Instead of asking for one date when SEO is "working," evaluate the program by the kind of evidence that should exist at each stage. Organic search develops through overlapping workstreams, and a later commercial outcome cannot be inferred from an earlier technical milestone.
Stage 1: Foundation (Months 1-3)
The first stage covers crawlability, indexation checks, site architecture, measurement, practice-area and geographic research, content prioritization, and competitor review. The objective is to make the site technically understandable and establish a baseline that can be compared later. It is too early to treat limited inquiry movement as proof of failure or future success.
Decision check: confirm that important pages can be discovered, analytics and intake attribution are functioning, the content plan matches real legal-service demand, and known technical blockers are being addressed.
Stage 2: Early Coverage (Months 4-6)
At this stage, newly created or revised pages may begin appearing for a broader set of relevant queries. On-page improvements, internal linking, and legitimate authority work can start producing observable movement, but volatility is normal and not every query will move together.
Recorded source observation: the source previously cited 3-8 monthly inquiries for some campaigns and page 2-3 visibility for certain primary terms. Without supporting methodology or source URLs, treat those figures as historical observations rather than benchmarks to promise.
Stage 3: Meaningful Visibility (Months 7-12)
By this stage, a firm may have enough indexed content, internal connections, citations, and historical search data to judge whether visibility is broadening across commercially relevant topics. The source records 20-40% month-over-month inquiry growth and 8-20+ monthly inquiries in some prior campaigns, but those values are not verified causal outcomes and should be reconciled against your own market and intake data.
Stage 4: Sustained Commercial Contribution (Month 13+)
The later stage is about quality and efficiency: which queries produce qualified matters, which pages deserve refinement, where genuine locations or practice areas justify expansion, and whether commercial contribution is improving relative to total investment. The source notes that 12+ months of data can make trend analysis clearer; that is an observation about measurement depth, not a guaranteed ROI date.
