Technical SEO refers to the process of optimizing a website's infrastructure to help search engines crawl and index it more efficiently. Unlike content-based SEO, which focuses on keywords and on-page optimization, technical SEO deals with backend elements that affect site performance, accessibility, and search engine visibility.

Key aspects of technical SEO include:

Site Speed: Faster-loading websites improve user experience and are favored by search engines. Optimizing images, leveraging browser caching, and using Content Delivery Networks (CDNs) are common practices to enhance speed.

Mobile Optimization: With the increasing use of mobile devices, it’s crucial to ensure that a website is mobile-friendly. Responsive design helps make websites accessible across various screen sizes and improves rankings.

Crawlability and Indexability: Search engines need to crawl and index a website effectively. Technical SEO involves creating clean, efficient site structures, fixing broken links, and generating XML sitemaps to guide search engines.

Security: Secure websites (with HTTPS) are preferred by search engines as they offer a safer browsing experience.

Structured Data: Implementing schema markup helps search engines understand the content better and can improve rich results.
