Mobile3.0
- None of this website appears to be fully optimised for viewing on a mobile or tablet (using CSS media queries). It is important to make sure your content can be viewed easily across a wide range of devices as a growing percentage of web browsing is now done on phones and tablets.
- Check how the website looks using a mobile and a tablet. Consider adding mobile-only styling using media queries. Some websites employ other techniques for mobile visitors which we cannot currently detect.

URL format4.4
4 URLs are less than ideal
- 2 URLs are 'dirty'. 'Dirty' URLs include one or more parameters after a question mark (e.g. www.example.com/?pagename=news), instead of a clean URL (e.g. www.example.com/news). Dirty URLs should generally be avoided wherever possible - they are almost impossible for human beings to remember, may expose the technology of the website to hackers and can confuse search engines among other problems. Their use is sometimes necessary for specific applications, and acceptable in small amounts.
- Remove or reduce the number of query parameters in URLs. Consider URL rewriting as an effective and transparent means of creating appropriate URLs.
- 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.

Server behaviour5.2
404 page
Compression
- This website handles missing pages correctly by sending a 404 HTTP status code.
- 4 pages of this website were not served with GZIP encoding. GZIP compression is widely supported and reduces the load time of a web page.
- Enable GZIP compression on your web server or in your application for all pages.
- One page of this website returns page content with or without a trailing slash on its URL. Search engines might see these as separate pages with duplicate content which they could penalise for.
- Use a 301 redirect or a canonical meta tag to force search engines to see the correct version.
- Adding or removing a trailing slash to 2 of the URLs of this site returns an error page (404). This is OK as no content is being duplicated, but visitors might try browsing to the pages of this website with or without a trailing slash. Ideally, the alternate URL should redirect to the correct page.
- Add a 301 redirect from the other version to the canonical URL.
Unhandled alternate URLs
- Add a 301 redirect from the other version to the canonical URL.
- There is duplicate content on http://www.rebol.com and http://rebol.com. This is bad, as technically they are classed as two different websites. Search engines may lower a website's rank if they find the same content on two different URLs.
- Choose one domain that you would like to use and then set a permanent (HTTP 301) redirect to forward users who visit the other.

Images8.3
83% of images have a clearly defined size
5 images are being resized by the browser
- Some images (17.0%) don't 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.
- Add width and height attributes to all image tags. The width and height you specify should be the same as the source image. If you want to resize an image in the browser, use CSS.
- 5 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.
Headings9.0
- All pages were found to use defined headings. This is excellent as it allows visitors and search engines to summarise the content of webpages quickly. Correctly defined headings aid accessibility and are particularly important for search engine optimisation.
- Some pages did not define headings correctly. The H1 tag should be used for the most top-level heading, with H2 being used for sub-headings and H3 for further sub-headings and so-on. Not conforming to this convention may confuse visitors.
- Ensure that headings are defined in a semantically correct way, i.e. always start with a H1 tag. This is used to summarise the page content. Further tags (H2, H3, H4 etc) are meant to summarise and partition sections within the content.
