Make sure each page has a unique title and use your most important keywords. For internal pages start your title tags with your most important keyword(s).

Meta descriptions allow you to influence how your web pages are described and displayed in search results. A good description acts as a potential organic advertisement and encourages the viewer to click through to your site.
Keep it short and to the point; the ideal meta description should contain between 70 and 160 characters - spaces included (600 - 940 pixels).
Ensure that each of your web pages have a unique, straightforward meta description that contains most important keywords. These keywords are especially important because they appear in bold when they match the user’s search query (See the Google Preview below).

We found 1 web feed URL(s) on this web page.
Warning, no 301 redirects are in place to redirect traffic to your preferred domain. Pages that load successfully both with and without www. are treated as duplicate content!
Not all versions of your page point to the same URL.
Search engines see www.publications.rwth-aachen.de and publications.rwth-aachen.de as two different websites with the same content. This causes them to see a lot of duplicate content, which they don't like.
Use the rel="canonical" tag to tell search engines which is the definitive version of your domain. Use a 301 redirect to divert traffic from your secondary domain.
This issue can be caused by problems with a website's SSL configuration. Check your site's SSL configuration for any errors.

Your site currently has a robots.txt file. You can use Google Search Console's Robots.txt Tester to submit and test your robots.txt file and to make sure Googlebot isn't crawling any restricted files.
See the pages you've disallowed with your robots.txt file with Site Crawl.
XML sitemaps contain the list of your URLs that are available to index and allow the search engines to read your pages more intelligently. They can also include information like your site’s latest updates, frequency of changes and the importance of URLs.
Be sure to only include the pages you want search engines to crawl, so leave out any that have been blocked in a robots.txt file. Avoid using any URLs that cause redirects or error codes and be sure to be consistent in using your preferred URLs (with or without www.), correct protocols (http vs. https) and trailing slashes. You should also use your robots.txt file to point search engine crawlers to the location of your sitemap.

Warning! We've detected parameters in a significant number of URLs.
No hreflang tags were found on this page
We found underscores in this URL and/or in your in-page URLs.
Using underscores in your URL makes it hard for search engines to determine your site's relevance to a search. Google sees hyphens as word separators while underscores are ignored. So the search engine sees https://publications.rwth-aachen.de/search_generator.py as all one word. Use hyphens in your URLs instead: https://publications.rwth-aachen.de/search-generator.py.
We've detected underscores in your URLs. Change underscores to hyphens to maximize your SEO.
