Top priorities for website improvement

- Remove or reduce the number of query parameters in URLs. Consider URL rewriting as an effective and transparent means of creating appropriate URLs. (read more)
- Consider shortening long anchor text. (read more)
Twitter0.0

- This website did not contain a link to Twitter.
- Sign up for a Twitter account and make sure it is linked to from your site.
URL format5.2
4 URLs are less than ideal
- 4 URLs are 'dirty'. 'Dirty' URLs include one or more parameters after a question mark (e.g. www.example.com/?pagename=news), instead of a clean URL (e.g. www.example.com/news). Dirty URLs should generally be avoided wherever possible - they are almost impossible for human beings to remember, may expose the technology of the website to hackers and can confuse search engines among other problems. Their use is sometimes necessary for specific applications, and acceptable in small amounts.
- Remove or reduce the number of query parameters in URLs. Consider URL rewriting as an effective and transparent means of creating appropriate URLs.
- 80.0% of URLs include an ID query parameter (e.g. www.example.com?sessionid=1234).
- Avoid use of any query parameter ending in id, e.g. 'sessionid;' Google explicitly states that it will not include pages with this format in their index. Consider URL rewriting as an effective and transparent means of creating appropriate URLs.
Internal links8.4
- 5 links use text that is too long. Links should describe what they link to briefly. Linking a long block of text usually indicates an attempt to trick search engines into ranking those keywords highly (a strategy which does not work). Long linked blocks of text are also harder for people to scan.
- Consider shortening long anchor text.
