Whether you’re a seasoned SEO Consultant or a total beginner in the space, it’s important to understand that the goal of keyword research is to generate a large number of highly relevant terms for your business. Put simply, these are all the possible Google search terms that someone could use to ultimately find your business.

To get the best results, it is important to optimize your website and backlinks to cater for the most relevant keywords - and that doesn’t mean just the obvious ones. It is good practice to look for niche keywords where competition is low and demand is high. This makes it easier to achieve higher rankings in search engines, which generally is a surefire way to increase traffic to your site.

What are keywords?

Keywords are a word or phrase that describes your content. In terms of blogs and SEO, you can think of keywords as the key between what people are looking for — their search queries — and what you offer.

Organizing keywords

Short tail vs long tail keywords

Source: BigCommerce.

There are three types of keywords:

  1. Short tail, also known as Head. These usually consist of one or two words, for example, “red automobile”. These words are broad and generic, and often vague keywords.
  2. Medium tail, also known as the Body. These keywords usually consist of three or four words; for example, “racing red automobile”. They are more specific and descriptive.
  3. Long tail. Long tail keywords usually consist of four or more words; for example, “german racing red automobile”. These are detailed and very specific, which means that search volume for these keywords is generally lower than short or medium tail keywords. The term “long tail” comes from the so-called “search demand curve”.

Organization by intent

The first step is to organize keywords by intent:

  • Navigational (Go): A browsing search query is often called a “go” query because it is used when people want to find a specific website or page.
  • Informational (Know): An informative search query is about researching people's issues and looking for answers. Therefore, it is also called 'know' query.
  • Transactional (Do): Use transactional search queries when users are ready to make purchase decisions or for lead generation. These queries are called “do” because the action is coming.

Organization by content type

Depending on your site, different keywords can become different forms of content:

  • Frequently Asked Questions Page
  • Blog articles
  • In-depth articles (perhaps available for download in pdf)
  • Live Glossary
  • Product Reviews
  • Various types of content of cornerstone
  • LSI (related searches) and synonyms

About LSI keywords
This represents potential semantic indexes. They are words that are usually found in a single topic and are semantically related to each other. They have to tell the search engine what their content is, because the same keywords can have multiple meanings.  

Best Keyword Research Tools

1. Google Ads Keyword Planner

Google offers a suite of free tools that are helpful for conducting basic keyword analysis. All results are based on data from Google’s ads engine.

Google recently released an update to Google Keyword Planner which now requires you to set up a proper campaign in order to retrieve data.

Key features:

  • Displays search volume estimates for keywords.
  • Generates new keyword suggestions by combining keyword lists.
  • Creates new keyword variations based on the primary keyword.

Restrictions:

  • Hides long tail keyword data because the tool was created for Google Ads, not for SEO purposes.
  • The keywords generated by the device may not produce good results because the tool is targeted at advertisers rather than SEO.
  • Google started limiting output options for advertisers (or accounts) with low or zero monthly spending.

2. Bing Ads Keyword Planner

Bing’s Ads Keyword Planner provides ad group suggestions and displays monthly average trends, relative competition, and suggested bids.

Key features:

  • Displays search volume data and trends.
  • Generates estimates of performance and costs.
  • Multiply keyword lists to new keywords.

Restrictions:

Bing represents only 20% of the search engine market in the United States and provides data that may not be as useful or reliable, at least for websites optimized for Google Ads engines. Also, like Google Ads Keyword Planner, the tool provides data to help advertisers and not publishers.

  • Alphabetical – a, b, c, etc.

Google Suggest is often used as a real-time function when a user enters a search phrase in a browser or Google website.

This makes Google Suggest a relevant source of keyword research. You can find a large number of organic keywords that are very closely related to the live searched keyword. This is an “automatic suggestion” feature that generates an almost unlimited number of keyword ideas.

For beginners, pay attention to the box “People ask too” that shows some searches. You can generate an almost infinite list of questions asked by people.

There are many factors at work when it comes to SEO, but one thing is certain: if you want to rank in 2019, then you need to align your content to search intent.
