HIGH
To address URL canonicalization issues, it is recommended to select a primary URL for your webpage and set up redirects from all other variations to the preferred one.
HIGH
To improve the website experience for your visitors, it is recommended to eliminate any render-blocking resources on this webpage.
HIGH
Using images in a modern format can significantly reduce the file size and improve the loading speed of a webpage, providing a better user experience and potentially increasing engagement.
HIGH
By creating a custom 404 error page with helpful links and information, users are more likely to stay on the site and continue to explore.
MEDIUM
Serve properly sized images to reduce page loading times and to improve user's experience.
MEDIUM
Consider adding cache headers for images to improve website performance. With cache headers, browsers can cache images and serve them quickly to returning visitors, rather than re-fetching them each time.
MEDIUM
Avoid using distorted images, as they can have a negative impact on the user experience.
MEDIUM
Consider adding cache headers for CSS resources to speed up the webpage for returning users.
LOW
Use only one canonical link tag per webpage, as multiple tags will cause search engines to ignore all of them, potentially leading to duplicate content issues.

To protect against spam harvesters, consider hiding or obfuscating email addresses in your page code.
LOW
Using more than 20 HTTP requests on a webpage can negatively impact the loading time.
LOW
Strip out any unnecessary metadata to improve loading time, security, and privacy. Metadata should not exceed 16% of the image size.

Most Common Keywords Test
  • There is likely no optimal keyword density (search engine algorithms have evolved beyond keyword density metrics as a significant ranking factor). It can be useful, however, to note which keywords appear most often on your page and if they reflect the intended topic of your page. More importantly, the keywords on your page should appear within natural sounding and grammatically correct copy.
