What is Search Engine Optimization?

Search Engine Optimization, commonly known as SEO, is the process of improving the quality and quantity of traffic to a website from search engines.¹ The goal of SEO is to increase a website’s visibility and ranking in “organic” or unpaid search results, ultimately driving more relevant visitors to the site.²

How SEO Works

Search engines like Google, Bing, and Yahoo! use automated programs called crawlers or spiders to navigate the web and discover new and updated content.³ This process has three main steps:⁴

1. Crawling: The crawlers follow links from page to page, gathering information about each page.⁵

    

2. Indexing: The search engine analyzes and stores the crawled content in a massive database, known as the index.⁶

    

3. Ranking: When a user enters a search query, the search engine’s algorithm evaluates its index to find the most relevant and authoritative pages to display in the search results.⁷ The order in which these pages appear is their ranking.⁸

    

Key Components of SEO

SEO is a multifaceted practice that involves various techniques.⁹ These are often categorized into three main areas:¹⁰

• On-Page SEO: This involves optimizing elements on your website to make it more appealing to both search engines and users.¹¹ This includes:

   

  • Keyword Research: Identifying the words and phrases your target audience uses to search for information.
  • Content Quality: Creating high-quality, relevant, and comprehensive content that answers user queries.
  • HTML Tags: Optimizing elements like title tags, meta descriptions, and headers with relevant keywords.¹²

     

  • Internal Linking: Creating links between pages on your own website to help crawlers and users navigate the site.¹³

     

• Off-Page SEO: This focuses on activities done outside of your website to improve its authority and credibility.¹⁴ The most significant factor in off-page SEO is link building, which involves getting other reputable websites to link to your content.¹⁵ A link from a trusted source acts as a “vote of confidence” for your website, signaling to search engines that your content is valuable.¹⁶

   

• Technical SEO: This ensures that search engine crawlers can efficiently access, crawl, and index your website.¹⁷ It often happens “behind the scenes” and includes things like:

   

  • Site Architecture: Organizing your website in a logical and easy-to-navigate manner.¹⁸

     

  • Page Speed: Ensuring your pages load quickly to provide a good user experience.¹⁹

     

  • Mobile-Friendliness: Making sure your website is optimized for mobile devices, as a majority of searches are now performed on phones.²⁰

     

  • XML Sitemaps: Submitting a sitemap to search engines to help them discover all the pages on your site.²¹

     

  • HTTPS: Using a secure connection (HTTPS) for your website.²²
