We have found following title:

"Trang chủ - Bảo vệ môi trường"

Length: 29 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. (

Description Metatag

We have found following description:

"Trang chủ - Bảo vệ môi trường"

Length: 29 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

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

The Text to HTML ratio is 9.60%
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%

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.
