About
An SEO team that learned to code. Not the other way around.
The story
SM4B has done search optimisation since 2012. For ten years, we optimised hundreds of sites built by others. We knew exactly what was wrong: code too heavy, CMSes too slow, developers who had never opened a performance report.
So we did what every frustrated SEO should do: we started building the sites ourselves. With the fastest framework on the market.
Astro4B is the result: SM4B's SEO expertise, put to work building sites designed to perform from day one.

Our philosophy
Every technical decision serves a business goal.
Every technical decision we make — from the framework to the CMS to the hosting — answers one simple question: does it help your business? If the answer is no, we don't do it.

Four offices. And remote everywhere.
