Online Advertising SEA

Online advertising via SEA (Search Engine Advertising) involves placing paid ads on search engines like Google, where you pay per click. Your ad appears at the top or bottom of the search results when someone searches for a keyword you’ve chosen. The difference from organic SEO is that you’re immediately visible as soon as your campaign goes live, but you pay for each visit. For small and medium-sized businesses, SEA is a way to quickly drive qualified traffic to your website, especially for new products, seasonal promotions, or competitive markets.

How does online SEA advertising work in practice?

You start by choosing the keywords you want to advertise on. Next, you write an ad copy with a headline, description, and URL. In Google Ads, you set a daily budget and a maximum cost-per-click (CPC). Google determines whether your ad appears based on your bid, the quality of your ad, and the relevance of your landing page. This is called Ad Rank. The higher your Ad Rank, the more frequently and higher up your ad will be displayed. You only pay when someone clicks on your ad. For example, an ecommerce store selling gardening supplies can advertise for the search term “buy garden furniture” and pay between 0.50 and 2.50 euros per click, depending on the competition.

Why online advertising (SEA) emerged and why it’s important today

SEA emerged in the early 2000s when Google launched AdWords as an alternative to banner ads. Advertisers wanted to pay only for results, not for impressions. The pay-per-click model proved effective because it was measurable and scalable. Today, SEA is crucial for companies that want to gain visibility quickly in a competitive market. Organic SEO takes months, while SEA delivers visitors within a day. Especially in sectors with high search volumes and strong competition—such as insurance, recruitment, or ecommerce—SEA is often the fastest route to new customers.

What online advertising (SEA) delivers for small and medium-sized businesses

With SEA, you gain direct control over your visibility. You can choose which keywords you appear for, where you advertise, and at what time of day. You can see in real time how many clicks you’re getting, what they cost, and how many conversions result from them. For example, a B2B service provider can choose to advertise only on weekdays between 9 a.m. and 5 p.m., targeting decision-makers in the Randstad. This makes SEA predictable and scalable. At Monkey Vision , we help small and medium-sized businesses set up an SEO and SEA strategy that combines organic growth with targeted paid campaigns. This allows you to build brand awareness while generating immediate leads.

Online advertising (SEA) is not a one-size-fits-all solution. How you use it depends on your business goals, your profit margin, and the stage your company is in. Below are four specific applications we often see among small and medium-sized businesses, plus a decision-making framework to help you determine when SEA is—or isn’t—the right choice.

Product launches and seasonal promotions

If you’re launching a new product or running a short-term promotion, you want to gain visibility quickly. SEA is ideal here because you can go live within a day. For example: a sports nutrition ecommerce store launches a new protein shake and aims to sell 500 units in two weeks. Through SEA, you advertise on search terms like “buy protein shake” and “whey protein sale.” You direct visitors to a landing page featuring a limited-time discount. By testing ad copy and adjusting your bidding strategy, you optimize the campaign on a daily basis. The result: predictable sales within a tight timeframe. This also works for seasonal businesses such as garden centers, caterers, or ski rental companies.

Lead generation for B2B services

B2B companies with a longer sales cycle use SEA to generate qualified leads. Think of an HR consulting firm advertising “developing an absenteeism policy” or an IT service provider targeting “ISO 27001 certification.” Your ad addresses a specific need and leads to a white paper, a quick scan, or an intake interview. By using audience targeting, you exclude consumers and focus on companies with 10 or more employees. The cost per lead is often between 30 and 150 euros, depending on the niche. A well-designed campaign generates 10 to 20 qualified leads per month, which you can then follow up on via your CRM.

Competition based on brand name and comparison keywords

If your competitors rank highly in organic search results, you can still maintain visibility through SEA. You can advertise using a competitor’s brand name or comparison keywords such as “alternative to [brand]” or “cheaper than [competitor].” This is a tactic that works particularly well in markets with little differentiation, such as software tools, insurance, or energy providers. Note: advertising on someone else’s brand name is allowed, but you may not use the brand name in your ad copy without permission. Here’s an example: a local bike shop advertises using “Gazelle dealer Nijmegen ” even though a competitor dominates that term organically. This way, you can still capture a portion of the search traffic.

Remarketing to previous website visitors

Not every visitor converts immediately. With SEA remarketing, you can show ads to people who have already visited your website but didn’t take any action. This works through the Google Display Network or via search ads using RLSA (Remarketing Lists for Search Ads). Here’s an example: someone views a web design quote page but doesn’t fill out a form. A week later, that same person searches for “website design Nijmegen ” and sees your ad with a recognizable message. The likelihood of conversion is now much higher because brand awareness has already been established. At Monkey Vision , we often combine this with web design projects in which we optimize landing pages for both organic and paid traffic.

When is online advertising (SEA) the right choice, and when is it not?

SEA makes sense if you can measure a clear conversion, have sufficient margin to cover the cost-per-click, and need quick results. It works less well with low margins, unclear target audiences, or products that nobody is actively searching for. A common mistake we see: companies launch a campaign without a clear landing page or without conversion tracking. That’s just throwing money away. Choose SEA if you have a clear offer, a strong story, and the capacity to follow up on leads immediately. Choose organic SEO if you’re in it for the long haul and want to build sustainable visibility without ongoing advertising costs.
