Search Performance
So what do I intend when I throw around "search performance"? It's not just a shibboleth to compete with organic marketing and search engine optimization and the rest of it. Search performance is what I prefer to use when talking about search engine optimization, seo, and organic marketing as a whole. Not because I know necessarily any better, but when you think about it, it just makes more sense.
Search performance identifies a good working range of concepts. We can talk in terms of organic marketing, but to a certain extent I don't want to promote marketing. I want to see marketing as an emergent or ambient property of the overall performance of a site and its content in the realm of service to users.
Search performance means fulfilling the connection between searcher and searched. Search performance is the better term for what I want to promote because it describes the ultimate utility of what is profoundly a meta-activity. Search engine optimization and/or organic marketing represent the various tactics used to build the bridge between searchers and what they're searching for across the search engine(s). With the factual opacity of the biggest search engines (Google's proprietary algorithms, for example) and the functional opacity of the rest, the people delivering content through their sites, the users of that searched-for content, and the people trying to measure the effectiveness of both the searching and the presentation of the searched (whew!) can only guess if their efforts are working. Educated guesses, but guesses nonetheless, representing a chasm of knowledge. Even if the algorithms or methods were made public, like in Wikia perhaps, experience teaches that many laypeople and even many "experts" don't fully understand how search engines work--how they "know what to do" so to speak. This does not give us that much transparency. But you can measure search performance. The engines will, generally speaking, not tell you if you're "optimized". But the movement of traffic will describe for you a clear picture of your performance.
Search performance is the measurement of effects, found in data gathered at a remove from the end user.
