Most Common Keywords Test
  • There is likely no optimal keyword density (search engine algorithms have evolved beyond keyword density metrics as a significant ranking factor). It can be useful, however, to note which keywords appear most often on your page and if they reflect the intended topic of your page. More importantly, the keywords on your page should appear within natural sounding and grammatically correct copy.

The canonical tag can be useful when there are similar versions of the same content on several URLs (e.g., such as e-commerce sites where URL modifiers like sort parameters are appended to a product page's URL). Please ensure that this specification is correct, as canonical tags are often hard-coded and may not always reflect the latest changes in a site's URL structure.
<link href="https://viettelnet.vn/author/sysadmin/" rel="canonical"/>
