SEO
Search Engine Optimisation
Indexing, keywords, Schema, internal links and domain authority.
Limitation alone: generates traffic, but not necessarily customers.

INTERACTIVE TOOL What does your Lighthouse
What does your Lighthouse
score really tell you?
Adjust a lab score. The tool explains its category, limitations and the next useful measurement, without inventing a Google ranking or conversion rate.

Lighthouse category
Needs improvement
This result describes this lab test, with its configuration and precise point in time.
What it does not measure
To be measured
Rankings, conversions and field Core Web Vitals cannot be inferred from this score alone.
SXO assessment
Needs optimisation
Repeat the test, check the detailed audits and compare against available field data.
Methodological limitation
Lighthouse helps diagnose a page. Business results require their own baseline, reliable events and an observation period.
The categories shown are those of the Lighthouse Performance score. Field Core Web Vitals thresholds follow a different method, at the 75th percentile.
The concept
Three disciplines, one offer.
SXO unifies what most agencies sell separately. No more silos or blame between providers.
The visual guide
Be found, be understood, make action possible
One connected journey
-
SEO
Connect searches to the pages that answer them.
-
Conversion
Examine the promise, evidence and steps towards action.
-
Performance and UX
Make the journey responsive, stable and accessible.
CRO
Conversion Rate Optimisation
A/B tests, heatmaps, user journeys, microcopy and forms.
Limitation alone: optimises existing traffic; it does not generate it.
Perf + UX
Performance + User Experience
Core Web Vitals, accessibility, mobile-first and emotional design.
Limitation alone: a fast, attractive website can still struggle to sell.
SXO = SEO + CRO + Perf + UX, integrated from the wireframe stage.
Not a post-delivery checklist. A structural approach from the first line of code.

Frequently asked questions
All about SXO.
What is SXO, and how does it differ from traditional SEO?
SXO connects SEO, conversion optimisation, performance and user experience from the design stage. It guarantees neither traffic nor conversions. The difference is in the method: objectives, architecture, journeys and measurement are scoped together instead of being added after launch.
How much does a professional SXO website cost in Brussels?
The stated prices depend on the number of pages, languages, integrations, measurement plan and follow-up. The proposal details the scope. No generic conversion rate or traffic figure is used to justify the budget.
Why should Lighthouse and Core Web Vitals be kept distinct?
Lighthouse is a lab audit under simulated conditions. Field Core Web Vitals describe real users’ experience at the 75th percentile when sufficient data is available. A Lighthouse score cannot determine a Google ranking, a percentile of sessions or a conversion rate.
Is SXO compatible with WordPress?
Yes. The result depends on the theme, plugins, hosting, media and third-party scripts. A custom theme can help, but no technology alone guarantees a score or field Core Web Vitals.
How soon will we see the first SEO results?
No universal timeframe can be given. Indexing, competition, demand, domain history and offer quality influence results. The proposal separates controllable deliverables from observed effects.
Is SXO suited to AI engines (ChatGPT, Perplexity, Claude)?
The same foundations remain useful: accessible pages, original content, consistent information and reliable sources. Google states that no llms.txt file or special markup is required for its generative features. Documented crawlers can be allowed or blocked, without any guarantee of citation.
Can you guarantee my Google rankings?
No. Kanexio commits to the deliverables, checks and acceptance criteria written in the proposal. Rankings, citations, conversions and revenue depend on external factors and are not guaranteed.
