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 florescent lights (if you're reading this in an office, look up) are a little bit cooler.

Since social media marketing first came to be, strategists and markets have been getting smarter and more careful with the way they go about collecting information and distributing advertisements. With the presence of data collecting companies, there is no longer a need to target specific audiences. This can be seen as a large ethical gray area. For many users, this is a breach of privacy, but there are no laws that prevent these companies from using the information provided on their websites. Companies like Equifax, Inc., TransUnion Corp, and LexisNexis Group thrive on collecting and sharing personal information of social media users.[107] In 2012, Facebook purchased information from 70 million households from a third party company called Datalogix. Facebook later revealed that they purchased the information in order to create a more efficient advertising service.[108]

Google and other search engines may be calculating their rankings using social media presence as a significant factor, because of the fact that strong brands almost always use social media. As such, being active on social media could act as a “brand signal” to search engines that your brand is legitimate, credible, and trustworthy. That means, if you want to rank for a given set of keywords, having a strong social media presence could be almost mandatory.

Therefore, they expected a seamless user experience across different channels for searching product's information. The change of customer behavior improved the diversification of marketing technology.[18]
