Top priorities for website improvement
- 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. (read more)

- Sign up for a Twitter account and make sure it is linked to from your site. (read more)

Images2.4
60% of images have a clearly defined size
19 images are being resized by the browser
- Some images (40.0%) 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.
- 46 images are not in a web-friendly format.
- Make sure all images on this website are JPEG, PNG, SVG or GIF format.
Non Web-Format Images
- Make sure all images on this website are JPEG, PNG, SVG or GIF format.
- 19 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.
- We were not able to test every image on this website as checking them was taking too long.
Internal links6.3
- 26 links have no text describing their destination. Links on a page should describe their destination for the benefit of both screen readers and search engine spiders.
- Add meaningful anchor text that describes the link's destination. If the link contains an image, ensure you have provided alt text.
Empty link text
- Add meaningful anchor text that describes the link's destination. If the link contains an image, ensure you have provided alt text.
Headings9.0
- All pages were found to use defined headings. This is excellent as it allows visitors and search engines to summarize the content of webpages quickly. Correctly defined headings aid accessibility and are particularly important for search engine optimization.
- 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.
