Registering country code top level domains (ccTLD) can prevent potential competitors from taking advantage of your primary domain reputation. It is also one of the ways to improve country specific SEO and performance. (http://www.searchenginejournal.com/seo-without-boarders-a-guide-to-international-seo-nick-paterman/60092/)

Images

accessibilitySEO-content
Good, most images have ALT attribute.
Number of images: 14
Missing alt tag: 1

List of images with missing ALT attributes:

  • http://www.pcnc.top/themes/clean/style/color/me.gif
The "alt" attribute provides a text equivalent for the image. If the browser cannot display an image the alt description will be given in its place. Furthermore, some visitors cannot see images as they might be blind in which the alt tag provides a valuable image description. Finally, search engines utilize the alt attribute for image search indexing. (www.w3.org/QA/Tips/altAttribute)

Title

SEO-content
We have found following title:

"数控车床_数控铣床_数控冲床_数控机床_数控编程_数控技术 - 华夏数控技术网"

Length: 39 characters
The <TITLE> element provides a short piece of text describing the document. The title is very important as it shows in the window title bars, bookmarks and search results. Title should be between 60 to 80 characters long. (www.w3.org/QA/Tips/good-titles)

Description Metatag

SEO-content
We have found following description:

"华夏数控技术网是一家学习数控工作原理、交流数控编程心得、讨论数控机械加工、研究数控技术应用的专业网站,是数控车床和数控铣床的手工编程与自动编程(CAD/CAM)、数控系统研究与开发、数控雕刻机、数控木工车床和数控钻床设计等技术交流平台,也是数控初学者和数控爱好者的乐园。"

Length: 135 characters
The description attribute should provide a concise explanation of a Web page's content. Also, the description is often displayed on search engine results and can indirectly affect page ranking. (en.wikipedia.org/wiki/Meta_element#The_description_attribute)

Keywords Metatag

SEO-content
We have found 1 keywords:
  • 数控车床,数控铣床,数控冲床,数控机床,数控编程,数控技术
Length: 29 characters
The keywords attribute was utilized by search engines to provide more accurate search results. Due to the over usage and spamming the keywords attribute has been phased out and is no longer relevant. Google doesn't use the "keywords" meta tag in web search ranking.(googlewebmastercentral.blogspot.se/2009/09/google-does-not-use-keywords-meta-tag.html)

Text to HTML Ratio

SEO-content
The Text to HTML ratio is 10.43%
Original content is by far the single most important element to search engines. Low Text to HTML ratio indicates little content for search engines to index. We consider it to be good practice to have a Text to HTML ratio of at least 10% and ideal above 20%

Warning: Keywords density of above 5% might have negative impact on search engine listing

Keywords density and consistency are notable factors for optimal page SEO. Preferred keywords should have higher keywords density indicating their importance. Optimally, preferred keywords should also be consistently utilized in multiple essential areas of the page such as title, description meta tag, h1 through h6 headings, alt image attributes, backlinks and internal links anchor text. Keyword density of above 5% is a good indication that the word or phrase appears too many time in the content. (more information)

Frames

accessibilitySEO-content
No frames detected.
It is not recommended to use frames or iframes because they can cause problems for search engines. It is best to avoid frames and inline frames whenever possible (searchenginewatch.com/article/2064573/Search-Engines-and-Frames). If frames must be utilized consider <noframes> tag. (www.w3schools.com/tags/tag_noframes.asp).

Custom 404 Error Page

usability
No custom 404 error page detected.
A 404 is a standard http response code for a resource that cannot be located on the server. Webservers usually return a "404 Not Found" error page for non-existing pages. Unfortunately, these default error pages are very generic and a not very user friendly, therefore, using a custom 404 error page is highly recommended.

Process of returning http status code "200 OK" for a non-existent page or redirecting users to another url is called soft 404. Soft 404 errors are problematic for search engines and are not advisable. (https://support.google.com/webmasters/answer/181708)

Domain Expiration

SEO-Authority
Data could not be obtained.
Domain expiration far in to the future is considered a good practice as it promotes confidence in your website, decreases chances of losing domain and in certain cases might help with search engine ranking. (http://www.hover.com/blog/three-reasons-to-renew-your-domain-names-for-five-years)

IP Canonicalization

SEO
No, your site's IP 58.64.189.118 does not redirect to pcnc.top.

URL Canonicalization

SEO
Yes, both the www.pcnc.top and pcnc.top resolve to the same URL.
Domain name with WWW and without can be considered as different pages causing duplicate content for search engines. (www.mattcutts.com/blog/seo-advice-url-canonicalization)

HK , Central District
Your server's IP address and location have minor impact on the country specific SEO. It is recommend to host the website in the country where the number of vistors is desired to be the highest. Search engines take the geolocation of a server into account. (http://www.youtube.com/watch?v=hXt23AXlJJU)

HTTPS (SSL)

security
No HTTPS (SSL) found.
Google™ is now treating HTTPS as a ranking signal. HTTPS is a secure web protocol that allows for encrypted communication between website and the client.

security
Great, your server has directory browsing disabled.
Protect Webserver directories from unwanted browsing. To enhance security, directory browsing should be disabled unless you have a specific reason to enable it. If you enable directory browsing, make sure that you only enable it on the particular directory or directories that you want to share. (http://technet.microsoft.com/en-us/library/cc731109)
