Metrix Ratings
Media Metrix,
the PC Meter Company, provides web site ratings
based on a sample of actual web surfers. It has
meters installed on the computers of about
12,000 home web surfers and 1,500 at work web
users. Information is then compiled to produce
its results.
Media Metrix
is the oldest, user-based ratings service on the
web. It has been providing results since
mid-1996. It merged with competitor Relevant
Knowledge in October 1998, and it competes with
NetRatings (see below).

Directory/Engine
This looks at
whether service is primarily an Internet
Directory (a collection of sites broken into
categories) or a Search Engine (an index of
catalogued sites that have been spidered) and
how the information is compiled.
Submission
Wait Time
This is the
average amount of time it takes from when a site
is submitted to be reviewed or indexed to the
time it takes to actually appear on the engine
or directory. This is assuming, of course, that
the submission was successful.
Support
Frames
This
indicates whether the search engine's spidering
software can navigate through a frames site and
index it.
Support
Metatags
This
indicates whether the search engine's spidering
software supports the keyword and description
(as well as others) metatags.
Deep
Crawl
This
indicates whether a search engine indexes only
the page submitted or whether it follows links
and indexes the entire site from the page
submitted.
