How to choose a PPC agency in 2026

In short. A PPC agency plans, builds and runs your paid advertising across Google Ads, Microsoft Advertising, Meta and Amazon, measured on the revenue that spend returns. A good one gives you a named team, clean tracking, full ownership of your accounts and honest reporting on cost per acquisition. Choose on how they measure success, how they price and how clearly they communicate, and avoid anyone who guarantees results, hides the data or locks you into a long contract.

What a PPC agency does

PPC stands for pay per click, the model where you pay only when someone clicks your ad. A PPC agency runs that advertising end to end so your spend works harder than it would in house, and the remit is broader than most people expect.

• Strategy and structure. Deciding which channels to run, how to structure accounts and how budget should follow return.
• Keywords and audiences. Choosing the searches and audiences worth paying for, and the ones to exclude.
• Creative and copy. Writing ads and building assets that earn the click and the sale.
• Bidding and optimisation. Managing bids, budgets and automation so cost per acquisition stays healthy.
• Tracking and reporting. Setting up clean measurement and reporting on revenue, not vanity metrics.

This is the work we run every day inside paid media, across search, shopping and social as one system.

What good looks like

The best PPC agencies share a few habits. They obsess over measurement, because a channel you cannot measure is a channel you cannot improve. They report in the language of the business, cost per acquisition and revenue, rather than impressions and clicks. They treat your budget as if it were their own, moving spend toward whatever returns. And they give you a real named team you can reach, not a rotating cast of managers, with the thinking behind every change kept visible.

Questions to ask before you sign

The right questions surface how an agency really works long before the contract does.

• Who runs my account day to day? You want a named person, not a pool.
• How do you measure success? The answer should be revenue and cost per acquisition, not clicks.
• Do I own the accounts and data? You should own every ad account, pixel and conversion record.
• How do you track conversions? Look for clean, server side tracking, not guesswork.
• How often will we talk? Regular reporting and a clear point of contact matter.
• What happens if I leave? A confident agency lets you walk with everything you own.

Pricing models explained

PPC agencies price in three common ways, and each shapes behaviour.

• Flat monthly retainer. A fixed fee for the work. This is usually the cleanest model because the agency has no incentive to inflate your spend.
• Percentage of ad spend. The fee rises with your budget. Simple, but it can quietly reward spending more rather than earning more.
• Performance based. A fee tied to results. It aligns incentives when the targets are honest, though it needs clear rules on what counts as a result.

Whatever the model, the fee should reflect the complexity of the account and the skill managing it, not simply the size of the media budget.

Red flags to avoid

Some warning signs are consistent across the industry.

• Guaranteed rankings or guaranteed results. No one can promise the auction.
• Long lock in contracts that trap you rather than earn your stay.
• Refusing to let you own your own accounts and data.
• Reporting on impressions and clicks while staying quiet on revenue.
• No named contact, and slow or vague answers to direct questions.

How Google, Microsoft, Meta and Amazon fit together

The best results come from treating channels as one plan rather than four silos, because each does a different job. Google Ads and Microsoft Advertising capture demand people already have the moment they search, and Microsoft also carries paid placement into ChatGPT Ads and Copilot. Meta creates demand, putting your brand in front of people before they think to search. Amazon captures buyers at the point of purchase. A capable agency runs these together with shared tracking and budget that follows return, and that plan increasingly includes TikTok Shop too.

Key takeaways

• A PPC agency plans, builds and runs your paid ads across Google, Microsoft, Meta and Amazon, measured on revenue.
• Good agencies give you a named team, clean tracking, full account ownership and honest reporting.
• Ask about ownership, measurement, communication and what happens if you leave.
• A flat retainer keeps incentives honest better than a percentage of spend.
• Avoid guaranteed results, long lock ins and any agency that hides the data.

FAQ

What does a PPC agency do?

A PPC agency plans, builds, runs and optimises paid advertising across channels such as Google Ads, Microsoft Advertising, Meta and Amazon. The work spans strategy, account structure, keywords and audiences, creative, bidding, tracking and reporting, all aimed at turning ad spend into measurable revenue.

How much does a PPC agency cost?

Most PPC agencies charge a flat monthly retainer, a percentage of ad spend, or a performance based fee. A flat retainer is usually the cleanest because it keeps the agency focused on results rather than on spending more of your budget, and the fee should reflect the complexity of the account, not only the media spend.

What questions should I ask a PPC agency?

Ask who runs your account day to day, how they measure success, whether you own the accounts and data, how they track conversions, how often they report, and what happens if you leave. Clear answers on ownership, measurement and communication separate a strong agency from a weak one.

What are the red flags when choosing a PPC agency?

Watch for guaranteed results, long lock in contracts, agencies that will not let you own your accounts, vanity metrics instead of revenue, and no clear named contact. These signal an agency optimising for its own retention rather than your growth.
