The source notes that catering owners may expect visible SEO change in 4-8 weeks. Treat that as an expectation-management example, not a universal waiting period. A timeline is useful because technical discovery, indexing, query coverage, local visibility, inquiries, and commercial contribution do not move on the same schedule.
Use the timeline to decide what evidence should exist at each stage and when a lack of evidence warrants investigation. That is different from promising that rankings or bookings will appear on a fixed date.
Month 3 should be judged differently from month 6, and month 12 should be judged differently again. Each stage has different dependencies and diagnostic signals. The source also links to guidance on how to avoid ending a campaign before enough evidence exists, including a first 60 days reference that should be treated as planning context rather than a guaranteed minimum.
The sections below separate technical discovery, early coverage, meaningful visibility, and sustained commercial contribution so a catering team can judge progress using evidence appropriate to the stage.
