Online advertising is one of the most direct ways for businesses to get in front of potential customers. Whether you’re running a small local company or managing a larger brand, it can help you increase visibility, bring more people to your website, and, ultimately, generate sales.
The difficult part isn’t finding a place to advertise. It’s choosing where to spend your money.
Google Ads, Facebook, Instagram, YouTube, email marketing, SEO — there are plenty of options, and trying to use all of them at once rarely makes sense. A business selling professional services to other companies, for example, will probably need a very different mix of channels from an online shop selling consumer products.
So, where should you start?
We’ve helped dozens of businesses use online advertising to support their growth. In this guide, we’ll look at the main advertising channels, how they work, what affects online advertising cost, and what you should consider before investing your budget.

So, What Is Online Advertising?
Online advertising is a broad term for marketing activities used to reach potential customers through digital channels.
In practice, this might mean appearing at the top of Google when someone searches for a service, showing a Facebook or Instagram ad to people interested in a particular product, or reminding previous website visitors about a product they viewed but didn’t buy.
The objective isn’t simply to reach as many people as possible. What matters is reaching the right people — those who are genuinely likely to become customers. That’s ultimately what effective internet advertising should do.
Some of the best-known platforms for internet advertising include Google, Facebook, Instagram and YouTube. However, the channel itself is only part of the equation. Targeting, the message, the offer and what happens after someone clicks the ad can have just as much impact on the final result.
Good online advertising doesn’t simply generate traffic. It gives the right person a reason to take the next step.
Why Is Online Advertising Important for Business?
You’ve probably heard some version of the phrase, “If you’re not online, you don’t exist.”
It’s an exaggeration, but not by much.
People routinely use search engines, social media, and online reviews before deciding what to buy or which company to contact. Being visible during that decision-making process gives businesses an opportunity to reach customers who may never have discovered them otherwise.
Paid online advertising has one particularly useful advantage: it can generate visibility relatively quickly.
That speed comes at a price. Unlike organic channels, advertising usually stops bringing traffic once you stop paying for it. And if campaigns aren’t targeted or monitored properly, a surprisingly large part of the budget can disappear on clicks and impressions that never turn into enquiries or sales.
This is why online advertising shouldn’t be treated as simply “buying more traffic.”
For small and medium-sized businesses, starting with a modest budget can actually be useful. Instead of committing heavily from day one, you can test a channel, see how people respond and decide whether increasing the investment makes sense. If you’re unsure where to begin, we recommend testing the potential of online advertising with our help rather than spreading a limited budget across too many channels at once.
Main Types of Online Advertising
There isn’t one type of online advertising that works for every business. The right approach depends on what you’re selling, who you’re trying to reach, and how people normally choose a product or service like yours.
Some of the main channels worth considering are:
- Social media advertising — Facebook Ads and Instagram Ads, YouTube, TikTok, Pinterest, LinkedIn Ads and other platforms
- Content marketing and SEO — useful content designed to attract visitors through search engines
- Email marketing — newsletters, customer communication and automated email sequences
- Search engine marketing (SEM) — primarily paid search campaigns through Google Ads
- Display advertising — banners and other visual advertising across websites
- Mobile advertising — advertising delivered through smartphones and other mobile devices
Each has its place. Let’s look at them in more detail.
1. Social Media Advertising
Social media platforms give businesses much more than somewhere to publish posts.
Platforms such as Facebook, Instagram, LinkedIn, TikTok and YouTube allow advertisers to define audiences, test different messages and measure how people respond to a campaign.
This makes social media advertising particularly useful when the product benefits from visual presentation or when the target audience can be defined reasonably well by interests, demographics or behaviour.
It also gives businesses plenty of data to work with. You can compare different ads, see which creative generates engagement and track what users do after interacting with a campaign.
But engagement alone isn’t necessarily success.
An ad can receive plenty of likes or video views and still generate very few customers. The metric that matters depends on the actual business goal — whether that’s purchases, enquiries, bookings, leads or something else.
2. Content Marketing
Content marketing takes a different approach.
Instead of immediately asking someone to buy, it gives potential customers useful information that helps them understand a problem, compare solutions or make a decision.
That could mean articles, guides, case studies, videos or other resources related to the questions customers are already asking.
For example, someone searching for information about the cost of a particular service may not be ready to contact a provider yet. A useful article can introduce the business at exactly that stage and build trust before a sales conversation ever takes place.
SEO (search engine optimization) plays an important role here because well-optimized content can attract organic visitors through Google and other search engines.
The trade-off is time. Unlike paid advertising, where traffic can begin soon after a campaign launches, content marketing and SEO generally require consistent work before meaningful organic visibility develops.
3. Email Marketing: Newsletters and Automation
Email marketing is especially valuable when a business already has an audience — customers, subscribers or people who have previously shown interest.
Instead of paying every time you want to reach those people again, email gives you a direct communication channel.
Newsletters can be used to share useful content, offers and company updates, while automated emails can respond to specific actions taken by users. You can also explore our email marketing services if you want to build this into a broader marketing strategy.
Large e-commerce businesses such as Amazon are a familiar example. Their emails aren’t simply sent to everyone in exactly the same form. Messages can be connected to previous purchases, browsing behaviour and individual interests. Lithuanian e-commerce businesses such as Pigu.lt use similar principles.
The lesson isn’t that every company needs complicated automation. Email becomes much more useful when the message reflects what the recipient actually cares about.
4. Search Engine Marketing (SEM)
Search engine marketing helps businesses become visible when people are actively searching for particular products or services.
This is an important distinction.
Someone scrolling through social media may or may not be interested in buying something at that moment. Someone typing a specific service into Google is often much closer to making a decision.
SEM is frequently associated with PPC (pay-per-click) campaigns, with Google Ads being the most familiar example.
It’s also easy to confuse SEM with SEO.
SEO focuses on earning organic positions in search results. Paid search advertising allows businesses to pay for visibility for selected searches. Both can place a company in front of people using Google, but the way that visibility is achieved is very different.
Paid campaigns are commonly evaluated using metrics such as cost per click and cost per impression. Those figures are useful, but they shouldn’t be viewed in isolation.
A cheap click that never produces a customer isn’t necessarily better than an expensive click that regularly generates valuable enquiries.
5. Display Advertising
Display advertising uses visual formats such as banners, graphics, photographs and video to reach people while they browse other websites.
When someone clicks the ad, they’re usually taken to the advertiser’s website or a dedicated landing page.
This sounds simple, but placement matters.
Showing an attractive banner to thousands of people isn’t particularly valuable if those people have little interest in what you’re selling. The websites where ads appear, their position on the page and what users see after clicking can all affect performance.
This is why campaigns need to be monitored rather than simply launched and forgotten.
One particularly useful form of display advertising is remarketing.
Remarketing allows businesses to show ads to people who have already visited their website or, depending on the setup and available data, audiences based on existing contacts.
You’ve probably experienced this yourself: you look at a product online, leave the website and then notice the same brand appearing elsewhere.
Used carefully, remarketing can bring potential customers back when they’re still considering their options.
6. Mobile Advertising
Most people spend a significant amount of time using smartphones, so mobile devices naturally play an important role in digital marketing.
Mobile advertising can take several forms, including ads inside mobile apps, push notifications, SMS or MMS messages with links, and campaigns specifically optimized for mobile users.
One practical detail is easy to overlook: an advertisement designed on a desktop screen may perform very differently on a phone.
If the landing page loads slowly, buttons are difficult to tap, or a form requires too much effort to complete, paying for mobile traffic won’t solve the underlying problem.
Data protection also needs to be considered carefully, particularly when personal information is used for targeting or direct communication.
Advertising Built Around Your Audience
One of the easiest ways to waste an advertising budget is to start choosing platforms before understanding the customer.
Different buyers have different needs, habits, and reasons for making a decision. Depending on the business, useful audience characteristics might include:
- Gender
- Age
- Education
- Income
- Location
- Interests
Not every factor will be relevant. In many cases, only a few of them will actually influence the campaign.
The important question is simpler: who are you trying to reach, and where are those people most likely to pay attention?
Consider a local business that only serves customers in one city or region. Paying to reach people across the entire country would make little sense. A smaller campaign focused on the relevant area could produce better results while avoiding unnecessary spend.
The same principle applies to Google, Facebook and Instagram campaigns.
More reach isn’t automatically better. If half of the audience could never realistically become customers, you’re paying for visibility you don’t need.
Understanding your buyer makes it easier to choose the right channel, create a more relevant message and use the advertising budget more efficiently. That’s also one of the basic principles behind effective internet advertising: spend the budget where the relevant audience actually is.
How to Create Effective Online Advertising
An advertisement ultimately has one job: persuade a particular person to take action.
That applies to both B2C and B2B campaigns. Even when the buying process is long and involves several decision-makers, someone still needs a convincing reason to choose one company over another.
Most effective online advertisements rely on several basic elements:
1. Headline
The headline earns attention.
It should give people a reason to stop, read, or click — whether through a clear benefit, an interesting question, a problem they recognize, or something genuinely relevant to them.
A headline doesn’t have to be shocking to work. Often, clarity beats cleverness.
2. Subheadline
The subheadline gives you a little more room to explain the promise made in the headline.
It can clarify the offer, introduce an important detail, or give the reader another reason to continue.
3. Body Copy
This is where you explain the product or service in more detail.
Good body copy doesn’t simply list features. It helps the potential customer understand why the offer matters to them and what problem it solves.
4. Images
Visuals influence how people perceive an advertisement before they’ve read much of the text.
They can demonstrate the product, provide context, or simply help the message stand out. The important part is that the visual supports the offer rather than distracting from it.
5. Call to Action
Once you’ve attracted someone’s attention and explained the offer, they need to know what to do next.
That might be visiting a product page, booking a consultation, requesting a quote, or contacting the company.
A clear call to action removes unnecessary uncertainty. Don’t make users guess what the next step is.
How Much Does Online Advertising Cost?
This is one of the most common questions we hear from potential clients: how much does online advertising cost?
Unfortunately, there isn’t one useful number that applies to every business.
The cost of online advertising depends on what you’re trying to achieve and how the campaign needs to be built. Before estimating a realistic budget, it’s usually necessary to know:
- Which advertising channels will be used
- What services are required and for how long
- How many products or services are being promoted
- How many keywords or search phrases are being targeted
- How large and competitive the campaign needs to be
The pricing model can vary as well. Depending on the platform and campaign, advertisers may pay for clicks, impressions, or other actions.
Competition also affects the final cost.
If several businesses are competing aggressively for the same customers, gaining visibility will usually require a larger investment than in a less competitive market.
But focusing only on the cheapest possible click can be misleading.
Suppose one campaign generates clicks for €0.50, but almost nobody buys, while another costs €2 per click and consistently generates qualified enquiries. The second campaign is more expensive on paper, but it may be far more valuable to the business.
That’s why the better question isn’t simply, “How cheap can we advertise?”
It’s “What are we getting back from the money we’re spending?”
How Can We Help With Your Online Advertising?
A good online advertising strategy should fit the business rather than forcing the business into a standard campaign template.
When planning campaigns, we consider the client’s goals, budget, and the specifics of the business before deciding which channels and approaches make sense.
Sometimes that means starting small and testing one channel. In other cases, a broader campaign across several platforms may be justified.
We’ve worked with young businesses operating on limited advertising budgets as well as larger brands looking to improve the performance of their online advertising.
The aim is the same in both cases: create advertising that is measurable, realistic, and focused on reaching people who can actually become customers.
