网络营销/电子商务词典：搜索引擎/互联网基础应用相关词汇（H）
【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。
hand submission
The practice of visiting each search engine and directory
and submitting the registration form by hand as opposed
to using a software program. Some systems will not accept
automated submissions.
heading / heading tag
An HTML tag of 6 sizes. The syntax is <H1></H1>,
<H2></H2> etc., with H1 being the largest. Heading
tags have significance in SEO. Search engines normally assign
more weight to documents where the keywords used in the
query are found inside heading tags. Pages that use heading
tags generally rank higher, but excessive use might get
the page de-listed. For more SEO techniques and the complete
do's and don'ts of SEO, please refer to the Search Engine
Yearbook.
hierarchical clustering
Clusters or groups (of search results) organized into a
hierarchy or tree structure instead of a flat list of clusters/groups.
hidden text
Text on a web page designed to be visible to spiders but
not to human visitors. The aim is to load the page with
keywords without deterring from the visitor's experience.
Of the various techniques of hiding text, the most common
is to set the text color to exactly or nearly the background
color. Most search engines can now detect hidden text and
consider it a form of spamdexing. Pages that contain hidden
text are penalized or even de-listed. For more on hidden
text and the dangers of using hidden text, please refer
to the Search Engine Yearbook.
hit
One hit is one request for a file on a web server. A visitor
opening a page with 5 images will in the process generate
6 hits (1 each for the images and one for the HTML page
itself). The term is sometimes also used with reference
to the number of results (hits) a search engine returns
for a specific query.
Hits are often confused with page views and unique visitors.
Also see log file
hit-and-run page
A page that gets many hits (traffic) and quickly disappears
again.
HITS
Hyperlink Induced Topic Search. Referring to a search where
the search algorithm relies (partly) on hyperlinks to identify
topic areas. Not to be confused with "hits" referring
to file requests.
homepage / home page / home
The main "index" page or navigation hub of a web
site. The homepage is not necessarily the first page. Many
sites use splash pages to welcome visitors and lead them
from there to the homepage. At most search engines you can
simply submit your homepage and leave it to the spider to
crawl the rest of the site from there.
Hotbot
www.hotbot.com
A fairly popular search engine, although its popularity
has declined sharply as Google rose to dominance. Hotbot
was once reported to have the largest database of them all.
In a study by Pandecta Magazine (4th quarter of 2002) it
was estimated to have the 4th largest database after Google,
AllTheWeb and Wisenut. HotBot exploits NOW (Network Of Workstations)
parallel computing technology in order to achieve both speed
and size. NOW is basically interconnected workstations and
LANs. When you add up the combined computing power of those
smaller components, you get supercomputer-class performance.
For more on Pandecta Magazine's comparative study, a more
detailed look at Hotbot and all the other search engines
worth knowing about, please refer to the Search Engine Yearbook.
hot linking
The practice of displaying images files, video files etc.
on a web site when those files are on another (usually someone
else's) server. Effectively the site displays content that
uses up someone else's bandwidth. Hot linking is generally
considered unethical unless prior permission is obtained.
HTML
Hypertext Markup Language. HTML is the primary language
used to create web sites.
HTTP
Hypertext Transfer Protocol. HTTP is the most common transfer
protocol used to facilitate communication between servers
and browsers.
hub
Coined by Jon Kleinberg during the development of his HITS
algorithm. Hubs are sites that link to many other sites
that are cosidered authorities in their topic area. For
instance, the Ford Motor Company's web site is an authority
in the car manufacturing topic. So is Ferrari's web site
etc. A site that links to all these manufacturers would
be considered a good hub within the car manufacturing topic.
Also see authority.
hyperlink / link
Clickable content on a web page usually leads to another
page, another site or another part of the same page. The
clickable content therefore is said to link to the other
page / site / part of the same page. Spiders use links to
crawl from one page to the next as they index web sites.
Hyperlink Induced Topic Search
See HITS.
