When considering conversion rate optimisation (CRO) services for your business, one decision you will have to make on the way is choosing between a CRO 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 conversion rate, their approach, structure, and relationship with clients differ significantly.

  • CRO agencies typically consist of multiple people skilled in different aspects of CRO, account managers, developers, admin staff and directors.
  • CRO consultants on the other hand are just the person skilled in CRO, 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, CRO agencies are staffed by a mix of specialists, including CRO 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 CRO or SEO, this approach may be more than is necessary.

2. Cost-Effectiveness

Winner: Consultant

Whilst agencies can offer competitive pricing, but their rates are often inflated by office-related expenses, management layers, and admin teams.

Freelance consultants usually sidestep these costs. You’re engaging directly with an expert, minus the extras.

As a result, CRO consultants often provide a more affordable alternative.

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

Agencies, with their multi-person teams, tend to run on streamlined processes to manage workflow across accounts.

This can mean that adapting your account setup or strategy involves multiple steps and takes longer than expected.

Consultants are more agile. They’re able to adapt their work directly to your evolving needs without the red tape.

In a fast-moving digital world, this kind of responsiveness can make a real difference.

If plans change, a consultant can often pivot within hours – something agencies may struggle with due to approval chains and team structures.

5. Communication

Winner: Consultant

One of the clear benefits of choosing a consultant is consistency – you’ll deal with the same person throughout your project.

Unlike agencies, where staff changes and account handovers are more common, consultants provide stability.

You’re in touch with the individual doing the actual work, not a middleman.

That makes communication simpler and helps to build a more genuine working relationship.

6. Personal Service

Winner: Consultant

Consultants rely on strong results and client satisfaction to sustain their business, so they’re often more personally invested in your success.

They don’t have directors or departments pulling them in different directions – their energy is focused squarely on helping you achieve your goals.

That level of personal accountability can make a big difference.

Whereas agencies may divide their focus, consultants treat each client as a top priority.

7. Quality of Work

Winner: Equal

Agencies and consultants alike can deliver impressive CRO outcomes.

Agencies may provide access to specialist teams, although that structure can involve delegating work to junior staff members for development.

With consultants, the same person typically oversees all aspects of your CRO, offering a hands-on and consistent approach.

Final Score

  • Agency: 3
  • Consultant: 5

Conclusion

Both CRO agencies and consultants have their strengths.

While agencies bring extensive resources and a variety of skills, consultants may offer a more cost-effective, adaptable, and personalised approach.
