Definition:
An Internet forum is an online discussion space organised by subject, where people publish messages and reply to contributions from other participants. Conversations are stored in threads, so they can be consulted and continued at different times.
Forums may be public or private and support different levels of participation. Registration, approval of new members and pre-publication review depend on each community’s rules; they are not requirements shared by every forum.
The terms bulletin board, online forum and discussion board are also used. Unlike a blog, where publication usually begins with one or more defined authors, a forum allows its members to propose topics and develop collective conversations within the available categories.

A forum usually supports asynchronous communication: one person publishes a message and others reply later. In a chat, conversation normally takes place in real time and messages are more immediate. Some platforms combine both models, so the distinction depends on how conversation is organised rather than technology alone.
A social network is primarily structured around profiles, relationships and streams of posts. A forum is organised around specific subjects and preserves thematic continuity more effectively, making earlier questions, answers and discussions easier to find.
How a forum works
The precise structure varies between communities, but forums commonly organise participation through several recognisable elements:
- Categories and subforums: They group conversations by subject or area of interest.
- Topics or threads: They contain an initial message and the replies related to it.
- Accounts and profiles: They identify members and may include an avatar, history, reputation or preferences.
- Permissions and moderation: They determine who can read, publish, edit, move or remove content.
Search, quoting, subscription and notification features let people follow activity without being connected when a message is published. Administrators and moderators enforce the rules, organise content and respond to spam or conflict, while netiquette describes the behaviour expected from participants.
Internet forum examples
Although many conversations have moved to social networks and messaging applications, forums remain useful for gathering specialist knowledge and maintaining searchable archives. Spanish-language examples include:
- Los Viajeros: A community devoted to destinations, routes and travel experiences.
- Burbuja: A forum discussing economics, housing and current affairs.
- HTCMania: A community focused on mobile devices and technology.
- Abandonware: A forum about classic video games and their preservation.
- Forocoches: A general-interest forum with many subject areas.
Forum software
A forum may operate as a standalone website or be integrated into a content management system. The choice of software affects administration, customisation, permissions and technical maintenance. Well-known options include:
- phpBB: Open-source software for installing and managing a standalone forum.
- MyBB: Free and open-source software with theme and plugin systems.
- bbPress: A plugin that adds forums to a WordPress website.
- vBulletin: A commercial platform for managing forums and online communities.
- Kunena: A forum extension designed for Joomla-based websites.
Search visibility
Community messages can answer specific questions and form an archive of user-generated knowledge. This content can attract specific searches when it is accessible, well organised and genuinely useful, but accumulating pages or messages does not guarantee visibility within an SEO strategy.
Profiles, signatures and forum replies were once widely used to insert links at scale. Google launched Penguin in 2012 as part of its efforts against manipulative link practices. Publishing messages solely to obtain backlinks is spam and may harm both the forum and the website being promoted.
Community moderation
The quality of a forum also depends on its governance. Moderation needs to address duplicate content, automated accounts, personal data, misinformation and abandoned conversations. Clear architecture, internal search and understandable rules help members and visitors find reliable information.
