1. SEO INTERVIEW
QUESTIONS

2.  Search engine optimization is a methodology of strategies,
techniques and tactics used to increase the amount of
visitors to a website by obtaining a high-ranking placement
in the search results page of a search engine (SERP) -
including Google, Bing, Yahoo and other search engines.
(OR)
 It is the process of getting traffic from the “free,”
“organic,” “editorial” or “natural” search results on search
engines.

3.  The simplest robots.txt file uses two key words, User-
agent and Disallow. User-agents are search engine robots
(or web crawler software); most user-agents are listed in the
Web Robots Database. Disallow is a command for the user-
agent that tells it not to access a particular URL. On the other
hand, to give Google access to a particular URL that is a child
directory in a disallowed parent directory, then you can use a
third key word, Allow.
 Google uses several user-agents, such as Googlebot for Google
Search and Googlebot-Image for Google Image Search. Most
Google user-agents follow the rules you set up for Googlebot,
but you can override this option and make specific rules for only
certain Google user-agents as well.

4.  The syntax for using the keywords is as follows:
 User-agent: [the name of the robot the following rule applies
to]
 Disallow: [the URL path you want to block]
 Allow: [the URL path in of a subdirectory, within a blocked
parent directory, that you want to unblock]

5.  The canonical form of a positive integer in decimal
representation is a finite sequence of digits that does not
begin with zero.
 More generally, for a class of objects on which
an equivalence relation is defined, a canonical
form consists in the choice of a specific object in each
class. For example, Jordan normal form is a canonical
form for matrix similarity, and the row echelon form is a
canonical form, when one consider as equivalent a matrix
and its left product by an invertible matrix.
 Canonical form can also mean a differential form that is
defined in a natural (canonical) way.

6.  “Fetch as Google” is an option available for webmasters to
check how a web page will be looking when Googlebot
crawls that page. This tool can be effectively used for the
following purposes:
 Troubleshooting webpages to improve the performance in
search engine result pages.
 Submitting pages for indexing whenever the content is
changed significantly.
 Finding out the pages causing issues when a site is
hacked by malwares.

7.  A site map (or sitemap) is a list of pages of a
web site accessible to crawlers or users. It can be
either a document in any form used as a planning
tool for Web design, or a Web page that lists the
pages on a Web site, typically organized in
hierarchical fashion.
 Sitemaps make relationships between pages and other
content components. It shows shape of information
space in overview. Sitemaps can demonstrate
organization, navigation, and labeling system.

8.  There are two popular versions of a site map. An
XML Sitemap is a structured format that a user
doesn't need to see, but it tells the search engine
about the pages in a site, their relative importance to
each other, and how often they are updated. HTML
sitemaps are designed for the user to help them find
content on the page, and don't need to include each
and every subpage. This helps visitors and search
engine bots find pages on the site. You cannot
submit an HTML sitemap in Google Webmaster Tools
as it is not a supported sitemap format.
