Low Competition Keywords List: How to Build One That Ranks

You publish an article. You wait. Three months later it's sitting on page four for a keyword that six domain-authority-80 sites own. You didn't lose because your writing was bad. You lost before you started, by picking the wrong keyword.

Building a low competition keywords list is how you stop doing that. It's not a shortcut — it's just playing on a field that isn't already owned by people with ten times your resources.

Here's how to build one that actually produces rankings, not just a spreadsheet you never use.

What "Low Competition" Actually Means

Difficulty scores in tools like Ahrefs or Semrush give you a number, but that number is a proxy, not a verdict. A keyword with difficulty 15 can still be impossible to rank for if the top results are Reddit threads with 4,000 upvotes or Wikipedia pages with 10,000 backlinks. A keyword with difficulty 35 might be wide open if the ranking pages are thin, outdated, or completely off-intent.

Low competition means you have a realistic path to page one given your current domain authority, content depth, and topical relevance. That definition changes site by site.

For most sites under DA 40, "low competition" practically means:

• Keyword difficulty under 20 (by Ahrefs or Semrush scoring)
• No more than two or three strong domain authorities in the top five results
• At least one result in the top five that is clearly weaker than what you could publish

Step 1: Generate Raw Candidates

Start with more keywords than you think you need. You'll filter most of them out.

Sources that actually work:

Google Search Console — Filter your existing queries to those ranking positions 11–25. These are keywords you're already somewhat relevant for but haven't broken page one. A focused article can often push these over.

"People Also Ask" and autocomplete — Type a seed keyword into Google. The autocomplete suggestions and PAA boxes surface real language people use. These tend to be longer, more specific, and less contested. What are long tail keywords explains why specificity reduces competition structurally.

Competitor gap analysis — Find sites that are one tier above you in authority but in the same niche. Run their URLs through a keyword gap tool and pull keywords they rank for that you don't. These are proven keywords — someone is already getting traffic from them.

Answer communities — Quora, Reddit, and niche forums show you questions people have that aren't well-answered by existing content. Search your topic on Reddit and look for threads with high engagement and low-quality linked resources.

Keyword tools on low-volume filters — In Ahrefs, set volume between 100–1,000 and difficulty under 20. In Semrush, use the same logic under "Keyword Magic Tool." Don't ignore the low-volume results — low-hanging fruit keywords at 150 searches/month add up fast when you publish fifty of them.

Step 2: Filter to What You Can Win

Raw candidates need a filter. Here's the process to apply to each keyword.

Check the actual SERP, not just the score. Google the keyword. Look at the top five results. Ask:

• Are these pages from sites significantly stronger than mine?
• Are the pages actually focused on this keyword, or is it tangential?
• Is the content current, thorough, and well-matched to what the searcher wants?

If you see thin pages, old dates, or off-intent content ranking, that's your opening.

Check search intent. A keyword might have low difficulty because it's ambiguous. If the top results are a mix of product pages, forum threads, and how-to articles, Google hasn't settled on what this search means. That ambiguity makes it harder to rank, not easier. Stick to keywords where the top results are consistently the same format — all informational, or all commercial.

Check topical relevance. If you've never published anything adjacent to this keyword, you're starting from zero trust in that topic area. Google's understanding of what your site covers matters. Prioritize keywords that extend topics you've already built content around.

Remove anything with a featured snippet you can't realistically capture. If position zero is a government site or a publication with 50x your authority, you may rank on page one eventually, but you won't capture meaningful traffic without owning that snippet.

Step 3: Cluster Before You Build

Don't treat every keyword as a standalone article. Group related keywords together.

A cluster is a hub page (broad, authoritative) supported by spoke pages (specific, detailed). If your list includes "email marketing for nonprofits," "nonprofit email subject lines," and "email automation for nonprofits," those belong in a cluster — not three separate unrelated articles.

Clustering matters for two reasons:

1. Internal linking between related pages passes authority and signals topical depth
2. Publishing a cluster of related content is how you build the topical authority that makes future rankings easier

If you're targeting niche keywords your competitors are missing, clusters let you own an entire topic space rather than winning one keyword at a time.

Step 4: Prioritize Your List

You probably have 50–200 candidates at this point. You can't publish them all next week. Here's a simple prioritization framework:

Score each keyword on three factors (1–3 each):

• Traffic potential: How much could this realistically send you if you hit page one?
• Relevance: How directly does this connect to what you sell or offer?
• Confidence: How sure are you that you can rank given the competition?

High scores on all three go first. Keywords you scored high on relevance and confidence but low on volume are still worth publishing — they often convert better than high-volume terms because the searcher is more specific. This is the core argument behind long tail searches: volume per keyword is lower, but the cumulative effect of capturing many specific queries is significant.

Step 5: Build Content That Deserves to Rank

A low competition keyword gets you to the starting line. The content still has to be worth ranking.

For informational keywords, that means:

• Answering the question completely enough that the reader doesn't need to go back to Google
• Covering subtopics and follow-up questions the top results miss
• Using structure (headers, short paragraphs, clear progression) that matches how people scan search results

For commercial keywords, it means having a page that matches buying intent — not just a blog post where a product page should be.

Depth matters here. Long-form content isn't about word count — it's about completeness. A 600-word article that fully resolves the search will outperform a 2,000-word article that pads around the answer.

Scaling This Process

Once you've done this manually a few times, you understand what you're looking for. The bottleneck becomes bandwidth — finding keywords, evaluating SERPs, clustering, writing, publishing.

At scale, the biggest efficiency gain comes from competitor analysis done in bulk rather than one keyword at a time. Services like Rankfill identify every keyword your competitors are ranking for that your site isn't, map the full opportunity, and produce publish-ready content — which gives you a way to see what full deployment actually looks like before committing to it.

But the manual process described here works. It just takes longer. Either way, the underlying logic is the same: find keywords where the existing content doesn't deserve to rank, publish something better, and build topical clusters that compound over time.

FAQ

How many keywords should be on my list? Enough to keep you publishing consistently for three to six months. For most sites, that's 50–150 clustered into 8–15 topic areas. Bigger isn't better — a focused list you actually execute beats a sprawling one you don't.

What's a good monthly search volume to target? There's no universal floor. Keywords with 100–500 searches/month are often worth targeting if difficulty is low and intent is clear. At scale, many low-volume keywords add up to significant traffic. Don't filter out anything under 1,000 automatically.

How long before I see rankings? For low-competition keywords on an established domain, often 4–10 weeks. On a newer site with lower authority, expect 3–6 months even for easy terms. Google needs to crawl, index, and test your page before it stabilizes in rankings.

Should I update my list regularly? Yes. Run this process quarterly. Competitors enter and exit topics, your domain authority changes, and new keyword opportunities emerge constantly. Treat your list as a living document, not a one-time output.

Does this work for e-commerce product pages or just blog content? Both. For e-commerce, low-competition keywords often appear in product category modifiers ("wide fit walking shoes women") or buying guides. The SERP analysis and clustering principles apply exactly the same way.

What if my whole niche is high competition? Go narrower. High competition at the category level almost always has pockets of low competition one or two levels deeper. A keyword like "project management software" is brutal. "Project management software for architecture firms" probably isn't. That's the move.
