Fact Density
Also: verifiable claim density
A sentence such as "we offer great service" gives an AI app nothing to repeat. A sentence that states the price, who does the work, where, and on what terms does.
Density is not length. A short page that states the facts plainly is more useful than a long page that restates them across padded prose. Every fact must be true and kept current, because a wrong price repeated by an AI app is worse than none.
