What is SEO?

Welcome to Week 1 of our 8-week SEO course! In this week's chapter, we will be introducing the concept of SEO, why it's important, the different types of SEO, and current trends and best practices.

Let's start with the basics: What is SEO? SEO stands for Search Engine Optimization. It is the practice of optimizing your website to rank higher in search engine results pages (SERPs). The goal of SEO is to increase the quantity and quality of organic traffic to your website. Organic traffic refers to visitors who come to your site through unpaid search results, as opposed to paid advertising.

Why is SEO important?

Why is SEO important? Simply put, it can make or break your online presence. If your website is not optimized for search engines, you could be missing out on valuable traffic, leads, and revenue. With more and more people turning to search engines to find information, products, and services, it's crucial to have a strong SEO strategy in place.

If you are looking to order some catering services for your business meeting. You go on google and search for something like “Best/top catering near me” and you get bunch of results. How accurate do you think those results are? As Google being the most popular search engine platform out there, they try to provide the best results. But it might not always be accurate or the results that users are looking for. As there are so many different metrics to consider if one business/service is better than the other. For instance, the top result for your search query might be worse in customer service than the 5th result, but because of their popularity or brand value they tend to appear on first page or top results. As a business owner, who is dominant in their market in terms of customer service or quality assurance, you would want to appear on top results. In most cases, you would need SEO to achieve that. With everything becoming digital, physical advertisings are less popular than ever. To efficiently deliver your message to your target audience online, any type of adjustments that you do to your current business practices is part of SEO (Search Engine Optimization).

How Google Search Works

During the crawling stage, Google's web crawlers explore the internet to discover new and updated pages. The crawlers follow links from known pages and also rely on submitted sitemaps. The program responsible for fetching pages is called Googlebot, which uses an algorithmic process to determine which sites to crawl and how often. However, Googlebot may not crawl all discovered pages due to various factors such as site owner restrictions or accessibility limitations.

After crawling, the indexing stage begins, where Google analyzes the content of the pages. This includes processing and analyzing text, key content tags, attributes, images, videos, and more. Google also determines the canonical page, which is the representative page from a group of similar pages. Signals about the canonical page and its contents, such as language, location, and usability, are collected and stored in the Google index. However, not every processed page is guaranteed to be indexed, and indexing depends on factors like content quality and metadata.

Finally, during the serving search results stage, when a user enters a query, Google searches its index for matching pages and returns the most relevant and high-quality results. Relevancy is determined by numerous factors, including user location, language, and device. The search results may vary based on the query, and Google's algorithms programmatically rank pages without accepting payment for higher rankings.

There are several SEO practices that have become outdated or are no longer used due to changes in search engine algorithms and best practices. Here are a few examples:
Keyword Stuffing The practice of overusing keywords on a webpage to manipulate search engine rankings is no longer effective and can result in penalties from search engines. Google began penalizing keyword stuffing in 2012 with the Penguin algorithm update.
Exact match domains (EMDs) EMDs, which are domain names that exactly match a keyword or phrase, used to be a common tactic for boosting search rankings. However, Google devalued EMDs in 2012 with the Exact Match Domain update.
Article spinning The practice of creating multiple versions of an article by swapping out words and phrases is no longer effective and can be considered spammy. Search engines can now detect spun content and penalize websites that use it.
Link exchanges The practice of exchanging links with other websites solely for the purpose of increasing backlinks is no longer effective and can be considered manipulative. Google has stated that link exchanges should be avoided and that websites should focus on creating high-quality content that naturally attracts backlinks.
Google's E-E-A-T Concept

One of google's popular SEO concept is known as E-A-T, which stands for Expertise, Authority and Trustworthiness. These are few of the things Google consider in terms of ranking. Google also recently added another 'E' to the concept. Which stands for 'Experience', means Google now consider someone with first-hands experience more authoriative. Thus, newer websites are harder to rank now than ever before. That's why it's more important now for newer sites to focus on their niche and cover all the related contents before branching out to other topics.
