AI in advertising is quickly changing how companies create and manage their campaigns. In this article, we look at when it makes sense to manage advertising yourself with the help of AI agents, and when it is better to entrust it to a freelance specialist, an in-house employee or an advertising agency. The short answer: AI tools such as Google Ask Advisor, TikTok Symphony Agent or Meta’s AI solutions can write ad copy, generate visual ideas, analyse data and automate repetitive tasks, but they act as assistants – goals, priorities and final decisions still have to be made by a person. For a small business with a modest budget and simple campaigns, AI and your own time may be enough; for managing a single advertising channel, a freelancer; for a constant, heavy workload, an in-house specialist; and when several channels are used, a strategy is needed and faster results are expected, an agency. At the end of the article, you will find a comparison table of all options and answers to the most frequently asked questions.

Artificial intelligence is rapidly becoming part of how advertising is created and managed. On Google, Meta, TikTok and other advertising platforms, AI already helps build and run campaigns. AI can not only write ad copy or generate an image, but also analyse data, suggest optimisations and automate a large share of the work. So practically every company faces a key question: is it still worth entrusting advertising to a specialist if some processes can be handled in-house? There are several scenarios to choose from – use AI, hire a freelance specialist, have someone in-house, or work with an advertising agency. How do these options differ, and what should you consider before making a decision?

What Really Lies Behind Advertising That Works?

Good advertising does not start with an attractive ad or well-written copy. First, you need to know clearly what it should achieve, who it is for and what exactly you can offer the customer. Then you decide which channel is worth being present in, how much budget to allocate and how to measure whether the chosen direction has paid off. Campaign results are not the final point of reference either – based on the data, you need to make decisions and, where necessary, change what is not working.

AI can help with a large share of these tasks, but it works as an assistant that suggests possible solutions, not as a decision-maker that independently determines which one is best for a particular business. For example, it can generate dozens of ad copy variations, but a person still has to choose the most suitable one, assess how well it fits the business goals and decide whether it is worth using. If you have enough competence and experience, you can make these decisions yourself, using AI as a helper. Before deciding who to entrust your advertising to, it is worth assessing not only what AI can do, but also your own ability to critically evaluate its suggestions.

How Much Advertising Work Can AI Do Today?

AI in advertising can already do much more than write a few ad variations. It helps create headlines and copy, generate visual ideas, analyse audiences and results, find optimisation opportunities and automate repetitive tasks. Some platforms go even further. For example, Google offers Ask Advisor – an AI agent that can draw on Google Ads and Analytics data, provide recommendations, help build campaigns and analyse their results.

The agent principle itself matters here. A simple AI tool usually performs one specific task, while an agent can combine several actions into one process. Even so, the answers an agent provides are not always detailed or accurate enough – sometimes they are rather superficial. To get a quality result, you need to know how to formulate the task properly, provide additional context when needed and evaluate the suggestions very critically. The better you understand advertising processes and the data being analysed, the easier it is to spot shortcomings and make well-founded decisions.

When Can You Manage Advertising Yourself with AI Agents?

Not every company needs to hire an advertising specialist right away. AI agents make it possible to take over part of campaign management in-house, but this requires not only a willingness to try new tools, but also an understanding of how advertising itself works.

This option may suit you when:

there are few advertising campaigns and they are not complex;
someone in the company can dedicate time to advertising;
you want to learn to use AI tools and understand the key advertising metrics;
the advertising budget is small and the company can experiment on its own.

Main advantages:

lower external service costs;
more direct control over campaigns;
some repetitive work can be done faster.

However, consider the other side too:

what is usually missing is not only AI skills, but also advertising management experience;
you need to be able to critically assess AI suggestions and understand advertising metrics;
automated actions still need to be monitored;
poorly managed campaigns can waste the advertising budget.

If a person does not understand what the advertising is meant to achieve, AI will not solve the problem – it can only spend the budget faster. It is important not only to know the principles of advertising, but also to understand how the advertising platforms you use and their reports work. Results shown in different data sources may not match, so you need to know how to evaluate them and which data to rely on when making decisions. AI suggestions depend on the information it is given, so inaccurate or incomplete data can also lead to poor recommendations.

When Is It Worth Bringing in a Freelance Advertising Specialist?

When a company does not want to dive into advertising management itself, but does not yet need a dedicated employee or a full agency, a freelance advertising specialist can be a great “stopover”. This option lets you get professional help when you need it, without committing to long-term cooperation.

What makes this option attractive?

The company does not need to learn all the principles of advertising management;
you can benefit from the specialist’s existing experience;
there is no need to keep a permanent employee;
the specialist can be engaged for a specific project or period.

What should you pay attention to?

Without enough advertising knowledge, it can be hard to objectively assess a specialist’s competence, so it is very important to look into their previous work, experience and results achieved;
one person will not always have all the necessary knowledge, especially when working across several advertising platforms;
the services cost money, so it is important to assess whether they will pay off.

Even an experienced advertising specialist will not necessarily be the best choice for every business. Before starting to work together, it is important to understand what problem needs solving and what actions the company really needs. In one case, it may be worth investing in Facebook or TikTok ads; in another, it may be better to first fix the marketing measurement system or eliminate technical website errors. If the wrong tools are chosen or the work is done in the wrong order, even a competent specialist’s services may not deliver the expected results.

When Is It Worth Having an In-House Advertising Specialist?

When advertising becomes an ongoing part of the company’s operations and the number of campaigns and tasks grows, it makes sense to have a dedicated in-house specialist. In this case, advertising is not just a one-off project – it needs to be continuously monitored, analysed and adapted to changes in the business.

How is an in-house specialist useful?

They are constantly involved in advertising processes;
they know the company, its products and customers well;
they can react quickly to changes;
all accumulated knowledge and experience stay within the company.

What challenges might you face?

Keeping an employee may cost more than the services of an external specialist;
it can be difficult to find a person with the right competence;
one specialist’s experience may be limited to certain areas of advertising, so a broader perspective and new solutions may be lacking;
with technologies and advertising platforms changing rapidly, it is hard to keep up with new developments and acquire all the necessary skills;
the costs of training, searching for new solutions and experimenting have to be covered by the company.

If one person is expected to manage Google, Meta and TikTok advertising, handle creative work, analyse data and also shape the strategy, the problem may not be a lack of skills, but too broad a responsibility for one person.

When Should You Choose an Advertising Agency?

When a company’s advertising becomes complex enough, AI tools or a single specialist may no longer be sufficient. An agency can be a rational choice when you need to align different advertising channels, strategy, creative work and data analysis. The company can benefit from the experience of various specialists, established work processes, automations and technologies that would require additional investment to build independently. In addition, staff, administrative and technology costs are shared among several clients.

When can an agency be useful?

Several advertising channels are used;
campaigns are complex;
an advertising strategy is needed;
various competencies are lacking within the company;
there is no marketing team;
a larger budget is allocated to advertising;
experience gained across different business sectors and a broader view of advertising solutions are needed;
you want to benefit from the skills and technologies of various specialists without investing in a separate in-house team.

An agency team often has experience working with companies from different industries and solving a variety of advertising problems. This makes it possible to draw on accumulated knowledge and, in some cases, find the right solutions faster.

What should you pay attention to?

Services may cost more than hiring a single specialist;
it is important to find out how the work is organised and what tasks and responsibilities the agency takes on;
the company has less direct control over advertising management;
smooth cooperation with the agency is important for good results.

When choosing an agency, it is also worth reading more detailed advice on how to assess its experience, specialisation and reliability. You can read more in the article: How to Choose a Digital Marketing Agency?

Can AI and an Advertising Specialist Work Together?

Artificial intelligence does not necessarily have to replace an advertising specialist – it can become a convenient tool in their work. The technology can analyse data, generate ideas, create different ad variations and automate repetitive tasks, while a person sets the goals, assesses the business context and makes the final decisions.

This division of work is already visible on advertising platforms. TikTok Symphony Agent helps move from an ad concept to video creation, while a person can adjust the result. Meta is also expanding the use of AI for campaign optimisation and creative work. These examples show that AI can take over part of the tasks, but technology alone is not enough – it also matters who coordinates the entire marketing process.

When different specialists and AI tools work together, you need someone who sets priorities, assigns responsibilities and ensures that all actions help achieve shared business goals. This is covered in more detail in the article: When Does a Company Need a Digital Marketing Manager?

Which Advertising Solution Is Best for Your Company?

Artificial intelligence makes it possible to do more advertising work yourself, but simply having a tool is not enough. The more complex the campaigns, the larger the budgets and the higher the cost of mistakes, the more important human expertise becomes. When choosing, let yourself be guided not by what seems most modern, but by the company’s real needs, existing knowledge and capabilities.

To make the decision easier, the main differences are summarised in the table below:

Option	Pros	Cons	When does it fit?
AI agents + do-it-yourself advertising	Lower costs, automation, control	Requires learning and supervision, low quality, low chance of success	For small businesses and craftspeople, when advertising is simple and budgets are very small
Freelance specialist	Expertise, flexibility	Dependence on one person, potentially narrower expertise, average experience	When you need management in one area, e.g. Google Ads or Facebook Ads, without a permanent employee
In-house specialist	Constant involvement, knowledge of the company	Salary and additional costs covered by the organisation itself: recruitment, selection, training, practical experiments, administrative expenses; limited experience and knowledge “in a bubble”	When there is a constant, high volume of advertising work – enough for one or more full-time positions – and a dedicated, always-available specialist is needed
Agency	A team, diverse competencies and experience, internal and proven know-how, technology processes: automations, reporting structures, extensive practical experience. Better value for money	Higher price, less direct control, personalisation for the client	When you need comprehensive advertising management, experience and expertise, and want faster results at lower cost

FAQ

Can AI completely replace an advertising specialist?

No. AI can take over part of the advertising creation, analysis and optimisation work, but a person is still essential for strategic decisions and evaluating results.

Can a small business manage its own advertising with AI?

Yes, if the campaigns are not complex, only a few channels are used and there is someone in the company who can dedicate time to managing the advertising.

What can AI do in an advertising campaign?

AI can help create ad copy and visual ideas, analyse data, find optimisation opportunities and automate some repetitive tasks.

What can’t AI offer you in advertising campaigns?

AI cannot understand what exactly your business needs. It can suggest a variety of solutions, but a person has to assess which of them would be most useful and which new technologies are worth trying.

When should you choose an advertising agency rather than a freelancer?

An agency is worth choosing when several advertising channels are used, campaigns are complex, strategy, creative work and data analysis need to be aligned, and the company lacks a range of competencies. A freelance specialist is a better fit when you need to manage a single area, such as Google Ads or Facebook Ads.

When is it worth having an in-house advertising specialist?

When there is a constant, high volume of advertising work – at least one full-time position’s worth – and you need someone who continuously monitors campaigns and reacts quickly to changes. However, also consider the additional costs: recruitment, selection, training, and the risk that one person’s experience will cover only part of the required areas.
