When considering PPC services for your business, one decision you will have to make on the way is choosing between a PPC 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 drive profitable leads and revenue through paid advertising, their approach, structure, and relationship with clients differ significantly.

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

2. Cost-Effectiveness

Winner: Consultant

While agency quotes can be cost-effective, they often build in expenses for physical premises, leadership staff, and admin personnel.

With consultants, you bypass all of that. You’re investing in their knowledge, not a corporate hierarchy.

Consequently, PPC consultants typically prove the more economical option.

3. Resources

Winner: Agency

With multiple team members on hand, agencies are naturally geared towards supporting larger projects.

They’re able to work on several campaign elements in parallel by leveraging their broader resource base.

If your requirements are extensive, involving several moving parts, an agency could be the right choice.

4. Adaptability

Winner: Consultant

By design, agencies often depend on structured systems and standardised ways of working to coordinate their teams.

Although individual team members might be flexible, updates to your account setup or approach can be slower to roll out.

A consultant, in contrast, can personalise their service and shift direction rapidly when your priorities change.

That responsiveness can be a real asset in the constantly evolving digital space.

For instance, if a new opportunity arises mid-campaign, a consultant can usually respond immediately, while agencies may be delayed by processes and multiple layers of sign-off.

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

PPC 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 PPC 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

Consultants and agencies both have the ability to deliver strong PPC campaigns.

Agencies may draw on a mix of experts, but that often involves delegating tasks to more junior staff as part of their development.

Consultants, however, usually manage the full project themselves, which means your strategy benefits from a more personal, detail-oriented approach.

Final Score

  • Agency: 3
  • Consultant: 5
