Look through the key statistics analysis before diving in deeper into our report:
Parameter | Current result | Assessment |
---|---|---|
Meta title | 51Book-大交通 商旅 旅游 | As meta title is a ranking factor, it's quite important to stick to search engine recommended length of aroun 50-60 characters. This website's meta title is 16 characters long. |
Description | 51Book创立于2007年,是中国领先的大交通及旅游产品预订网站。向超过20万企业客户提供国内机票、国际机票、邮轮、高铁等大交通和旅游产品解决方案,年交易额近250亿元。 | This meta description is 86 characters in length. Google suggests up to 320 characters at the very most to make sure the whole meta description is visible in search results page. |
<meta> keywords | 机票预订,国内机票,国际机票,邮轮,高铁,火车票,定制旅游,商旅,会奖机票,会展机票,境外电子客票,团队票 | Strangely enough, meta keywords still seem to be used. We would not go down that road unless very carefully - meta keywords have not been known as a positive ranking factor for a while now. |
Site speed | Around 1.4766 seconds | The website load speed is rather good. |
Alexa global rank | 409288, as last checked | Based on Alexa Global, we can assume the website is not very popular. Mind you, Alexa's worth is questionable at best. |
Links on homepage | Around 23 links | This is a well-judged amount of links for a homepage. |
HTML size | 14KB | A very good result, this. Remember, search engines such as Google place a lot of their website ratings on its speed. |
Website host server overview | Server status: online. Server IP address for this website is 115.182.240.37. | We apologize, but for some reason we were unable to gather enough data to provide a detailed insight at this time. |
If the basic information we presented you with above is not enough, get ready to dive in much deeper!
ALEXA rating is based on the number of visitors a given page receives. The higher the visitor count, the higher the rating. Currently, ALEXA has over 4 million websites indexed. If you sense cynicism in our words, you're not mistaken - we think Alexa rating is overrated, to put it mildly. A website's worth (and contextual popularity) is more than the sum of the views. So take the rank with a grain of salt.
Servers are physical storage devices that contain all the files and databases associated with a specific website, sometimes more than one. At times, a server makes up several virtual devices - separate servers used for shared hosting (tends to be cheaper). Entering website address into the address bar of your browser starts the request process during which your browser contacts the server and asks for specific files and database entries in order to display the requested website.
What follows is certainly very geeky, but informative for the knowing. Dig in:
