- Current cruise industry updates
- Copyright © 2000-2026

DOM element which contributes the most to CLS score:
Html: <div class="item w25">
Score: 0.0496
This test will check the Cumulative Layout Shift (CLS) score of the analyzed webpage. CLS is a Core Web Vitals metric calculated by summing all layout shifts that aren't caused by user interaction. Basically, whenever a page loads, certain page elements unexpectedly shift, affecting the way users interact with the webpage. A website with a low CLS has a stable page display, which does not shift elements around and ensures a steady, predictable loading of all website content. To provide a good user experience, Google recommends that sites should strive to have a CLS score of 0.1 or less.

https://www.seereisenportal.de/ and https://seereisenportal.de/ resolve to the same URL.
Test your site for potential URL canonicalization issues. Canonicalization describes how a site can use slightly different URLs for the same page (e.g., if http://www.example.com and http://example.com displays the same page but do not resolve to the same URL). If this happens, search engines may be unsure about which URL is the correct one to index. Learn more about canonicalization issues.

Check if your website is using HTTPS, a secure protocol for sending/receiving data over the Internet. Using HTTPS indicates that an additional encryption/authentication layer was added between client and server. HTTPS should be used by any site that collects sensitive customer data such as credit card information. Even for sites that do not collect such data, switching to https helps users by improving privacy and overall security. Google is increasingly using https as a positive ranking factor.
Mixed Content Test (HTTP over HTTPS)
100% of top 100 sites passed
This value indicates the percent of top 100 most visited websites in the US that pass this test (in the past 12 months). Failing a test that a high percentage of top websites are passing may indicate an industry best practice that you should be fixing.
This webpage does not use mixed content - both the initial HTML and all other resources are loaded over HTTPS.
This will check if all resources are loaded over a secure HTTPS connection. Mixed content occurs when initial HTML is loaded over a secure HTTPS connection, but other resources (such as images, videos, stylesheets, scripts) are loaded over an insecure HTTP connection. This is called mixed content because both HTTP and HTTPS content are being loaded to display the same page, and the initial request was secure over HTTPS. Browsers may block mixed content, so fixing this issue helps ensure your content loads as intended.
HTTP2 Test

Plaintext Emails Test

This webpage does not include email addresses in plaintext.
Check your webpage for plaintext email addresses. Any e-mail address posted in public is likely to be automatically collected by computer software used by bulk emailers (a process known as e-mail address harvesting). A spam harvester can read through the pages in your site and extract plaintext email addresses which are then added to bulk marketing databases (resulting in more inbox spam). There are several methods for email obfuscation.
Unsafe Cross-Origin Links Test

This webpage is using target="_blank" links without rel="noopener" or rel="noreferrer" attribute, which can expose it to performance and security issues!
This test will check if all links to external pages that have the target="_blank" attribute also have the rel="noopener" or rel="noreferrer" attribute.
When you link to an external site using the target="_blank" attribute, security and performance issues arise:
The external pages you link to may run on the same process as your page. If the other page is running a lot of JavaScript, your page's performance may suffer.
The other page can access your window object with the window.opener property. This may allow the other page to redirect your page to a malicious URL.
Adding rel="noopener" or rel="noreferrer" to your target="_blank" links avoids these issues.
