My AI employee

From 5 clicks to over 1,000: how Sebastian helped build kevinwelter.com.

Sebastian has been working for me since August 26, 2026, and there's a finished package for him in the community.

Sebastian is my AI employee for SEO, GEO and blogging. From August 27 to September 21, 2026, the two of us built kevinwelter.com in three stages: from 10 to 224 posts per language, German and English, with hub pages, an internal linking strategy and a measurement after every stage. He measures with real tools, writes in separate roles and checks; I proofread, answer his questions and approve. Nothing goes live without me.

The story: kevinwelter.com in three stages

On August 27, 2026, the website had 16 pages, 10 of them blog posts, and 5 clicks from Google search in August, all for my own name. What came next is documented in Sebastian's project folders, every number with its source. As of September 21, 2026.

The internal linking strategy is the part you can't see from outside. Every hub page links its posts, every post links its hub and two to four neighbours, and almost every post ends at the community, the Kubernetes posts at the book. That this doesn't run on its own showed in Sebastian's check on September 19, 2026: of 4,770 search queries, 205 pointed to more than one of my own pages, and when he pulled up the pages live, a strong overview page simply wasn't linking to the better target page. Findings like that go into the linking plan as tasks, not as assumptions.

What AI search makes of it, Sebastian measures separately: Microsoft Copilot cited kevinwelter.com 183 times in the three months through September 16, 2026, and the most-cited page isn't the one with the most Google clicks. Honesty cuts both ways: on September 18, 2026, an independent cross-check found factual errors in a delivery that Sebastian's own editing had missed. Since then, large deliveries get an independent cross-check, and every finding is verified against the primary source instead of accepted blindly.

Sebastian for your business

A different website and different topics, the same build: measure, write, link, remeasure.

Sebastian does not simply copy my keywords or my posts. You give him the website, business model, target market and access to the data that matters for your visibility.

How I use him

Build and measure kevinwelter.com

Sebastian combines the audit, keyword research, posts in two languages, hub structure and internal linking with remeasurement through Search Console, Bing and AI citations.

Adapted to you

Your website, your topics, your search goals

You define countries, languages, offers, important page types and available data sources. Sebastian turns them into a suitable measurement and writing setup instead of a generic SEO checklist.

What you change

  • Domain, countries and languages
  • Offers and search intents
  • Data access and measurement period
  • Audit, blog build-out or GEO focus

Other possible uses

  • Local business
  • Online store
  • Knowledge portal
  • Multilingual website

The process stays: Measure first, support every finding, write and check posts based on proven demand, put nothing live on his own and remeasure with the same setup after implementation.

What Sebastian can do, and with what

His own course in my community shows exactly this chain, from the first measurement through writing to the follow-up:

01

Write posts and optimize them for SEO

Posts in German and English following a guide and a fact sheet: search phrase from real Google suggestions, the answer in the first paragraph, a question block and sources. Checked by a test script and an editor in a separate role. Approval and go-live stay with me.

02

Plan hub structure and internal linking

A hub-and-spoke structure of hub pages and posts, a linking plan with incoming links per post, and a check of the real links after every release instead of only on paper.

03

Measure technical quality

Lighthouse and Unlighthouse for Core Web Vitals, load times and basic technical checks, free and with no sign-up.

04

Find broken links

linkinator for broken internal and external links across an entire website.

05

Crawl sites systematically

advertools for structured crawls and bulk analysis of robots.txt, sitemaps and meta data.

06

Render pages for real

Playwright CLI for screenshots and real page rendering, including where a simple crawl fails on JavaScript.

07

Evaluate field data

The PageSpeed Insights API for real-world field data instead of lab data alone.

08

Track search performance

Google Search Console and Bing Webmaster Tools, read-only, once a client grants access: search queries, clicks, impressions, indexing status.

09

Measure AI visibility

His own GEO baseline measurements: which pages AI search systems like Microsoft Copilot cite, and how often.

What he can't do, where I approve

He puts nothing live himself. Every post, every change to a live website, every URL submission or IndexNow request in someone else's account goes through my explicit approval case by case, even if he could technically make the change himself.

He's read-only in other people's accounts. He can read Google Search Console and Bing Webmaster Tools once access is granted, but he can't submit anything. For one client he had to withdraw an already-proposed measure because the Google access was read-only and restricted.

No invented numbers, no ranking guarantees. Every figure comes from a saved tool result in his own project folder.

His own editing isn't always enough. Large deliveries get an independent cross-check, because two checks from the same source are only one check. He learned that himself on September 18, 2026.

He follows crawl etiquette: on a client's shared hosting, at most one request every three to five seconds. An overly aggressive test run once caused a half-hour outage for a client, which he disclosed openly in the audit.

Trend topics without evidence, such as llms.txt as a supposed ranking lever, he flags as such instead of selling them.

Frequently asked questions about Sebastian

Can AI analyze my website for SEO?

Yes, with a fixed tool chain instead of guesswork: Lighthouse and PageSpeed Insights for the technical basics, linkinator for broken links, plus Search Console and Bing Webmaster Tools once access is granted. Sebastian delivers a project folder with raw data and an evidence-backed assessment for every finding, not an estimated number.

Can AI write blog posts that get found on Google?

Yes, if demand, structure and checking are right. For kevinwelter.com the topics came from real Google suggestions, every post follows a guide with the answer first, a question block and sources, and every post went through a test script, an editor in a separate role and my proofreading. After the build-out of September 7, 2026, Search Console showed twice as many clicks within a week. That's a measurement from this project, not a promise for another one.

What's the best SEO audit tool?

There's no single best tool, it's a chain: Lighthouse and Unlighthouse for technical checks, linkinator for links, advertools for structured crawls, plus Search Console and Bing Webmaster Tools for real click and query data. Only the combination gives a reliable assessment instead of one isolated number.

Can you do SEO yourself, without an agency?

Yes, free tools get you far: Lighthouse, linkinator, Playwright and PageSpeed Insights cost nothing and need no agency. What's usually missing isn't the tool, it's the fixed routine of measuring regularly, documenting findings with evidence, and actually re-measuring after a change instead of implementing it once and moving on.

How do I set up Google Search Console?

Add your domain or URL prefix in Google Search Console, verify ownership via a DNS record or an HTML file, then submit the sitemap URL. Sebastian then reads out search queries, clicks, impressions and indexing status, once he's been granted read-only access to the account. Submissions or account changes stay with me.

How does a website get cited by ChatGPT?

There's no reliable guarantee for that, only observations: Sebastian's own analysis shows Microsoft Copilot cited kevinwelter.com 183 times over three months, and that the most-cited page isn't the same one that gets the most Google clicks. AI citation frequency and Google ranking are two separate metrics, not a guarantee of either.
