1. What is technical SEO? Importance of preparing infrastructure
Technical SEO refers to optimizing the technical foundation of a website so that search engine crawlers (traveling programs) can efficiently collect information on the site and correctly register (index) it in the database.
While content SEO focuses on the ``content'' of ``what to convey'', technical SEO is the work of creating a ``pathway to convey the message correctly.''

Use canonical tags to clearly identify canonical URLs and organize your internal link structure into a pyramid to guide crawlers to prioritize the most important product categories.
4. Visualization of improvement effects and data analysis
After implementing technical SEO measures, check the indexing status using Google Search Console, etc. The graph below shows the change in the number of indexed pages after implementing crawlability improvement measures.
Setting appropriate structured data and increasing display speed (improving Core Web Vitals) are also important technical elements that support crawlability.
