AltaVista

AltaVista is gone, and has been since 2013

AltaVista is not a search engine you can use. Yahoo announced its closure on 28 June 2013 and shut it down on 8 July 2013, pointing the domain at Yahoo Search. There is no AltaVista index, no AltaVista crawler, and no AltaVista result set anywhere on the web today. That is what the Discontinued verdict at the top of this page means, and it is not a soft judgement about a service in decline — the product does not exist.

The closure was less dramatic than it sounds, because by 2013 AltaVista had already stopped being an independent engine. After Overture bought it in February 2003 and Yahoo bought Overture that October, AltaVista's own index was retired and the site displayed Yahoo's results behind AltaVista branding. The 2013 shutdown closed a front-end. The engine underneath it had been switched off years earlier — exactly when is not documented in any primary source we could locate, so this page does not put a date on it.

This matters for anyone compiling a list of Google alternatives. AltaVista appears on a surprising number of such lists, usually because the writer typed the address, watched the browser load a working search box, and assumed the service was alive. It is not. What loads is Yahoo.

Why altavista.com still seems to work

Checked on 19 August 2026, altavista.com returns an HTTP 302 redirect to search.yahoo.com/?fr=altavista. The redirect Yahoo installed in 2013 is still running thirteen years later, and the fr=altavista referral parameter is still attached, so Yahoo is still counting the traffic that arrives from the old brand.

Three things are worth separating here, because conflating them is the single most common error about AltaVista:

• The domain resolves. Someone still renews it and a web server still answers on it.
• The redirect works. You land on a functioning search page and get results for your query.
• The engine does not exist. Those results are Yahoo's — and Yahoo has no crawler of its own either. Yahoo's web results come from Microsoft Bing under a long-running syndication arrangement.

So typing altavista.com in 2026 puts three brand names between you and one index, and none of the three is AltaVista's. A domain that resolves is not a search engine that works. If a page tells you AltaVista is still operating, that page is describing a redirect.

How it worked: Scooter, and an index that held the whole page

AltaVista's technical achievement was not its ranking. It was its crawler and the size of the index (the engine's own stored copy of the web) that the crawler could fill.

The crawler was called Scooter and was written by Louis Monier at Digital Equipment Corporation's Western Research Laboratory in Palo Alto. Its distinguishing property was concurrency: Scooter was multi-threaded, keeping large numbers of HTTP fetches in flight at once instead of requesting one page, waiting, and requesting the next. That is a mundane-sounding design decision with an enormous consequence — it let one team build an index an order of magnitude larger than its contemporaries could. This characterisation is well established in the secondary literature rather than drawn from a surviving DEC technical report, and the specific concurrent-connection figures that circulate online are unverified, so no number appears here.

The indexer, built substantially by Michael Burrows, stored the full text of every page rather than titles, keywords and metadata alone. Predecessors indexed descriptions of documents; AltaVista indexed the documents. Query handling was weighted Boolean, with basic and advanced modes, and later natural-language queries. From December 1997 it also hosted Babel Fish, a free machine-translation service built on Systran and one of the first of its kind on the web.

What AltaVista never had was link-graph ranking. It scored pages on the words in them. Google's PageRank scored pages on which other pages pointed at them, and on a web that was rapidly filling with keyword-stuffed junk, that difference decided the market. Anyone who says AltaVista's innovation was its algorithm has the story backwards: the algorithm was its weakness.

There is a neat irony in its origins. AltaVista was conceived by Paul Flaherty at DEC as a demonstration of the company's 64-bit AlphaServer hardware, which had enough memory to hold a web-scale index in RAM. The most important search engine of the mid-1990s began life as a hardware marketing exercise.

Who owned it, in order

The ownership chain explains most of what happened to the product:

1. Digital Equipment Corporation (1995–1998) — built it, launched it on 15 December 1995 at altavista.digital.com, treated it as a showcase rather than a business.
2. Compaq (from June 1998) — inherited AltaVista by acquiring DEC, and bought the altavista.com domain from an unrelated software firm, AltaVista Technology Incorporated. The purchase price is widely reported as US$3.3 million; that figure is repeated everywhere and primary-sourced nowhere, so treat it as reported rather than confirmed.
3. CMGI (majority stake, June 1999) — filed for an IPO that was abandoned when the dot-com market collapsed, and rebuilt the site as a portal.
4. Overture Services (February 2003) — acquired it for approximately US$140 million in cash and stock.
5. Yahoo (October 2003) — acquired Overture and with it AltaVista, in the same year it acquired Inktomi. Yahoo has held the domain since; Yahoo itself has been owned by Apollo Global Management since September 2021.

Note who is not on that list: Google. Google has never owned AltaVista, never bought its index, and never acquired any part of it.

How it made money, and how big it got

AltaVista was free to use and funded by advertising: banner display and sponsorship at first, later supplemented by paid-placement and paid-inclusion listings once Overture, a company built on paid search, owned it. There was also a licensing business, AltaVista Search Intranet, which sold the engine to companies for searching their internal networks.

The strategic error is easy to identify with hindsight and was visible at the time. Under CMGI between 1999 and 2002 AltaVista was reworked into a general-purpose portal — email, shopping, a directory, news — chasing Yahoo's advertising model, because portals were what the market rewarded. It did this in precisely the years when relevance ranking became the competitive battleground. A company with the best crawler on the web spent the PageRank era redesigning its home page. Search quality and focus declined; Google's did not.

The audience numbers, with the caveat they need

No modern-methodology market-share series covers AltaVista's peak. StatCounter did not exist in the relevant period and no comparable audited panel data survives, so any figure claiming AltaVista's "market share" in the 1990s should be treated with suspicion. The numbers that do exist are reported claims, mostly compiled from contemporaneous press:

• 15 December 1995: around 300,000 hits on the first day.
• Late 1997: more than 80 million hits per day.
• 1997: approximately US$50 million in sponsorship revenue.
• 1998 and 2000: ranked the eleventh most-visited website.
• 2000: used by 17.7% of internet users.
• February 1998: 45% of professional researchers named it their preferred engine.

The last of those is the most telling. Among people whose job was finding things, AltaVista was the default choice barely five years before it was sold for scrap value relative to its peak. Search markets move faster than brand loyalty does.

Common misconceptions

"AltaVista was the first search engine." It was not. WebCrawler in 1994, Lycos in 1994 and Infoseek in 1994–95 all preceded it. Its genuine claim is narrower and more interesting: the first fast, full-text, web-scale index behind a simple public search box.

"AltaVista was a Silicon Valley startup." No. It was an internal research project at Digital Equipment Corporation, a Massachusetts minicomputer maker, developed at DEC's Palo Alto laboratories to sell AlphaServer hardware. It had no founding-startup structure, no venture round, and no independent existence until it was already an established product.

"Google bought AltaVista." Google never owned it. DEC, then Compaq, then CMGI, then Overture, then Yahoo.

"AltaVista still works." The domain answers; the engine does not. See the 302 redirect described above, verified on 19 August 2026.

"Yahoo killed a working engine in 2013." Yahoo closed a front-end that had been showing Yahoo's own results for years. The independent engine died quietly, well before the announcement, and the obituaries in July 2013 were for the brand.

What AltaVista is good for now

As a live tool: nothing. There is no version of AltaVista that returns AltaVista results, no archived index that can be queried, and no successor product carrying the technology forward. A reader looking for an engine that is not Google gains nothing here — the redirect delivers Yahoo, and Yahoo's web results come from Microsoft Bing, so the destination is one of the two large Western indexes rather than an alternative to them.

As history, it is genuinely important, and the useful lesson is structural rather than nostalgic. AltaVista proved that indexing the entire text of the entire web was tractable, two and a half years before Google launched, and it lost anyway — because indexing everything and ranking it well are separate problems, and the second one turned out to be the business. Every engine covered on this site is still working on that distinction.
