First visible ranking changes — 4-8 weeks after starting. Noticeable traffic growth (2-3x) — 3-6 months. Reaching a plateau on main keywords — 9-12 months. These are realistic numbers for an average site in a moderately competitive niche. In highly competitive niches (legal services in major cities, finance, healthcare) — double the timeline.
Search engines (Google, Bing) intentionally delay trust in new changes. It's anti-manipulation protection: if every edit gave instant results, the SERP would be easy to hack. Google uses a "sandbox" mechanism for new sites and "trust evaluation" for changes on old ones.
"Paid for 3 months — no result, we quit." This closes the funnel right before Phase 2-3, when SEO starts paying off. Minimum SEO contract — 6 months. Better 9-12. If an agency promises "top in a month" — they're either scammers, or using black-hat methods that will get the site penalized.
