Talking about Search Engines we will start from
the base, which means how crawler-based search engines work both Google and
Yahoo. Each search engine has its own automated program called a "web
spider" or "web crawler" that crawls the web. The main purpose
of the spider is to crawl web pages, read and collect the content, and follow
the links both internal and external. The spider then deposits the information
collected into the search engine’s database called the index.
When searchers enter a query in the search box of
a search engine, the search engine’s then finds the most relevant results to
the query by matching the search query to the information in its index.
What makes or breaks a search engine is how well
it answers your question when you search anything on it. This is based on the
search engine algorithm which is basically a group of factors that the search
engine uses to find out if the page RELEVANT or NOT? The higher your page ranks
the higher your page will get displayed in the search engines result pages.
