The 5 Best Long-tail Keyword Generator Tools

Long-tail keywords are nothing more than keywords with low monthly search volumes. It doesn’t matter if they’re made up of two, three, or 10 words.

Thanks to their low popularity, they’re often less competitive and easier to rank for than short-tail keywords. This makes them an excellent target for new websites.

In this guide, you’ll learn how to find long-tail keywords using five main tools.


There are two types of long-tail keywords, and it only makes sense to target one of them. We’ll focus on finding that type below. If you’re curious about the differences between the two types, read

2. Ahrefs’ Site Explorer

Site Explorer is a competitive research tool. One of its main features is to show the keywords your competitors rank for. 

Here’s how to use it to find your competitor’s long-tail keywords:

  1. Enter a competitor’s domain
  2. Go to the Organic keywords report
  3. Filter for keywords that rank in positions 1–10
  4. Filter for keywords with a monthly search volume up to 300

As there is currently no Traffic Potential (TP) filter in Site Explorer, you’ll need to check the traffic potential of these long-tails manually to decide if they’re worthwhile targets. To do this, install Ahrefs’ SEO Toolbar, then check the traffic to the top-ranking page in Google.

Make sure “SERP tools” is active on the toolbar. To do this, click the orange “a” logo in your browser and toggle the switch on. 

If the top-ranking page gets more than a few hundred monthly search visits, it’s probably not the best keyword to target, as ranking will usually be difficult.

Looking for a way to check Traffic Potential in bulk?

Export the site’s keywords from Site Explorer, then:

  1. Paste the keyword list into Keywords Explorer
  2. Filter for keywords with a Traffic Potential (TP) up to 300

The long-tail keywords tools and processes below are completely free. However, the results aren’t as good, and it takes a bit more effort to get there.

3. Google Keyword Planner

Google Keyword Planner is free to use. It’s made for advertisers, but you can still use it to find long-tail keywords. To do that, click “discover new keywords,” then:

  1. Enter a broad topic as a seed keyword.
  2. Sort the results by average monthly searches from low to high.

Keywords with a monthly search volume range of 10 to 100 or less are long-tails. But they may not be the best targets if they’re just uncommon ways to search for popular topics. 

To check, search for the keyword in Google and plug the top-ranking page into Ahrefs’ free traffic checker tool. Generally speaking, you want to see no more than a few hundred monthly search visits to the page.

4. Google autosuggest

Although long-tail keywords can have any number of words, our study found that wordier keywords are more likely to be long-tails. This is what makes Google autocomplete a good source of long-tail keyword ideas.

Here’s how to use Google autocomplete to find keywords that are long-tails: 

  1. Search for a simple topic on Google
  2. Cycle through autocomplete results until you find a long keyword
  3. Check traffic to the top-ranking page with Ahrefs’ free traffic checker

For example, if we start with “hairstyles,” we can easily get to “korean hairstyle for girl long hair” in seconds just by scrolling through the suggested searches.

But we then need to check that this isn’t just an unpopular way of searching for a popular topic. To do that, we can plug the top-ranking page for this query into Ahrefs’ free traffic checker.

If it gets a few hundred visits or fewer, it’s what we’re looking for. If it gets thousands of visits, it’ll probably be hard to rank for.

In this case, it only gets an estimated 106 monthly search visits, which is what we want.

Reddit is another good source of potential long-tail keywords. But once again, you’ll have to check traffic to the top-ranking page for any ideas you find to make sure they’re what you’re looking for.

For example, here are a couple of hyper-specific topics I came across on the SEO subreddit:

Potential long-tail keyword from the /r/seo subreddit

If we plug the top-ranking page for “how to improve off page seo” into Ahrefs’ free traffic checker, we see that it gets thousands of monthly search visits.

This means the keyword isn’t the kind of long-tail we’re looking for. It either has a high search volume in itself or is an uncommon way to search for a popular topic. Either way, it’s probably hard to rank for.

On the other hand, the top-ranking page for “seo for news website” gets under a few hundred monthly search visits.

This means the keyword must be long-tail, and it isn’t an unpopular way of searching for a popular topic. That’s what we want.

Final thoughts

Just because a keyword is a long-tail one doesn’t necessarily mean it’s easy to rank for. There are plenty of examples of high-competition, long-tail keywords. 

For example, “vpn for beginners” only gets an estimated 40 monthly searches in the U.S., but it has a hard Keyword Difficulty (KD) score of 50/100. This is because VPN affiliate commissions are high, so the keyword still has high competition.

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

We'd used some other agencies before, but man, they simply knocked us all over. After being in business for 30 years, I wonder how much more business we'd be doing if we'd hired them earlier.Rebecca HoneaMay 17, 2019
