Headings0.0
- A large number (60.0%) of pages do not use defined headings. This means that users and search engines may find it harder to determine the content of this website's pages. Correctly defined headings aid accessibility and are particularly important for search engine optimisation.
- Define meaningful headings for all webpages. This is likely to help this website's search engine placement and assist visitors in navigating content.
- 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.

Server behaviour8.0
404 page
Compression
- This website handles missing pages correctly by sending a 404 HTTP status code.
- This website was served with GZIP encoding. This is very good because it reduces the loading time of a web page.
- This website returns page content with or without a trailing slash on the URLs. 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.
Duplicate pages
- Use a 301 redirect or a canonical meta tag to force search engines to see the correct version.
- This test is not applicable as this website appears to be on a subdomain.
Amount of content8.6
Rendering Chart...
- This website has an average of 457 words per page. The amount of content on a website has been shown to correlate with its search engine ranking.
- Consider the amount of text on this website and increase it if appropriate.
Amount of content discovered
| Page | Characters | Words |
| studio.code.org/users/sign_in | 3688 | 561 |
| studio.code.org/projects/public | 2873 | 426 |
| studio.code.org/incubator | 2875 | 426 |
| studio.code.org/catalog | 2875 | 426 |
| studio.code.org/users/.../new | 3021 | 446 |
URL format8.8
1 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.
Images9.8
11% of images have a clearly defined size
4 images are being resized by the browser
- Most images (89.0%) 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.
- 4 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.
