The Short Answer
A traditional SEO agency usually sells an open-ended monthly retainer delivered by a mixed team, with volume-based deliverables. A senior-led consultancy scopes work against a specific business outcome, keeps experienced practitioners on the account and hands over the playbooks so your team owns the results. Agencies suit businesses that want ongoing execution at volume; consultancies suit businesses that want a defined outcome, senior attention and internal capability.
Two Ways to Buy SEO
Most businesses buying SEO end up choosing between two models, often without realising they are different. Both can work. The wrong fit is what wastes budget.
A traditional agency retainer is a monthly fee for an ongoing bundle of activity - a set number of articles, links, audits and reports. A senior-led consultancy is scoped around a business problem: diagnose what is holding growth back, agree the number to move, ship against it, and leave the client with systems they can run.
Side-by-Side Comparison
Pricing
Agency: monthly retainer, often tied to deliverable volume.
Consultancy: fixed scope or fixed monthly fee tied to agreed outcomes and workload.
Who does the work
Agency: senior staff often sell and oversee; delivery may sit with junior or outsourced teams.
Consultancy: experienced practitioners stay on the account from start to finish.
Scope
Agency: broad packages designed to fit many clients.
Consultancy: work prioritised by a diagnostic of your specific constraints.
Reporting
Agency: activity reports - links built, posts published, rankings.
Consultancy: business metrics - qualified traffic, pipeline, revenue contribution.
Ownership
Agency: processes and tooling often stay with the agency.
Consultancy: playbooks, documentation and access handed to your team.
Exit terms
Agency: long minimum terms are common.
Consultancy: short setup periods, then flexible terms.
These are general patterns, not rules. Some agencies run excellent senior teams; some consultancies overpromise. Use the comparison to ask sharper questions, not to judge a provider by label.
When a Traditional Agency Is the Better Fit
- You need a high volume of content or links produced continuously
- You have no internal marketing team and do not plan to build one
- Your strategy is already clear and you mainly need execution capacity
- You value a single vendor covering many channels at a predictable monthly cost
When a Senior-Led Consultancy Is the Better Fit
- You have spent on SEO before and cannot connect it to revenue
- You need to know what is actually limiting growth before committing budget
- You want experienced people doing the work, not just reviewing it
- You plan to build internal capability and want systems you can run yourself
- You operate across several markets and need one consistent approach
Questions to Ask Any SEO Provider
- Who, by name, will do the work each week?
- What will you measure, and how does it connect to revenue?
- How do you build links, and which tactics will you never use?
- What do we own - content, data, accounts, documentation - if we part ways?
- What is the minimum term, and what does leaving look like?
- Can you show work in a situation similar to ours?
A provider that answers these clearly is worth considering whatever model it follows. For more on what good SEO work involves, see why businesses use professional SEO and link building consultancy and how long SEO realistically takes.
How AiS LABZ Works
AiS LABZ is a senior-led consultancy. Engagements follow the LABZ protocol: diagnose the constraint, model the economics, build in two-week increments and hand over the playbooks. Fees are fixed with no hidden line items. Subscriptions for SEO, performance marketing and platform maintenance run month-to-month after an initial three-month setup period, and the same senior pod delivers the work in every market we serve.
That model is not right for every business - and if an agency retainer suits you better, we will say so.
Common Questions
FAQ
Not necessarily. Consultancies often charge more per hour because the people doing the work are more experienced, but tighter scoping can mean less total spend. Compare cost against the outcome delivered, not against the volume of activity.
Yes. Before switching, make sure you have access to your analytics, Search Console, content and any link-building records, and check your current contract's notice period.
SEO takes time to show results, so a short initial period of around three months is reasonable. Be cautious about long lock-ins with no performance review or exit clause.
It depends on what is missing. If you lack strategy and want to understand what will work, start with a consultancy-style diagnostic. If strategy is clear and you need ongoing production, an agency may be more efficient.
