Should I get a one-off SEO audit or a monthly retainer?
The featured-snippet answer, in plain language.
For most companies, start with a one-off audit; the diagnosis sets direction and tells you whether ongoing work is justified. A retainer is the right call only when the audit findings are already known, the volume of work is consistent, and ongoing execution is the bottleneck rather than direction-setting. Starting with a retainer without a baseline is paying for execution before knowing what to execute.
Why audit-first is the honest recommendation
The audit-first sequence is cheaper, faster, and produces a clearer baseline.
A common pattern across consulting engagements: a company hires a retainer agency, the first 90 days are spent auditing the site, and the actual implementation work begins in month four. The company has paid 3 to 4.5 months of retainer fees for what could have been a single audit deliverable.
The audit-first approach inverts this. You pay £750 to £1000 for the diagnosis upfront, get the report in 5 to 8 business days.
The retainer-first sequence is more common because it is what agencies prefer to sell, not because it is what most clients actually need.
What each one actually costs
| One-off SEO audit | Monthly retainer | |
|---|---|---|
| Up-front cost | £375-£1000 | $1,000-$1,500 per month |
| Annual cost (12 months) | £375-£1000 | $12,000-$18,000 |
| What you get | Diagnosis, prioritised plan | Ongoing execution, monthly check-ins |
| Time to first value | 5 to 8 business days | 30 to 90 days |
| Cancellation | No commitment beyond delivery | Monthly with notice (typically 30 to 60 days) |
| Right for | Direction-setting, one-off diagnosis | Active growth, execution capacity |
Both are valid. They serve different problems.
When an audit is the right call
-
01
You have not had a structured SEO review before, or the last one is more than 12 months old.
-
02
You suspect SEO issues but cannot name them specifically; you need a diagnosis before a treatment plan.
-
03
You are considering hiring an agency and want an independent baseline before being pitched.
-
04
You are resource-constrained and need clarity on the top three things to fix, not a 12-month engagement.
-
05
You want to try working with someone before committing to an ongoing relationship.
If any of the above describes you, start with the audit. It produces a written report you can act on independently, or use as the brief for whoever you hire next.
When a retainer is the right call
-
01
You already have audit findings (from us or another consultant) and the bottleneck is execution capacity.
-
02
You are in an active growth phase: scaling content, publishing weekly, pursuing link building consistently.
-
03
Your technical stack is complex (multi-region, multi-language, multi-domain) and changes happen frequently enough that ongoing oversight is valuable.
How most engagements actually unfold
The sequence we recommend, and why.
-
Audit (one-off)
£375-£1000. Diagnosis and prioritised plan delivered in 5 to 8 business days.
-
Self-implementation or small project (3 to 6 weeks)
You act on the top three to five findings, either internally or with hired help.
-
Ongoing support (only if justified)
If the volume of remaining work is consistent and execution capacity is the bottleneck, that is the point at which a retainer with someone starts to make sense. If not, the audit alone was enough and you avoided overcommitting.
The audit is the entry door. A retainer is one of several possible doors out, and it is not the default.
Common questions when deciding
Can I continue working with you after the audit?
Yes, but not on a retainer. We do not sell monthly retainers. If you want help putting the findings into practice, we scope that as a fixed-price project with a defined start and end, and the audit is the brief for it. There is no separate pitch and no obligation.
Do you offer a retainer yourselves?
No. Our product is the audit. If implementation help is useful afterwards, we scope it as a separate fixed-price project. A typical agency retainer covers technical implementation, content production, and ongoing optimisation; if that is genuinely what you need, an agency built around it will serve you better than we would.
Is a retainer cheaper than hiring in-house?
Usually, yes. A senior in-house SEO costs $80,000 to $150,000 per year fully loaded. A retainer at $12,000 to $18,000 per year buys senior-level decisions without the headcount; the trade-off is that it is part-time attention.
What if I just want one specific thing implemented (e.g., schema markup or a site migration)?
That is a fixed-scope project, not a retainer. Scope it separately; the audit can be the brief.
See the pricing page for audit pricing. Implementation projects are scoped separately, after the audit.
Start with the diagnosis
The cleaner first step for almost everyone is the audit. We can talk about ongoing work after, if and only if the findings justify it.
