To work on technical SEO, you can follow these steps:
Website structure: Make sure your website has a logical and easy-to-follow structure, with clear navigation and well-organized content. Use headings, subheadings, and other formatting elements to structure your content and make it more user-friendly.
URL structure: Optimize your URL structure by making it concise, descriptive, and including target keywords where appropriate. Avoid using dynamic or parameter-based URLs, and make sure your URLs are static and easily understandable.
Site speed: Optimize your website's speed by reducing file sizes, compressing images, and minifying CSS and JavaScript files. You can also use tools such as Google Pagespeed Insights to identify specific speed issues and make recommendations for improvement.
Mobile optimization: Make sure your website is optimized for mobile devices by using responsive design, making sure your content is easily readable on smaller screens, and using mobile-friendly technologies such as HTML5 and CSS3.
Indexing and crawlability: Improve search engine crawlability by using sitemaps and robots.txt files to indicate which pages should and should not be crawled by search engines. You can also use meta tags, such as "noindex" and "nofollow", to control the way your pages are crawled and indexed.
Schema markup: Use schema markup to provide structured data to search engines about the content and organization of your website. This can improve visibility and ranking in rich snippets and other search features.
Security: Implement security measures, such as SSL certificates, to protect your website and its visitors from cyber threats.
Remember, technical SEO is just one aspect of a comprehensive SEO strategy, and should be combined with on-page optimization and other efforts to achieve the best results.
