Social Sharing and Comments: If you're on social media, you're probably familiar with sharing and commenting. Social shares and comments are good indicators of how relevant your content is with your target audience. If a viewer watches your video and takes the time to share it with their network, you probably created a great piece of content. Social shares are also important because the more times your video is shared, the more it'll be viewed. If your goal is to reach a lot of people, social shares is a good metric to track.
White balance tells your camera the color temperature of the environment you're shooting in. Different types of light have different colors. For example, incandescent bulbs (like what many people put in a lamp) have a very warm color. The fluorescent lights (if you're reading this in an office, look up) are a little bit cooler. Daylight is cooler yet. Before you begin shooting, you have to adjust your camera's white balance according to your setup. Search Engine Optimization (SEO)
The ad auction process takes place every single time someone enters a search query into Google. To be entered into the ad auction, advertisers identify keywords they want to bid on, and state how much they are willing to spend (per click) to have their ads appear alongside results relating to those keywords. If Google determines that the keywords you have bid on are contained within a user’s search query, your ads are entered into the ad auction. Search Engine Optimization (SEO)
Many blogging software packages automatically nofollow user comments, but those that don't can most likely be manually edited to do this. This advice also goes for other areas of your site that may involve user-generated content, such as guest books, forums, shout-boards, referrer listings, etc. If you're willing to vouch for links added by third parties (for example, if a commenter is trusted on your site), then there's no need to use nofollow on links; however, linking to sites that Google considers spammy can affect the reputation of your own site. The Webmaster Help Center has more tips on avoiding comment spam40, for example by using CAPTCHAs and turning on comment moderation. Internet Marketing

When it comes time to shoot, clear out unnecessary people from the room and turn off the overhead lights. With your three-point lighting setup, there will be no need for those harsh fluorescents. When — and only when — everything is set up, call in your talent. There's nothing worse than being nervous, and then having to anxiously watch as lights are turned on and the camera is tested.
