Step-by-step explanation:
The different types of keywords are:
Head terms
Body keywords
Long-tail keywords
Head terms are short, general keywords that describe the main topic. Body keywords are more specific and focus on subtopics within the main topic.
Long-tail keywords are highly specific and targeted, often used as phrases rather than single words.
For example, if you were researching about fall foliage, a head term could be 'autumn colors,' a body keyword could be 'effects of water and temperature on foliage,' and a long-tail keyword could be 'how does rainfall affect the colors of fall foliage?'
