Meta Tag |
At
the beginning of technology research, meta
tag maybe was the only information source
able for Search Engines to class and analyze
web pages and to give them visibility. Now
abundantly employed,
the meta are frequently slighted from
Search Engine's spiders, which making use
of new estimate rules. Saying first of all
that
however Meta have no one usefulness in
Directory positioning work,
html code inclusion remain a very important
step to put on-line the web site,
to not compromise the highest visibility
power ...
Meta Tag, contain specific
data writed in Html code. Is'nt needful
part of page, its lack don't alter
anything. Notwhitstanding its primary task
is offer data to Search Engine's spiders, exist
some Meta for other functions. Some allow
to refresh web page; others to redirect to
new Url after established second's number; its
is able to configure cookies,
graphics effects opening or closing page; in
short, its take pains ...

The Code |
Meta
Tag's place is between tag <Head>
and </Head>
Let's go to inspect
the most importants Markers:
It's
absolutely the most important in positioning
work, its inside keywords
frequency is first data in Search Engine
Estimate in order to award importance at
web pages and to organize the order by keywords. Omitting
this command, Search Engine will supply
at title automatic drawing up,
whit first 200 characters
following <body> excluding Html Tag.
- <Meta
Name="Title" Content="Your
Title">
This
Meta assign
a title at document but differently by
<Title> tag don't appeare in browser
window.
This
Meta assign
site description. This description will
be visualized
in Search Engines results; It's very important
that you don't exceed
300 characters and don't repeat keywords
exasperately to aviod spam.
This
Meta determine keywords wich should correspond the
user query in Search Engine, is important
here also don't repeat exasperately keywords, you
can employe comma amid keywords, leave out
"Case Sensitive"
factor why Search Engines to succeed in
consider
its in the same way.
Max Character Number is 300.
This
tag order at Search Engine Spider if
inspect or not the page. Most exactly: index/noindex indicate if the
page have to indexed in Search Engine database, follow/nofollow
indicate if the spider have to analyze linked
pages at this web page, "All"
is combination "index"+"follow".
Is possible to employe both,
for example "follow,noindex". A
page under construction, for example, where Search
Engine Optimization is not completed , don't
have indexed, else you would run the risk of
negative estimate. At any rate remember:
not all spiders respect your order ...
Tag "Archive/NoArchive"
allow Search Engines to save a page's copy inside
its cache memory. Search Engines save a
copy to allow the page visualization also
in case of temporary problems on web server. Cache version
have the same layout of latest indexed
version, consequently don't contain
latest revisions. This
Tag only oppose Cache copy ,
not the Search Engine estimate.
It's possible to address the command only
on specific Search Engine replacing command "Robots" with
Spider name; for example to oppose Google's
Cache copy:
<Meta
Name="GoogleBot" Content="noarchive">
- <Meta
Name="Pragma" Content="no-cache">
Tag Pragma, indicate
to browser if to save
or not site contents on pc cache memory, in
order to quicken page open. If your page is
frequently modified, it's profitable to
active "no-cache".
- <Meta
Name="Revisit-after" Content="15
days">
This
Tag ask at spider for new visit at regular
intervals of "Content=???;" days.
(Very little chance)
- <Meta
Name="Copyrightr" Content="Copyright.Author.2003
">
Indicate
the Author and site Copyright.
- <Meta
HTTP-EQUIV="Expires" Content="Sun,
31 Jan 2004 21:30:00 GMT">
Indicate
at Browser the page expiration date.
- <Meta
HTTP-EQUIV="Set-Cookie" Content="cookievalue=xxx;
expires=Sunday,31-jan-04 21:30:00 GMT;
path=/">
Configure
a cookie imputing it expiration date.
- <Meta
HTTP-EQUIV="Refresh" Content="2">
Refresh
the page every "Content=???;"
seconds.
- <Meta
HTTP-EQUIV="Refresh" Content="2;
url=page.html ">
Redirect
the browser at selected page.
(Optimization
result dubious - not advised)
How
indicated before, it exist another meta
tag only for graphical effects inside the
page:
- <Meta
HTTP-EQUIV="Page" Content="revealTrans(Duration=x,
Transition=x)">
To
obtain different effects, it suffice to
replace the variables , for exampe to obtain
effect on page load or on page close, it
suffice to replace "Page"
with "Page-Enter" or "Page-Exit"; moreover,
varying command "Duration e
Transition" you can obtain different
effects. Time in seconds.
Its
Exsist others meta tags, we have only analyzed
the most employed. The only necessary in
Search Engine Optimization arent Tags <TITLE><DESCRIPTION>
And <Robots> for spider authorizations, hardly Tag <KEYWORDS>.
