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

Typically, SEO agencies are staffed by a mix of specialists, including SEO specialists, developers, account managers and writers.

This breadth enables them to tackle large or multifaceted campaigns that benefit from multiple perspectives.

For businesses that require an end-to-end solution, working with an agency can be highly efficient.

Still, in cases where only one or two skill sets are required, such as SEO or PPC, this approach may be more than is necessary.

2. Cost-Effectiveness

Winner: Consultant

Whilst agencies can pitch competitive prices, those numbers often include the expense of physical offices, administrative staff, and middle management.

Consultants tend to operate independently. That means your money goes directly towards their expertise, not business overheads.

For many, this makes SEO consultants the more cost-effective solution.

3. Resources

Winner: Agency

Agencies tend to be a strong option for large projects, simply because they have more people to draw upon.

They’re able to spread tasks across a team, which can speed up delivery and manage multiple campaign strands.

If your business requires this level of resource, an agency might be the better route.

4. Adaptability

Winner: Consultant

With multiple teams to coordinate, agencies often lean on standard operating procedures to keep things running smoothly.

While the individuals you deal with may be flexible, the broader team might take time to adjust to changes in direction.

Consultants offer a more fluid experience. They can shape their work around your needs and change tack as required.

That sort of adaptability is invaluable when digital trends shift rapidly.

If, mid-project, you decide to revise your SEO approach, a consultant is generally quicker to implement changes than an agency working through layers of process.

5. Communication

Winner: Consultant

A key advantage of working with a consultant is having one consistent point of contact throughout the project.

This means you avoid the common agency experience of being handed from one account manager to another or dealing with staff changes mid-way through.

With a consultant, communication tends to be clearer and more direct, as you’re speaking to the person actually doing the work.

This kind of connection not only saves time but also helps foster a stronger, more collaborative relationship.

6. Personal Service

Winner: Consultant

SEO consultants have a personal stake in your success, as their reputation and income rely directly on the results they deliver and your satisfaction.

Unlike agencies, where responsibilities are often spread across teams and overseen by senior management, consultants are focused solely on you.

This usually results in a higher level of care and commitment.

While an agency might view you as just another account, a consultant sees your growth as a direct measure of their own performance.

7. Quality of Work

Winner: Equal

You can get excellent SEO support from both agencies and independent consultants.

Agencies often involve a range of specialists, but that sometimes means the work is distributed to junior staff for training.

Consultants tend to manage every detail themselves, resulting in a more consistent and focused execution.

Final Score

  • Agency: 3
  • Consultant: 5
