SEO of the tourist site. Traffic increased by 5 times

This case is dedicated to the tourist site. It is focused on a special region. With good competition, with old sites that have a large number of pages.
The customer came with the site on WordPress, with additional modules that were focused on the functionality of touring and orders. It is important to note that at the time of work, the site had no Semantic core or elaborate structure based on statistics from search engines. This was the initial task to fix.
