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:

"Teslaman High Voltage Power Supply"

Length: 34 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:

"As a professional supplier of high-voltage power supply market, TESLAMAN is committed to provide high-efficient, reliable digital and intelligent high-voltage power supply for users in medical, semiconductor, energy, X-ray and scientific research fields."

Length: 254 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
We have found 5 keywords:
  • high voltage power supply
  • HV power supplies
  • x-ray power supply
  • HVP Power Supply
  • HV generator
Length: 92 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.

Text to HTML Ratio

SEO-content
The Text to HTML ratio is 27.76%
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.
