Keywords help with organic discovery. They are essential to get picked up by the search engine algorithms. But beyond that, keywords will help you build your content and marketing campaigns.

A keyword gives you insight into what users are looking for. Knowing this may drive your content in one direction, or the other. You should not solely base your content around the use of keywords. You still need to create original, and natural-sounding work. But without paying attention to some keywords, it is difficult to almost impossible to stay competitive.

The same principles apply to your marketing strategies. Researching keywords will help you understand analytics better. They give you context around the behavior of the audience. Showing you what is on their minds, and what kind of marketing they will resonate with. Also, there are different types of keywords. Understanding when to focus on certain words will make you more effective at marketing.

It can also give you an idea of why your competitors are succeeding. If they rank well, looking at their keywords can help identify blind spots in your strategy. Use this to your advantage, and implement competitive keywords to gain an edge.

Important Types of Keywords:

The basic keywords can be divided into two separate categories. First, are the primary keywords. These are focused on what your content is all about. With these keywords alone, you should be able to get almost all of the context you need to know what your content is about. Common primary keywords will be the location of your business, type of service, or subject matter. It is the things someone will immediately type to find your content.

On the other hand, secondary keywords are related but more specific in nature. They will be similar enough that most of your content can be supplemented by secondary keywords. But you will not have to create content around them. Examples can be phrases that refer to time or specific actions that might be involved in your content or service.

Next, we have a new kind of keyword related to voice search. These are called long-tail keywords and are becoming more popular. They are more like key phrases than words. Long-tail keywords work well because they capture the more natural vocabulary used in voice searches. The phrase will usually be a very specific question, looking for a very specific answer. The number of searches targeting long-tail keywords is growing, so don’t overlook these. If you are a local business, make good use of them.

Finally, we have semantic keywords. These keywords come into play because of the latent semantic indexing technology used by search engines. What this means is that Google is getting better at understanding implied or context-specific meaning. When you make a search, Google will try to identify synonyms or similar phrases to help guide you to what you need.

By including these semantic keywords, you help search engines figure out the context of your content. It will be easier for Google to thus put under certain categories, and provide better (and more) recommendations to users. This plays into voice search as well. Try to imagine how you ask someone a question. Doing this will help you see what kind of semantic keywords you should consider.
