Technical SEO & Website Security

A website is only as good as its foundation.

Good design doesn't matter if your site is slow, insecure, or invisible to search engines. I look at what's underneath the surface — performance, structure, and security — and fix what's actually holding your site back.

What this looks like

Technical SEO and security aren't about chasing algorithm updates or adding a padlock icon — they're about the fundamentals: how fast your pages load, how cleanly your site is structured, and how well it's protected.

I audit what's actually happening under the hood, then fix the specific things that are costing you rankings, speed, or peace of mind.

What I can help with

What I can help with

01

Site Speed & Core Web Vitals

Faster loading on real phones: images, fonts, scripts and caching, measured before and after.

02

Technical SEO Audits

Indexing, canonical tags, sitemaps, redirects, structured data and the issues that keep pages out of search.

03

Security Hardening

Fewer ways in: updated dependencies, protected admin areas, rate limits and safe defaults.

04

SSL, Headers & Access Control

HTTPS everywhere, security headers such as HSTS and CSP, and the right access for the right people.

05

Search Engine Indexing & Structure

A structure search engines and AI assistants can read: sitemaps, structured data and llms.txt.

How I approach it

I don't guess at what's wrong.

First, I run a proper audit — performance, structure, security — and find out what's actually slowing you down or putting you at risk.

Then I fix the foundation first, before touching anything else.

Ongoing care

Keep it safe after launch.

A build is day one. A site only stays secure if it's kept up to date — patched, monitored, backed up. These are monthly plans that do exactly that, with a plain report each month of what was done.

Essentials

For a brochure or portfolio site.

from €39 / month

  • Monthly core, plugin & PHP updates
  • Off-site backups with restore tests
  • Uptime, SSL & file-integrity monitoring
  • Baseline hardening (WAF, login protection, headers)
  • Critical advisories patched in the monthly cycle

Priority

For higher-stakes, revenue-critical sites.

from €179 / month

  • Everything in Business
  • Daily backups + staging with rollback
  • Real-time alerts
  • Same-day patching of critical advisories
  • Quarterly security review call
  • Faster incident response

Prices are indicative, scoped to your site — no fixed package. No scare tactics: a clear monthly report, and honest advice on what you don't need.

Questions

Asked before every project like this.

What does a technical SEO audit include?

Speed and Core Web Vitals on mobile, indexing and crawl issues, redirects and canonical tags, sitemaps and robots.txt, structured data and security headers. You get a list of what's wrong, in order of impact, and what fixing each item involves.

Can you fix the issues, not just report them?

Yes. The audit is the starting point: I can fix the issues on the site directly, or work with whoever maintains it.

Do you guarantee rankings?

No, and nobody honestly can. What I can do is remove the technical reasons a site loads slowly, isn't indexed properly or isn't trusted, and measure the result.
