well... there is an extremely large number of international online marketers and SEO's in public... there also exist tons and extreme masses of content around all the topic(s) - just as much opposition and bullshit.
the passionate way BILL analyzes algorithmic changes and correlations, underpins them with well-founded information and publishes them in the form of actual "added value" / content has significantly influenced my personal approach for more that 15 years now. furthermore it has influenced the way I learn/act + how I handle and communicate inside customer projects and relationships.
at this point I would like to express my best thanks for that 🙏, especially for your immense invest of TIME⏱️ . I really hope there will be much much more to follow 🚀
thank you - take care & good recovery to you
