Thuật ngữ SEO

Mọi thuật ngữ SEO quan trọng đều được giải thích.


10x Content

Content that is at least ten times better than the current top-ranking result for the target keyword.

301 Redirect

The 301 redirect takes users to the new URL and tells search engines that the page has moved permanently.

Alt Text

Adding alt text to images is, first and foremost, a matter of improving web accessibility. Millions of visually impaired users use screen readers when consuming online content - and for them, having the text equivalent to the visually displayed information is crucial.


Backlinks (same as inbound links) are links to a particular web page or resource from other web pages. Backlinks refer to the incoming links only. Links from a page are called outgoing links (but at the same time, they are backlinks for the linked pages).

Cached Page

Then there’s something called server caching. CDNs - or Content Delivery Networks - will cache web content (images, videos, and webpages) in so-called “proxy servers” located closer to the end user than the website servers.

Dofollow Link

A dofollow link is any link with no “nofollow,” “UGC,” or “sponsored” attribute. Dofollow links can be followed by search engine crawlers and transfer link equity to the linking site, which influences the page rankings.
