The complex and evolving technology infrastructure of Web 2.0 includes server-software, content-syndication, messaging-protocols, standards-based browsers with plugins and extensions, and various client-applications.

A Web 2.0 website may typically feature a number of the following techniques:

* Ajax-based rich Internet application techniques
* Non-Ajax-based rich Internet application techniques
* CSS
* Syndication and aggregation of data in RSS/Atom
* Clean and meaningful URLs

* Use of wiki software either completely or partially (where partial use may grow to become the complete platform for the site)
* Weblog publishing
* Mashups
* REST or XML Webservice APIs
