Do you need a twelve-month SEO contract?

Usually not, though the case for one is stronger than we'd like, and some of it is right. SEO does take months to show: for years, Google's own guidance said four months to a year was typical. What doesn't follow is that you need to be locked in for a year to get the work done, or that a long contract protects you as much as it protects whoever is selling it.

Our interest, stated first. We sell SEO as a fixed-price project, an SEO audit and first fixes for £2,500, with ongoing work available month to month and no minimum term. So the answer that suits us is no. We've tried to argue the other side as hard as the evidence allows, and where it holds, we say so.

This piece is part of our series on marketing myths, checked, which checks what small and medium businesses are told against what the people running the systems actually publish.

What decides how long the work takes

Most of what sets the pace isn't in the contract at all. How long SEO takes depends on several things, and these matter most:

• The state of the site. If anything is stopping Google from listing your pages, that has to be fixed before anything else can work.
• How competitive the searches are. A local service in a market town is a very different task from a national search.
• Local or national. For local searches, Google says results are "mainly based on relevance, distance and popularity", and that how well known a business is depends partly on "how many websites link to your business and how many reviews you have".
• How much content needs writing. A page that doesn't exist yet has to be written, then found by Google, then judged against what already ranks.
• How quickly changes are made. Most of the work is changes to your own site, so if they're waiting for your developer or your sign-off, the clock waits with them. Until June 2026, Google's guidance on hiring an SEO told site owners to "Be committed to implementing the recommended changes", because "Making the changes recommended by an SEO takes time and effort", as an archived copy from June 2025 shows.

When Google says results appear

Google gives ranges rather than dates.

• After a change, Google has to visit and read the page again, and its help on asking Google to recrawl your URLs says "Crawling can take anywhere from a few days to a few weeks".
• Its SEO starter guide says: "Some changes might take effect in a few hours, others could take several months. In general, you likely want to wait a few weeks to assess whether your work had beneficial effects in Google Search results."
• For improvements to a site's overall quality, Google's guidance on core updates says "it could take several months for our systems to learn and confirm that the site as a whole is now producing helpful, reliable, people-first content in the long term", and that if nothing has changed after a few months, "that could mean waiting until the next core update".

For years, Google also put a number on it. Its page on hiring an SEO said: "Remember that it will take time for you to see results: typically from four months to a year from the time you begin making changes until you start to see the benefits." The line was still there in April 2026, as an archived copy from 23 April 2026 shows, but it isn't on the current page, which Google rewrote on 5 June 2026 "to simplify and modernize the content" and "remove outdated examples", according to its documentation updates page. Google never said it had changed its mind about the timeframe, so we don't read the removal as a sign that results come faster now. Google simply no longer puts a number on it.

That's the strongest point for the other side, and it cuts against the way we sell. Our own audit and first fixes takes about four weeks, and on Google's own figures most of the benefit will arrive after the project has finished. A fixed price buys a defined piece of work, not results inside the project, and anyone selling SEO in short projects, us included, ought to say so.

What a long contract protects, and for whom

A twelve-month contract protects both sides, but not equally, and not in the same way.

For the agency, it protects income. It lets the agency recover the work done at the start, such as an audit, a strategy and the set-up, across twelve monthly payments instead of charging for it all up front. It also lets a larger agency hire and plan around a workload it can count on.

For you, it can buy a lower monthly price, a rate that can't rise for a year, and people who have set aside time for your account. Those are real benefits, and a supplier offering them in return for a commitment isn't doing anything wrong.

The risk sits with you. If the work isn't done, or is done badly, you're still paying. And because you're buying as a business, most of the protection a consumer would get doesn't apply to you. The Consumer Rights Act 2015 defines a consumer as "an individual acting for purposes that are wholly or mainly outside that individual's trade, business, craft or profession". The new rules on subscription contracts apply to "a contract between a trader and a consumer", and they aren't in force yet: the government says they start in January 2027. Neither covers a business. So if you're a business buying SEO, the contract itself is most of the protection you have.

The honest case for a long contract

We've argued against our own interest this far, so here's where a twelve-month commitment does make sense.

• When you'd otherwise stop too early. If the work takes months to show and you'd judge it at week six, a commitment can stop you abandoning something that was about to pay off. That's a real risk, and the fix is to agree in advance what should have moved by when.
• When the price reflects it. If committing for a year brings the monthly price down, or means the audit and set-up aren't charged separately, compare the total cost over the year rather than the monthly figure.
• When the programme needs planning. A year of content or outreach, planned and scheduled, is easier to deliver and staff than one month at a time.
• When continuity matters to you. A supplier that has reserved time for you for a year is less likely to move its best people elsewhere.

What all four have in common is that the benefit comes from the plan and the price, never from being unable to leave.

How to get the benefits without the lock-in

• Agree a twelve-month plan in writing: what will be done, in what order, and what should change by when.
• Pay for upfront work separately, so the monthly fee doesn't have to recover it.
• Work month to month with a clear notice period, or take a longer term with a break clause after the first three months.
• Review against measures you can check yourself: pages indexed, and impressions and clicks for the searches that matter, all in Search Console. Google's current guidance on whether you need an SEO says an audit "should be about giving you realistic estimates of improvement, and an estimate of the work involved".
• Keep the accounts in your own name, so that leaving costs you nothing but the relationship. If you're not sure who owns your marketing accounts today, find out before you sign anything.

Before you compare proposals, it helps to know how much SEO costs in the UK and what an SEO audit should include.

A quick check before you sign

Before you sign up for a long SEO term, check these four things:

• I know what will be done each month, not just what it costs.
• I've compared the total cost over the term with the alternatives.
• Upfront work is priced separately, or I know how much of the monthly fee is paying it back.
• There's a break clause after the first few months, or a notice period I can live with.

Then put the proposal through the six checks every quote should pass, which include who owns Search Console and analytics, and the measure and date you'll judge the work by.

What nobody has measured

• How long SEO takes for a business your size. We found no independent study measuring it. The figures people usually quote come from SEO software companies and agencies, with samples and methods that are hard to check, so we haven't used them.
• Whether contract length changes outcomes. We found no data comparing results under long contracts, rolling contracts and fixed projects.
• Why Google removed its timeframe. Google's documentation update describes simplifying the page and removing outdated examples. It doesn't say whether Google still considers four months to a year typical.

So, do you need one?

Usually not, though the reason people give for one is partly right. SEO does take months, and planning a year of work is often exactly right. Being locked into a year is a different thing: it protects the supplier's income first, and a business buying SEO has little protection beyond the contract itself. So plan for a year, pay for what gets done, keep the accounts in your own name, and make sure you can leave if the work stops.
