Evaluating what your competitors are doing can help you discover missed opportunities that you are not aware of. So when you do further planning and investigation, it can help drive traffic and revenue. 

This technique is literally the holy grail of finding new keywords. In this guide, we will teach you about keyword gap analysis and the best practices. With keyword gap analysis tool like RankingGap, you can reduce hours of SEO work and concentrate on other areas of your business..

What is Keyword Gap Analysis?

Keyword gap analysis identifies keywords that send traffic to your competitor’s site instead of your website. 

Keyword gap analysis helps you find out valuable keyword opportunities that you may be overlooking. Using this information, you can create a list of keywords that your competitors are targeting and tweak your strategy accordingly.

Keyword gap analysis allows you to:

  • Quickly find new keyword opportunities.
  • Determine keywords that are working for popular sites.
  • Figure out valuable and high volume keywords quickly.
  • Identify topics that your audience is interested in.

The key of competitor keyword analysis is to pick 1-2 competitor or top websites in your niche. Once you’ve picked them, keyword gap analysis tools can help you find those keywords that are driving traffic to them.

Why do you need to do keyword gap analysis?

As of 26 January 2022, Google processes over 3.5 billion searches every day, or 1.2 trillion searches per year. With this competitive reality, you cannot rank higher on the SERPS, if you cannot find the relevant keywords for your business. 

Keyword gap analysis can help you identify competitor’s content gaps. This uncovers many more content opportunities that you may have overlooked previously. It is the perfect way of ranking for the right terms related to your products and target audience. After all, it would be useless to rank for keywords your customers are not searching for. 

By evaluating your competitors, you can create a long list of keywords and terms that they are targeting, as well as other techniques and how they are using these terms to get better outcomes online. In most cases, your list of keywords will help you carry out an even more exhaustive analysis and comprehensive evaluation of what keywords are better to rank for and which are not.

Conducting a competitive analysis can pinpoint opportunity gaps between your keyword strategy and that of your competition. Plus, it can highlight areas of opportunity as well. By assessing competitor websites, you can create a list of keywords that they are targeting and determine how they are targeting those keywords.

Think of this list as a seed keyword list. You can perform a more granular analysis of the keywords to identify if you should target them. Besides short-tail keywords, keyword gap analysis can also help you find long-tail keywords. Long-tail keyword searches have a click-through rate 3% to 5% higher than generic searches.

In most cases, this opens up new avenues of ideas that otherwise have never been discovered. It is beneficial for getting actionable insights and formulating new strategies.

With a competitor keyword gap analysis tool, you can save a lot of time. RankingGap is one of the best and most beneficial tools to discover your keyword gap.

The first step: competitor keyword analysis

Before finding your keyword gaps, you need a list of domains that are competing with your domain in SERP. 

Your competitors may vary according to your business objectives, time framework, and resources. Instead of trying to outrank them all at once – which you’ll soon discover is not feasible – you should focus on one competitor at a time. 

One simple way to discover who your competitors are is by entering your seed keywords one by one into Google search and see who appears on the first page. Then, check every competitive website that ranks on the first page. However, this will not give you much data about their performance.

We suggest you use RankingGap for this first step. You can again find your competitor using the RankingGap “Discover Competitor” feature. .

Then, turn your efforts towards outranking the competitor that’s right above you in the SERP for your target keyword.
