Adult tube site & CMS glossary
Clear, jargon-free definitions of the terms you will meet when launching and running an adult tube site — from the software and SEO words to the monetization and compliance ones.
- Adult tube site
- A video site laid out like a "tube" — a grid of thumbnails with categories, tags and search — for adult content.
- Adult tube CMS
- The software that runs an adult tube site: video import, ranking, the player, the member zone, ads and SEO, all in one application.
- Tube script
- Another name for an adult tube CMS — the script or software package that powers a tube site.
- Self-hosted
- Software you install and run on your own server and fully control, as opposed to a hosted SaaS you rent.
- Source-available
- Code you can read and modify, even when it is not released under a formal open-source license.
- Encoded code / ionCube
- Source that has been scrambled so it cannot be read or edited; KVS and several paid scripts ship ionCube-encoded by default.
- KVS (Kernel Video Sharing)
- The established, paid, ionCube-encoded adult tube script and the market reference point.
- CTR ranking
- Ordering videos by click-through rate so the thumbnails people actually click rise to the top automatically.
- Bulk / mass import
- Adding many videos at once from a CSV or JSON file instead of entering them one by one.
- Grabber
- A scraper that pulls videos from other sites — legally risky compared with publishing a licensed catalogue.
- Licensed catalogue
- A library of content you are licensed to publish, as opposed to scraped or grabbed material.
- Transcoding
- Converting uploaded videos into multiple web-ready qualities (for example 360p, 480p, 720p, 1080p).
- FFmpeg
- The open tool most tube sites use under the hood to transcode and process video.
- CDN
- A content delivery network that caches your videos close to viewers to cut latency and offload bandwidth.
- Bandwidth
- The volume of data served to viewers; for video sites it is usually the largest cost at scale.
- Storage backend (S3 / FTP / SFTP / WebDAV)
- Where a CMS keeps and serves media files; a good CMS supports several so you can pick the cheapest that performs.
- Member zone
- Logged-in user features such as accounts, favorites, watch history, likes and comments.
- Taxonomy (category / tag / performer)
- The entities a tube site uses to organize and cross-link videos so visitors can browse.
- VAST
- Video Ad Serving Template, the industry standard for serving in-player video ads such as pre-rolls.
- Pre-roll
- A short video ad shown before the content plays, usually delivered via VAST.
- Pop-under
- An ad window that opens behind the current page — a common adult-traffic monetization format.
- AVOD
- Advertising-based video on demand: free-to-watch content funded by ads, which is the classic tube model.
- Age verification
- Confirming a visitor is of legal age before showing adult content, increasingly required by law in the US and UK.
- 2257
- US record-keeping law (18 U.S.C. 2257) requiring proof of performer age and identity for adult content.
- DMCA
- The US copyright takedown framework; a compliant site publishes a process and registers a designated agent.
- Watermark
- A logo or text overlaid on videos to brand them and deter theft.
- Sitemap
- An XML file listing your URLs so search engines can discover and crawl every page.
- Canonical URL
- The single preferred URL for a page, which tells search engines which version to index and rank.
- hreflang
- A tag that tells search engines which language or region version of a page to show each user.
- JSON-LD / Schema.org
- A structured-data format (and vocabulary) that describes your pages to search and AI engines, e.g. VideoObject.
- Crawl budget
- How many of your pages a search engine will crawl in a given period — a finite resource on large sites.
- Duplicate content
- Identical or near-identical pages that split ranking signals; fixed with canonicals and unique text.
- 301 redirect
- A permanent redirect that sends an old URL to a new one and passes its ranking equity across.
