Short Tail keywords
For example: the keyword «instagram followers». It has over 11 493 search requests per day so the competition for it is very high. If you wish to target that keyword in your content, you're not going to rank highly for it for a very long time. You need to add it to your description and create a keyword promotion strategy to get into its rank. For example, first to target long tail keywords like 'instagram followers for free' and gradually move to shorter keywords.
