Targeting the right keywords determines the success of your campaigns…


Keyword research plays an important role in developing high-performing, profitable PPC and SEO campaigns. If you’re bidding on the incorrect keywords or you aren’t using a combination of short-tail and long-tail keywords, you may be missing out on potential success. 

Whether you’re looking to further develop your content marketing or expand your list of target keywords for your PPC campaigns, utilising the right keyword research tool can create a wide range of opportunities for your business. 

We specialise in PPC management services, which has given us excellent industry insights into some of the best keyword research tools on the market. We have put together a list of our top 5 recommended keyword research tools that businesses can use to improve their existing keyword set. 

The importance of keyword research 

Before we delve into our list, businesses should understand the importance of keyword research and the impact it can have on both your PPC and content marketing campaigns.  

Nowadays, the internet is the most important channel for reaching potential customers, with a 50% penetration of the global population. There is a large amount of noise and competition online, therefore, it’s important to take steps to ensure you get in front of your target audience. 

Keywords are the blueprint of your digital marketing campaigns, helping to drive every decision you make. For example, if you’re an online clothing retailer looking to advertise your products online, you must target certain keywords in your content, and your ads, to place yourself in front of users with the intent to buy. 

If you aren’t targeting the right keywords, or you’re creating content based around things nobody is searching for, you are missing out on potential conversions. Many businesses with online websites make this mistake, which is a reason why 90.63% of pages get no traffic from Google. 

How do you do keyword research? 

Keyword research is the process of learning the language of your target audiences, and the words and phrases they use to find the products they want. You can then analyse, compare, and prioritise the best keywords for your campaigns and create more opportunities for your website. 

To begin your keyword research, you must first brainstorm “seed” keywords. Seed keywords are the foundation of the keyword research process and can be used to define your niche, as well as help you to identify your competitors. 

To identify these keywords, you can look directly at your website. If you’re selling products, you will already be on your way to developing a list of seed keywords. For example, if you’re a coffee retailer, your keywords may look like the following: 

  • Coffee 
  • Espresso 
  • Cappuccino 
  • French press 

These are simple keywords that users will type into search engines to find what they are looking for. However, it’s important to note that not all these seed keywords are worth targeting, as they may have a very competitive bid.  

Instead, you should use seed keywords in the next steps of the keyword research process. You can do this by typing in one of those seed keywords in a search engine and looking to the search suggestions for further potential keywords. This can also help you to identify more competing businesses.  

What tools do you use for keyword research? 

There is a wide range of keyword research tools available, with many of them free to use. Below, we have highlighted our top 5 recommendations:
