A blog is like a freshly cooked cuisine with a variety of ingredients blended to enrich the depth of the flavor and the texture. There are far too many elements that influence the Search Engine Optimization of blogs. Following up on our previous post on blog SEO, today, we will focus on the magic bullet in the SEO of blogs: the keyword and the best tool for keyword research. Before that, it is needed to know the importance of keywords in blog content.

How Significant is a Keyword?

Keywords are the search terms or the search queries used by internet users to fetch the information they are looking for in a search engine. Also called search intent, it describes the purpose of an online search done by the user. Keywords could be words or phrases that describe a query in the best possible way. In response to the query term used by the user, the search engine serves the relevant data.

What are the Different Types of Keywords?

There are many types of keywords in different categories based on the length, the purpose it is used, the target information it aims at, etc. A few of them are listed below for your information.

Based on the purpose they serve, keywords are classified as

Informational Keywords

As the name suggests, informational keywords are all about gathering information on a particular topic, which the user does not have any intent to purchase. Informational keywords were used by people long before SEO and digital marketing got introduced into the scene. For instance, how to screenshot on mac is an informational keyword.


  • These keywords are used to gather information on a product, service, or a topic.
  • Informational keyword examples include search queries with “How,” “What,” “Why,” etc.

 Navigational Keywords

For your easy understanding, when an internet user types in a company or brand name into a search engine, they use navigational keywords. The search intent leads them to a navigational search which may or may not turn out into a purchase. For instance, a navigational keyword may look like apple iPhone 13 pro max amazon


  • These keywords are used to navigate to a website or a webpage.
  • Using a navigational keyword, the user need not have a clear intent to purchase.
  • When it comes to purchasing decisions, navigational keywords are related to the “considering” stage.
  • Navigational keywords examples include search queries with phrases like “Near me,” “directions to,” “prices,” “cost of,” etc. These keywords may be used along with the product/brand/service names.

Commercial Keywords

Commercial keywords are narrowed down to keywords that the user is on the hunt for a particular product or service. He is looking for the best offer that would fulfill his expectations. Commercial keywords are the keywords used in advertising commonly used closely associated with conversion. Commercial keywords are generic in nature, and they go as best kindle to buy.


  • These keywords indicate the interest of the searcher around specific brands/products.
  • Commercial keywords are generally high-traffic keywords.
  • Commercial keywords examples include search queries with words like “Review,” “affordable,” “best,” etc.

Transactional Keywords

Once the user has finished the research on a product using all the three types of keywords listed above, transactional intent keywords may be used. These keywords indicate that the user has come to a purchase decision and searching for the best deal. An example like the apple iPhone pro max case discount may lead you to have your decision-making process.


These are the keywords used for the purchase or transactional purposes.

  • Search volume for these keywords would be low, with a higher conversion rate.
  • Transactional keywords indicate the chance of conversions.
  • Transactional keywords examples include search queries with phrases like “Buy,” “discount,” “coupon,” etc.

Having understood the types of keywords based on the purpose they serve, let us move on to another criterion of keyword classification. Based on the number of words contained or the length, keywords can be classified as follows.

Long-Tail Keywords

Long-tail keywords are lengthy phrases used by people in different search engines. Studies report that the visitors who use long-tail keywords are more focused and, in business terms, are more likely to get converted. For example, a medical record review company is a long tail keyword.


  • Long-tail keywords contain more than three words.
  • Long-tail keywords are easier to rank.
  • It would have low search volume but low organic competition.
  • The possibility of ranking long-tail keywords is high.

Short-Tail Keywords

Short-Tail Keywords are crispy short phrases that are used by the majority of internet users. However, in the SEO aspect, short-tail keywords are very hard to rank and may take time to get good rankings in the SERP. Let me share with you a short tail keyword with just two words: medical chronology.


  • Short-tail Keywords may contain one to two words.
  • They are less specific and mostly generic in nature.
  • Not being very specific, they would have a high search volume.
  • The ranking possibility of short-tail keywords with heavy competition is lesser when compared to long-tail and mid-tail keywords.

Mid-Tail Keywords

As the name suggests, mid-tail keywords are phrases of medium length. They stay in between long-tail and short-tail keywords with a decent search volume. They are neither very generic nor specific in terms of usage. Have the overview on mid-tail keywords: medical chronology services.


  • Mid-tail keywords contain two to three words in them.
  • These keywords are more specific than short-tail keywords.
  • They are less competitive and would rank easily.

Let’s have a look at some of the best keyword research tools for SEO. It’s up to you to discover the best tool for keyword research depending upon your sphere, your service, and the community you’re targeting. For your easy understanding, I am categorizing the tools for keyword research into free keyword research tools and paid keyword research tools.

Free Keyword Research Tools

High-performing keyword research tools that are free to access would be the first choice of any content creator or blogger. Let’s find what is the best free keyword research tool for SEO that may help you uncover potential keywords and improve your SEO. I would like you to comprehend that free SEO research tools for keyword research do not have to provide you with the same level of functionality and customized output as paid tools. The below-mentioned are some of the best free keyword research tools used in SEO.


Google, the 23 years old search engine, has reshaped the entire planet, being the most used web-based search engine. The market share of Google during the last year was 91.94%. Google is one of the most basic yet effective tools for keyword research in SEO. When it comes to keyword research, it’s all about reading the ordinary man’s thoughts and how he uses the internet. In this regard, we can claim that the Google keyword research tool will provide you with a plethora of keyword suggestions.


Google’s autocompleting feature is a one-of-a-kind and user-friendly feature that allows you to produce an almost infinite number of keyword suggestions. When you search for any topic in the world, Google provides you with the “People also ask” option, along with a wealth of information. That’s where you’ll get ideas on how people try to find similar content on Google.

Google Trends assists content authors in determining whether or not a keyword is popular so that they can easily rank in the SERP. The statistics of popularity or trend we get from Google trends should not be compared to the search volume of a keyword you see in other keyword research tools.


You can use Google Trends to assess the trend of a keyword over a month or the entire year. This can assist you in determining when a certain keyword will have the most significant impact on users and when the best moment is to publish your content. However, the limitation is that you may not always find data on all the search queries you investigate in Google Trends.
