How to Choose an Online Advertising Agency

What an online advertising agency actually does

An online advertising agency plans, runs and improves paid campaigns on platforms such as search engines, social networks and display networks. The job covers more than pressing "publish" on an ad. It includes deciding which audiences to target, setting budgets and bids, writing ad copy, choosing or briefing visuals, setting up conversion tracking, and adjusting campaigns week by week based on what the numbers show.

Whether a business calls itself an online advertising company, firm or specialist, the work is largely the same. The differences are in size, how many people touch your account, and how much of the process they handle themselves. Before comparing providers, be clear about what you need: someone to build campaigns from scratch, someone to fix campaigns that aren't performing, or someone to take over day-to-day management.

Agency, freelance specialist or in-house: which fits your business

A freelance online advertising specialist can be a good fit for a small budget and a single platform. You usually talk directly to the person doing the work. The risk is capacity: holidays, illness or a full client list can slow things down.

An agency or firm typically brings more people and a broader skill set, for example copywriting, landing page advice and email follow-up alongside the ads themselves. That matters because ads rarely work on their own. A click is only useful if the page it lands on and the follow-up after it are good enough to turn a visitor into a customer.

Hiring in-house makes sense when ad spend is large and steady enough to justify a full-time salary, plus the tools and training that come with it. Many businesses start with an outside partner and only bring the work in-house once they know what works.

Questions to ask an online advertising agency before you hire

The answers to these questions tell you more than any portfolio slide. A capable provider will answer them plainly and without hesitation.

• Who will work on my account day to day, and how do I reach them?
• How quickly do you respond to questions or urgent issues?
• Will the ad accounts be set up in my name, and will I keep full access if we stop working together?
• How will you track conversions, such as calls, form submissions or sales, rather than just clicks?
• What do you need from me in the first month, and what will you deliver in that time?
• How often will I get a report, and what will it contain?
• How do you charge, and is the management fee separate from the ad spend?
• Is there a minimum contract length or notice period?
• How do you make sure campaigns follow platform policies and applicable advertising and privacy laws?
• What would you change first in my current campaigns, and why?

Red flags when choosing an online advertising company

Some warning signs show up early, often in the first sales conversation. Treat any of the following as a reason to ask more questions or walk away.

Guaranteed results are the most common one. No honest agency can promise a set number of leads or a first-page position, because results depend on your market, your offer, your budget and the competition. What an agency can commit to is a clear process, transparent reporting and steady work on improvement.

• Guarantees of specific rankings, lead numbers or returns before they've seen your data.
• Ad accounts created under the agency's name, so you lose your history and data if you leave.
• Vague answers about how the budget is split between ad spend and fees.
• Reports that only show impressions and clicks, with no link to leads or sales.
• Long lock-in contracts with no performance review points.
• Slow or unclear communication during the sales process, which rarely improves after you sign.
• Tactics that ignore platform rules or privacy and consumer protection laws, which can get accounts suspended.

How reporting from your ad agency should work

Reporting should answer one question: is the money spent on ads bringing in business? Clicks, impressions and click-through rates are useful for diagnosing problems, but they are not the result. A good report connects spend to the actions that matter to you, such as quote requests, calls, bookings or purchases.

Agree on the reporting rhythm at the start. Many businesses find a short monthly report plus a quick check-in works well, with more frequent updates during launches or tests. Each report should show what was spent, what it produced, how that compares to the previous period, and what will be changed next. The last part is often missing, and it's the most important. A report without next steps is just a record.

You should also have direct access to the ad platforms and your analytics at any time. Reports summarise the data; they shouldn't be the only way you can see it.

• Spend per platform and per campaign
• Conversions, cost per conversion and, where possible, revenue
• Comparison with the previous period and with the goals you agreed on
• What was tested and what was learned
• Planned changes for the next period

What the cost of an online advertising agency depends on

There are two separate costs: the ad spend you pay to the platforms, and the fee you pay for management. Keep them apart in every proposal you compare, so you know exactly how much reaches the ads.

Agencies commonly charge a flat monthly fee, a percentage of ad spend, an hourly rate, or a combination with a one-off setup fee. None of these is automatically better. What matters is that the fee matches the work involved and that you understand what's included.

The amount of work, and therefore the price, depends on several factors. We don't publish fixed prices because these vary a lot from one business to the next. Ask us for a quote and we'll explain what's included.

• Number of platforms and campaigns
• Whether campaigns are built from scratch or taken over
• How much ad copy and creative needs to be produced
• Tracking setup and landing page work
• Reporting frequency and level of detail
• Size of the monthly ad budget

How we work as your online advertising partner

We've spent many years helping businesses get results from online advertising, email marketing and copywriting. That combination matters: ads bring people in, copy persuades them, and email keeps them coming back. We look at all three when we advise on a campaign.

We respond quickly. If you have a question about a campaign or a sudden change in performance, you shouldn't have to wait days for an answer. We also follow best practices and the laws that apply to advertising and data, so your campaigns and accounts aren't put at risk by shortcuts.

Every engagement starts with a free consultation. We look at your goals, your current campaigns if you have them, and what a realistic next step would be. You'll leave the call with a clearer picture, whether or not you decide to work with us.

How to prepare for your first call with an agency

You'll get far more out of a first conversation if you come prepared. Know what a lead or sale is worth to your business, roughly what you can spend each month, and which results you'd count as success. If you've run ads before, have access to those accounts ready, even if the results were disappointing. Past data shows what has already been tried and saves time and money.

It also helps to bring any proposals you've received from other providers. Comparing them side by side, using the questions and red flags above, makes it easier to see which offer is clear and which leaves important things out.
