Keyword
Keywords are the terms that you enter into a search box in
order to find the required content. Keywords are required when you search a
database such as an online search engine, electronic index or library. For
example, if you are researching suitable hotels for your next holiday in Hawaii,
you may use keywords such as Hawaii,
hotels, holiday, etc.
There are many types of keyword searches. Usually, search
engines support free text searches. This means that they will turn up all
documents that match the keywords which you enter into the search engine’s
keyword text box. On the other hand, there are Boolean keyword searches. This
type of keyword search is more complex. It allows you to specify rules about
which results should appear in the search results. For example, you could
exclude certain keywords.
On the Internet, webmasters often expend a significant
amount of time to analyse the keywords used in their web pages in order to
increase search engine visibility. The idea is to find relevant keywords that
make the page come up in search engines. In the past, search engines used to
heavily reliant on meta tags. Today, keywords are
picked up from any location on the page.
