What an SEO retainer costs
A retainer is a fixed monthly fee for ongoing SEO. Here’s what they typically cost, what they should include and how to get out of one.
Typical retainer prices
Whito’s UK agency retainer research puts single-channel agency retainers, including SEO, at roughly £1,250 to £3,500 a month, with SEO among the more expensive channels because it needs sustained technical work. Full-service retainers covering several channels cost considerably more.What a retainer should cover
A clear set of monthly tasks. Regular reporting. Access to the people doing the work. A plan that changes as results come in. If your retainer has run for months and you can’t say what was done, something’s wrong.
Notice periods and minimum terms
Many retainers come with a minimum term, often several months, and a notice period after that. Read the contract before signing. A long term isn’t automatically bad, but it means you carry the risk if it doesn’t work out.
How automation changes the maths
A big part of any retainer is time spent checking: crawling, spotting broken pages, reviewing titles. Software does that every day without billing by the hour. Automating it means a lower fee, or more time left for the work that needs a person.
Getting value from a retainer
Agree three or four goals at the start, such as more enquiries for a particular service or better visibility in two towns. Ask for a short plan each month linked to those goals. Review progress every quarter and drop work that isn’t helping. A retainer works best when both sides know what success looks like and can see whether it’s happening. And keep the relationship honest both ways. Tell your provider about changes in your business, such as new services or a new area, so the work stays pointed at what matters.
What agencies charge for SEO retainers
Whito’s agency benchmark puts single-channel SEO retainers at £1,250 to £3,500 a month (rate cards and surveys, January to May 2026), with a core range of £1,250 to £3,500 for most small and medium firms. Whito also notes that SEO tends to be the most expensive single-channel retainer, because it needs sustained technical work.
Read the term before the fee
Whito points out that agencies often discount longer contracts by 10% to 15% a month. That can look good until the work disappoints and you’re stuck. A rolling monthly arrangement costs nothing extra to leave, so the provider has to keep earning your money. Weigh the saving against the risk.
What a retainer report should show
Each month you should see the work done, the pages changed, any problems found and fixed, and the plan for next month. Over a quarter, you should see a trend in Search Console: more pages appearing in searches, and clicks moving the right way. If you can’t see either, ask why.

Common questions
What’s a normal notice period?
It varies. Many agencies ask for a minimum term. Ours has none: cancel before your next month starts.
Do retainers include link building?
Some do, often at extra cost. Ours doesn’t include outreach or link-building campaigns. It does include local SEO basics such as Google Business Profile tidy-ups.
Is a retainer worth it for a small firm?
If the work is clear and you can leave freely, it can be. Whito suggests very small firms often fix the basics first.
