What organic visibility changes for you

01
Your traffic keeps running when the ads stop.

Your traffic keeps running when the ads stop.

A well-ranked page brings in enquiries months after it was written. Your acquisition cost falls as the traffic climbs, instead of starting from zero again.

02
You capture buyers already searching.

Someone typing "Laravel developer Brussels" is not at the same stage as someone seeing an ad between two videos. Those visitors turn into meetings far more often.

Generative engines like ChatGPT answer by quoting a handful of sources. Being structured to be among them puts you ahead of competitors who have not even looked at the question yet.

What you get

Technical audit

Technical audit

Speed, indexing, URL structure, structured data, blocking errors. That is the layer that decides whether the rest of the work is worth anything.

Semantic analysis

Semantic analysis

Your real keywords, their volumes in Belgium and the intent behind each query. A French volume measured on France says nothing about your market.

Competitive analysis

Competitive analysis

What your competitors rank for and where the ground is free. Attacking a query already held by three large players is rarely the right start.

Content plan

Content plan

Pillar pages, articles, comparison pages, with a production order. You know what to write, in what order, and why.

Fixes applied

Fixes applied

I get my hands into the site, I do not deliver a list of recommendations for somebody else to execute. That is the advantage of a consultant who codes.

Monthly tracking

Monthly tracking

Positions, organic traffic, pages on the rise and presence in AI answers. A short report you read in five minutes.

This site ranks using the method I sell you. These articles are its raw material.

How an SEO and GEO engagement runs

Five steps. The first two are the diagnosis, because without it you optimise at random.

Be wary of offers under €500 per month. Below a certain budget, the volume of work produced is not enough to move positions.

Your questions about SEO and GEO

How much does SEO support cost at Numinam?

The audit is a finished deliverable, billed once. The retainer is a volume of days reserved every month: that volume is what determines how fast your positions move.

ServiceBudgetWhat it includes
SEO and GEO auditfrom €1,785 (3 days)Technical, semantic, competition, costed plan
Monthly retainerfrom €1,200 / monthFixes applied, optimisation, report
Retainer with contentfrom €2,500 / monthThe above, plus production and inbound links

Below €500 per month, the volume of work produced is not enough to move positions. An offer at that price funds an automated report at best.

How long before you see SEO results?

Faster than you usually hear on the technical side, slower on the content side. Here is what actually happens, month after month.

HorizonWhat you can expect
Weeks 1 to 4Technical fixes, pages finally indexed, speed restored
Months 2 to 3First positions on low-competition and local queries
Months 4 to 6Organic traffic visibly rising, first attributable enquiries
Months 6 to 12Positions on competitive queries, citations in AI answers

That calendar assumes regular production. Two months without content do not push the curve back by two months, they push it down.

What is the difference between SEO and GEO?

SEO targets a position in a list of results. GEO targets a citation in an answer written by an AI. The two overlap widely, but not completely.

SEOGEO
TargetGoogle, BingChatGPT, Perplexity, AI overviews
SignalsLinks, authority, relevance, speedFactual clarity, structure, consistency across sources
Content formatPages targeting an intentDirect answers, structured data, tables
MeasurementPositions and trafficCitation frequency on your typical queries

A site invisible on Google is also invisible in AI answers: the models lean heavily on what the engines already rank. GEO is therefore not a replacement, it is an extra layer.

How does Numinam measure the results of an SEO strategy?

With numbers that exist before the work starts, to avoid the report celebrating progress nobody can verify.

MetricToolWhat it tells you
Positions per keywordRank trackingWhere you stand on your target queries
Impressions and clicksGoogle Search ConsoleWhat Google already shows of you
Organic traffic per pageAnalyticsWhich pages are actually working
Enquiries attributed to organicForms and CRMThe only metric that pays your invoices
Citations in AI answersTypical queries replayedYour presence in generative engines

The last row is the one that counts. Traffic that doubles without a single extra enquiry signals a content or journey problem, not a success.

Do you need to work on SEO in Dutch for a Belgian market?

Only if you sell in Flanders. Otherwise the budget is better spent on depth in French: two half-worked languages are worth less than one well-held language.

When Dutch is justified, I start from the queries people actually type in Dutch rather than translating your French pages. Search intent differs from one language to the other, and a literal translation rarely ranks.

Freelance SEO consultant or SEO agency: which should you choose?

The question to ask is about execution: who is actually going to change your site, and how fast.

Freelance consultantSEO agency
Monthly costNo overhead to carryOverhead passed on
Technical fixesApplied directlyHanded to your developer
Content volumeLimited by one personHigh, several writers
Who you talk toThe person doing the workAn account manager
When it is the right callSME, site to fix, fast decisionsHigh content volumes, several markets

My advantage comes down to one thing: I fix the site myself. Most audit recommendations die because nobody implements them.

We already have content, does it all need rewriting?

Almost never. On an existing site, most of the quick wins come from pages already written that do not target the right intent, or that compete with each other on the same subject.

The audit sorts your pages into three piles: to optimise, to merge, to delete. Deleting pages often lifts the rest of the site.

Is SEO profitable compared to Google Ads?

The two do not play at the same moment. Ads buys visibility right now, SEO builds it and keeps it.

SEOGoogle Ads
Cost over timeAn investment that compoundsA spend that restarts every month
Time before results2 to 6 monthsImmediate
DurabilityTraffic stays after you stopTraffic stops with the budget
Control over volumeGradualAdjustable day by day

For an SME starting out, the healthiest combination is often Ads on a landing page while SEO builds up, then a gradual reduction of the advertising budget.
