About Stradiji: We Help Brands Get Found on Google and in AI Answers

Stradiji is an SEO and generative engine optimization (GEO) consultancy founded in Istanbul in 2010 by Mert Erkal. We help enterprise brands show up, get recommended and convert in Google and in AI answers from ChatGPT, Gemini, Perplexity and Google AI Overviews.

We’re a small, senior team. You know exactly who works on your account from day one.

How we started

Mert Erkal graduated from Istanbul Technical University’s naval architecture school in 1996 and spent a decade at Maersk Line Turkey. Logistics taught him the rule we still work by: you can’t improve a process you don’t measure.

He started in SEO in 2009 and founded Stradiji in 2010. Since then, we’ve worked with enterprise brands in banking, consumer electronics, publishing, healthcare and more.

The job has shifted. Buyers now start vendor research by asking AI. So we’ve built GEO on top of our SEO work: we measure why AI answers skip your brand, find the cause and sequence the fixes.

What we believe

Measure first

We don’t start with guesses. We know where your site stands before the first call.

Proof, not promises

No one can guarantee AI visibility. We guarantee the measurement, the root cause and the re-test.

SEO is the foundation of GEO

AI doesn’t recommend sites with weak SEO. We run both in one plan.

You keep the know-how

Your team or your developers ship the changes. We write the specs and verify. When we’re done, the knowledge stays with you.

Where we work

We’re based in Istanbul and work remotely with brands in the U.S., the U.K., Australia and Turkey, in English and Turkish. We also train in-house teams on SEO, GEO and AI.

Every week, we share what changed in search and AI, and what happened when we tested it, in SEOs Diners Club and on YouTube.
