I have a SEO question for single page applications. We're working on a SPA (not yet public) that displays tables of numeric data to users.The data volume is large, number aggregations are costly and consistent state must be kept under a high number of concurrent users. All of these cause high strain on the servers.Since this is an AJAX application, for crawlers we serve HTML content following recommended practices (like e.g. ?_escaped_fragment_=...).The application is optimized for usage patterns that a human user would generate, but a crawler indexing the entire site would cause a spike.The application's architecture allows us to scale both vertically and horizontally but that means more money spent on hardware. A cheaper solution would be to serve the search engines the HTML content with random data in it, instead of the real numbers that are costly to generate.Everything will be the same as what a user would see in the browser but with random numbers. Search engine wouldn't make sense of the numbers anyway so there is no point in loading the servers to build them.As I said, my question is SEO related. We're not trying to do SEO optimizations or tricking search engines, we just want to lower the load on the server. But we're worried this would impact the ranking of the application? So would it?
For performance reasons: have different pages for search engines and users
