I can see how you'd have that perception but the term covers a wide swath of use cases. Search engine spam is not nearly the issue it once was. Most SEO pages are created to account for two things: product marketing content cannot contain all the possible terms that people use when searching without becoming unintelligible and data served dynamically through SPAs, especially geographically localized data, is still challenging to expose to search engines even with universal apps.
Could you fill me in? Why do SEO pages suck users time? I'm a newbie.
SEO pages are crap meant to make a site with otherwise no interesting content (else it would have used that) rank higher on Google.
