How Recruitment Agencies Should Budget for SEO

A recruitment agency should budget for SEO based on its market and goals, not a fixed figure, with the UK median SME retainer around £1,200 a month and competitive work at £1,500 to £5,000. Below roughly £800 a month buys automation, not strategy. The right budget funds a compounding asset, so it is weighed against job-board spend, not added to it.

Key Takeaways

SEO budgets scale with competition and goals, so there is no single right figure, but there is a floor.
The UK median SME SEO retainer is around £1,200 a month, with competitive work at £1,500 to £5,000.
Below roughly £800 a month tends to buy automated output, not genuine strategy.
A budget should be weighed against job-board spend, because SEO builds an asset that lowers cost per hire.
Dedicated AI visibility work typically starts from around £720 a month as an add-on.

There Is No Single Right Number

The first thing to accept is that SEO budgets vary with competition and ambition, so a fixed figure is the wrong question. UK SEO ranges from around £300 to £20,000 a month, and where a recruitment agency sits depends on its niche and goals, which is why budget follows strategy inside a recruitment SEO plan, not the other way round.

How much should a recruitment agency spend on SEO?

Enough to fund genuine strategic work for its market, which in the UK usually means £1,500 to £5,000 a month for competitive recruitment niches, and around the £1,200 median for smaller ones. Below roughly £800 a month buys automated output, so a realistic floor matters more than a headline price, the commercial reasoning in the 2026 revenue playbook.

What Each Budget Tier Buys

The second point is that budget maps to scope, so an owner should know what each tier funds. A one-off audit or blueprint is a project cost, while ongoing growth needs a retainer that compounds. For reference, Kaizen's own pricing runs from SEO Audits at £499, Blueprints at £795 and Overwatch monitoring at £275 a month, up to full retainers at £1,495 to £3,195 a month and a fixed-scope SEO Sprint at £9,995.

What does a recruitment SEO retainer include?

A retainer typically funds ongoing technical work, content, internal linking and reporting, with the scope rising by budget. At the strategic tiers it buys genuine strategy and execution rather than templated output, which is why defining the scope upfront matters, the discipline behind how content marketing fuels recruitment SEO.

Budget for AI Visibility Too

The third point is that AI visibility is now part of the budget, not an optional extra. Dedicated AEO work typically starts from around £720 a month as an add-on to SEO, and given buyers research suppliers in AI, that spend increasingly protects the pipeline, the focus of AI visibility for recruitment agencies.

Should a recruitment agency budget separately for AI visibility?

It should budget for it, whether bundled into a retainer or as an add-on from around £720 a month. Because ranking no longer guarantees citation, leaving AEO out of the budget means an agency can pay for SEO and still be invisible in the AI answers where clients now decide.

Weigh It Against Job-Board Spend

The final point is that SEO budget should be set against existing job-board spend, not on top of it. Boards charge per role indefinitely, while SEO builds an asset that lowers cost per hire over time, so an owner should plan to shift budget from recurring board fees toward a compounding channel as it matures.

Is SEO a better use of budget than job boards?

Over time, yes, because SEO compounds while job-board spend resets with every role. The sensible approach funds SEO while running boards, then moves budget across as organic and Google for Jobs take over, the cost logic behind why strong technical SEO and UX are now non-negotiable.

How to Set a Recruitment SEO Budget

Step 1. Define the goal and competition level, because they set the realistic range.

Step 2. Set a floor of at least around £800 a month, below which you buy automation, not strategy.

Step 3. Include AI visibility, bundled or as an add-on from around £720 a month.

Step 4. Fund it partly by shifting budget from recurring job-board spend to a compounding asset.
