Stages 1 through 4 of the DSCRI-AGDC pipeline (Discovery, Selection, Crawling, Rendering) where the primary audience is the crawler/fetcher and the gating condition is zero-friction accessibility.

Jason Barnard defines the Bot Phase as the first segment of the DSCRI-AGDC pipeline where every optimization serves one audience: the crawler. Can it find your content (Discovery)? Is it worth fetching (Selection)? Can it access the content (Crawling)? Can it process the rendered page (Rendering)? Fail at any of these four stages and nothing downstream matters - the Algorithm never sees your content and the Person never encounters your brand. This is why Technical SEO is foundational, not optional. The Bot Phase maps to UCD's Understandability (U) dimension and Phase 1 of the Zero-Risk Year.
