Head term are words that have a large volume of queries in search engines.
When it comes to SEO, every web page tries to provide profitable keywords to boost its search engine rankings. And in the case of ranking, key terms play an important role, allowing you to reach more potential customers.
Key terms often have a fairly broad, generalized meaning. An example of such a term would be the word “Yoga”. Initially, it is not clear what exactly the client is looking for: a yoga mat, or maybe a set of exercises for the back. In this sense, key terms are opposed to another term – Long Tail keywords, which, on the contrary, are designed to interest people with specific needs.
Key terms, due to their large influence on the page rank in the search engine, also bring a lot of competition among the owners of web portals. Therefore, if your business is at the stage of its development, it is worth considering not using these keywords. There will always be a giant company that has more resources for advertising and will simply crush you in the area you have chosen. This is where Long Tail Keywords come to the rescue, which is not of such great interest for large companies, so they can help small sites in their promotion.
Also, if your site is commercial, it is worth realizing that often Key Terms are not of commercial interest and are more designed to generate traffic.
