Question 4

True or False? When a site owner wishes to give instructions to web robots they place a text file called robots.txt in the root of the web site hierarchy (e.g. https://www.example.com/robots.txt). This text file contains the instructions in a specific format. Robots that choose to follow the instructions try to fetch this file and read the instructions before fetching any other file from the web site. If this file doesn't exist, web robots assume that the web owner wishes to provide no specific instructions, and crawl the entire site.

Question 8

True or False? The link structure of the web serves to bind all of the pages together. Links allow the search engines' automated robots, called "crawlers" or "spiders," to reach the many billions of interconnected documents on the web.Once the engines find these pages, they decipher the code from them and store selected pieces in massive databases, to be recalled later when needed for a search query.

Question 9

True or False? Search Engine Optimization (SEO) is the process of affecting the visibility of a website or a web page in a search engine's unpaid results -often referred to as "natural," "organic," or "earned" results.
