Server behaviour6.9
404 page
Compression
- This website handles missing pages correctly by sending a 404 HTTP status code.
- This website was not served using 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.
- 2 of the pages of this website follow the best practice of using a permanent (HTTP 301) redirect between URLs with/without trailing slashes. These pages are ideal.
- Adding or removing a trailing slash to one 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.
- This test is not applicable as this website appears to be on a subdomain.
URL format7.2
2 URLs are less than ideal
- One URL is particularly hard to type or remember.
- Consider URL rewriting as an effective and transparent means of creating appropriate URLs. URLs using unusual characters (such as semi-colons or underscores), long numerals or complex phrasing are very difficult for real people to use or exchange. They also tend to be less favoured by search engines. Wherever possible ensure web addresses are 'human readable' - i.e. they should be easy to read, remember and type. In particular, avoid the use of obscure characters (including the underscore, which is not widely understood by non-technical users, or particularly memorable) and long numerals, e.g. example.com/23857984325.
- 2 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.
Images8.8
62% of images have a clearly defined size
8 images are being resized by the browser
- Some images (38.0%) 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.
Non Explicitly Sized Images
- 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.
- 8 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.
Page titles9.0
100% of pages have defined titles
20% of page titles are weak
- All pages were found to specify page titles, but one page has a relatively weak title which could be improved. Page titles appear in search results and at the top of the browser's window when visiting the site. Appropriate page titles are particularly important for search engine optimisation.
- Make sure that all pages have a descriptive title. Do not include the address of the page in the title, try not to use excessive punctuation and avoid common words like 'page'.
Page titles
| Page title | Notes |
| California Science & Engineering Fair | OK |
| Brief History of the California State Science Fair | OK |
| 404 Not Found | OK |
| 2024 California Science & Engineering Fair | OK |
| California Science & Engineering Fair - Judges Page | It is unnecessary to end the page title with "page" |
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.
