What is the meaning of keyword?
The meaning of keyword: A keyword is a search engine optimization identifier or word that describes the main content of a file. It is often used as a metadata to convey the meaning of text documents, images, and web pages, in order to help search engines to have clear understanding of them.
Relevant keywords may be used to tag text documents or images, to make them easier to find when searched for at a later time using those keywords. A typical example is a scenario whereby an artist tags his/her numerous artworks using keywords like “exotic”, waterfalls, “caves”, “mountains”, etc. Anytime the artist searches for a keyword like “caves”, all the artworks in that category will be instantly displayed for him/her.
On the Internet, keywords are used for identifying web page content and also as search terms.
Using keywords to describe and identify web page content:
Meta Keywords is a tag that is often used by website designers and webmasters to describe web page content. This tag placed within the header section of an HTML file usually contains almost all the most important terms on a page. This assists search engine crawlers to identify the main words the page targets. However, in recent years some search engines, especially Google, entirely ignore the Meta keyword tag, because numerous search engine optimizers have abused it with keyword stuffing.
Using keywords to find content:
Keywords are inputted into search forms when search engine users want to find any content. For example, when you want to look for web hosting providers, you may type “shared web hosting”, “shared hosting” or “shared web hosting service” into the search box. The keywords you search for will most likely yield relevant results. If you refine your search term further to include, say city or country where you like the hosting company to operate from, you can type in “shared web hosting new york, for example. The latter search term will show only hosting providers that are based in New York.
Modern well-programmed web and site search tools have support for Boolean operators, which are utilized in conjunction with keywords for enhanced search refinement. For example, the word “blackberry” both means an edible fruit that grows on the Rubus tree and also a smartphone developed by a Canadian company called Research In Motion (RIM). Boolean operators are used to pin down the exact type of blackberry you’re searching for. For example, if you’re specifically searching for a BlackBerry smartphone, an example of Boolean operators is “blackberry AND smartphone NOT fruit”.
