URL format5.2
4 URLs are less than ideal
- 4 URLs include a file extension.
- Avoid use of file extensions wherever possible. File extensions appear at the end of web addresses, and have several negative effects. They make the address harder to remember or type (particularly for non-technical users), and can reveal the underlying technology of the website making it very slightly more vulnerable to hackers. They also tie the implementation of the website to a specific technology, which can make subsequent migration of URLs difficult. Consider URL rewriting as an effective and transparent means of creating appropriate URLs.
Images8.0
100% of images have a clearly defined size
24 images are being resized by the browser
- All images have defined sizes using width and height attributes in the HTML. These attributes are optional, but strongly recommended as they help the browser arrange the page more quickly.
- 24 images are being stretched in the browser.
- The width and height you specify in an image tag should be the same as the source image. If you want to resize an image in the browser, use the CSS width and height properties.
Stretched Images
- The width and height you specify in an image tag should be the same as the source image. If you want to resize an image in the browser, use the CSS width and height properties.
Internal links9.5
- 7 links use text that is too long. Links should describe what they link to briefly. Linking a long block of text usually indicates an attempt to trick search engines into ranking those keywords highly (a strategy which does not work). Long linked blocks of text are also harder for people to scan.
- Consider shortening long anchor text.
Overly long link text
