Traffic Rank

Traffic Rank is provided by Alexa

Visitors Localization

visitors
No data available.
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. (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: 162
Missing alt tag: 4

List of images with missing ALT attributes:

  • data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAABEwAAAK8AQMAAADPjbjaAAAAA1BMVE...g==
  • https://nxcompressor.com/wp-content/uploads/2023/11/3-3.webp

  • https://nxcompressor.com/wp-content/uploads/2023/02/nx-logo.png
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:

"Industrial Air Compressor Manufacturer since 1985 - Nanxiang"

Length: 60 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:

"Nanxiang is a leading industrial air compressor manufacturer offering high-quality screw air compressors and oil-free air compressors since 1985."

Length: 145 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.

Keywords Metatag

SEO-content
No Keywords Found.
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.

Text to HTML Ratio

SEO-content
The Text to HTML ratio is 0.85%
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 6% 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 6% can indicate that the word or a phrase appears too many time in the content.

Frames

accessibilitySEO-content
No frames detected. We found 1 inline frame(s).
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
Yes, custom 404 error page detected.
A 404 is a standard http response code for a resource that cannot be located on the server. Web servers 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)

SEO-Authority
Your domain expires in: 9 months, 22 days, 5 hours.

Good, your IP 194.1.147.20 is not blacklisted.
Spammer directories provide lists of IPs from which spam distribution is reported. Emails sent from the blocked IPs are subject to closer scrutiny and are much less likely to be delivered.

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. (https://technet.microsoft.com/en-us/library/cc731109)

Whois Privacy

security
