To make easy money online you
have to get high targeted traffic to your website. This
is acheived by your knowledge of how to be ranking high
in the search engines. The basic step is to know how search
engines work.
Most searh engines have three parts:
- a crawler,
- an index,
- and a search interface
.Let's look at each part individually to get a better
understanding of them. Each part has its own role to play
in the process, with all parts working together to make
searches possiple.
1.The Crawler:
Also known as a "spider" or "bot", this part of the search
engine wanders the web, following links and picking up
information for its database. Crawlers do most of their
work at times of the day when searh engines are less busy,
but they typically visit frequently updated pages more
often. This is something to keep in mind when you are
working on your pages.
Your site's title and text(your content) are the most
important thing to a crawler. The fastest way to raise
your site's search engine ranking for specific key words
is to implementthem into your title and your content.
2.The index.
Once the crawler has collected all that text, it is then
stored and indexed. This allows people searching for key
words and phrases to get results relating to what they
were searching for - their search results. Most sites
will incorporate rating systems such as Google Page Rank
or Alexa Rankings in positioning your site. These ratings
are used attempt to ensure that sites that are important
receive more traffic than unimportant sites.
To see this in action, go to a search engine and type
in a word. You'll see some text on the page saying something
like "results 1-10 of 1,234,000". This means that the
search engine's index contains 1,234,000 pages it believes
are related to the word you typed. If you wanted to, you
could look through all these pages to find the information
you're looking for.
In order to understand rating systems more thoroughly
consider your own site. When you place links on your site
you generally do so to increase your users understanding
of the content of your site.
If every site in a particular field links to a particular
site, this site is probably very important to that field
and should, therefore, be listed highly in the lists of
search engine results. This is the basic ideology of Google
Page Ranks.
Consider again , a site that receives a great deal of
traffic, it probably has some information or service that
is very important to its users. Alexa ratings attempt
to estimate the amount of traffic that a particular site
gets and compare it to the amount of traffic that other
sites get. The closer that a site is to the most trafficed
site on the internet, the more likely it is to have important
content if it is relevant to search query.
3.The Interface.
Search engines provide a public intrface for users who
want to find information on the web. They can type the
word or phrase they're searching for, and the interface
will run an algorithm to find the pages relevant to their
search and display them.
These algorithms are an important part of the SEO(Search
Engine Optimization) business. You'll notice when the
algorithms change, the rankings of your website will change
with them. No two search engines have the same algorithms.
They all work differently, with their unique features,
and they will all respond to your website in their own
way.
The most popular search engines today include Google,
Yahoo, MSN, Alltheweb, and AskJeeves.
