How to Do Keyword Research for SEO?

In this post, we’ll define how to do keyword research for SEO? Keyword research is the process of finding and analyzing search terms that people enter into search engines to use that data for a specific purpose, often for search Engine optimization (SEO) or general marketing. Keyword research can uncover queries to target, the popularity of these queries, their ranking difficulty, and more.

What are keywords for SEO

Keywords for SEO are the words or phrases used in your web Content that help people find your Website via search engines like Google. Optimizing your Website with SEO keywords (according to SEO best practices) can help you bring more users and traffic to your site.

  1. Short tail keywords

Short tail keywords are made up of only one or two words.

For example, “dog” is a short-tailed keyword in the right graph.

These keywords tend to have extremely high search volume, meaning that many people search for them monthly. This may sound good if you’re trying to select keywords for your site. After all, you want to get your business in front of as many people as possible.

Unfortunately, short tail keywords also have very high competition, meaning it will be difficult to rank well for them. This is especially true if you’re starting a Website that competes against companies that have been optimizing their sites for years.

That’s why short-tail keywords aren’t preferred for SEO, at least for businesses starting to optimize their websites. A Company that’s been using SEO for years, in comparison, may target short-tail keywords without hesitation.

  1. Long-tail keywords

On the other hand, long-tail keywords can range from three to 10 individual words, sometimes even more. In the same example, “best breed of guard dog for families with children” is a long-tail keyword.

These keywords tend to have lower search volume but also much less competition. This means that even though fewer people search for them every month, you have a much better chance of reaching those people.

Plus, long-tail keywords tend to have a much clearer intent than short-tail keywords.

For example, if you were trying to rank for the term “dog,” it would be nearly impossible to know what your visitors were looking for and provide that information.

But if you wanted to attract visitors searching “best breed of guard dog for families with children,” you’d know exactly what to cover on that page.

  1. Get suggestions from the source

Get suggestions from the source

Google has more data on search activity than anyone. Have you ever noticed that as you type a phrase into the Google search field, it begins guessing what you’re looking for?

The system anticipates your needs based on the popularity of past searches and attempts to save you time by offering suggestions. Aptly, this is called “Google Suggest.” is Google Suggest on steroids. The tool helps you discover thousands of long-tail keywords related to any topic by automatically scraping every phrase from Google Suggest.

  1. Use Google AdWords Keyword Planner

The Google AdWords Keyword Planner tool was created to serve the needs of companies using their popular pay-per-click ad program. However, you can create an account whether or not you plan to pay for search ads.

The data offered via the tool is vast. Most importantly, it will serve your blog planning needs by delivering (1) approximations of the search volume for the keywords you enter and (2) related keywords. Enter an idea or several, and the tool will return up to 800 suggestions pulled from Google’s massive database.

  1. Dig into related searches

We covered the suggestions Google offers as you type. Their tips don’t stop there. At the bottom of your SERP, you’ll find “searches related to” (whatever you entered).

You might use these related phrases in a variety of ways:

  • Select one as your focus keyword.
  • Use one or more of the phrases in your post for semantic search purposes (more to come on this).
  • Take a related search and start your keyword research over again.
  1. Question shopping

Whether or not users pose their search as a question or use a question mark, the most successful business bloggers think of every search as a question.

The articles they compose present the answer. This post is an excellent example. I wrote it because I know you’d like to see the answer to:

  • com—Another free Service, in beta, gathers questions being asked across the web on forums, e-commerce sites, Quora, Reddit, and many more. The questions are intelligently grouped by topic to show which keywords and topics are used the most.
  1. Hack reviews

Continuing on our theme of Website hacking and mining the human mind, I recommend you examine reviews of books, courses, and products for additional ideas.

The study above, about a book on the art of making records, is loaded with potential keyword ideas, including some you’re unlikely to find elsewhere.

Approximating by 100s or 1000s doesn’t do it for you? Money will buy you more accurate search volume data.

Blogger Britney Muller compares the free and paid options in-depth here. And here’s an animated look at how she begins her research with the Moz tool.



In Digital Marketing, we talk about the density of Keywords or keywords to the frequency with which a keyword appears within Content; that is, it is the ratio between the times that word appears in a text and the total number of words in the text.

Keyword Density= (Number of times the keyword appears/total number of words in the text) x 100

The Density of keywords in SEO

Traditionally, keyword density was one of the most important factors when positioning organically in search engines such as Google, Yahoo, or Bing.

However, over the years, the algorithms of search engines have changed, which now reward more writing naturally. When a keyword is used excessively in a text, it is called “Keyword Stuffing,” an act that is penalized by search engines.

In this way, there is currently some debate about the ideal percentage a keyword should have in a text to position properly. There is no specific percentage.

It is recommended between 2% and 3% maximum, although the important thing is that the text is written correctly and in the most natural way possible.

If we include our keyword optimally, we are helping search engines understand the theme of our Content, and we can position better, provided that we also meet other requirements that are certainly more important for SEO, such as a low bounce rate, good link building and a considerable amount of traffic on our Website.

How to calculate keyword Density?

There are numerous programs and websites with which we can calculate the density of a word, among which stand out:

  • Word
  • Submit Express
  • Seo quake
  • PDF
  • Yoast SEO
