F
faceted search
The combination of Boolean
operators and parenthesis. Faceted search allows for very specific,
powerful searches.
fake copy listing
The practice of stealing content from another
web site, republishing it and submitting
the duplicate page to the search engines
in a hope to steal traffic from the original
site. Apart from the obvious ethical problem, copyright legislation
is slowly adapting itself to the Internet, making it increasingly difficult
for thieves to steal content. The copyright holder may also appeal to
the search engine(s) that listed the duplicate page(s) and to the thief's
hosting company. It is advisable to display a clear copyright notice
(or a link to one) on every page of a web site.
false drop
A web page displayed in the SERP
that is not clearly relevant to the
query. The most common cause of false drops is words with multiple meanings.
If the query gives no indication of context,
the search engine has no way of predicting
which of the possible meanings the user has in mind. The term "argument",
for example, has different meanings in general use and in programming
jargon. Other possible causes of false drops include spamdexing
and bugs.
FFA
Free For All. Referring to web pages that contain
links to other pages and very little (or
nothing) else. The difference between FFA pages and directories
is that directories contain links to sites selected through some editorial
process, while FFA pages allow anyone to add a link to any page. For
a more detailed look at FFA pages and their dangers, please refer to
the Search Engine Yearbook.

Flash
Short for "Macromedia Flash"
A vector graphic animation technology that requires a plug-in but is
browser-independent.
flash page
See splash page.
FindWhat
www.findwhat.com
A popular PPC search engine.
frames
An HTML tag construct
that allows designers to display two or more web pages simultaneously.
The general perception is that frames can greatly improve site navigation,
but they are browser-dependant and not
search engine friendly. Most search
engines do not index framed pages correctly. For a more detailed look
at the problems with frames and possible solutions, please refer to
the Search Engine Yearbook.
frequency cap
A limit used in Internet advertising. It refers
to the maximum length of time or number of times a user will be exposed
to a specific type of advertisement.
fresh crawl
Google updates its
entire index of web sites once a month.
This is generally referred to as the Google
Dance. In an ongoing effort to make their results as relevant
as possible, Google introduced a fresh crawl that runs each
day. The idea behind the fresh crawl is to update pages that change
regularly. This allows Google to serve results that are up-to-date with
current events.

FUD
Fear, Uncertainty and Doubt.
The action of spreading fear, uncertainty or doubt. It is a fairly straight
forward but malicious technique that is typically used to negatively
influence the public perception of a competitor or his/her product.
full-text
search engine / full-text index
A full-text search
engine indexes every word on every document it spiders.
fuzzy search
A type of search
made possible by fuzzy matching. The search
engine returns results that it predicts will be relevant,
even when the terms used in the query does
not appear anywhere in the matched document.
fuzzy matching
As opposed to exact
matching.
Fuzzy matching attempts to improve recall
by being less strict but without sacrificing relevance.
With fuzzy matching the algorithm is
designed to find documents containing terms related to the terms used
in the query. The assumption is that related
words (in the English language) are likely to have the same core and
differ at the beginning and/or end. A search
for "matching", for example, would also return documents containing
match, matched etc. Unfortunately it will also return documents containing
unrelated words like matchbox etc.
