Yedda was an Israeli question-and-answer (Q&A) platform driven by its community, distinguished for its pioneering commercial application of semantic search and vector similarity techniques to link user inquiries with pertinent answers and specialists. Established in late 2005 and publicly launched in early 2006, the service grew through syndication agreements before being purchased by AOL in November 2007. Operating as a fully owned subsidiary, Yedda’s technology was globally reintroduced in 2010 under the name AOL Answers, which at one time attracted the highest volume of organic search traffic among AOL’s offerings.
Establishment and public debut (2005–2006)
The company was created in 2005 by Avichay Nissenbaum (CEO), Yaniv Golan (CTO), Osher Frimerman (VP R&D), Eran Sandler, and Daniel Verhovsky. The founding team raised around US$2.5 million in initial funding and initiated a soft launch of the Q&A platform toward the end of 2006.
Expansion and partnership network
Yedda broadened its audience by licensing embeddable Q&A widgets to more than 50 affiliated websites, such as ePals and The Job Network. By late 2007, these partners were responsible for roughly 90% of Yedda’s overall visitor traffic.
AOL acquisition (2007)
On November 11, 2007, AOL disclosed its acquisition of Yedda for an undisclosed sum, widely reported to be in the multi-million dollar range. This transaction represented AOL’s **fifth acquisition in Israel**, following Mirabilis (ICQ), Relegence, Quigo, among others. AOL maintained Yedda’s research and development center in Tel Aviv along with its founding personnel as a wholly owned subsidiary operating independently.
Transition to AOL Answers (2010)
In August 2010, the platform was rebranded as AOL Answers, with user profiles and archived content migrated to the new system while promoting the brand across AOL’s portals. Industry analysts observed that despite modest revenue per page, the extensive long-tail Q&A content attracted millions of search-based visits, briefly making AOL Answers the largest source of organic traffic within AOL.
Technology and features
At the heart of Yedda was a **semantic matching system** that examined both syntactic and conceptual aspects of questions to:
- assign topic tags;
- identify semantically related questions and answers; and
- engage users possessing relevant expertise to provide responses.
This approach established a “distributed expert network” that directed queries to the most suitable respondents. Yedda’s proprietary technology is protected by patents including:
- , “*Method and system for extending keyword searching to syntactically and semantically annotated data*” (granted 2009);
- , “*Device, system and method of handling user requests*” (published 2008).
Experts in the field recognized Yedda as one of the earliest commercial uses of vector-distance metrics—an initial form of “vector search”—within consumer-facing web applications.
Reception and legacy
Alongside peers such as Yahoo! Answers, Aardvark, and later Quora, Yedda earned acclaim for its intelligent question-answer matching and community engagement. After acquisition, **AOL Answers** became a major driver of SEO traffic for AOL, even though monetization lagged behind its growth in page views. The service was gradually discontinued during the mid-2010s; however, Yedda’s early innovations in semantic linking foreshadowed methods later employed in natural language processing and large language model search technologies.
