SEO specialist: what they do and how to choose the right one

An SEO specialist makes sure your website gets found by people searching for what you sell, and that those visitors actually take action. That is not a trick or a button in a tool: it is the interplay of technique, content, authority and measurement. A good specialist masters all four, knows where the biggest gains sit in your situation, and can explain why they do something and what it is worth.

This page is deliberately two things at once: an honest description of the craft for anyone doing it themselves, and a practical guide for anyone looking to hire someone. Looking for the paid counterpart? Read what an SEA specialist does.

What an SEO specialist actually does

SEO stands for search engine optimization: improving your visibility in the unpaid search results. The work falls into four areas, which can block each other in that order. A page that isn't indexed can be written as well as you like — it still won't show up.

Translated into a working week, that looks like: mapping search queries and intent, deciding which page should answer which question, writing or rewriting those pages, tidying up internal links and structure, spotting technical errors in templates, reviewing new features before they go live, and reviewing clicks and revenue per topic each month instead of individual rankings.

What an SEO specialist doesn't do: guarantee a first-place ranking, or promise results within a month. Google publishes its Search Essentials and SEO starter guide openly, and states there that nobody can guarantee a ranking. Anyone who does is selling something else.

Why an SEO specialist adds value

Organic search has one property other channels don't: you don't pay per click. That makes the work cumulative. A page that ranks well keeps generating traffic without the budget growing along with it. The trade-off is that it works more slowly and you can't switch it on and off like ads.

In practice, a specialist tends to add value in four ways:

• Capturing demand that already exists. People are searching for your service or product. If you don't appear in the results, that demand goes to someone else. That isn't growth you create — it's growth you're currently missing out on.
• Lowering cost per lead. Every organic lead that doesn't touch the ad budget lowers your average acquisition cost. That is often the strongest argument in a business case: not more revenue, but the same revenue more cheaply.
• Preventing mistakes. Migrations, redesigns and new templates are the most common causes of a sudden drop in visibility. A specialist who reviews things before launch is usually cheaper than the recovery afterwards.
• Giving direction to content. Search data literally tells you which words your market uses to think about its problem. That's useful for your whole communication, not just your website.

That effect isn't free or immediate. For an existing site, expect several months before you see anything at the revenue level, and longer for a new site or a competitive market.

What a good SEO process looks like

The order isn't a matter of taste — it follows from dependencies. Without reliable measurement, you won't know after three months what worked. Without indexing and a decent structure, new content has less effect. And without genuine quality, technique and links won't get you a ranking that sticks.

What knowledge an SEO specialist really needs

Don't ask for a list of tools — ask what someone does with them. This is what the craft demands in practice:

Two more things rarely appear in a job posting but matter just as much: being able to explain things to non-specialists, and being willing to say something won't work. In practice that's the difference between a specialist and an operator.

The questions to ask before you hire someone

These five questions say more than a portfolio:

1. "What would you investigate first with us, and why?" A good specialist wants to know first whether your measurement is accurate and whether your pages are even indexed. Anyone who jumps straight to a keyword list hasn't looked yet.
2. "Tell me about something you did that didn't work." Every serious project contains failed assumptions. Anyone without one hasn't measured anything.
3. "What figures do you report on?" The answer should include clicks, conversions and revenue or leads per topic. Rankings alone, or a "visibility score", isn't enough.
4. "What do you need from us?" Expect: access, decisions, and time from a developer or content writer. Anyone who says "nothing, just leave it to me" is underestimating the work.
5. "What happens if we stop?" The answer should be: the work stays in place, and you have documentation and access. If visibility collapses the moment someone leaves, it wasn't SEO.

Warning signs: guarantees on rankings, a fixed monthly fee without a plan, tools that "build backlinks", no access to your own data, and reports that reach the same conclusion every month.

What an SEO specialist costs

There is no rate card and no reliable national figures, so this is what we see in the market rather than a norm. As an employee, an SEO specialist in the Netherlands is a role that grows with experience from junior level, through an independently working mid-level professional, to someone who combines strategy and technique; expect that last category to cost more than a generalist marketer, and the talent pool for that group to be tight. Freelance and interim rates run higher per hour than a permanent role, and that makes sense: you're paying for availability without recruitment risk.

The more useful question isn't the rate but the sums around it: what is a lead or order worth to you, how much search demand exists in your market, and what does that same lead currently cost you through advertising? Once you know those three, choosing between a few hours a month and a dedicated specialist becomes a calculation instead of a gut feeling. KPIs and targets explains how to set those numbers up, and measurement in online marketing explains how to keep them reliable.

How we help: in-house people, freelance and interim

Brandable has worked since 2010 with a core team and a network of specialists we know personally and have worked with before. For SEO that means three ways of working together, and we'll tell you honestly which one fits.

• Our own team. We handle SEO as part of the whole: website, content and campaigns together. That works well when technique, copy and visibility all need attention at the same time — exactly the situation where a single standalone specialist keeps waiting on others.
• A freelance SEO specialist. For a defined assignment or a fixed day a week. You're not hiring a profile from a platform, but someone whose work we know, with us as backup if more than one person is needed.
• An interim specialist. When a role needs to be covered temporarily: a vacancy, leave, or a period that also needs direction, not just execution.
• Strengthening your own people. If you already have someone, coaching or a workshop is often more useful than outsourcing. That's about prioritising and about what not to do.

In every case the same principle applies: accounts, data and delivered work belong to you, and the way of working is documented so it keeps functioning once we're gone.

Where SEO usually goes wrong

We see four causes most often, and none of them is a lack of keywords:

• The site can't handle it. Slow templates, pages without a clear purpose, or a structure where important pages sink too deep. See building a good website and PageSpeed Insights.
• Content gets produced instead of written. Many pages that each say half the story rank worse than one page that fully answers the question. Demonstrable expertise does more here than volume.
• The measurement is wrong. Without reliable conversion tracking, every discussion about effect is a discussion about opinions.
• Nobody owns it. SEO is partly ongoing work. If nobody has it in their week, it slips back after one quarter.
