Top priorities for website improvement

Images2.4
45% of images have a clearly defined size
No images are being resized by the browser
- Most images (55.0%) 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.
- 62 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

Internal links8.0
- 30 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.
Server behaviour8.2
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 follows the best practice of using a permanent (HTTP 301) redirect between URLs with/without trailing slashes. This is ideal.
- There is duplicate content on http://www.sdat.co.jp and http://sdat.co.jp. 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.
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.
