Keywords are words and phrase, people types in the search box to find the products and services. You have to know which keywords are searching for people to finding your products and services. By doing keyword optimization (or) keyword research to make a list of all keywords then choose primary, secondary and tertiary keywords.

When you are creating a new website or writing an article, keywords will play the main role in the SEO part. Primary, secondary and tertiary keywords will help direct traffic from Search engine to your website.

All are using only primary keyword when setting up SEO, but they did not focus on the secondary and tertiary keywords. Understand their purpose and use the right way both secondary and LSI keywords and get traffic to your website from the right audience.

Primary Keyword:

A primary keyword is the name of your web page or an article. That keyword is used always first then other keywords on a webpage or an article.

The primary keyword must and should be added to your web page title, URL and description. And the primary keyword should be added in the first paragraph on the webpage or an article.

The primary keyword is a part of SEO and it will decide, what is overall content is about. Don’t select simply any keyword. Before selecting check-in that keyword has a volume and competition is there are not. If you choose the keyword which has no volume and no competition, it will not help your business and simply you’re wasting your time.

The primary keyword is very important on your webpage.

By using Google trends, you can check how much search volume is there for keywords. Notice that "digital marketing course", "online marketing course", and "internet marketing course" every keyword search volume is different.

You can’t pick like what keyword in your mind. You need to check which keyword volume is low (or) medium (or) high and choose the best keyword for your services.


When your competitors are choosing their primary keywords by gut feeling, their option probably not be great. It’s just high expansive for you and a lot of companies are fighting for "digital marketing course" keyword.

If you go for PPC also you have to bid a high cost per click for that. Even if you bid high also you don’t know the conversion is there or not.

Your competitors are working only on "digital marketing course" keyword because the competition is high for that keyword. If you choose "Digital marketing course" might be a long-term goal for you to get rank on the first page.

Your competitors are not working on a "digital marketing training" keyword. You can use that information and work on digital marketing training keyword. Definitely, you will get rank in the next three months. Once you get the first rank for that keyword, then automatically you will get more traffic from your competitors.

Secondary Keyword:

Secondary keyword is using after the use of a primary keyword. The secondary keyword helps to the supporting role of primary keyword.

If you target only primary keywords, It has high search volume, but definitely, it will take time to get good rank in search results.

That’s why on the other hands, you have to target the secondary keywords also that will help to get rank quickly.

If anybody is starting to the new website, alternatively you should target the secondary keywords also. Because all are targeting only the primary keywords, they are not targeting the secondary keywords. If you target both primary and secondary keywords at a time when you are writing an article, then it’s easy to get rank quickly. This is the main advantage of secondary keywords.

LSI (Latent Semantic Indexing) keywords are related to your primary keyword. So many peoples are thinking LSI keywords are synonyms. But that is wrong. LSI keywords are simply words that are related to the same content.


  1. If it finds the words: ‘facebook’, ‘LinkedIn’, ‘twitter’, ‘Instagram’, ‘like’, ‘follow’, ‘engagement’, your article is probably about social media.
  2. It finds the words like: ‘vehicles’, ‘hero Honda’, ‘Yamaha’, ‘Bullet’, ‘Bajaj’, ‘buy’, ‘sell’, ‘repair’, your article is probably about bikes.
