【说明】：下列词汇为网上营销新观察通过多个网站的相关资源整理汇总，并未一一核对词汇内容的准确性，对词汇的解释不代表本站的观点，仅供初步参考，如需要严格考证词汇的意义，请参考互联网相关的专业词典。
obfuscation
A seldom-used term, more often called spamdexing. It refers
to the misrepresentation of meta tags and page content in
order to gain an unfair advantage in the search engines.
The term is sometimes differentiated from spamdexing in
that it is used to refer to pages that, through stealth,
rank highly although they are poorly optimized. The idea
is to deliberately mislead others who might steal the page.
ODP (Open Directory Project) / DMOZ
dmoz.org
A massive directory continually expanded by volunteers.
What sets this directory apart is that it makes its database
of indexed documents available to other directories &
search engines. A listing here results in the page automatically
being listed in many other directories and search engines.
The model of using volunteer editors is fairly ambitious
- and surprisingly successful. It is a mammoth achievement
and an asset to the online world. Getting a site indexed
at ODP can be difficult, so we've included comprehensive
guidelines and a full review of this directory in the Search
Engine Yearbook.
off the page / off the page factors / off the page criteria
Those factors that impact the ranking of a web page but
that are not located on the web page itself. Inbound links,
anchor text etc. are examples of off the page factors.
ontology
In the context of search engines it refers specifically
to a file that defines relationships between words.
Also see fuzzy matching.
Open Directory Project (ODP)
See ODP
Open Text
www.opentext.com
A fairly large directory listing only business sites.
operators
"AND", "NOT" and "OR" as used
in Boolean Searching.
optimize / optimization
A page is said to be optimized when it has been structured
in such a way that it ranks well (on the SERPs) for those
keywords it targets. It is a fairly subjective concept.
What some see as optimization might be termed spamdexing
by others. In the strictest sense, optimization means simply
making a page spider-friendly by, for example, using text
links rather than image links. In the SEO industry the term
is more often used as a collective name for all the "tricks"
webmasters use to improve a page's ranking.
origination page
According to Chris Sherman's "New Web Map Reveals Previously
Unseen 'Bow Tie' Organizational Structure", origination
pages are typically new or obscure pages that haven't yet
attracted interest from the larger, more inter-linked web
community, or that are only linked to from other origination
pages.

outbound link
When site A links to site B, site A has an outbound link
and site B has an inbound link.
Overture
www.overture.com
The largest and most popular of the PPC (pay-per-click)
search engines. Formerly known as Goto. For an in-depth
look at Overture and different PPC strategies, please refer
to the Search Engine Yearbook.
