At Marketing Ninjaz, we like to compare Search Engine Optimization to a three-legged stool. Without all three legs, the stool is unstable and will fall over. We define the three legs, or pillars, of SEO as the following:

• Technical Optimization: Website improvements that positively impact SEO that are not related to your website's content. This includes things like website hosting speed, optimizing images and other assets for faster loading times, and ensuring the your website has an SSL certificate.
• 
  
• On-Page Optimization: Efforts to ensure the content on your website is relevant in search and provides value to the user. This includes targeting the right keywords, ensuring complete and accurate meta information, and making sure that media is optimized with "alt text" and appropriate file names.
• 
  
• Off-Page Optimization: Efforts to elevate your websites search ranking results through efforts that occur outside of your website. These include creating, claiming, and maintaining business listings; establishing an active social media feed, and getting your website cited in articles and other media. This also includes reputation management in the form of reviews and review responses.

Ultimately, the goal of these strategies is to provide search engines with trustworthy, quality data. The more quality data that relates to the questions and queries users are asking, the better your website will rank.
