Test for Search Engine competency.

Q: The robots lockout standard, also known as the robots lockout protocol or robots.txt protocol, is a standard used by websites to communicate with web crawlers and other web robots.
- True
- False
A: False
If wrong: The robots exclusion standard, also known as the robots exclusion protocol or robots.txt protocol, is a standard used by websites to communicate with web crawlers and other web robots. (See http://en.wikipedia.org/wiki/Robots_exclusion_standard)

Q: The robots exclusion standard specifies the instruction format to be used to inform the robot about which areas of the website should not be processed or scanned.
- True
- False
A: True

Q: 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.
- True
- False
A: True
If wrong: (See http://en.wikipedia.org/wiki/Robots_exclusion_standard.)

Q: Marking an area of a site "out of bounds" with robots.txt guarantees exclusion of all web robots.
- True
- False
A: False
If wrong: Despite the use of the terms "allow" and "disallow", the robots exclusion standard is purely advisory. It relies on the cooperation of the web robot, so that marking an area of a site "out of bounds" with robots.txt does not guarantee exclusion of all web robots. (See http://en.wikipedia.org/wiki/Robots_exclusion_standard.)

Q: To cause a webpage to perform better in search engine listings, the most important content should be in Flash files.
- True
- False
A: False
If wrong: To cause a webpage to perform better in search engine listings, the most important content should be in HTML text format. Images, Flash files, Java applets, and other non-text content are often ignored or devalued by search engine crawlers. The easiest way to ensure that the words and phrases you display to your visitors are visible to search engines is to place them in the HTML text on the page. (See http://moz.com/beginners-guide-to-seo/basics-of-search-engine-friendly-design-and-development.)

Q: Search engines have two major functions:

1. crawling and building an index, and
2. providing search users with a ranked list of the websites they've determined are the most relevant.
- True
- False
A: True

Q: 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.
- True
- False
A: True

Q: For most popular search engines, when a person performs an online search, the search engine begins crawling the web and returning a list of all connected hyperlinks that are encountered.
- True
- False
A: False
If wrong: For most popular search engines, when a person performs an online search, the search engine scours its corpus of billions of documents, (which was created earlier by crawling and indexing web sites) and does two things: first, it returns only those results that are relevant or useful to the searcher's query; second, it ranks those results according to the popularity of the websites serving the information. It is both relevance and popularity that the process of Search Engine Optimization is meant to influence. (See http://moz.com/beginners-guide-to-seo/how-search-engines-operate.)

Q: Search engines typically assume that the more popular a site, page, or document, the more valuable the information it contains must be.
- True
- False
A: True

Q: One of the main contributions to improved search engine performance, developed by Brin and Page, was PageRank.
- True
- False
A: True
