Knowing that low competition keywords exist is one thing. Knowing how to find low competition keywords consistently - without burning three hours clicking through SEO tool tabs - is a different skill entirely. Most guides tell you to “use a keyword tool and filter by KD.” That’s one method. Here are four.
Each approach surfaces a different type of opportunity. Seed expansion catches the obvious stuff. Competitor gaps find terms your rivals rank for with weak pages. Autocomplete mining pulls directly from what people actually type. And forum scraping uncovers questions that haven’t been turned into proper articles yet.
Use all four together and you’ll never run out of low-KD targets.
Method 1: Seed expansion with KD filtering
This is the bread-and-butter approach. It works, but only if you’re aggressive with filters and don’t stop at the first export.
Start with 5-10 seed keywords in your niche. If you’re in email marketing, your seeds might be “email marketing,” “newsletter tools,” “drip campaigns,” “email automation,” and “email list building.” Broad terms. Category-level stuff.
Drop those into your keyword research tool and export the full suggestion list. You’re looking at 5,000 to 30,000 terms per seed depending on how competitive the space is.
Now filter:
- KD under 25. If your site has some domain authority (DR 30+), push this to 30. If you’re brand new, keep it at 15.
- Volume above 50. Below that, the keyword still has value but probably doesn’t deserve its own page. You’ll pick those up through supporting content.
- Remove branded terms. Unless you’re writing comparison posts, filter out anything with a competitor’s name.
- Three or more words. Single and two-word terms with low KD are almost always misleading. The tool is underestimating the difficulty, or the intent is so vague that ranking won’t drive useful traffic.
A seed like “email marketing” filtered this way might surface: “email marketing for real estate agents” (KD 14, 590/mo), “how to warm up an email domain” (KD 9, 320/mo), “email marketing without a website” (KD 11, 210/mo). Those are specific, clear intent, and genuinely low competition.
Where most people stop too early: they run three seeds and call it done. Run ten. Run fifteen. Try different angles on the same topic. “Newsletter growth” surfaces different long-tails than “email subscriber” even though they’re the same space.
Method 2: Competitor gap analysis for low-KD terms
This one’s underrated. Instead of starting from scratch, you piggyback off what your competitors have already discovered - then cherry-pick the easy wins they’re ranking for with mediocre content.
Here’s the process:
Pick three to five competitors in your space. Not the giants - pick sites that are one or two steps ahead of you. Sites with DR 20-50, publishing consistently, ranking for a few hundred keywords. These are your peers, and the keywords they rank for are the ones within your reach.
Run a keyword gap analysis between your site and theirs. You want keywords where at least one competitor ranks in the top 20 but you don’t rank at all.
From that list, filter to KD under 30. Then sort by volume.
What you’ll find: a pile of terms your competitors stumbled into. Maybe they rank #14 for “content calendar for solo founders” with a thin paragraph buried in a longer post. That’s your opening. Write the definitive page for that term and you’ll outrank their accidental mention.
The real advantage here is intent validation. If a competitor already ranks for a term, Google has confirmed that your type of site can rank for it. You’re not guessing whether an informational page belongs there - someone like you already proved it does.
Check the actual SERPs for your top 20-30 candidates. Look for competitors ranking with:
- Old content (last updated 2+ years ago)
- Shallow coverage (under 600 words on a topic that deserves 1,500)
- Poor formatting (walls of text, no headers, no visuals)
- Mismatched intent (their product page ranks for an informational query)
Any of those signals means the spot is takeable.
How to Find Low Competition Keywords Through Autocomplete
Google autocomplete is a live feed of what people actually search for. It’s free, it’s real-time, and most SEOs ignore it because it doesn’t come in a spreadsheet.
The manual method:
Type your seed keyword into Google and stop. Don’t hit enter. Look at the suggestions. Now type each letter of the alphabet after your seed: “email marketing a,” “email marketing b,” “email marketing c,” and so on. Each letter triggers a different set of suggestions.
Write down every suggestion that looks like an actual question or specific topic. You’ll get 50-100 terms in about 20 minutes.
The faster method:
Use a tool like AnswerThePublic, AlsoAsked, or KeywordSurfer’s autocomplete scraper. These automate the alphabet soup approach and return structured lists. Some are free, some aren’t. Either way, they save time.
Why this works for finding low-competition terms:
Autocomplete suggestions are weighted by search volume and freshness. When Google suggests a long-tail phrase, it means people actually search for it - but these phrases often haven’t been picked up by keyword databases yet. Your keyword tool might show “no data” for a term that gets 200 searches a month. Autocomplete knows about it anyway.
Cross-reference autocomplete suggestions with your keyword tool to get volume and KD estimates. But don’t discard terms with no data. If Google autocomplete surfaces it, there’s traffic there. Write the page, index it, and check Search Console in 60 days.
Pro tip: Run autocomplete in an incognito window. Your search history skews suggestions, and you want to see what the general population gets.
Method 4: Forum and Reddit topic mining
This is where you find keywords that don’t exist in any keyword tool yet. People ask questions on Reddit, Quora, niche forums, and Facebook groups months or years before those questions show enough search volume to register in Ahrefs or SEMrush.
How to mine Reddit:
Search site:reddit.com [your topic] in Google. Look at the threads that rank. If a Reddit thread ranks on page one for a query, that’s Google saying “I don’t have anything better.” You are something better.
Go to the relevant subreddits directly. Sort by top posts for the past year. Read the questions. Look for patterns - the same type of question asked slightly differently by dozens of people.
For example, in the SEO subreddit you’ll find recurring threads like “how do I know if a keyword is too competitive for my site” or “what keywords should a new blog target first.” These map directly to high volume low competition keywords people are actively searching for - they just phrase them differently than what keyword tools index.
How to mine niche forums and communities:
Every industry has at least one forum, Slack group, Discord server, or Facebook group where practitioners ask questions. These are goldmines because the language people use in communities is the language they type into Google.
Spend 30 minutes reading recent threads. Copy every question that could be answered with a blog post. Group similar questions together - that’s your keyword cluster.
The validation step:
Take your forum-sourced topics and check Google. Search the exact question. If the results are Reddit threads, forum posts, or outdated articles, you’ve found a gap. Check your keyword research tool for volume estimates, but don’t let “no data” stop you. Forum activity is a leading indicator of search demand.
Combining all four methods
Each method has blind spots. Seed expansion misses emerging topics. Competitor analysis only finds what others already target. Autocomplete skews toward popular queries. Forum mining is labor-intensive and doesn’t come with volume data.
Run all four and you get a complete picture.
A practical workflow:
- Start with seed expansion to build your base list. Budget 45 minutes.
- Run a competitor gap analysis to catch what you missed. 30 minutes.
- Mine autocomplete for long-tail variations. 20 minutes.
- Scan forums for questions nobody’s answering well. 30 minutes.
That’s about two hours of work, and you’ll walk away with 100+ validated low-competition keyword targets. Enough to fuel three to six months of content, depending on your publishing pace.
Prioritize by combining KD and business value. A KD-8 keyword with zero relevance to your product is worse than a KD-22 keyword that maps directly to a use case your customers care about. Low competition matters, but only when paired with traffic that actually converts.
What to do after you find them
Finding keywords is the easy part. The hard part is turning a list of 100 terms into a publishing plan that builds topical authority instead of scattering random articles across your blog.
Group related keywords into clusters. “Email marketing for real estate agents,” “real estate newsletter ideas,” and “best email subject lines for realtors” all belong together. Publish them as a cluster, interlink them, and you’ll rank faster than publishing them months apart with unrelated content in between.
Track your rankings weekly for the first 90 days. Low-competition keywords should start showing movement within 30-60 days. If nothing moves after 90, the keyword isn’t as low-competition as the tool said - or your content missed the intent.
The sites that win at this aren’t the ones who find one batch of easy keywords. They’re the ones who run these four methods every quarter, build a pipeline, and publish consistently against it.
