Issues to fix
HIGH
https://isro.eu/sitemap_de.xml and https://www.isro.eu/sitemap_de.xml should resolve to the same URL, but currently do not.
HIGH
This webpage does not contain H1 headings! H1 headings help indicate the important topics of your page to search engines. While less important than good meta-titles and descriptions, H1 headings may still help define the topic of your page to search engines.
HIGH
The most common keywords of this webpage are not distributed across the important HTML tags! Primary keywords should appear in title tag, meta description and heading tags to help Search Engines to properly identify the topic of this webpage.
HIGH
This webpage is not using a meta description tag! You should include this tag in order to provide a brief description of your page which can be used by search engines. Well-written and inviting meta descriptions may also help click-through rates to your site in search engine results.
HIGH
This webpage is not using a title tag! A missing or poor title tag (that does not target important keywords or phrases) will make it difficult for your page to rank well in search engines.
HIGH
This website is not using a custom 404 error page! Default 404 error pages result in a poor experience - it can mislead users into thinking an entire site is down or broken, greatly increases the chance they leave the website entirely, and looks unprofessional. We recommend to have a custom 404 error page in order to improve the website's user experience by letting users know that only a specific page is missing/broken (and not the entire site), providing them helpful links, the opportunity to report bugs, and potentially track the source of broken links.
HIGH
This webpage doesn't take the advantages of HTML Microdata or JSON-LD specifications in order to use structured data! View Google's guide for getting started with structured data.
HIGH
This webpage is not using CSS media queries. We recommend the use of this technique in order to implement responsive design functionalities.
HIGH
This webpage does not have a viewport meta tag! Add a viewport meta tag to optimize your webpage for mobile screens.
HIGH
This webpage is not connected with social media using the API's provided by Facebook, Google +, Twitter, Pinterest, or using addthis.com
MEDIUM
The Document Object Model (DOM) of this webpage has 3,757 nodes which is greater than the recommended value of 1,500 nodes! A large DOM size negatively affects site performance and increases the page load time.
MEDIUM
A Google Analytics script is not detected on this page. While there are several tools available to monitor your site's visitors and traffic sources, Google Analytics is a free, commonly recommended program to help diagnose potential SEO issues.
MEDIUM
This webpage is not using social media meta tags! While this type of meta tags don't affect what people see when they visit the webpage, they exist to provide information about it to search engines and social media platforms.
LOW
This webpage doesn't have a character encoding declaration! If the server doesn't specify which character encoding format it's using when it sends an HTML file, the browser may display some characters incorrectly. A character encoding declaration is required (either in the Content-Type header or explicitly in the file using a meta tag) even when all characters are in the ASCII range, because a character encoding is needed to process non-ASCII characters entered by the user in forms, in URLs generated by scripts, and so forth.
LOW
This webpage is not using the Strict-Transport-Security header! This is a security header that was created as a way to force the browser to use secure connections when a site is running over HTTPS.
