How long should an SEO contract run?
There's no standard length, and published advice ranges from three months to a year. SEO takes months to show, so a short first commitment is reasonable. What matters more is what happens after it: a fair contract moves to month to month, while a trap renews for another full term. Judge the term and the exit together.
The published views disagree on the number. One agency guide calls three months "a reasonable minimum commitment to see early directional results". Others put the baseline at three to six months, or call six months a reasonable start and warn that "Twelve-month commitments lock you in before you've had time to evaluate performance." A consultant's guide, updated October 2026, calls 6 to 12 months standard but asks for progress targets at months 3, 6 and 9.
Google doesn't publish a timeline either. Its starter guide says, "Some changes might take effect in a few hours, others could take several months." So a long term isn't automatically unfair, but it should come with a way out if the work you were promised doesn't happen. Our guide to ranking guarantees explains what a provider can fairly promise in that time.
