【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。
packet sniffing
The practice of monitoring pieces of data (called packets)
as they move over the Internet.
page impression
See page view
page jacking / pagejacking
The act of duplicating a (usually high ranking) web page
and presenting the duplicate as the original. This kind
of blatant theft is fairly uncommon. In most cases the legitimate
author / owner can easily prove ownership of the material.
page popularity
See link popularity
PageRank
Google's measure of the link popularity of a page. For a
more detailed look at PageRank and how to maximize yours,
please refer to the Search Engine Yearbook.
PageRank hoarding
The practice of getting as many inbound links as possible
while giving as few outbound links as possible. This is
done in attempt to increase PageRank / link popularity.
Regarded as spam.
page view / page impression / page request
Often confused with a hit, the term refers to the actual
number of pages (not files) viewed by all visitors to a
site in a given time period. The number of page views (and
other statistics) can be obtained through log file analysis.
paid listing
A listing on a SERP that is achieved through outbidding
competitors (as in PPC). The term is sometimes also used
to refer to keyword-targeted advertisements, where the advertiser
pays the search engine a fixed amount to have its ad shown
on the SERP for a specific keyword.
parentheses
Some search engines allow users to use parenthesis ( ) to
group words. This is especially useful in Boolean searchers.
partial word matching
Some search engines will consider not only exact matches,
but also partial matches. This means that if the search
term is contained within a word in a document in its index,
the search engine considers the document a match. It's not
as complicated as it sounds though. If the user enters "word"
as the query, the search engine will consider a document
a match if it contains word or wordiness or foreword or
MSWord etc. So the search term should be contained in the
word.
Also see begins-with partial word matching.
pay per click
See PPC
pay-per-click search engine
See PPC search engine
pay per lead
See PPL
pay per view
See PPV
personally identifiable information
Referring to information collected by a web site that can
be used to identify a user. It does not refer to usernames
or nicknames, but rather to information like real names,
telephone numbers, physical addresses etc.
phrase search
A search for documents containing an entire phrase - as
opposed to one or more keywords. The important distinction
here is that in a phrase search, the words has to appear
side by side in the document (exactly as in the query) for
that document to be considered a match. If the words appear
scattered or they appear side by side but in the wrong sequence,
it is not considered a match. Phrase searching can be done
on most search engines by simply enclosing the phrase in
quotation marks.
placement
See positioning
politeness window
Most spiders will not crawl an entire site in one session.
Instead, they crawl a couple of pages and return after a
day or two to crawl a couple more and so on until they have
indexed the entire site. This is a self-imposed limit in
order not to overburden a server. These gaps between sessions
are collectively known as the politeness window. Nice spiders.
pop-under / popunder / pop under
A supposedly less annoying variation of the pop-up. It creates
a new browser window, usually containing an advertisement
that is displayed behind the current window. The user then
only sees the pop-under when the current window is closed
or minimized. In truth, many users find pop-unders as annoying
as pop-ups, with the added irritation of feeling tricked
into not closing the new window immediately.
pop-up / popup / pop up
A new browser window (usually containing an advertisement)
automatically opened when the users performs a specified
action - like opening a page, clicking a link, closing a
page etc.
Also see pop-under.
portal
A web site that functions as a kind of starting page or
entry point to the web. Portals typically have a wide variety
of features such as search, free web-based e-mail, news
etc. Well-known examples include Excite and Yahoo.
portal page
See gateway page
portal site
See portal
positioning
Often used as a synonym for optimization.
postcoordination of terms
The use of 2 or more single words to describe a document.
A page about herbal cures for common ailments, for example,
could be indexed under "herbal", "cures"
and "remedies". The search engine would then consider
that document a match to a query like "alternative
remedies".
PPC
Pay-Per-Click. An advertising payment model where the advertiser
pays only when the advertisement is actually clicked. In
other words, the advertiser literally pays only for visitors
rather than per advertisement impression. The term CPC (cost
per click) is sometimes used in the place of PPC and the
plural PPCs is sometimes used to refer to PPC search engines.
PPC search engine / PPCSE
A search engine that uses the PPC (pay per click) payment
model, also known as the CPC (cost per click) model. Advertisers
bid on keywords they wish to target. The search results
are then ranked based on the bids with the highest bidder's
site ranked first. Advertisers only pay when their links
are clicked - not every time their sites appear in the results.
PPCSE marketing has become a fairly important and potentially
effective online marketing technique. We take a look at
some of the important PPC search engines (like Overture)
and reveal some top PPC strategies in the Search Engine
Yearbook.
PPL
A system where the receiving site pays a certain amount
to the referring site for every new lead.
Also see PPC.
PPV
Pay per visit. Same as PPC only the term "visit"
is used instead of "click".
precision
Search engines will often consider a document a match to
a query when that document is not really relevant to the
query. These mistakes happen because search engines, to
a certain extent, have to "guess" what the user
is looking for - especially when words used in the query
have double meanings. Search engines must find a balance
between recall (it's ability to find all relevant documents)
and precision (it's ability to find only relevant documents).
The aim in information retrieval is to get both recall and
precision spot-on. In other words to return all relevant
documents and nothing else. In the real search engine world
however, it is often a trade-off. Precision is scored by
dividing the total number of pages found by the number of
relevant pages found. For example, if 1000 documents are
found and 770 are relevant, the search engine's precision
is 0.77 or 77%.
precoordination of terms
The use of compound terms to describe a document. A page
about herbal cures for common ailments, for example, could
be indexed under "herbal remedies".
PR0 / PR zero
PageRank zero. A penalty (rumored to be) imposed by Google
on sites caught spamdexing. It's worth noting that Google
denies having such a penalty.
probabilistic model
Referring to any search engine model that matches documents
to a query based on the probability that a document will
be relevant to a query.
promotion
In the context of search engines it refers to submitting
of the site information with the intent of getting the search
engine to list the site.
proximity
See adjacency
proximity search(ing)
In proximity searching the user can specify a maximum distance
between keywords. For example, in a search for "guns
roses" with a maximum distance of 2, documents containing
the following are considered matches:
- guns and roses
- guns 'n roses
- more guns than roses
While these are not:
- …used guns, but in the next example André used roses
- Guns blazed in the rose garden
Ok, bad example. It's worth noting that some search engines
also let you define the order, so "roses and guns"
does not count as a match.
