M
Magellan
A
discontinued directory. Once listing
only the very best of the best web sites, it was considered the "holy
grail" of SEO.
manual submission
The process of manually submitting a web page
to a search engine or directory
as opposed to using submission
software or a submission service.
Manual submission is considered by many to be the only reliable form
of submission, although some programs
and services have begun distinguishing themselves as viable options.
We discuss the two programs worth your money in the Search
Engine Yearbook.
mass submission
A service offered by submission
services whereby a page is submitted
to "thousands of search engines".
Most SEO specialists agree that mass submission
is not worth the time or money. In truth, there simply are not thousands
of search engines. There are about 5 that really matter and another
100-or-so worth knowing about (listed in the Search
Engine Yearbook). The rest of the "1000s" are usually
obscure directories or FFA
pages.
match
A match occurs when a document in the search
engine's index contains terms entered
as part of the query. The matching documents,
simply called matches, are then displayed on the SERP.
It's worth noting that search engines have different criteria for deciding
when a document is a match. Most search engines only require that one
word in the query match one word in the document. Some search engines
(like Google), require all words to appear
in the document before that document is considered a match.

partial word matching and Boolean
search
Match Driver
A system introduced by Overture
in 2002, it maps an advertiser's max bid on any form of a search
term to the terms that Overture deems to be related to the intent
of the searcher. What this means is that you can get traffic
from related terms you did not think of, but also that you could pay
for traffic you did not intend to target.
Metacrawler 
www.metacrawler.com
A popular meta search engine.
meta refresh
An HTML tag that is
used to reload or refresh the page after a specified interval, often
use to automatically redirect visitors
to another page. Most search engines
penalize pages that use meta refresh or any other type of automatic
redirection.
meta search
A search performed
on a meta search engine. MetaSearch
is also the name of a meta search engine found at www.metasearch.com.
meta search engine
A type of search
engine. Meta search engines usually do not maintain databases.
Instead, they query other search engines'
databases and return results from all of them - usually with a mention
of the search engine next to the each result. The Search
Engine Yearbook discusses meta search engines in more detail and
lists some of the more popular ones.
meta tag
An HTML tag placed
in the head section of a web page. The tag provides additional information
that is not displayed on the page itself. The initial idea was that
webmasters should use these tags to help search
engines index the page correctly by
providing an accurate description of the page content and a list of
keywords associated with the page. Unfortunately
this left the door open to abuse. Many webmasters used these tags to
gain an unfair advantage, forcing search engines to begin disregarding
meta tags. For a detailed how-to on meta tags and an updated discussion
on their importance (or unimportance) in SEO,
please refer to the Search Engine Yearbook.
Mining Company
Former name of the About.com
web directory.
mirror sites
Referring to sites that offer authorized duplicates
of content also found on other sites. The initial motivation was to
ease bandwidth load and increase availability by distributing popular
files to many servers. In the context of SEO,
the term is mostly used to refer to sites that attempt to deceive search
engines into indexing more than one
instance of a site by duplicating it on another server and domain.
Most search engines now have filters in place to detect mirror sites
and many of them penalize these sites by de-listing
both the original site and the mirror site.
Mosaic / NCSA Mosaic
An
early web browser developed by the National
Center for Supercomputing Applications (NCSA). It was the first cross-platform
browser, building on work done by Tim Berners-Lee. Mosaic became the
precursor to Netscape.

A term coined by Ken Evoy, referring to the aim
of a web site, for example, to generate a sale or to get the visitor
to subscribe to a newsletter.
mousetrapping / circle

button and the close button or using pop-ups that seem to multiply each
time the visitor closes one.
