Sometimes it's complex to fix something once you took one step into the wrong direction. With technical SEO, one wrong move could cost a lot and get a lot of your work down the drain. SEO expert Bartosz Góralewicz has been helping clients avoid that mistake since 2011 when he founded Elephate with his friend, Wojciech Mazur. Together, they've been assisting clients with SEO and content marketing services by helping them understand their market and competitors, making the best data-driven decision, and providing a better value for users and search engines. Bartosz specifically tackled the key problem of JavaScript SEO or JavaScript in general and some potential issues when you start using JavaScript. He also touches on biohacking, mobile-first indexing, pre-rendering, Chrome 59 which is the first headless Chrome, and many other stuff you should check into if you want to get ahead in the SEO game.
