Technical SEO is the practice of optimizing a website for search engines with the goal of improving the visibility of the site and earning higher search engine rankings. One important aspect of technical SEO is website architecture, which refers to how well the website is structured and coded. A well-structured website is easy for search engine crawlers to read and index, making it more likely to earn a high ranking. Another important aspect of technical SEO is site speed, which refers to how quickly the website loads. Search engines prefer websites that load quickly, so optimizing site speed can improve visibility and rankings. Technical SEO also includes other factors such as mobile friendliness, crawlability, and security. By focusing on these technical aspects of SEO, businesses can improve their visibility and earn higher search engine rankings.
