The choice between a consultant and an agency comes down to a single question: do you lack the hours or the judgement? If somebody in your business can execute but is unsure what to do, a consultant who audits, sets the strategy and reviews monthly gives you senior expertise at a fraction of a retainer. If nobody has the time, advice alone produces a document and no change, and an agency is the right purchase.
What a consulting engagement should deliver
A written audit with prioritised findings, an account structure recommendation specific enough to implement, a conversion tracking plan, and an agreed monthly or quarterly review. Anything vaguer becomes an expensive conversation. Ask for a sample audit, with the client details removed, before engaging, since the quality of that document is what you are buying.
Consultants are useful precisely where agencies conflict
A consultant paid a fixed fee has no stake in your media budget rising, no reason to recommend the platforms they happen to manage, and no reluctance to tell you to spend less. That independence is the main argument for the model, and it is strongest when used to review an incumbent agency's work rather than to replace it.
Training the internal team is often the best value
Where you have someone capable, a consultant who teaches them the account, documents the routines and leaves a checklist produces capability that persists. This is usually cheaper than a year of management fees and it removes a dependency. Ask explicitly for training and documentation as deliverables rather than as a by-product.
Agree how the relationship continues
A monthly review of a defined length, with an agreed agenda and a written summary, keeps the value flowing without the cost of management. Set what happens between reviews: who they will answer a question from, and how quickly. Consulting relationships decay into nothing when the cadence is left informal.
Questions people ask about ppc advertising consultant
How are PPC consultants priced?
Day rates for audits and projects, and a monthly fee for ongoing advisory. Compare against an agency retainer including what you will pay internally to execute, because the consultant model assumes somebody in your business does the work.
Can a consultant manage the account too?
Many do, and at that point you are buying a one-person agency with the advantages and risks that implies: senior attention, no cover during holidays, limited capacity. Ask what happens when they are unavailable and whether anything is documented.
Is it worth hiring one to review our agency?
Often, yes, and it is one of the highest-return small purchases available. An independent audit of an incumbent's account either confirms the work is sound or identifies specific issues, and either outcome is worth the day rate.
What should we prepare before the engagement?
Access to the accounts and analytics, your own numbers on customer value and conversion rates, and a clear statement of what decision you want help with. Consultants waste the first day assembling those when the client has not, and you pay for that day.
