No Analytics Solution

Meta tags2.0
- All pages include at least some metadata, but no pages have a description meta tag. The description meta data is important as it appears on Google's search result pages.
- Make sure that all the pages of this website include a meta description. If you don't include one, Google will choose a sample of text from the page to appear in the search engine result. By including a meta description, you can control how your search engine result will appear.
Pages with no meta description
- Make sure that all the pages of this website include a meta description. If you don't include one, Google will choose a sample of text from the page to appear in the search engine result. By including a meta description, you can control how your search engine result will appear.
Meta Tags (name attribute)
URL format7.6
2 URLs are less than ideal
- 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.
Images8.3
86% of images have a clearly defined size
12 images are being resized by the browser
- Some images (14.0%) 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.
- 12 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.
Internal links8.5
- 7 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 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.
