Keywords have different meanings in computer programming and Internet searches. In programming, they trigger functions and cannot be used for anything else. In Internet searches, they are words or phrases used to find websites and are important for search engine optimization. Choosing the right keywords involves understanding search habits and can also affect advertising on a website.
A keyword is an important concept in computer programming and Internet protocol. It can have very different meanings depending on the context; a programming keyword is very different from a keyword used in managing search engine functions. It can be important to understand what keywords are and how they work when building a website or programming.
In terms of computer programming, keywords are used in a variety of computer languages. They are often predetermined phrases or words that trigger a particular function or behavior. Sometimes, keywords in this context are also called fallback words, meaning they cannot be used within the programming language as anything other than their intended use, such as for user-defined names or files. Some programming languages include keywords that actually have no function in the current version, but are reserved for incorporation in later versions. Examples of languages that use keywords include COBOL and C languages.
In the context of the Internet, a keyword is a very different concept. When using an Internet search tool, a user typically types a word or phrase to search. The search engine will return a list of websites that contain the word or phrase, often ranked by the number of times the word is used in the web page. The word or phrase that matches the search results is known as a keyword.
One of the most important ways websites create traffic is through the correct and complete use of keywords. People are generally much more likely to click on the first few websites that appear on a results page, so making sure a website stays near the top is critical to website popularity. The practice of building keywords or key phrases that will place a page at the top of a search engine results page is known as search engine optimization or SEO.
Choosing the right keywords for a website involves understanding the search habits of the general public. When building a website on a certain topic, it’s important to consider how people would search for information on the topic. There are programs online that can perform statistical analysis on how often a term is searched, but much of choosing keywords is common sense. Shorter terms are generally better than longer ones, while common phrases can be more common than specific terms. For example, on a website dedicated to selling cheese, a simple keyword like cheese will be searched for more often, and therefore might be a better keyword, than something like cheese making, where can I buy cheese, or Jarlsberg.
On the Internet, keywords can also be used to define advertising for a web page or website. Many advertising programs link the ads they display to keywords on a website. For example, a website where the keywords are all related to cats would likely contain advertisements related to cats, cat food, animal shelters or boarding houses. For this reason, beware of terms that have double or alternate meanings; a cybersecurity website that uses spam as its primary keyword may end up with advertisements for corned beef and canned meat, instead of antivirus programs.
