Google's own public advice to businesses hiring an SEO is unusually blunt for a company that rarely gives operational advice: interview the provider, check references, and ask for a technical and search audit before you sign anything. It's the kind of guidance you read once, nod at, and then forget the second a proposal lands with a tidy monthly number attached. Most buyers skip the diligence Google recommends, and that shortcut is why so many SEO engagements fall apart around the ninety-day mark.
The problem is almost never the agency's skill. It's the brief. Or rather, the missing one — a signed contract that never quite defined what was being bought, what would be reported, and what "working" was supposed to look like when month three arrived and someone finally asked.
Month Three Is Where the Missing Brief Shows Up
The first sixty days of an SEO engagement feel productive because they're designed to. Kickoff call, shared drive, audit deck, maybe a keyword map. Everyone is polite. Everyone is optimistic.
Then the honeymoon ends. Around week ten, the client starts asking the questions the contract should have answered up front. How many pages are we publishing this month, and who signs off? Who owns the technical fixes — us or the dev team?
The agency answers with what it can, but those answers don't quite line up with what the client remembers hearing during the pitch. Neither side is lying. They just never wrote it down.
By month three, the small mismatches have compounded. The client feels underserved, the agency feels micromanaged, and both are working from memory of a conversation that has since drifted. The retainer starts to feel expensive because nobody can agree on what it was supposed to buy.
Fix the Brief Before You Sign, Not the Contract After
The real work happens before the ink dries. A useful SEO brief describes the operating relationship, not just the outputs — how decisions get made, who has authority to approve what, and how the two teams will handle the things neither of them can predict.
Harvard's Program on Negotiation has written usefully on how to prevent this exact category of failure in services contracts, distinguishing input-based from output-based agreements and offering language for handling the inevitable additional-work requests. Their guidance on scope creep reads like a template for what an SEO engagement letter should include and almost never does.
A brief worth signing tends to cover the same handful of things:
- Decision rights. Who approves published content, technical changes, and link acquisitions — named humans, not "the client team." Include how fast approvals need to happen for the agency's plan to hold.
- The exclusions list. Everything the fee does not cover: dev implementation, translation, paid placements, migration support, out-of-scope requests. Ambiguity here is where month-three resentment lives.
- Reporting that matches the work. If the plan is a six-month technical foundation, the monthly report should show technical progress, not a traffic chart that won't move for another quarter. Agree on this before the first report, not after.
- Change-control language. A short paragraph on how new requests get scoped, priced, and slotted in. Without it, every "quick favor" erodes the plan you paid for.
- Offboarding terms. Who owns the content, the accounts, the tracking, the link register, and the working files when the relationship ends. Write it while both sides still like each other.
Know What Walking Away Actually Looks Like
Even a well-briefed engagement can go sideways. Strategies get overtaken by a business pivot, senior staff leave the agency, the market shifts. The buyers who handle this well decided, before they signed, what conditions would trigger a review — and wrote a notice period and a handover process into the contract so a review could actually end the relationship without a legal fight.
Walking away should be a procedure, not a crisis. If canceling means losing access to your own analytics accounts, your Search Console property, or six months of content the agency drafted, the contract was written to trap you.
A clean exit clause — thirty or sixty days' notice, full transfer of assets, no penalty for non-renewal — is one of the stronger signals that an agency is confident in its work. They don't need the lock-in because they don't expect you to leave.
Most of the failures buyers blame on "bad agencies" trace back to a briefing conversation that never happened. Slow down on the front end. Write the operating agreement, not just the price.
