To make sure that your website is designed in a way that search engines will be able to crawl and index it easily, you’ll need to focus on page speed, creating internal links, and optimizing it for mobile. Also, when you create internal links, make sure that all the links actually work. Other ways that you can improve technical SEO is to make sure your website is secure and that you’ve used only unique content (so remove any content that’s too similar to content published elsewhere).
