The purpose of this document is to
provide you with background information on search engine technology and some
Tips on how to get your Web site to appear on the result pages of search engines
and directories. We are by no means promising any miracles. However, this
information will help you better understand search engines and directories and
will hopefully serve to put you in a better position than you currently are in
now.
1. What is
a search engine?
Search engines utilize indexing
software agents often called robots or spiders. These agents are programmed to
constantly "crawl" the Web in search of new or updated pages. They
will essentially go from URL to URL until they have visited every Web site on
the Internet.
When visiting a Web site, an agent
will record the full text of every page (home and sub-pages) within the site. It
will then continue on to visit all external links. Following these external
links is how search engines are able to find your site regardless of whether or
not you register your URL with them. Submitting your URL, however, does speed up
the process. It notifies an agent to visit and index your site instead of
waiting for it to eventually locate you through one of your external links.
Robots will then revisit your site
periodically to refresh the recorded information. The revisiting of links is the
reason why some search engines don't require you to inform them of dead links.
Eventually, their robot would try unsuccessfully to update the information on a
dead link and realize it no longer exists.
Finally, an easy way to tell whether
a Web index is a search engine as opposed to another type of directory is by the
information it requires when adding your URL. A true search engine will only
need the Web address. The indexing agent takes care of the rest.

2. How do
search engines differ from directories, announcement sites, and guides on the
Web?
Directories:
The main difference between a search engine and a general directory is that a
directory will not list your URL if you do not register it with them. They do
not make use of indexing software agents and so have no way of knowing it's out
there. As a result, their registration form will be considerably longer than
just your URL. Directories are usually subdivided into categories and you have
to submit your URL under the most appropriate heading.
Announcement Site:
The explosion of sites being added daily to the Web has created a need for
announcement sites that track all of the new sites that join the Internet.
Announcement sites are not only useful for Webmasters and marketers to kick-off
their online promotion campaign, but also for users to keep current on what's
happening with the WWW. Depending on the announcement site, different Internet
documents can be announced -- new web pages, new articles as well as new
resources. The time period policy also differs from announcement site to
announcement site, but all "announcements" are posted for a temporary
period of time. Once removed from the What's New section, most announcement
sites archive these pages so users can continue to access them.
Guides & Cool Sites:
Guides are quickly becoming an important source for finding interesting and
useful sites on the Web. In general, Guides review and rate only a small
percentage of all sites submitted. Therefore, make sure your site is
"rate-worthy" before posting. Most of the guides allow reviewed sites
to use their special icons as a sign of quality. Cool sites usually select one
new Web site every day. Getting selected as a cool site will attract high
traffic, but that traffic will usually only be experienced for a temporary
period of time.

3. General
Tips for Getting Listed in Search Engines
Each search engine looks at
different elements of your page, therefore we highly recommend implementing as
many of these Tips as possible.
a. Use keywords in
the <TITLE> of your document making it as descriptive as possible. When
visiting your site, an agent will go first to the <TITLE> tag. For
clarification purposes, the <TITLE> tag is what a browser will display in
its title bar and is not simply the first line of HTML that shows up on your
page. (Although your first words of introductory text should be descriptive as
well). Search engines will display the text located between the <TITLE>
tags when your web page is listed in a search. By making your <TITLE>
descriptive, you'll be better off than those who only have keywords within the
text of their page. It will also be helpful when people bookmark your web site.
If a more descriptive name appears in a person's hotlist, it will be easier to
find your site at a later date.
For example, instead of using
<TITLE> Suncorp </TITLE> as the title of Suncorp's home page,
<TITLE> Suncorp: Tanning Supplier </TITLE> would be much more
descriptive. It would also place greater emphasis or relevancy on "Tanning
Supplier" when calculating keywords.
b. Descriptive Page
Text Search engines assign greater relevancy to text located at the top of a
page than to text located in the middle or at the bottom of the page. The search
engines assume that web page authors will present their most important
information first. If your page has a main graphic at the top, you should place
some descriptive text either underneath or beside the image. The search engines
will index this text and assign it a high level of relevancy.
c. Use <META>
tags which allow you to provide even more detail about your Web pages and
thereby gain greater control over how your pages are indexed. Not all search
engines make use of <META> tags, but adding these tags to your pages will
make them more accessible to the search engines that do.
<META> tag codes are inserted
within the <HEAD> </HEAD> tags. The basic syntax is:
<META
name="description" content="a health and fitness center located
in Atlanta">
This will control what appears as the
summary of your Web page and will be displayed after the title of your document
in the index listing. The content of the description should clearly convey what
one can expect to find when linking to your site.
<META
name="keywords" content="running, weight control, nutrition,
aerobics, cholesterol, Georgia">
This will allow you to provide extra
information about your page to the search engines without it being visible to
the reader. While search engines do take these keywords into account when
indexing your page, they are still going to index the entire contents of your
page as many sites do not include <META> tags. Since this is the case,
there is no need to be redundant. Include keywords that will not necessarily be
derived when a robot visits your site. In other words, "health" and
"fitness" need not be included in your list of keywords as it is part
of your <TITLE>. Robots index both the description and keyword
<META> tag contents as searchable words. Hence, your site will come up in
a search if someone typed in "nutrition" or "health center"
from your description. One way to maximize the usefulness of keywords is to
incorporate singular and plural cases of words as well as active and passive
verbs. For example, diet, diets, and dieting will yield similar but somewhat
varying results in a search. Since you're able through tags, why not guarantee
you come up on all of them.
Do not, however, excessively repeat
keywords in a keyword <META> tag as search engines may penalize you for
this. At present, InfoSeek and Lycos are two such examples and others may adopt
similar policies in the future. The penalty will most likely be the spider
disregarding the <META> tag and extracting keywords from the content of
your page- as is usually the case. However, some Submit It! users have reported
being dropped from a search engine's database and felt keyword repetition played
a role in the removal of their listing.
Who should definitely make use of
<META> tags?
Sites using Netscape frames:
The main HTML file contains the <FRAMESET> tags, but fails to provide
robots with any real useful information for selecting a Web site's abstract.
Therefore you should include a description summarizing the contents of the
frames on your page with <META> tags.
Sites using Javascript at the
top of their page:
If JavaScript code makes up the first several hundred characters on your page,
you should use <META> tags to provide a description for your page. An
indexing agent's search logic is programmed to place more emphasis on the text
located at the top of your page than the content it combs through towards the
bottom.
d. Use ALT tags
especially if your site contains multiple photos or graphic-image maps at the
top of your home page. Some search engines will take into account the text
within an ALT tag when creating your site's description and keywords. In
addition, you will be greatly appreciated by all people who visit your site with
their Auto Load Images option turned off or by those who prefer to use character
browsers.
ALT tags are placed after an image
file and generally look like the following:
<img src="/images/submits.gif"
alt="Submit It! : Web site marketing services and tools.">
e. If
your site utilizes frames, you should be aware that search engines
treat frames as if they are links within your main page. As a result the engines
will review and index your main page and, at a later date, return to index each
individual frame just as it will return to index all other internal links within
your web site. Therefore, in order to have your main page (typically titled
index.htm or ) indexed accurately and efficiently, we recommend that you add
some descriptive text between the <noframes> and </noframes> tags of
the HTML source coding of your main page. The noframes tags are usually placed
below your frame set information. The frame set information is designated by
<frameset> and </frameset>. This text should include your most
important keywords and keyword phrases. Adding this text will provide the search
engines with content from which to derive keywords for indexing. After this
change has been made to your Web site, the page itself will appear exactly the
same to anyone using a browser that supports frames. However, users of browsers
that do not support frames (i.e. Netscape 1.0 or lower) will now be able to
successfully view your home page.

4. Indexing
Characteristics Specific To Individual Search Engines
Excite
At the present time, Excite does not make use of <META> tags. Since
keywords and summaries are automatically generated by Excite, you have less
control over their creation. However, there are still a few things you can do.
Excite's software looks for common
words or themes within a page. It then selects sentences for the summary that
either contain these words or convey the overall theme. The words within these
sentences are also used as keywords for which the site can be searched.
- Especially at the beginning of
your page, be as concise as possible and limit non-descriptive sentences. If
the Excite robot comes across a number of ambiguous phrases, it will have to
look deeper and deeper into your site to determine its theme and site
summary. Along the same line, too little text will also force the robot to
travel further into the site for more information in order to establish a
theme.
- Excite's indexing software places
preference on complete, punctuated sentences. If you have content, such as a
quote, at the top of your page that you do not want Excite to include in
your site summary, do not display it as a complete sentence. This will
lessen the chance that the quote will be included, but will not guarantee
its exclusion.
HotBot / Inktomi
- HotBot supports both the keywords
and description <META> tags.
- If you strongly believe that your
site was not ranked as high as you thought it deserved in a search query,
HotBot allows you to send them an email to bugs@hotbot.com. Be sure to
include the URL of the search page.
InfoSeek
- InfoSeek supports both the
keywords and description <META> tags. Your description can include up
to 200 characters of text and the keywords can include up to 1000 characters
of text. Do not repeat versions of a keyword more than seven times. If you
do, InfoSeek will disregard the entire keyword list.
- If you do not make use of the
description <META> tag, InfoSeek's agent will simply insert the first
200 characters after the <BODY> tag as the web page description.
Hence, if your Web document does not contain <META> tags, at least try
to make your first 200 words accurately describe your Web site.
- InfoSeek also indexes the ALT
attribute in the <IMG> tag. If the majority of your home page consists
of graphics, you can describe your page with the ALT attribute.
The syntax for an <IMG> tag
code is:
<IMG SRC="/images/clinton.gif"
ALT="picture of President Clinton">
InfoSeek Ultra
InfoSeek Ultra will make use of <META> tags allowing you to control the
description that appears in a search result as well as guide its web indexing in
the selection of your site's keywords. If you do not make use of <META>
tags, Ultra will simply use the first few words it comes across as your Web site
summary.
Lycos
Lycos creates Web site titles and descriptions from the text of your Web page.
Lycos' search agent selects a portion of the site that well represents its
theme. It then displays this section as the site's description.
The keywords are also chosen via
artificial intelligence by Lycos' spider. With this in mind, do not open your
page with an image map. If you do, Lycos will not be able to take an abstract
for your document.
WebCrawler
WebCrawler relies on the statement within the <TITLE> tag to use for the
name of your page. While other search engines will derive a summary from the
<BODY> text of the document, Web Crawler will default to the URL if you
fail to include a title.
In conclusion, do not make it your
goal to appear in the top ten list of every search engine. This would not only
be a very difficult task, but would most likely end in disappointment. You are
virtually guaranteed to have varying success rates with different search engines
due to the collection of variables that play a role in every search result.
These variables include size of database, method used for determining relevancy,
policy on spamming, use of <META> tags and more. Hence, optimize your
listings by capitalizing on the indexing criteria shared by search engines. If
you have a favorite or preferred search engine that you feel strongly about
being yielded as high as possible in a search, customize your Web pages
accordingly. Just keep in mind that this might lessen your perceived relevancy
on another.

5. How long
does it take a Search Engine to list my site?
Many of the search engines take time
to list a site. The approximate time it may take a search engine to list your
site is:
1-2 weeks: Google, Altavista,
Infoseek
2-4 weeks: Excite, HotBot, Lycos, Webcrawler
6-8 weeks: Yahoo
If after the time listed in the chart
above has elapsed and you are still not finding your site listed, you should
re-submit your URL to the search engines that do not have your listing. It often
takes more than one submission to get the best results.
Search engines receive tens of
thousands of submissions every day. On days when the submission level is above
normal, a certain number of submissions can be received properly but still not
get listed. If your listing is not appearing on a certain search engine, you
should resubmit it.
For the FAQ pages of individual
search engines, please see the following links:
Google
Altavista
Excite
HotBot
Infoseek
Lycos
Webcrawler

6. Why
should I submit inside pages of my site?
When considering how many pages of
your site to promote, it is important to remember directories generally accept
one listing per company. This is usually your home or main page. Search engines
index mulTiple pages within a site, but you cannot control which pages they will
index unless you submit the individual URLs (pages).
The critical pages to submit are your
major topic pages, pages with unique content, or pages that describe a specific
product or service. For example, a sports store will have separate pages on
basketball, baseball and football which should all be submitted. Another benefit
to submitting mulTiple pages in this example is that the basketball page will
appear higher in a search for "basketball" than the sports site home
page. These pages should also include descriptive title tags and meta tags. In
order for site visitors to easily navigate your site, these major topic pages
should provide clear links to other topic pages and your home page.

7. How do I
optimize my announcement with a directory?
Since directories are hierarchical
databases organized by subject, subject category selection would logically be
the most critical aspect of linking your site to a directory. Give some thought
to which category(s) your URL should be placed as this location will ensure the
right people (those interested in your site) will be visiting your link. URL
registrations can quickly become complex process when every directory contains a
different sub-categorization scheme.
There unfortunately is no formula or
exact method for correctly placing one's site into a subject-oriented guide.
However, here are a few Tips:
- Do not assume a category (i.e.
Entertainment) means the same thing on every directory.
- Take the time to drill down within
the directory until you come to the subcategory most appropriate for your
site. If you find many organizations similar to your own listed, you're
probably in the right place.
- Do not choose a less fitting
category because it's either alphabetically desirable or doesn't contain
many other links. If it is not appropriate, there is no reason to believe
anyone clicking that category would be interested in visiting your site.
- If you cannot find an appropriate
category, do not hesitate to suggest a new one. This advice even applies to
Yahoo!! Do you think the Yahoo! staff thought of all 22,000 headings all by
themselves?
Yahoo:
Since Yahoo! is well ... Yahoo!, it
will be discussed separately from the hundreds of other directories included in
the Submit It! Service. It actually is unique from all other directories in that
you could be listed on Yahoo! without having submitted your URL. They make use
of a robot that searches for new sites at certain Internet locations (i.e.
announcement sites, etc.). Despite Yahoo!'s implementation of this search robot,
mostly all of their new additions still come via their "Add URL" form.
Your Yahoo Submission Made
Easy
For Internet users, Yahoo! is one of
the more notoriously difficult submission forms to successfully complete. In
actuality, the Yahoo! submission form is far from a mind-numbing experience. We
have outlined the necessary steps below. If you follow them, it will not only
simplify the process for you, but also enable you to gain the greatest advantage
possible through your submission.
1. Find your Yahoo category.
From Yahoo's home page, drill down and locate up to 2 Yahoo categories that best
describe your Web site. A good indicator that you have found an appropriate
sub-category is when you scroll down and see sites already listed that are
similar to your own, or, even more so, find a direct competitor! If after
searching through a number of Yahoo categories, you still are not sure where to
place your site, try searching by a keyword you would want your site to be found
under. Existing Yahoo categories will be displayed with the search results.
Tip: Yahoo requires
commercial sites to be placed within a Business and Economy subcategory - either
under Companies or Products and Services. Personal Home pages must go in the
Entertainment/People category. If your site is regionally specific, add it to
the appropriate subcategory under the Regional heading category.
Tip: If suggesting
more than one category, press the ADD URL icon when on the category of your
first choice. Then enter the string of the second category into the Additional
Categories field. To avoid making a typo to a long string, copy the URL located
within the Address or Location field of your browser. To do this, highlight the
text after http://www.yahoo.com/ with your mousse. Right mousse click and
release the mouse over 'copy'.
For example:
Business_and_Economy/Companies/Music/
CDs__Records__and_Tapes/Online_Shopping/
2. Click the Suggest A Site
hyperlink at the bottom of the screen.
After finding the category you wish your site to be placed within, click the
Suggest A Site hyperlink at the bottom of the screen. This will take you to the
Yahoo submission form with the Category fields already pre-filled.
3. Fill out the ADD URL Form
Two particularly important fields are the Title and Description fields. Yahoo
does not allow you to suggest keywords in their submission form. Instead, it
will use both the Title and Description fields to derive search words for your
site. Therefore, think carefully about what keywords you want Yahoo to list you
under and construct your Title and Description fields around them. Do not,
however, just submit keywords separated by commas. Enter complete, coherent
phrases/sentences.
Example of a poorly constructed
title:
Brian's Music Store
Example of an optimized title:
Brian's Music Store, CD's for sale
Tip: Your title
should not exceed 50 characters (including spacing).
Example of a poorly constructed
Description:
Click to this page to listen to a wide variety of music sure to fit your
interest.
Example of an optimized Description:
Pop, Rock, New Age and Alternative CD's. Many artists, your favorite music, CD's
on sale.
Tip: Your
description should not exceed 20 words or 200 characters (including spacing).
Yahoo has employees visit the URL of
submissions to verify that the category you selected is appropriate and that the
title and description are accurate. As a result, do not exaggerate what is
located on your site. In the end, your site will simply not get listed.
4. Click the Submit button.
Once you have completed the form, click the Submit button to send your Web site
information to Yahoo. If the form has been filled out properly, Yahoo will
display a screen that thanks you for the submission. If there is an error in the
submission form, Yahoo will display a screen informing you that the submission
has failed and, depending on the error, tells you why the submission failed. In
the case of a failure, press the Back key on your browser, make the necessary
changes and resubmit.
5. Check your listing
Yahoo states that it should take two weeks for your site to be listed. They
recommend you do a search for your URL. If your site is not listed, then
resubmit your entry using the Add URL function in Yahoo. For more information,
check out Where's My
Site on Yahoo.

8. When
will I need to inform search engines and directories of updates to my Web pages?
Here are some general rules and
indicators for knowing when you need to make updates to your listings. For more
detailed information on the process involved in making updates to each
directory, consult the Submission Hints and Tips accessible within the Submit
It! Gold and Pro versions.
For search engines: Make
updates to listing:
- If your URL changes, you will need
to resubmit. Some search engines have Dead Link forms for you to fill out.
Those that do not will drop the old URL from its records the next time it
tries to visit your site at the old address and is unable to find it.
- If the content of your site
changes so extensively that the abstract no longer adequately describes your
site. These changes, however, will be taken into account when the indexing
agent next visits your site to refresh its information. Resubmitting will
hasten this process.
For directories: Make updates to listing:
- If your Web site address (URL),
description, or category classification changes, you will need to inform the
webmaster of that directory.
- If your category classification
has changed and you are now inaccurately located within the directory's
index.
Do not make updates to listing:
- If there has been minor changes
made within the site which do not alter the site's description. If the
content or purpose of the site remains the same, you are not misleading
anyone who chooses to visit your site based on the original description.

9. "Non-Netiquette"
Things
There are several "tricky"
things you can do to try to get your URL listed higher or more times on a search
engine results page. We are listing these alternatives, but are in no way
recommending them as these Web site promotion methods may be viewed as
"cheating" by some members of the Internet community. In fact, some of
the search engines are starting to penalize people that use these tricks. The
reason why we list these tricks is to help you understand why some sites always
show up mulTiple times or always at the top.
- Placing mass amounts of hidden
keywords <!software manufacturer, software manufacturer,...> at the
bottom of your document. Search engines calculate keywords by how many times
they appear on a page. It is important to be aware that search engines may
penalize you for excessively repeating keywords. At present, InfoSeek and
Lycos are two examples and others may adopt similar policies in the future.
- Changing your name to A1
Enterprises or !Rob's Restaurant in order to appear at the top. Our
suggestion is that you pick something descriptive instead. You might appear
at the top by changing your name, but be skipped over because the new one
does not evoke a professional or trustworthy company image.
- Changing your <TITLE>
regularly so when robots revisit your site to refresh their information,
they will interpret the new title to mean the existence of a new site. The
result being your page will be listed more than once in a search.
