Content - The information located on a web
page. This includes text, images, and any other types of
information that a webmaster places on the page.
Counter - A script that counts the number of hits, unique
visitors, and/or page views that a web page (or an entire
site) receives. These "stats" provide very useful information
for the webmaster.
Crawler - A program used by search engines to "crawl" the web
by following links from page to page. This is how most search
engines "find" the web pages that they place in their index.
Also referred to as a spider or robot.
Crawling The Web - Search engines use crawlers to move from
web page to web page by following the links on the pages. The
pages "found" are then ranked using an algorithm and indexed
into the search engine database.
Cross Linking - This is where the owner of two or more
websites interlink the sites in order to boost their search
engine rankings. If detected, cross linking often results in a
search engine penalty.
Comment Tags - Used in a web page's HTML source code to
indicate certain information about a section of the page code.
Some search engines will consider keywords contained in
comment tags for keyword density purposes, others (including
Google) will not.
Example:
<!--This is a comment-->
Click-Through - The action of clicking on a
link to visit a web page.
Click-Through-Rate (CTR) - The number of times a link is
clicked on divided by the number of times that same link is
displayed (called an impression).
Example:
A link is displayed 100 times (100 impressions) and clicked
on 7 times. The CTR is 7% (7/100=.07).
Cloaking - Serving one version of a page to a human visitor
and a different version of the same page to the search
engines. This is usually done to "fool" the search engines
into giving the page a higher rank than it would normally
receive while making sure the human visitor sees a useful and
attractive page.
Note: Cloaking is discouraged by most major search engines,
including Google.
