We all know it happens but we will never have access to it. The Google Algorithm is the set of criteria on which a website is ranked. The search engine results are structured with this list of determining factors. Imagine a new page being published and indexed instantly- it will have already passed through this this algorithm and subsequently positioned in the SERP’s accordingly.
