Many business owners know they need help with online marketing but are not sure what an agency would actually do for them. The term covers a wide range of firms, from SEO specialists to full-service teams that run every channel. This guide explains the services agencies offer, the different agency types, how a typical engagement runs, and how pricing works. It is written for Canadian businesses weighing whether to hire one.
| What does a digital marketing agency do? A digital marketing agency plans, builds and manages a business’s online marketing. Typical work includes search engine optimization, paid advertising, social media, email, content and website improvements, plus tracking and reporting. The agency sets a strategy based on your goals, runs the campaigns, measures results and adjusts. Some agencies cover every channel. Others specialize in one or two. |
A digital marketing agency is an outside company that a business hires to attract and convert customers through online channels. Instead of building a full marketing department, the business pays the agency for strategy, execution and reporting. The agency usually works across search engines, social platforms, email, websites and online ads.
The main difference from a traditional advertising agency is the focus on measurable, online activity. Almost every action can be tracked. You can see which search terms bring visitors, which ads lead to calls and which emails get opened. A good agency uses that data to decide where your budget should go next.
Agencies range from one or two consultants to large teams with specialists for each channel. Semrush data for Canada, October 2026, shows about 90 monthly searches for “what does a marketing agency do” and about 70 for “what is a digital marketing agency”.
Most agencies offer some mix of the services below. A full-service firm handles all of them. A specialist may only do one.
SEO work improves how your website shows up in unpaid Google results. It covers technical fixes, keyword research, page content and local listings. An overview of the process is on the search engine optimization service page.
Agencies set up and manage ads on Google, Meta (Facebook and Instagram), LinkedIn and other platforms. This includes targeting, ad copy, bidding, landing pages and budget control.
Many agencies plan and publish social posts, write blog articles and run email newsletters. Content work often supports SEO, because new pages give search engines more to rank.
Traffic only helps if the site turns visitors into leads or sales. Agencies often redesign pages, improve speed and test forms. Some also handle full web design projects.
Agencies set up tracking such as Google Analytics, call tracking and conversion events. They then report on what each channel produced.
Agencies are not all built the same way. Knowing the main types makes it easier to compare proposals.
| Agency type | What it does | Best fit |
|---|---|---|
| Full-service | Runs strategy and most channels under one roof | Businesses that want one partner for everything |
| Specialist | Focuses on one channel, such as SEO or paid search | Businesses with an in-house team that needs one skill |
| Local | Works mainly with businesses in one city or region | Companies that sell to a local market and want face-to-face meetings |
| Industry-focused | Serves one sector, such as law firms or trades | Businesses that value sector experience |
| Branding and digital hybrid | Combines brand identity work with digital campaigns | Companies launching or repositioning a brand |
None of these types is better by default. A specialist may go deeper on one channel. A full-service team can connect channels so that ads, SEO and email share one plan. The right choice depends on your goals, your budget and the skills you already have in-house.
Most engagements follow a similar pattern, even if each agency names the stages differently.
The discovery and audit steps matter more than they look. A plan built without real data about your customers tends to rely on guesswork. If an agency skips straight to a package price without asking about your business, treat that as a warning sign.
Once setup is done, the work becomes a cycle of execution and improvement. A typical month might include the following tasks.
Your role does not disappear. Agencies need fast feedback, approvals and access to people who know the product. They also need to hear which leads turned into sales. Without that information, an agency can only optimize for clicks or form fills, which may not match revenue.
Good reports explain what changed, why it changed and what the agency will do next. A report full of charts with no plain explanation is harder to act on. Ask for a short written summary at the top of each report.
Agencies use a handful of pricing models. Many combine two of them. The table below explains how each works. Dollar amounts are left out on purpose, because rates vary widely between agencies, cities and scopes.
| Pricing model | How it works | Watch for |
|---|---|---|
| Monthly retainer | A fixed fee each month for an agreed scope of ongoing work | A clear list of what the retainer includes |
| Project fee | One price for a defined project, such as a website or audit | How changes outside the scope are billed |
| Hourly rate | You pay for time used, often tracked in blocks | Regular time reports so costs do not drift |
| Percentage of ad spend | The management fee rises or falls with your ad budget | Whether the incentive favours higher spend over better results |
| Performance-based | Part of the fee depends on leads or sales | How results are defined and tracked |
Ask every agency to put its model in writing, along with the contract length, notice period and who owns the accounts and assets. Those terms affect the real cost as much as the monthly number does.
Agency fees are only part of the total. If you run ads, the ad spend goes to the platform, not the agency. On Google Ads, for example, you are charged when someone clicks your ad, and the Google Ads Help page on bidding explains that you often pay less than your maximum bid. Your budget sets a spending limit for each campaign.
Click prices vary a lot by industry. Semrush data for Canada, October 2026, estimates an average cost per click of $18.18 CAD for “plumber vancouver” and $4.80 CAD for “accountant vancouver”. These are estimates. Actual costs depend on the auction, ad quality and targeting.
The main factors that shape agency fees include:
Hiring an agency is one of three common options. Each has trade-offs.
An in-house marketer knows your business deeply and is available every day. One person rarely has expert skills in every channel, though. You also carry salary, benefits, software and training costs.
A freelancer is often flexible and affordable for a single skill. Capacity is limited. If that person is sick or busy, work stops.
An agency gives you access to several specialists and their tools under one contract. You get less day-to-day presence than an employee. You also share the team’s attention with other clients.
Many businesses mix these options. A common setup is an in-house coordinator who owns the brand and the calendar, with an agency handling SEO and paid ads. Businesses in the Lower Mainland that want a local team can compare that approach with what a digital marketing agency in Vancouver offers. The goal is to cover the skills you lack without paying twice for the ones you have.
Most disappointing agency relationships share a few avoidable causes.
Before signing, read the full contract. Check the cancellation terms, the minimum term and what happens to content and creative when the contract ends. A companion guide on how to choose a digital marketing agency in Vancouver includes a checklist of questions to ask.
Short answers to common questions about what digital marketing agencies do.
A traditional marketing agency may handle print, radio, TV, events and public relations. A digital marketing agency focuses on online channels such as search, social media, email, websites and online ads. Many agencies now do both, so read the service list rather than relying on the name.
Many do. Some build full sites, while others only improve landing pages and conversion paths on an existing site. If you need a new site, ask to see live examples and check who will host and maintain it after launch. If you want site work and campaigns handled by one team, ask whether an online marketing service covers both.
It depends on the channel. Paid ads produce traffic and data as soon as they launch, though tuning them takes time. SEO and content usually build more slowly because search engines need time to crawl and rank new work. Ask each agency for a realistic timeline per channel.
Usually not. The management fee pays the agency for its work. The ad spend is paid to Google, Meta or another platform, often charged directly to your own card on your own account. Confirm this in writing so you know the true total cost.
Many agencies work with small businesses on a narrow scope, such as local SEO or one ad channel. Starting with one channel and a clear goal keeps costs controlled. You can add channels once the first one shows measurable results.
A useful report shows the key results against the agreed goal, the work completed, what changed since last month and the plan for next month. It should explain the numbers in plain language. Leads and sales matter more than impressions or follower counts.
A digital marketing agency plans, runs and measures your online marketing so you do not have to build every skill in-house. Services range from SEO and paid ads to content, email and website work. Pricing usually follows a retainer, project, hourly, ad spend percentage or performance model, and ad spend is separate. Pick the agency type that fills your real gaps, agree on one clear goal, and keep ownership of your accounts.
