Coming from an international background, I have always been interested in search performance across multiple countries.
As Growth Marketer at Authoritas I have been able to study the performance of the SERPs including images, videos, featured snippets and local pack across 11 different countries. I have put together a presentation that highlights some of the main differences as well as how you can implement featured snippets on your own site with out needing to code..
