Almost one year on since Yahoo Answers launched in December 2005, we’re taking a look back at how it has grown and where the future lies for the Q&A website model.For those of you yet to hear of, or experience Yahoo Answers, it is essentially a platform enabling registered users to pose questions to others within an online community. Each response can be rated, and a single answer can be chosen as the best. A merit system deducts points from a user for asking a question and rewards them for answering others.
So if the Q&A model failed six years ago, why would it work today?
This is an interesting question which can be answered 2 different ways. For the search engines, their Holy Grail is to offer a perfect set of answers for every search query, every time. Many say that bad natural search results increase clicks on paid search and is therefore to the engine’s advantage; although it’s proven that internet users are more then willing to change search providers if they’re unable to find what they’re looking for first time. In contrast, giving the search user a selection of quality answers (including paid search), one of which offering the user exactly what they need, heavily increases user retention.
Where does the Q&A platform fit into this? Search Engines mostly rely on their core algorithm to filter, analyse and rank each indexed web pages for natural search results. Although small teams of human editors work to manually filter out some pages such as spam, the mathematical algorithm is relied upon for the most part. Even with additional algorithms such as PageRank aiming to add a democratic style of human interactive voting to search ranking (through analysing links), this is still a mathematical equation which can be manipulated, no matter how relevant or irrelevant a page is to the user’s query.
A database of answered questions, like what Yahoo now holds, is a very valuable commodity. Not only are questions asked by verified users, but a democratic collective also choose the best answers. Integrating this into mainstream search, if a user queries [what is a royal flush?] or [viagra side effects], the engine can show results from its “Best Answer†archive and most likely offer a more credible and useful set of results then the usual affiliate and “Made For AdSense†sites which appear for such queries. As the platform exists entirely on Yahoo’s network, every aspect of the Q&A process can be (and is) moderated and controlled by their staff.
The other reason why a Q&A model may work in today’s online society, is the mixture of highly relevant contextual advertising and a more open “social networking†community. Few advertising networks could offer real content targeting in 2000, mainly working on a basis of website or individual site section topics. The ability of companies such as Google to read a page and pinpoint the best paid advertising based on each individual page’s content is of tremendous benefit. Where as before there would be Ford advertising their new saloon on a Q&A page about fixing the exhaust on a Jaguar XK8, now community sites are able to serve relevant adverts for Jaguar Garages and Jaguar DIY Mechanic Books. As a result, the commercial opportunities through much higher Click Through Rates and greater overall ad revenue, now makes the business model much more viable.
One website looking to challenge Yahoo’s share of Q&A enthusiasts is AnswerBag, founded in 2003 by Joel Downs, who sold the company earlier this year to InfoSearch Media. Just last month, Answerbag was sold a second time to Demand Media (owners of rival Q&A website eHow) for 3 million dollars. The website itself reminds me of a young YouTube, free from rich media adverts cluttering the page or Calls To Action for “Premium†services. The actual advertising on the site takes some time to find, hidden under a “Related Ad Categories†menu on the side bar and powered by the Ask.com advertising network. Coupled with equally popular site eHow, AnswerBag is no longer a minnow - and I’m sure it has already caught the eye of big fish such as News International and the former owner of MySpace. Its current threat to Yahoo is still minimal however, with less than 2% of Yahoo’s unique visitors according to data obtained from comScore World Metrix:
