Whenever we go to a search engine and write down our required topic within two or three words these topic words are called Keywords. A Keyword is a word or phrase - typically a phrase of two or three words - which has been identified as one which potential customers use when they are searching the internet.
A keyword is generally a word or phrase that is a topic of significance. Searchers use keywords as a way to identify and verbalize their problem or topic in which they're looking for more information. Businesses create content around relevant topics to their business which helps them rank and is the content in which searchers find.
If we want to point out so the points are:
A word that serves as a key to a code or cipher.
A significant or descriptive word.
A word used as a reference point for finding other words or information.
However, In-text editing and database management systems, a keyword is an index entry that identifies a specific record or document. In programming, a keyword is a word that is reserved by a program because the word has a special meaning. A word used by a search engine in its search for relevant Web pages. That is if you search for “Health Tips” and the results you will get are the results based on your keyword “Health Tips”. So health tips are keyword here.
There are two different types of keywords:
1. Broad keywords and
2. long-tail keywords.
Broad keywords are short words or phrases. Long-tail keywords tend to be longer words or phrases. Keywords are important for promotion and marketing for your products and services.
