So you want to do SEO, advertise or write a blog post for your organization. Keyword analysis is the cornerstone of any digital marketing strategy. It gives you high and low search volume keywords related to your product or service. To come up with the best plan to grow your company, a customized, long tail semantic keyword analysis is essential. The keyword research gives you an extensive list of many things. You get keywords related to your product, how often people look for it, the cost and a general oversight of search behavior related to your product. Use the keyword analysis also to find content gaps compared with the competition. The most relevant search terms from the keyword analysis are also used on the website, in meta tags, ad copy, blog and social media posts. The contents of this blog posts are:

What is a keyword or topic cluster? A simple and short explanation is below in this video:

What is the “long tail”?

Back in 2006 Chris Anderson (from Wired magazine) wrote the book “The Long Tail”. A graph summarizing the book is below.



You can also apply the long tail concept, or niche products, to businesses like Amazon. Unlike offline companies, Amazon can carry a huge amount of books that very few people are looking for in its warehouses, making it more profitable than offline bookstores.

What are “semantic” keywords?

The word “semantic” is literally about “meaning in language or logic”. In digital marketing, semantic means “related”. Semantic keywords are also called “Latent Semantic Indexing” (LSI) keywords. If you want to find related (long tail) keywords for a search term very quickly and easy, just go to Google and type your keyword (example: “drinks”). You will find some related terms at the bottom of the page:

The search volumes and CPCs on the right are from an extension Keywords Everywhere. If you want more long tail keywords, go to Google or Naver.

Google Keyword Planner

Sign into your Google Ads account and go to “Tools” and then “Keyword Planner”.

find new keywords

Click “Find new keywords”.

Type “drinks” and press “Get started”. Now you have a list of 508 related (or semantic) and long tail keywords. Long tail keywords are more than one word keywords, like “hot drink”, “alcoholic drink”, “soft drink” or “energy drink”. A short tail keyword or seed keyword is “drink”.

planner location language

You can change the location and language on the top left. You can also select cities, depending on where your target audience is.

Tick the box next to “keyword” until it’s blue and “select all 508”.

download keywords

Now click “download keyword ideas” to get all keywords in a spreadsheet. You can also change the seasonality, for example 1 month, 24 months or all available data.

Above is a screenshot of the 508 keywords in a spreadsheet. We will now categorize the keywords in ad groups or clusters. Organizing keywords in different categories can be quite time consuming.

Keyword grouper

Let’s use a free keyword grouper tool that sorts them automatically and quickly. There are a few available:

Unfortunately, the tools do not work well with languages like Korean.

keyword grouper

Here the keywords are grouped in clusters of at least 10 keywords each using marketbold. You can download the keyword groups in a spreadsheet. Below is the list of the 15 clusters with number of keywords in it in parentheses:

  • alcohol (10)
  • alcoholic drinks (44)
  • bar (18)
  • beverage (17)
  • beverages (30)
  • cocktail (23)
  • cocktail drinks (20)
  • cocktail recipes (28)
  • cocktails (12)
  • drink (72)
  • drink menu (14)
  • drink recipes (62)
  • drinks (77)
  • drinks menu (11)
  • mixed drinks (51)

Although there is no magic number, it is probably a good idea to put between 10 and 20 keywords in each ad group. Let’s organize the ad groups that have over 20 keywords in them into smaller clusters. The best way to do this is by trying to figure out the search intent. What is it that the drinker is looking for?

Search intent

There are four types of search intent:

  • Informational
    • Example: “how to make beverages”
  • Research
    • Example: “different beverages recipes”
  • Purchase
    • Example: “buy drinks”
  • Navigational
    • Example: brand names like “Honest Tea”, “New Belgium Brewing Company” or “Samuel Adams” or website addresses

search intent


Depending on the nature of the keywords, it is a good idea to sort keywords in ad groups based on either search intent or similarity. Some keywords have a higher CTR or conversion rate. Usually branded keywords or keywords with high buyer intent produce more leads or sales. Let’s take a look at the ad group “Cocktail” that has 23 keywords. We will split this group into smaller ad groups.

You may have to type the search term into Google to find the search intent. Search engines’ algorithms continually match search term with the matching results. The new smaller clusters are below.

In PPC, why is it important to split ad groups into smaller ones? This way you increase the relevancy and quality score: matching search intent, keyword with ad text and landing page. Increasing your quality score and CTR you will have a lower CPC.
