Efficient Frontier

Efficient Frontier was a digital advertising optimization and search marketing company founded in 2002 that applied algorithmic, finance-inspired bid optimization to manage over $1 billion in annual marketing spend across search, display, and social (notably Facebook ad buying) for enterprise clients such as Discover, Travelodge, and Match.com. Adobe acquired the company in late 2011 (announced November 30, 2011; completed January 2012) and folded its multi-channel ad forecasting, execution, and optimization capabilities into the Adobe Digital Marketing / Advertising Cloud. The efrontier.com domain now redirects to adobe.com and the company has no independent website, developer portal, or public API.

Efficient Frontier is profiled on the APIs.io network. Tagged areas include Company, Advertising, Digital Advertising, Search Marketing, and Social Advertising.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/efficient-frontier: open an issue to ask a question, or submit a pull request to add artifacts.
