YouTube is the world's most popular video sharing site, with over 90 billion videos viewed on the website each month. Set up in 2005, it now has localised interfaces for over 40 countries and delivers 2 out of every 5 videos viewed worldwide.

This service provides caption and script optimisation for your YouTube videos. Closed captioning and scripts produce subtitles that can help your hard-of-hearing or non-native viewers to understand what is being said on your video, and has the additional advantage of being readable by search engines. 

Video search engine optimisation brings important text and keyword components to the moving image so search engine indexes can more relevantly associate the image contents with textual keyword searches. It relies on optimisation techniques ideally during the planning of the video – including its crucial script— as well as during the production stage, through the more usual on-page SEO and off-site factors which encompass building suitable links and working with the YouTube community users, as well as channel signals for ranking on Google/YouTube.

Including a transcription has other advantages besides helping search engines manage the content; it's good for users and usability too. People who want to watch your video may not have the opportunity to do so at work or on the go, or even on a mobile if they're lacking a plug-in. The transcription helps them find important information and increases their ability to interact with your site.

The advantage of closed captioning is that crawlers can find and index that content – providing an important lever for the subsequent index and presenting relevant results in search engine results pages.

Quality process

The process begins by completing a briefing questionnaire with your account manager to clarify your objectives. This briefing will be visible to all the team members involved with delivering the project and is the foundation for all our quality checks.

Each set of video captions or script input is developed and worked on by a native speaker of the target language with experience in search marketing, under the supervision of an account manager, to optimise it most efficiently.

Webcertain Group is passionate about generating business growth for its clients in any part of the world.

A team of native speakers of all the world’s major languages works together to achieve client objectives - no one understands working with different cultures and the nuances of language in the globe’s search engines better than the Webcertain multilingual teams. Webcertain operates in 44 languages.
