In one of the lessons of the Online Entrepreneur Certification I do remember Kyle briefly touching on the Fetch and Render function of Google Search Console, but I never gave it much importance (nor did I remember applying it to my posts) until @AussieJeff reminded me in one of his messages. So, all the credit to Jeff for this training!!
With this tutorial, I am going to attempt to clarify what Fetch and Rendering functions are in Google Search Console (I still prefer the old name Google Tool Webmaster, but what do you want to do about it!!) and why we should fetch and render our pages and posts regularly.
As I tried to understand what fetching and rendering content entailed, my biggest obstacle was to come to term with the techie language. The more experts and experience of you I hope will forgive my rather simplistic explanations.
