i'll still use it for its ease of use.

Perhaps AltaVista is indeed better (or used to be, as the author points out) at indexing new content, but I'd never know, as I have been using Google exclusively almost since its public debut. However, I think that this point will become less and less important.
Yes, it's true that Google's algorithm prevents new content from being ranked high, because no one has linked to it yet necessarily, but that's by design - it is indeed at that point unproven in terms of quality. However, the spidering process can use improvement so that when many many people link to this new site just a few days later, it now ranks higher.
Google specifically mentions (in previous interviews I read with employees) that they're always working on updating the speed, as well as the precision. The longterm goal is to significantly decrease the amount of time it takes to respider everything, and therefore make the info more relevant faster. I trust that they will continue to improve, and eventually this differentiation between "Altavista is better for new stuff, Google for old" will go away completely.

Google has exclusions, site and link queries too.

I'm a librarian. It is the most difficult time in history to do library research. There are hundreds of overlapping commercial databases out there, each with their own coverage, interface, and search engines.
Students used to locating information with Google are appalled at the steps it takes to locate a scholarly journal. You need to browse a list of subject databases, search them, then locate a printed copy of the journal via our catalog (a growing but still small percent of journals are available online).
Someday searching the various literary databases may be as easy as Google, but in the meantime there are drastic capitalist impediments to making it easy to do library research.

...but you can also make Google pop up when you click the "Search" button in IE. This makes Google searching even easier since you can have the search window open on the left and hit your search results on the right. (Yay for "tabbed browsing", IE style.)
Also, the coolest feature of the Google toolbar IMHO is not even the instant search, but the "Highlight" button. Gone forever is hitting Ctrl-F and typing in a search term. Just search for something in Google, go to a result, and hit "Highlight" -- the search terms are instantly highlighted. This saves me an incredible amount of time when I'm searching through, say, mailing list archives.
The Google toolbar is one of the biggest reasons I use IE. (Well, that and the fact that page developers, including myself, follow the rule of thumb "Design so that it looks good in IE and works in Netscape.") But anyway, I digress. If you're using IE, check out toolbar.google.com and download it.

Similarly, Google lets me restrict a search to a particular Web site. For instance, if I include in my query the term site:samizdat.com or in Advanced search under Domains I choose to restrict the search to that domain, Yes, I get results only from that site. But to use that command, I need to have additional query terms: site:samizdat.com alone generates no results.
You can use the following workaround to do a site: search on google without any keywords. Just do "site:yoursite.com -stuff" where stuff is gibberish (bang on the keyboard a bit). For example, this search shows 1,290 pages from samizsat.com. On the other hand, an altavista search for that site shows 1,090 hits for pages on that site.
I don't know why Google doesn't allow simultaneous "site:" and "link:" searching, as that is something many users would like to do.
Alas, they can no longer be reached. Their search engine is seriously broken. It picks on a site and hits it hard and repeatedly.
They will make 100,000 requests on a site with only 20,000 static items within 24 hours. On our co-operative co-loacted server, we host around 80 sites, many of which are content rich. When Alta Vista choose to visit just one of them, our total bandwidth usage jumps by an order of magnitude.
We have been unable to get past their front line support, I am not prepared to maintain robots.txt on all of our member's sites just to control their broken robot, so we had no alternative but to block their entire subnet at our firewall.
If anyone has evidence that the AV robot is fixed, I'd be happy to let them back in.
Read the excellent information Google has provided about how the engine works, and use the engine with its inner-workings in mind. When you meet the machine half-way instead of trying to dumb it down for the user, you'll get a hell of a lot more done.
In Google's case, taking half a minute to think about what you're looking for, then tossing in a few related bits of jargon or other words relevant to the context you're after does amazing things. With a little forethought, you can almost always find what you're after and be down to a page with nothing but relevant links with just an extra word or two added as filters.
The author is basing this on outdated information. Google knows to crawl sites that change frequently more often than those that don't. Here is a concrete example:
I posted Two Kinds of Order by John Marks on March 11th, and mentioned this to some colleagues who might be interested. I linked to it from a Weblog or two,and Doc Searls did too.
Today it is number 1 on a search for 'two kinds of order' out of over 2 million, and a search for John Marks brings the page up in 5th position, despite there being lots of other John Marks's on the net.
Thats what I call fast (and relevant)
