Unlike traditional websites, which require the HTML and other page content to be loaded each time the user views a new page, SPAs load the page only once. SPAs dynamically update the page based on user interactions, rather than loading new page content for each user action. This shortens the time it takes for the user to interact with the application. You can think of SPAs as a large workout room where all the equipment is at the same time and you can move from one piece of exercise equipment to
Regular websites, on the other hand, have a more strict separation and subdivision of their content depending on the pages. All training equipment of sport A is in room A (page A), all equipment of sport B is in room B (page B) and so on.
In addition, as a developer of SPAs, it is sometimes necessary to create artificial URLs and artificial pages (rooms) within the Single Page Application so that Google can perceive and index the content (in the above example, training equipment) separately from one another. If all content is accessible under a single URL or page, this makes it more difficult for Google to index the content, which can have a negative impact on search engine optimization.
In addition, SEOs and developers should ensure that all pages within the website architecture are linked and accessible with their defined URLs. Furthermore, it must be ensured that each individual page uses appropriate meta tags. On the one hand to be able to control the indexing of the page. On the other hand, to give it more context by maintaining the title and meta description and to be able to control the presentation in the search results.
