As part of a website relaunch, an SEO relaunch is often set up. With an SEO relaunch, it is ensured that the existing search engine ranking of the existing website is not lost when switching to the new website. The aim of the SEO relaunch is also to place the new site even better in the SERPs with suitable content. A website relaunch is confusing for the Googlebot in the first place. You change the content, links and maybe even the website URL. So that Google can still read your new content and assign it correctly, it is important that you create redirects. Don't just redirect from the subpages of your old homepage to the new homepage of the website. Forward your old pages in a structured way to the new pages that match your old content. This makes it easier for Google to crawl your new page. Also, before the relaunch, evaluate which keywords and which links your existing page ranked well for and use these on your new page as well. If you do not follow these steps, Google may not recognize your new website and not classify it as "trustworthy". As a result, your site will lose in the ranking and will be difficult to find by your (potential) customers.
