In-House vs Agency Google Ads Management: Which Is Right for You?

Should You Manage Google Ads Yourself or Hire an Agency?

This is one of the most common questions we hear from business owners spending £2,000 or more per month on Google Ads. The answer depends on your budget, your team, and how much complexity your campaigns involve.

Having worked with hundreds of businesses that have tried both approaches, here is an honest breakdown of when each option works best.

What In-House Google Ads Management Looks Like

Managing Google Ads in-house means someone on your team (often the business owner, marketing manager, or a dedicated PPC hire) handles everything: keyword research, ad copy, bid adjustments, landing pages, tracking, and reporting.

Pros of In-House

• Deep business knowledge: No one understands your customers, products, and margins better than your own team
• Speed: No waiting for agency response times. Changes happen immediately
• Full control: You own the strategy and execution entirely
• No management fees: You pay the ad spend and the salary, nothing on top

Cons of In-House

• Skill gap: Google Ads is complex. A marketing generalist rarely matches a specialist
• No cross-industry insight: An in-house team only sees your data. Agencies see patterns across dozens of accounts
• Tool costs: Bid management, competitor analysis, and reporting tools add up (£500-2,000/month)
• Single point of failure: If your PPC person leaves, your campaigns suffer immediately

What Agency Google Ads Management Looks Like

An agency manages your Google Ads on your behalf. You pay a management fee (typically 10-20% of ad spend, or a flat monthly fee) on top of your advertising budget.

Pros of Agency

• Specialist expertise: Agencies live and breathe Google Ads every day across multiple accounts
• Cross-industry insights: What works in one industry often transfers to another
• Tools included: Most agencies absorb the cost of premium tools in their fee
• Continuity: If someone leaves the agency, another specialist picks up your account
• Accountability: Clear reporting and performance benchmarks

Cons of Agency

• Management fees: An additional cost on top of ad spend
• Less business context: Agencies need time to learn your business deeply
• Variable quality: Not all agencies are equal. Some over-promise and under-deliver
• Communication lag: Changes may take 24-48 hours depending on the agency

The Real Cost Comparison

Business owners often compare agency fees to zero, as if managing ads yourself is free. It is not. Your time has a value. If you spend 10 hours per month managing ads and your time is worth £100/hour, that is £1,000 per month in hidden cost, often producing worse results than a specialist would.

A dedicated PPC hire costs £35,000-55,000 per year in salary alone, before tools, training, and management time. Most agencies charge £1,000-3,000 per month, making them significantly cheaper until your ad spend exceeds £30,000-50,000 per month.

When to Manage In-House

• Your monthly ad spend exceeds £50,000 and justifies a full-time specialist
• You already have an experienced PPC professional on your team
• Your campaigns are simple (one product, one location, one campaign type)

When to Hire an Agency

• Your monthly ad spend is between £2,000 and £50,000
• You do not have specialist PPC expertise on your team
• You want to focus on running your business, not learning Google Ads
• You need someone accountable for performance

What to Look for in a Google Ads Agency

If you decide an agency is right for you, look for these things:

• Transparent reporting with access to your own Google Ads account
• No long-term contracts (confidence in their work means they do not need to lock you in)
• Experience in your industry or similar industries
• Clear communication about strategy, not just tactics
• They ask about your business goals and margins, not just your budget
