What are some verticals where building you own structured data could be a viable business?<p>I asked this 2.5 years ago and believe there is still plenty of opportunity following this model.<p>For example, here is the rough general model:
* Identify a vertical with large number of distinct data sources
* Create structure around the data
* Make the data browseable and searchable
* Allow users to supplement data with their own content (usually in the form of reviews/ratings/organization)<p>Growth model:
* Expose smaller set of high quality pages
* Gain first users by promoting in target market blogs/forums/news channels
* SEO heavy
* Expand when there is enough data coverage
* Focus on utility first
* Layer in social for added distribution<p>Here are some verticals with existing businesses that roughly follow this model:
* Travel - TripAdvisor
* Jobs - Indeed
* Laywers - Avvo
* Doctors - Avvo/Vitals
* Movies - IMDB
* Used Products - Priceonomics
* Local - Yelp
* Autos - CarGurus<p>What do you think are some good opportunities to apply the structured data biz model?<p>A few thoughts:
* Disease / Medicine - It's still hard to get the information I want.
* Schools / Degrees / Expected Career Success - Extremely hard to compare higher education schooling options.
