When considering SEO services for your business, one decision you will have to make on the way is choosing between an SEO agency and consultant (in fact, you most likely clicked on this article to help with that exact decision!).

While both agencies and consultants aim to improve your website’s search engine rankings, their approach, structure, and relationship with clients differ significantly.

  • SEO agencies typically consist of multiple people skilled in SEO, account managers, developers, admin staff and directors.
  • SEO consultants on the other hand are just the person skilled in SEO, covering admin duties themselves.

To help you decide between the two, I’ll compare both against seven key factors that are important to businesses deciding between choosing an agency or a consultant:

  1. Variety of Skills
  2. Cost-Effectiveness
  3. Resources
  4. Adaptability
  5. Communication
  6. Personalised Service
  7. Quality of Work

1. Variety of Skills

Winner: Agency

SEO agencies, by nature, typically have a broad team of experts including SEO specialists, developers, account strategists, copywriters and more.

This diversity allows agencies to handle projects requiring multiple skill sets across teams.

For businesses needing a wide range of services, an agency can provide a one-stop solution.

However, this breadth of skills may not always be necessary for projects requiring only 1-2 skill sets (e.g. SEO/PPC).

2. Cost-Effectiveness

Winner: Consultant

Agencies can provide competitive rates, but it’s worth remembering they also carry the costs of office premises, management teams, and support staff.

Independent consultants generally avoid these overheads. You’re paying for their skills and experience, not the extra layers that come with an agency structure.

All things considered, SEO consultants often represent the more economical choice.

3. Resources

Winner: Agency

When it comes to large-scale SEO work, agencies often shine due to having a wider team available.

They can deploy several people to manage different parts of your campaign simultaneously.

If your business needs that kind of capacity, choosing an agency may be the best move.

4. Adaptability

Winner: Consultant

Agencies typically follow structured systems, which help coordinate large teams but can slow things down when changes are needed.

Even if your main contact is responsive, broader adjustments can take time to flow through.

Consultants offer a more bespoke service and can respond to changes without delay.

In fast-moving digital markets, that flexibility can be crucial.

Let’s say you want to tweak your SEO focus mid-campaign – a consultant can often do so quickly, while an agency might need to run it through internal processes.

5. Communication

Winner: Consultant

One of the most valued aspects of working with a consultant is the consistency they provide through a single point of contact.

It avoids the all-too-common agency scenario of switching account managers or navigating high staff turnover.

With a consultant, you’re in direct contact with the person who knows your project inside out.

This clear line of communication builds efficiency, trust, and a stronger long-term partnership.

6. Personal Service

Winner: Consultant

SEO consultants are personally invested in your success because their livelihood depends directly on their results and client satisfaction.

Unlike agencies, which often report to directors or larger management teams, consultants focus solely on your needs.

This personal attention often translates into better service and more dedication.

For example, while an SEO agency may treat you as one of many clients, a consultant sees your success as a reflection of their own.

7. Quality of Work

Winner: Equal

Both options – agencies and consultants – are capable of delivering quality SEO.

Agencies may have the benefit of larger teams, though this can also mean tasks are passed around and handled by less experienced staff.

With consultants, you get a single, dedicated professional managing the entire process with close attention to detail.

Final Score

  • Agency: 3
  • Consultant: 5
