PPI: (Pixels Per Inch)

A pixel is the smallest unit of a digital image or graphic that can be displayed and represented on a digital display device. A pixel is the basic logical unit in digital graphics. Pixels are combined to form a complete image, video, text, or any visible thing on a computer display.
PNG: (Portable Networks Graphic)
A PNG (Portable Networks Graphic) is an image format.

Facebook gathers information from large consumer databases and on top of that, tracks people outside of the social platform, which in return allows advertisers to go quite far in terms of targeting. To give you an idea of how much these companies know about us, some consumer databases like Acxiom have an average of 1,500 data points per person!
It is the number of clicks it takes to reach a page when starting from the home page. For example, if it takes two clicks to get to the “About us” page, then its page depth is 2. It has been proven that the deeper the page, the less likely Google will crawl it. Uncrawled pages will therefore not be added to the index, and will not be able to rank on Google.
This is a SEO metric and a component of Google’s algorithm. Google basically evaluates the importance of each page, and then gives a score between 0 and 10. The score given is a reflection of the number of links to each page, and their quality.Read a bit more...
