Crawlability refers to the ability of search engines to navigate and index a website's pages. Technical SEO specialists ensure that all of a website's pages are accessible to search engines, with no broken links or pages that are blocked by robots.txt files. They also use tools such as XML sitemaps to help search engines understand the structure of the site and prioritize the most important pages for indexing. Site architecture is another important aspect of technical SEO. A well-designed site architecture can improve user experience and make it easier for search engines to crawl and index a website. Technical SEO specialists ensure that a website's structure is logical and hierarchical, with clear categories and subcategories, and that internal linking is used to connect related pages. Finally, structured data is a type of markup that helps search engines understand the content of a website's pages. Technical SEO specialists use structured data markup to provide additional information about a website's content, such as product information, reviews, and event details. This information can appear in search results as rich snippets, which can improve click-through rates and drive more traffic to a website. Overall, technical SEO is an essential aspect of search engine optimization that can have a significant impact on a website's visibility and ranking. By optimizing a website's technical infrastructure, businesses can improve user experience, increase engagement, and attract more organic traffic to their site.
