Contractor Marketing Agency Pricing: Retainers, Packages and Hidden Fees

Two contractor marketing agencies can quote $2,000 a month and deliver completely different value. One spends most of it on your ads; the other keeps most of it. One gives you full ownership of your accounts; the other keeps your website if you leave.

Understanding contractor marketing agency pricing helps you compare proposals fairly and avoid surprises. This guide explains the common pricing models, what's usually included and the hidden fees to watch for.

1. Monthly Retainer

A fixed monthly fee for a defined scope of work, such as SEO, social media or ongoing marketing management.

• Pros: predictable cost, ongoing attention.
• Cons: value depends entirely on what's actually delivered.

Retainers are the most common model in SEO. Ahrefs' survey of 439 SEO professionals found that 78.2% charge monthly retainers, with agencies averaging about $3,209 per month. SE Ranking's 2025 survey similarly found monthly retainers to be the most preferred model.

2. Percentage of Ad Spend

The agency charges a percentage of what you spend on advertising, commonly cited at around 10% to 20%, usually with a minimum fee.

• Pros: scales with campaign size.
• Cons: can create an incentive to increase spending, whether or not it's profitable.

3. Flat Management Fee

A fixed monthly fee to manage ad campaigns, regardless of spend.

• Pros: predictable, no incentive to inflate spend.
• Cons: may not scale well for very large or very small budgets.

4. Hybrid

A base fee plus a percentage of spend above a certain level, or a base fee plus performance bonuses.

5. Project-Based

A one-time fee for defined projects, such as a website build, SEO audit or brand refresh.

6. Pay-Per-Lead or Performance-Based

The agency charges per lead or per outcome.

• Pros: aligns cost with results.
• Cons: definitions matter. What counts as a "lead"? Are leads exclusive? Who owns the ads and data?

7. Packages

Bundled services at tiered prices, such as starter, growth and premium tiers.

• Pros: easy to understand.
• Cons: may include services you don't need and miss ones you do.

Whatever the model, a proposal should clearly state:

• Deliverables: what work is done each month.
• Channels managed: Google Ads, Local Services Ads, Meta, SEO and so on.
• Ad spend vs. fees: exactly how much goes to platforms and how much to the agency.
• Reporting: frequency and metrics.
• Communication: meetings and response times.
• Tracking: call tracking, conversion tracking and CRM integration.

Ad Spend Markups

Some agencies bill ad spend through their own accounts and add an undisclosed markup. Ask: Will I see actual ad spend in my own accounts? Is there any markup?

Setup and Onboarding Fees

Common and sometimes reasonable, but they should be clearly defined.

Website Ownership and "Rented" Websites

Some agencies include a website in a monthly package but keep ownership. Cancel, and you lose the site. Ask: Do I own the domain, website files and content?

Tracking Number Ownership

If the agency's call tracking numbers appear on your ads, directories and website, what happens when you leave? Ask: Can I keep or port the numbers?

Ad Account Ownership

Your Google Ads, Analytics and Business Profile should be in your name, with the agency as a user. Otherwise, you may lose your history.

Long Contracts Without Exit Terms

Long contracts aren't always bad, but they should include clear deliverables and reasonable termination terms.

Add-On Charges

Extra fees for landing pages, ad creative, reporting or "additional channels" can add up. Ask for a complete list.

Auto-Renewals and Price Increases

A fair price is one where:

• The work delivered is clearly defined.
• You own your marketing assets.
• Results are measured in leads and jobs, not just traffic.
• Your cost per signed job is profitable.

Is percentage-of-spend pricing bad?

Not necessarily, but make sure spending decisions are based on profitable results, not on increasing the agency's fee.

Are pay-per-lead agencies a good deal?

They can be if leads are exclusive, well-defined and you own the assets. Read the terms carefully.

Should I sign a long-term contract?

Only with clear deliverables, transparent pricing and reasonable exit terms.
