Fundamentals of SEO

SEO, or search engine optimization, is the process of optimizing a website to rank higher on search engine results pages (SERPs). It involves understanding how search engines such as Google and Bing work, and tailoring your content to meet their algorithms.

What Is SEO?

SEO (Search Engine Optimisation) is the process of optimizing a website’s technical configuration, content relevancy, and link popularity so that its pages become more easily findable, relevant, and popular in response to user search queries, and, as a result, search engines rank them higher.

SEO can be broken down into on-page SEO, which focuses on optimizing content and HTML source code, and off-page SEO, which involves building backlinks and increasing domain authority.

Understanding SERPs

Search engine results pages (SERPs) display the list of websites in response to a user query. Understanding SERPs is crucial as it affects how users find your website. SERPs typically consist of organic search results, paid ads, and other features like featured snippets and local packs.

Organic SEO focuses on ranking within the unpaid results. The goal is to secure a position on the first page, as most users do not go beyond the initial results. On Google, factors like relevance, quality, and user experience are key to ranking well. Regularly analyzing SERP features and adapting strategies can help improve your site’s visibility and traffic.


To excel in Search Engine Optimization (SEO), one must understand a range of essential terms and advanced concepts, from basic elements like ‘backlinks’ and ‘keyword density’ to intricate ideas such as ‘E-A-A-T’ (Experience, Expertise, Authoritativeness, Trustworthiness). Key to this journey is focusing on crucial aspects like wisely chosen keywords, high-quality content, mobile optimization, and a seamless user experience (UX). Given the frequent changes in search engine algorithms, staying informed and adaptable is imperative for maintaining and enhancing your website’s visibility, recognizing that successful SEO is an evolving, iterative process.
