Key facts
- 30 and 60 day written notice periods are the two most common cancellation terms in marketing agency contracts, covering most month to month services.
- A cure clause lets a client exit early without penalty if the agency misses agreed targets after being notified in writing and given a reasonable stretch of time to correct it.
- A reasonable early termination fee is calculated from a real cost, such as a portion of the remaining committed months, rather than applied as a flat penalty unrelated to actual cost.
- SEO retainers sometimes carry a longer minimum term than Google Ads management because meaningful ranking movement typically takes 6 to 12 months, longer than most Ads campaigns need to show results.
- SearchPod's agreements run month to month with standard notice and no early termination fee, backed by a 30 day guarantee across its services.
A Notice Period You Control
Most reasonable cancellation clauses ask for 30 or 60 days in written notice before the relationship ends, which gives both sides time to wrap up current work and plan a handover. Notice shorter than 30 days can leave an agency mid campaign with no time to close things out properly; notice longer than 60 days without a strong reason starts to look like a soft lock in rather than a practical transition window.
The clause should state clearly how notice must be given, such as written notice to a specific email or address, and when the clock starts, whether that is the date sent or the date received. Vague language like reasonable notice with no defined number of days is harder to enforce if there is ever a disagreement about timing.
Check whether the notice period differs by service. A 30 day notice for month to month Google Ads management and a longer notice for an active website build in progress are both reasonable, as long as each is stated separately and clearly.
A Minimum Term Tied to a Real Reason
A reasonable clause either has no minimum term at all, letting you cancel with standard notice from day one, or it has a minimum term matched to work that genuinely needs that time, such as an SEO retainer or a multi month website project. The reason for the minimum term should be explainable in a sentence, not just present because it benefits the agency's cash flow.
If there is a minimum term, a reasonable clause states the exact length, the exact end date once you sign, and whether the contract auto renews after that date unless you cancel. Open ended language that never quite tells you when you are free to leave is a sign the term was written to protect the agency more than to describe the actual project timeline.
A cure clause, letting the client walk away early if the agency falls short of agreed targets once notified in writing, is a strong addition to any minimum term and one you can reasonably ask for.
Exit Fees That Are Proportional, Not Punitive
If a contract includes an early termination fee, a reasonable version calculates it based on real, demonstrable cost to the agency, such as a portion of the remaining committed months or the unamortized cost of a discount you received for signing a longer term. An unreasonable fee is a flat penalty disconnected from any actual cost, designed mainly to make leaving expensive regardless of the reason.
Ask for the fee to be stated as an exact number or formula in the contract itself, not left to be calculated later at the agency's discretion. If an agency cannot explain how they arrived at a termination fee when you ask directly, that is worth treating as a signal on its own.
A reasonable clause also states that the fee does not apply if you are exiting under a cure clause for the agency's own underperformance, since a termination fee should never punish a client for leaving a relationship the agency itself failed to sustain.
What Happens Between Notice and the End Date
A reasonable clause states plainly that you keep access to your accounts, your website files, and any content or creative already produced, regardless of why the relationship is ending. It should also state whether ongoing work, like a campaign in flight or a page mid draft, will be finished, paused, or handed over as is during the notice period.
Ask what the final invoice will look like and when it is due, since billing in advance versus billing in arrears changes what you owe on the way out. A reasonable clause states this plainly rather than leaving it to be settled by email after notice has already been given.
Overall, a reasonable cancellation clause reads like it was written to describe a fair, orderly exit for either side, not to make leaving as difficult or expensive as possible for the client alone.
Related questions
It is one of the most common notice periods, along with 60 days, and either is generally considered reasonable for month to month services like Google Ads management. Notice shorter than 30 days can be tight for both sides to wrap up properly, while notice much longer than 60 days without a clear reason starts to function like a soft lock in.
A fair fee is tied to a real, calculable cost, such as a portion of the remaining committed months on a minimum term contract, and it should be stated as an exact number or formula rather than left open ended. A flat penalty with no connection to actual cost, or one applied even when the agency underperformed, is not a fair structure.
Only if your contract includes a cure clause allowing it. Otherwise, standard notice periods still apply even to underperformance, unless the contract specifically defines termination for cause. This is why a cure clause, which lets you exit without penalty after flagging the issue in writing and giving the agency a chance to fix it, is worth asking for before you sign.
It often is, and reasonably so. SEO retainers sometimes include a longer minimum term because ranking results take 6 to 12 months to build, while Google Ads management, where results and problems appear within a month or two, more commonly runs month to month. Either structure can be fair as long as the reason for the difference is clear.
Ask the agency in writing to confirm the notice period they expect, since a contract silent on cancellation does not mean you cannot leave, only that the process is undefined. Get their answer in writing before you act on it, and treat the absence of any written clause as something worth fixing in your next agreement, wherever you sign one.
