When trying to decide how to maximise the visibility of your site, it helps
to have an appreciation of how people search for information using Search
Engines.
When searching :-
Try to use words that are unusual, but relevant ("books"
will return millions of hits on virtually every subject imaginable; "manuscripts"
may enable you to track down that rare first edition you have been looking
for)
Be specific where possible (search for "book reviews of Lord
of the Rings", not "book reviews")
Use "Search within these results" options where available
(Google etc), and start with a general search, moving to more specific searches
(Search for "books", then search within for "reviews")
Learn to use quotation marks to search for phrases. If you are looking
for information on apple pie recipes, you will find different results by entering
the phrase different ways. If you use quotation marks ("apple pie recipes"),
only results where the exact phrase is matched will be returned. Without quotation
marks (apple pie recipes), any document that contains some or all of the words
in the phrase may be returned
Use of Boolean operators
When searching for specific topics, you can force inclusion or exclusion
of certain topics.
Boolean operators
The commands you need are :-
AND or +
AND/(+) - You can use the AND or the + command in identical ways, depending
on which you are most comfortable with. Each tells the Search Engine that
the results MUST contain the word or phrase after the command,
ie AND book AND review :- this searches for results that contain the word
"book" and the word "review". The search +book +review
will return the same list (note the space between the AND command and the
search term, but no space between + and the search term; + book tells the
Search Engine to look for a result that MUST contain " " and may
contain "book")
NOT or -
NOT/(-) - Similar to AND/(+), but it tells the Search Engine that its results
MUST NOT contain the word or phrase after the command.
ie book NOT review/book -review :- this will search for all documents that
contain the word "book", and then discard all of those that contain
the word "review"
OR
OR - used with phrase searches to look for many similar variations at once.
For instance:-
It is quicker to use manchester OR sunderland OR newcastle united football
club, than to type out the name of each team in full. As another example,
if you wanted information about cars, you could search for rover OR Vauxhall
OR audi +unleaded cars. This would return information about cars from the
3 manufacturers that used unleaded fuel.
The different operators can be used with each other to construct complex
searches, but pay attention to the syntax, or you can end up with very odd
results.
Filtered Words
Searching for "filtered" words. To reduce the strain on their systems,
many Search Engines throw away some words from a search string (see Glossary).
Common words like the, of, and, it etc often are not used when searching the
database.
What if you want to search on a phrase that contains them? Using AND/(+)
as described above will compel their use, enabling you to search properly
for return +of +the Jedi.
However, DON'T enclose Boolean terms (+/-, OR etc) in quotation marks, or
they will be considered part of the search string, not an instruction. Search
for +"star trek" +the +"next generation", not "star
trek +the next generation"
Link Searches
Link:www.example.com and linkurl:www.example.com searches - some Search Engines
offer the facility to check how many times other websites link to yours, using
these commands,. This is very useful when trying to determine your "link
popularity"
Use of Search Engines - Summary
Advanced users of the Web use all of these methods to find the information
they want as quickly as possible. The majority of users know how to use single
word and multiple word searches (without quotation marks), and frequently
will use phrase searching with quotation marks. As knowledge increases, simple
use of Boolean operators appears, and experts can easily construct searches
with 5 or 6 terms and various commands to instantly find what they are looking
for. You should consider the likely skills of your target audience, and modify
your strategy to suit them.
