Weeks one to four are diagnostic and unglamorous. Crawl the site, map the queries that actually produce a sale, and score current position against the competitors ranking above you. Nothing visible changes. If an agency is publishing content in week two, they are guessing about what to publish.
Weeks four to twelve are technical repair and existing-page optimization. This is where the earliest movement appears, because fixing indexation and improving pages that already have some authority is far faster than earning authority from nothing. Expect ranking movement on mid-tail terms, not a revenue change.
Months three to six are architecture and production. New pages go live against the intents identified in the audit, and the internal linking structure gets rebuilt so authority flows where it should. Traffic starts compounding here, and the first meaningful lead volume usually lands in this window.
The first ninety days should produce evidence, not revenue. Confusing the two is why most programs get cancelled early.
Months six to twelve are authority and scale. Citations and links accumulate, the strongest clusters get reinvested in, and the weak ones get retired. This is where competitive head terms become winnable and where the compounding becomes obvious in the numbers.
The early signal worth watching is not ranking position. It is the number of distinct queries returning your site at all. Growth in query coverage precedes growth in position, which precedes growth in traffic, which precedes revenue. If coverage is not expanding by week eight, something is wrong.
