Technical SEO refers to the practice of optimizing the technical aspects of your website to improve its visibility and ranking in search results. This includes optimizing things like your website's structure, code, and content to make it more easily discoverable and understandable by search engines.

Technical SEO is different from other types of SEO, such as content SEO and link building, which focus on creating and promoting high-quality content and building links from other websites.

A clean and simple website structure helps search engines understand the hierarchy and relationships between different pages on your site.

4. Use alt text for images

Alt text is a text description of an image that is displayed when the image cannot be shown. It helps search engines understand the content of your images and can improve your search engine rankings.

9. Use structured data

Structured data is a standardized format for providing information about a webpage and its content. By using structured data, you can help search engines understand the content of your pages and provide rich snippets in search results.

HTTP/2 is a newer version of the HTTP protocol that is faster and more efficient than HTTP/1.1. By using HTTP/2, you can improve the speed and performance of your website and potentially improve your search engine rankings.

11. Use lazy loading

Lazy loading is a technique that delays the loading of images or other content until it is needed. This can improve the speed and performance of your website, especially on mobile devices with slower connections.

A CDN is a network of servers located around the world that delivers web content to users based on their geographic location. By using a CDN, you can improve the speed and performance of your website, especially for users located far from your server.

13. Use Gzip compression

Gzip compression is a technique that reduces the size of your website's files, making them faster to download and improve the speed and performance of your website.

14. Use browser caching

Browser caching is a technique that allows your website's files to be stored in a user's browser, so they don't have to be downloaded again when the user visits your site. This can improve the speed and performance of your website, especially for returning visitors.

15. Optimize your server infrastructure

Properly configuring your server infrastructure can improve the speed and performance of your website. This includes things like choosing the right hosting provider, using a fast and reliable server, and optimizing your database.

16. Use a caching plugin

A caching plugin is a tool that stores a copy of your website's pages in the cache, so they can be served to users more quickly. This can improve the speed and performance of your website, especially for returning visitors.

17. Optimize your images

Large images can slow down your website, so it's important to optimize them for the web. This includes compressing images, using the correct file format (e.g., JPG, PNG, GIF), and using appropriate image sizes.
