SEO that gets implemented, not just recommended.

Most technical SEO is delivered as a document and dies in a developer’s backlog. I am the consultant and the developer. I read the Search Console data and the server logs, write the audit, and then make the changes in the theme, the templates and the server myself. Two SEO agencies use me white-label for exactly that, and the sites I own are where the method was tested first.

Technical SEO services, as a list

Technical SEO is everything between a page existing and Google ranking it: whether it is crawled, whether it is indexed, what the raw HTML actually says, how fast it renders, and whether the site’s structure sends authority to the pages that sell. Each of those is a thing I measure and then change.

  • Technical SEO audit and implementation: the same person finds the problem in Search Console and the access log and fixes it in the code
  • Indexation and crawl: robots, sitemaps, canonicals, pagination, filter and parameter URLs, redirect maps, crawl budget read from the raw server log
  • Rendering: what the server sends versus what JavaScript builds, and the server-side rendering, static generation or hybrid that fits the page type
  • Structured data: Product, Article, Organization, Breadcrumb and FAQ markup that validates and matches what the page shows
  • Core Web Vitals: scripts, images, fonts, server response, measured on real templates with field data rather than a lab score
  • Content structure and keyword research: which pages should exist, what each one targets, how they link - the architecture under the content
  • International and multistore SEO: hreflang, per-market URLs and localisation across languages and stores

An SEO consultant, an SEO freelancer, or an agency?

An agency gives you a team: account management, content production at volume, outreach, reporting. If that is what you need, hire one, and I work alongside two of them already. What an agency does not give you is the person who reads the log file, finds the rendering bug and ships the fix the same week, because that person sits in a developer’s backlog three handoffs away.

That person is what you get here, whether you call it a technical SEO consultant or an SEO freelancer. One contact, who diagnoses and implements, measures the result in Search Console per change, and tells you when the problem is not technical at all. I say no to the engagements where you would be better served by a content team, and I will point you to one.

Ecommerce SEO: where the revenue terms rank

On a store the pages that earn money are the category pages, and on every platform they ship weak: no copy, filters that multiply URLs, pagination and sorting that duplicate them, and product templates missing the structured data that earns a rich result. That is where most of my agency work lands, in Liquid on Shopify and in Smarty and Twig on PrestaShop, and the WooCommerce version is template and taxonomy work in PHP.

The platform pages linked below go into the specifics. The method is the same: Search Console and the access log first, the templates second, the measurement per change afterwards.

International SEO across 22 markets

The PrestaShop estate I run is 23 storefronts in 22 markets on one codebase, which makes hreflang, per-market URLs, duplicate handling across stores and localisation into daily work rather than a chapter in an audit. If you sell in several countries and your hreflang is “almost right” - which to Google is the same as wrong - this is familiar ground.

A technical SEO audit, and what happens after it

The audit starts with your Search Console data, a crawl of the live site and a week of raw access logs, so the findings describe what Googlebot does rather than what the sitemap claims. I keep a free access log viewer and an SEO analyzer on this site for exactly that first look.

Findings are ranked by what they cost you, not by how alarming they sound - a broken category template beats a missing alt attribute - and then implemented in that order, on a staging copy, through version control. Each change is dated and tracked against the affected pages’ impressions and position bands in the weeks that follow, so the report says what moved, not what was done. There is no composite score and no rate card; the scope depends on the site in front of me.

When the project is bigger

I lead every engagement. When the scope needs more than one pair of hands, I bring in people I have already delivered projects with, and you still deal with one person who is accountable for the result. It is not hiring a developer. It is hiring a delivery. Most work stays with me alone; the team is for the projects that need it.

Questions people ask first

Do you do content and link building as well?
Keyword research and content structure, yes - which pages should exist and what each targets. Editorial writing at volume and outreach I leave to your agency or writer and work alongside them. The technical base is what I own.
Which platforms do you work on?
Shopify, PrestaShop, WordPress and WooCommerce, and Next.js and other JavaScript frameworks, each with its own page on this site. The method transfers; the templates differ.
Can you work with our SEO agency?
That is the normal case. Two agencies already hand me their clients’ technical tickets white-label: they own the client and the strategy, I implement and report back to them.
How is progress measured?
Per change, in Search Console: the pages touched, the date, and what happened to their impressions, position bands and clicks afterwards. Not a rank-tracker screenshot and not a composite score.
Do you work in German?
Yes. Clients in Austria and Germany work with me in German, and the Ading and Blitzputz projects on this site were delivered entirely in German.
What does a technical SEO audit cost?
It depends on the size of the site and whether you want the findings implemented or handed over, so there is no price list here. Send the URL and you will get a straight answer.
