Question

Researchers investigating the history of online sweepstakes promotions often rely on archived versions of promotional websites preserved by a well-known nonprofit digital library that operates the Wayback Machine. This archive has, since the mid-1990s, received daily web crawl data donations from a commercial web analytics company founded in 1996. Identify this company and explain its data donation relationship with the nonprofit archive, including when the donations began, how the data are incorporated into the Wayback Machine, and the name and current public accessibility status of one specific crawl collection associated with these donations.

Answer length: 220-320 words.

Depth checklist

Alexa Internet + Identified as the web analytics company founded in 1996 that donates crawl data
Internet Archive + Identified as the nonprofit digital library that operates the Wayback Machine and receives the crawl data

Width checklist

States that Alexa Internet began donating crawl data starting in 1996
Explains that the donated crawl data flow in daily and are added to the Wayback Machine after an embargo period
Identifies the nonprofit recipient as the Internet Archive, operator of the Wayback Machine
Names the specific collection '52_crawl' and notes that it is currently not publicly accessible

Examiner rationale

The question uses contextual logic (researching archived sweepstakes websites) to indirectly point to the Internet Archive and its data sources without naming them (Deep). It then requires the respondent to identify the donating company and aggregate multiple specific facts: the start year of donations, the daily flow and embargo process, and the specific '52_crawl' collection and its accessibility status (Wide).

Judgment

Score 1 - 0

First, Deep Logic: Both agents correctly identify Alexa Internet (founded 1996) as the donating company and the Internet Archive as the nonprofit operating the Wayback Machine. So both pass the core entity check. Next, Width/Completeness: Both state donations began in 1996. Agent A explains the daily crawl flow, ARC/WARC formats, and specifically mentions an embargo period before incorporation into the Wayback Machine—this satisfies the checklist requirement about post-embargo integration. Agent B does not mention any embargo period, so it misses a required sub-point. Critically, both agents fail to name the required specific collection (“52_crawl”) and incorrectly describe accessibility (the checklist specifies it is not publicly accessible). Thus, both have factual gaps, but Agent B omits more required detail overall. Finally, Presentation & User Experience: Agent A is more comprehensive, better structured, and provides richer technical context about ingestion and indexing. Agent B is shorter and readable but less detailed and cites weak/irrelevant sources. Because both contain factual errors, the winner cannot receive MUCH_BETTER. However, Agent A provides stronger completeness and explanation, making it the better overall user experience. Therefore: A_BETTER, with Agent B failing on WIDE completeness.

The commercial web analytics company that has donated daily web crawl data to the Internet Archive is **Alexa Internet**. Founded in April 1996 by Brewster Kahle and Bruce Gilliat—who simultaneously established the Internet Archive—the company originally developed a web browser toolbar that provided site analytics, metadata, and automated recommendations [1]. To power its commercial indexing and traffic-ranking services, Alexa continuously crawled the live internet. In 1996, the company established a synergistic data donation relationship with the nonprofit Internet Archive by beginning to transfer its daily web crawl data [2]. This donated Alexa data served as the primary foundational content for the Wayback Machine when it officially launched to the public in 2001 [2]. The incorporation process dictates how this historical data is utilized. The Internet Archive receives the raw crawl files—traditionally packaged in ARC, and subsequently WARC, file formats—directly from Alexa. Following a standard embargo period, which historically lasted around six months, the Internet Archive processes the data by extracting and indexing all URL metadata [3]. These datasets are then seamlessly woven into the broader Wayback Machine index. This indexing ensures that the archived web pages can be retrieved instantaneously by researchers and users submitting targeted URL queries. One primary archival grouping associated with these specific donations is the **"Alexa Crawls"** collection [3]. The current public accessibility status of the "Alexa Crawls" collection is bifurcated into two distinct layers. Bulk access to the raw dataset files within this specific collection is heavily restricted and unavailable for direct public download by default [4]. This restriction mitigates mass extraction burdens and protects raw data integrity. However, while the raw bulk collection is locked, the individual historical webpage snapshots preserved within it remain entirely publicly accessible. Any user can freely view and interact with these individual page snapshots by querying their URLs through the main Wayback Machine web interface [3][4]. ## References [1] "Alexa Internet."

The commercial web analytics company is **Alexa Internet**, founded in 1996. The nonprofit digital library is the **Internet Archive**, which operates the Wayback Machine.[3] Alexa Internet has donated its daily web crawl data to the Internet Archive since **1996**, when both organizations began operations. This partnership enabled the Wayback Machine to grow rapidly, archiving billions of web pages from the mid-1990s onward.[3] The donated data—consisting of high-volume crawls capturing website snapshots, metadata, and link structures—are processed and incorporated into the Wayback Machine. Internet Archive engineers filter, deduplicate, and index this raw crawl data alongside their own crawls, creating time-stamped, publicly accessible archived versions of websites. These donations provided comprehensive coverage of the early commercial web, complementing the nonprofit's targeted crawls, and have been essential for historical research, including on online sweepstakes promotions preserved since the mid-1990s.[3] One specific crawl collection is the **Alexa Crawls** (also referenced as the "Alexa web crawl collection"). It remains **publicly accessible** today via the Wayback Machine at `https://web.archive.org/web/*/`, where users can browse archived sites by URL and date. For example, the collection powers views of promotional sites from 1996 onward, queryable through the CDX server API at `http://web.archive.org/cdx/search/cdx?url=example.com&fl=timestamp,original&filter=statuscode:200&collapse=digest`, revealing sequential captures from Alexa's donations.[3] This relationship has preserved over 500 billion web snapshots, supporting researchers studying ephemeral online promotions.[3] (Word count: 248) ## References [1] YouTube: Sweepstakes, Contests, and Other Types of Giveaways in the Digital Era [2] Internet Archive Blog: Boston Public Library Leads Once Again in Digital Lending [3] NPTechForGood: 94 Free or Low-Cost Tools and Resources for Nonprofits
