Advanced Keyword Research: 5 Tips for Finding Untapped Keywords

Most people start keyword research by entering a few broad seed keywords into a popular keyword tool, then checking keyword ideas.

There’s nothing wrong with this process because it makes sense to tackle popular keywords. But it does leave some of the less obvious keywords on the table.

In this guide, you’ll learn five advanced keyword research tips for finding untapped keywords.

2. Find competitors’ low-competition topics

If your competitors are getting search traffic from Google, they’ve probably already done keyword research. This means you can piggyback off their hard work by reverse engineering the low-competition topics they rank for.

Here’s how to do that: 

  1. Enter a competitor’s domain into Site Explorer
  2. Go to the Top pages report
  3. Filter for traffic from low-difficulty keywords, say under KD 20
  4. Filter for pages with 500+ estimated monthly search visits

You’ll now see pages with at least 500 monthly visits from keywords with low KD scores.

Pages with the most traffic from low-difficulty keywords
The traffic column shows the page’s estimated traffic from keywords with low KD scores.

If you see a topic you may want to target, hit the caret next to the URL and compare the URL’s total estimated traffic with the amount of traffic it gets from low-KD terms (the number in the traffic column). 

If these two numbers are relatively close, it’s a low-competition topic. 

Low-competition topics have similar total and low-difficulty traffic

If the numbers are vastly different, as is the case for our free backlink checker, it isn’t. The page just gets some long-tail traffic from low-competition terms.

3. Find and expand on unique keyword ideas

Keyword modifiers are add-ons to base keywords. Common examples include “best,” “near me,” and the current year.

For this use case, we’re looking for modifiers that do two things:

  1. Make sense combined with popular keywords in our niche
  2. Alter the search results 

For example, if we search for “best credit cards” and “best credit cards 2022” (“2022” is the modifier), the search results are nearly identical. This is because both searchers want up-to-date recommendations. In fact, the top result for both queries is the same.

Top result for "best credit cards"
Top result for "best credit cards 2022"

But if we search for “best credit cards” and “best credit cards for bad credit” (“for bad credit” is the modifier), the results are completely different. This is what we want.

The best place to look for relevant modifiers is a competitor’s Top pages report in Site Explorer.

For example, if we do this for ketoasap.com, we see keywords like “low carb mcdonalds” and “low carb at red robin.” 

Keyword rankings related to low-carb options at fast-food restaurants for the target site

Given that people are likely also searching for low-carb options at other fast-food restaurants, we can infer a base keyword and a modifier here: 

  • Base keyword: “low carb”
  • Modifier: the fast-food restaurant itself 

Knowing this, we can use Ahrefs’ Keywords Explorer to find more similar keywords. All we need to do is enter our base keyword, go to the Matching terms report, then add other popular modifiers to the “Include” filter (using the “Any word” option).

If we hit “Apply,” we end up with dozens of low-competition topics to create content about.

4. Identify uncommon seeds

Most people do keyword research the same way. They enter a few common broad keywords into a keyword research tool, then sift through the list of ideas for keywords to target.

There’s nothing wrong with this process, but the reality is your competitors are probably doing the same thing with the same seed keywords. This leads to everyone targeting the same keywords and fierce competition.

One solution to this problem is to use less competitive seed keywords to unearth keyword ideas competitors haven’t considered.

Here’s a simple way to find uncommon seeds:

  1. Enter a popular niche website into Keywords Explorer
  2. Go to the Organic keywords report
  3. Exclude common seeds
  4. Look for words and phrases that would make good seed keywords

For example, let’s say we’re in the fitness niche. If we check the Organic keywords report for bodybuilding.com, we see lots of keywords that contain common seeds like “workouts.”

If we use the “Exclude” filter to exclude keywords containing common seeds, we can then sift through the report for less common keywords that make good seeds. 

Excluding common seed keywords in Site Explorer

Here are a few that stand out from this report:

  • tdee
  • russian twist
  • bcaas

If we use these as seed keywords in Keywords Explorer, go to the Matching terms report, and filter for low-KD keywords, we see plenty of ideas with decent search volumes that competitors probably haven’t considered.

Notice that many of these have low KD scores too. This further indicates that there’s less serious competition for these keywords.

5. Find affiliate keywords at scale

Listicles of the “best” products are affiliate site owners’ bread and butter. But these aren’t the only lucrative affiliate keywords. You can also target “product comparison” and “review” keywords. 

Examples of these may be “airpods pro vs airpods max” or “airpods pro review.” 

These keywords are great because the people searching for them are close to buying. They’ve already done their research and narrowed their choices down. And because you’ll likely be their last touchpoint before they pull the trigger, you’ll get the affiliate commission. 

Here’s a simple way to find these keywords at scale:

  1. Enter a few popular brands in your niche into Keywords Explorer
  2. Go to the Matching terms report
  3. Select the “Include” filter, click “Any word,” then type “review” and “vs”

For example, let’s say we’re in the fitness niche. If we enter popular protein powder brands into Keywords Explorer and filter for “vs” and “review” keywords, we can see what products people want to see reviews and comparisons for.

Because search intent for these keywords is clear, they’re pretty much all great candidates for an affiliate website.


If you don’t know many brands in your niche, check the brands listed on a popular e-commerce site in your niche. 

For example, if we go to the “protein” category on bodybuilding.com’s store and hit the “brands” filter, we see a list of popular brands of protein powder.

Final thoughts

Keywords that your competitors haven’t found yet are usually lower competition. Being one of the first to target them is often a much easier way to build search traffic than targeting the same competitive terms as everyone else.

It’s so rare in these times to find one man with so much wow factor and more rare to find men with similar interest and passion in their life journey as myself . Dan Elliott has been introduced to many in what is now considered as the Terror Dome , a place where many dreams are not deferred they are detoured to routes that lead to dead ends , he comes in full of optimism so infectious that he, maybe with out knowing is energizing those who have ventured where others would fear going with just the right jolt to forge on in the way of helping fallen humanity … His various fields of expertise has helped many in my region and I can only imagine the number he has effected beyond those I know … from day one I knew “ this was a man of kindred spirit “ Dan Elliott is a Gem and adds glimmer to things he touches … I’m a Witness ….and eternally grateful….L.Rashaan RichMay 21, 2022
