51ditu.com is a Chinese website that provides electronic maps, bus routes, and driving navigation in various cities across China. Its homepage is titled "我要地图首页", and its description states that it offers map searches, queries, and other related services. Visitors can search for maps of different Chinese cities, such as Beijing, Shanghai, Shenzhen, Hangzhou, Guangzhou, Wuhan, Chengdu, Jinan, Nanjing, among others.

With over 26,512 unique visitors per day and 132,560 page views, the website is quite popular and valuable, with an estimated worth of $198,600 USD. It is hosted by CN hosting firm Hangzhou Alibaba Advertising Co., Ltd. The website's top-level domain is .COM, which indicates that it is a commercial site.

Its primary target audience is individuals who need to search for directions, especially those who reside in China or are visitors to the country. Given that it offers mapping services, driving navigation, and public transportation search capabilities, the 51ditu site is practical, informative, and oriented towards serving its user base.

Regarding whether the site is family-friendly, it is difficult to ascertain with the limited information available. While the site generally provides mapping and transportation information, it is essential to note that it may contain ads and external links that may not be appropriate for younger audiences.

Finally, it is worth noting that the website's page speed insights score quite low, with a score of 52/100 for desktop and 43/100 for mobile devices. This score is lower than expected from a well-established website, and consequently, site owners may have to review their optimization and technical functionalities carefully. Nevertheless, the website is secure, as evidenced by its HTTPS protocol.

Warnings

The character encoding “gb2312” is not widely supported. Better interoperability may be achieved by using “UTF-8”.

Using “gbk” instead of the declared encoding “gb2312”.

The “type” attribute is unnecessary for JavaScript resources.

The “language” attribute on the “script” element is obsolete. You can safely omit it.

Consider adding a “lang” attribute to the “html” start tag to declare the language of this document.

Errors

Legacy encoding “gbk” used. Documents must use UTF-8.

Bad value “text/html; charset=gb2312” for attribute “content” on element “meta”: “charset=” must be followed by “utf-8”.

Bad value “Content-Script-Type” for attribute “http-equiv” on element “meta”.

A “meta” element with an “http-equiv” attribute whose value is “X-UA-Compatible” must have a “content” attribute with the value “IE=edge”.

An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.

End tag for “body” seen, but there were unclosed elements.

Unclosed element “div”.
