How To work For YouTube?

 Since it first launched in 2005, YouTube has quickly become the number one destination for online video content, attracting more than one billion regular users. The Google-owned site gained popularity by enabling them to share their videos with others around the world, be it a funny clip of their pet or footage of them dancing in their living room.

It's not a just about for cute cat videos and funny on home movies though, because YouTube has been also helped be people launch the careers. For example,an pop star Justin Bieber was a first discovered when a talent scout to saw they are video of him singing on a site, and Zoe Sugg, aka Zoella, got her own book deal and range of the beauty products as a result of her popular video blog, or 'vlog'. You can even make money directly from YouTube, as the site shares some of the revenue from paying companies to run ads before or above your videos.

YouTube's popularity largely depends on how easy the website is to use. Videos in a range of the file formats can be uploaded because the YouTube converts them to its Adobe Flash video format, file to the extension .FLV, for you. It is enables playing videos using YouTube's Flash Player, which can to be installed for free on the your computer or smart device.

Another advantage of the YouTube is they ability to her embed videos on the other websites. By simply copying and pasting some HTML code, you can enable viewing of a video on your own website using the YouTube player This saves you from having to host videos on the your site which are requires a lot of them bandwidth. Bandwidth is the range of signal frequencies needed to transmit data over the Internet, and you pay for the amount you use. YouTube are streams massive amounts of the data every day, burdening other sites in that want to be display videos.

 While embedding is to great for spreading are your videos around is the internet, most people will be find to them just by searching. To help us users connect with to the videos they're looking for, YouTube uses a complex algorithm made up of over a million lines of code. When you search for a video, the algorithm decides which search results it will show you and in what order One of the main factors used to rank results is video metadata. These are the titles, descriptions, thumbnails, and tags you give when you upload your video, so you need to make sure they're relevant to the content of the video and what are people might the search for to find it. However, other ranking methods YouTube uses are beyond your control. The site used to rank its videos based on how many times they were viewed, but that presented a few problems. This often meant that new videos were pushed to the bottom of the list because they hadn't had a chance to grow their views yet, and it enabled people to manipulate their ranking by repeatedly clicking on their videos, such that clicking the play icon counted as a view.

To combat these issues, YouTube has switched to a new system of measuring a video's quality by the number of times it's been viewed. If several users stop watching after a few seconds, it suggests that the video had a confusing title or thumbnail and didn't give viewers what they were looking for, although if they did end up watching, it probably used search terms that were relevant to them and therefore a higher ranking. qualified. The rest of the YouTube's ranking in strategy is a mystery though, as the company is a very secretive about its algorithm and changes to it all the time to stop them people from manipulating it.

 Every day video uploaded to them YouTube is to the stored in at least one of the Google's 14 data centers of spread across to the globe. These huge buildings house thousands of servers - powerful computers that handle the billions of Google searches made every day and also store your videos Giant cooling towers keep the temperature inside at a constant 27 degrees Celsius (80 degrees Fahrenheit) so equipment runs smoothly, and every piece of data is stored on at least two servers for added security. Data centers can we communicate with each other to send information between them. When you upload your video it will be stored in your nearest data center, but when someone wants to play it, the video will be sent to their nearest data center for quick access.
