What is SEO? A clear explanation of how and why it works

SEO stands for search engine optimization. It is the work that makes your website appear higher in Google, so customers find you without you paying for every click. SEO comes down to three things: a site Google reads smoothly, content that genuinely helps your audience, and the trust of other sites. In this article you’ll learn what SEO exactly is, how it works, and why it is indispensable for B2B.

What does SEO mean?

SEO is the abbreviation of search engine optimization. It is everything you do to climb higher in Google’s unpaid, organic results. A concise definition of search engine optimization sums up the essence.

Those organic spots sit below the ads. You don’t pay per click for them. You earn them by being the best, most relevant page for a query. That’s exactly where the difference with SEO versus Google Ads lies: ads stop the moment your budget runs out, SEO keeps paying off.

How does SEO work?

Google has one goal: to show the best page for every query. It sends bots across the web that read pages and store them in a giant index. When someone searches for something, Google picks the best result from that index. Anyone who wants to grasp the basics will find plenty in Google’s SEO starter guide.

If you want to be that result, you have to work on three pillars. They don’t stand apart from each other but build on one another, from foundation to earned trust:

Pillar 1: technique

Google must be able to read your site smoothly. Fast pages, a clear structure, and pages that get indexed properly. This is the foundation. More on this in technical SEO.

Pillar 2: content

Technique opens the door, content wins the race. Google sees how people behave on your page.

Content ultimately ranks for one reason: because it is genuinely valuable to the user and engagement is high. People read it, stick around and come back.

So write for your visitor, not for Google. Give the answer someone is looking for quickly. How you do that, you’ll read in SEO copywriting.

Pillar 3: authority

Even strong content ranks slowly without trust behind it. You build that with backlinks: references from other trustworthy sites. One strong, earned link weighs more than a hundred bought ones.

In short: content covers the topic, links earn the right to rank, and your brand makes you the recognized choice. You need all three.

Why is SEO important for B2B?

Many B2B companies think they don’t need SEO. Yet almost every B2B company has to play the game. If you don’t, you become entirely dependent on paid advertising. The moment that budget stops, your traffic stops.

Your customers search on Google before they buy. If you’re not there, they find your competitor. SEO makes sure you get found at the moment someone is looking for a solution, with high purchase intent.

How long does SEO take?

Many people think SEO is always slow. That isn’t always true. How fast you see results depends on your competition, your industry and your niche. In a quiet market you often see movement faster than you’d think. In a crowded market it takes longer, but you build a lead that’s hard to catch up with.

What is the difference between SEO and GEO?

SEO makes sure you get found in Google. GEO, generative engine optimization, makes sure you get correctly mentioned by AI models like ChatGPT. More and more people search via AI instead of a classic search bar. The two reinforce each other: the same strong content and authority help you on both fronts.

How do you get started with SEO?

Never start by guessing. Start by knowing where you stand.

1. Do a free SEO check to quickly see your biggest problems.
2. Have a thorough SEO audit carried out for a complete picture and an action plan.
3. Work on the three pillars in the right order, as described in ranking higher on Google.
4. Unsure about doing it yourself or outsourcing? Read outsourcing SEO.

What is keyword research and why start with it?

Good SEO doesn’t begin with writing, but with knowing what your audience searches for. That is keyword research: mapping which words and questions your customers type in, and how often. Without that step you optimize for terms no one searches for.

More important than search volume is the search intent behind a term. Broadly, there are three types:

• Informational: someone is looking for an explanation, like “what is seo”. Here you win with strong knowledge articles.
• Commercial: someone is comparing, like “compare seo agencies”. Here service and comparison pages show their value.
• Transactional: someone is ready to buy or get in touch. This is where your service and contact pages belong.

So choose your keywords based on intent, not just on volume. For B2B, specific B2B keyword research is often more valuable: less search volume, but far higher purchase intent.

Which SEO tools do you need?

You don’t need an expensive suite to start. A few free basic tools already take you far, grouped by pillar. A more extensive overview can be found in our article on SEO tools.

• Measurement and indexing: Google Search Console (free) shows what you get found on and which pages Google indexes. Google Analytics 4 (free) shows what visitors do next.
• Technique: Google PageSpeed Insights (free) measures your loading speed. Screaming Frog crawls your site and finds technical errors, free up to 500 URLs. More on this in Screaming Frog website audit.
• Content and keywords: Google Keyword Planner gives search volumes. Paid tools like Ahrefs and SEMrush add competition and backlink data.
• WordPress: a plugin like Yoast or Rank Math helps you keep your metadata and structure in order.

The practical basics: metadata, internal links, mobile and E-E-A-T

Besides the three pillars, there are four practical elements that come into play on almost every page.

Optimize your metadata

Your title and meta description determine whether someone clicks on your result. The title and meta description are your billboard in the search results. Keep the meta description concise: on mobile, Google shows about 155 to 160 characters of it. Write it as a short, compelling summary with your keyword in it.

Use internal links wisely

Link from your pages to other relevant pages on your site. Internal links help Google understand your structure and distribute authority across your site. Use a descriptive anchor text instead of “click here”, so that both people and search engines know what’s behind the link.

Think mobile-first

Google indexes the mobile version of your site first. Because a large share of searches comes from a smartphone, a mobile-friendly website is not a bonus but the norm. Google measures loading speed and stability via the Core Web Vitals: slow pages cost you both visitors and positions.

Build up E-E-A-T

E-E-A-T stands for Experience, Expertise, Authoritativeness and Trustworthiness. It is the framework Google uses to assess whether your content is trustworthy. Concretely: show who the author is, demonstrate real experience and cases, and reference trustworthy sources. Since AI answers and AI Overviews play a bigger role, that trust weighs extra heavily, also for GEO.

What does SEO cost?

There is no fixed price, because SEO is tailor-made. Still, market figures give an indication. A freelancer typically charges around 60 to 130 euros per hour, an agency often 90 to 150 euros per hour. Ongoing engagements, depending on ambition and competition, usually sit between a few hundred and a few thousand euros per month.

What you exactly need depends on your starting position and goal. Whether you want to do it yourself or outsource, our comparison SEO costs: freelancer, agency or in-house helps. Unsure about the right party? Then read SEO freelancer or agency.

From SEO to more leads

SEO is not a goal in itself. The goal is more leads. More traffic alone is not enough if your site doesn’t convince visitors.

The fastest win often lies in a better conversion rate via conversion optimization. In the engagements we roll out for more leads, we often see a doubling to tripling of the number of enquiries.

That’s how a strong SEO approach at Gom Nederland produced 400% more daily visitors within 66 days.

Frequently asked questions about SEO

How long does it take before SEO produces results?

Count on the first movement after three to six months and on serious results in competitive markets after six to twelve months. In a quiet niche it often goes faster, in a crowded market longer. Anyone who promises a number 1 position within a few weeks can’t deliver on it.

Is SEO free?

You don’t pay per click like with ads, but SEO does cost time and work. Think of hours for technique, content and link building, and possibly the cost of an agency or freelancer. The organic clicks themselves are free, the work to earn them is not.

What is the difference between SEO and SEA (Google Ads)?

SEO focuses on the unpaid, organic results and keeps paying off after the work is done. SEA, or Google Ads, are paid ads that sit at the top as long as your budget runs and stop the moment you stop paying. The two complement each other well.

What is the difference between on-page and off-page SEO?

On-page SEO is everything you do on your own site: content, technique, metadata and internal links. Off-page SEO happens outside your site, mainly earning backlinks and brand mentions. You need both: on-page builds the base, off-page earns the trust.

What are backlinks and why do they count?

Backlinks are links from other websites to yours. Google sees them as recommendations: the more trustworthy sites refer to you, the more authority you build. One strong, earned link weighs more than a hundred bought ones.

Can I do SEO myself or is it better to outsource it?

You can perfectly lay the foundation yourself with free tools and the steps in this article. Outsourcing pays off once your market is competitive or you lack the time and expertise. In outsourcing SEO you’ll read when each choice fits best.

Does AI affect the way SEO works?

Yes. More and more people search via AI assistants instead of a classic search bar. As a result, GEO comes to stand alongside SEO: being correctly mentioned by AI models. The basics stay the same, because strong content and authority help you on both fronts.
