Here's how I'm different from other SEO experts

Directly from me to you

Remember that time you hired an "SEO expert" and ended up talking to their intern? Yeah, that doesn't happen here.

When you work with me, you get... well, me. No junior managers. Just pure SEO expertise straight from the source.

Battle-hardened

My SEO experience spans the full spectrum: from sites with virtually no indexed pages to those with over 250 million.

I have optimized websites that receive over 4 million daily clicks and have served for 5 years as the Head of SEO for a leading tech company in Europe, with monthly organic visits exceeding 500 million.

Whatever your SEO challenge, I’ve likely encountered and resolved it.

Globally recognized

I have notably identified and reported critical bugs in the Google crawler.

My SEO methods have been featured at Europe's top conferences. But don't worry, I won't bore you with technical jargon (unless you're into that sort of thing).
‍
Trusted internationally, I predominantly secure projects through referrals, thanks to my reliable and superior outcomes.
