Key Takeaways
- Brainstorming “original” content ideas is a gamble. Most guessed topics flop because nobody was searching for them in the first place.
- A keyword gap analysis shows you the exact terms your competitors rank for, and profit from, that your site is missing entirely.
- SirLinksALot’s Keyword Gap Analysis Tool surfaces high-volume, low-to-medium competition keywords: the easiest wins on the board.
- SirWritesALot’s keyword clustering can pull thousands of a competitor’s keywords and sort them into a ready-made content plan in minutes.
- Speed wins heists. AI-assisted writing lets you publish a stronger, optimized article before your competitor even notices the gap.
- Not every keyword is worth chasing. Prioritize by search intent, the volume-to-difficulty ratio, and how closely it matches what you actually sell.
Staring at a blank content calendar, trying to will an “original” blog idea into existence? Stop right there. That’s the rookie move.
Here’s the uncomfortable part: most of what gets published never earns a single visitor. Ahrefs studied roughly 14 billion pages and found that 96.55% of them get zero organic traffic from Google. Zero. Guessing what to write is, statistically, a losing bet.
Meanwhile, your competitors have already researched for you. For free. Every keyword they rank for is proof that real people are searching for it, and proof that Google already trusts a page like theirs to answer it.
Your job isn’t to invent demand out of thin air. It’s to find where competitors are quietly cashing in, then get there first with something better.
Think of this as a heist. Not the illegal kind — nothing here breaks a law or a website’s rules. Just sharp, old-fashioned competitive intelligence: recon, a target list, and a fast getaway. Here’s exactly how to analyse competitor keywords and start pulling their traffic your way.
The Recon: How to Analyse Competitor Keywords
Every heist starts with a walkthrough of the target. In SEO, that’s called a keyword gap analysis, and it’s the fastest way to build a content plan that’s already proven to work.
Here’s the idea: pick one or more competitors, then compare every keyword they rank for against your own site. The keywords they own that you don’t? That’s your gap. That’s the vault.
SirLinksALot’s Keyword Gap Analysis Tool does this automatically. Plug in your domain and a rival’s, and it lines up the keywords side by side so you can see exactly where you’re losing ground and where you’re being outranked completely.
For each keyword, you’ll see:
- Your Rank vs. Competitor Rank — who’s actually winning that search result right now
- Search Volume — how many people type that exact phrase into Google each month
- Competition Level — how hard that keyword is to rank for
- Estimated Traffic Value (ETV) — roughly what that ranking is worth in traffic
The sweet spot to look for is high search volume paired with low-to-medium competition. Those are keywords with real demand that haven’t been locked down by a dominant player yet, which makes them realistic targets even for a smaller or newer site.
Casing the Joint: Proof This Actually Works
Skeptical that analysing competitor keywords can really move the needle? Fair enough. Here’s a real one.
An SEO consultant working with a company that sells insurance to Amazon sellers ran a routine competitor keyword gap analysis. One discovery stood out: a rival was pulling almost all of its organic traffic from a single article built around one keyword cluster. She called it a “golden keyword” — one article carrying that much weight isn’t something you see every day.
Instead of copying that article, her team built something stronger: sharper technical SEO, a wider set of supporting keywords, and a more useful angle for readers. The payoff was 398 clicks and 11,000 impressions, with a clear traffic spike that started soon after publishing. For that narrow niche, that’s a real swing in visibility, and it began with data instead of a guess.
Analyses like this tend to turn up two kinds of opportunities: keywords a competitor ranks for that you don’t touch at all, and keywords you already rank for, just several pages behind them. That second group is often the faster win, since you’re improving a page Google already half-trusts instead of starting from zero.
The Getaway Car: Turn Competitor Keywords Into Content, Fast
A keyword list only matters if you actually do something with it before your competitor notices the gap. This is where most people stall out. Analysis is easy. Execution is where heists fall apart.
This is where SirWritesALot comes in, the AI writing tool built by the same team behind SirLinksALot.
Start with keyword clustering. Feed in up to three competitor domains, and SirWritesALot pulls every keyword those sites rank for, often thousands at once, then automatically groups them by SERP overlap (SERP just means the page of results Google shows you). Keywords only get clustered together if Google already treats them as answerable by one page, not just because they sound similar. Instead of a messy spreadsheet, you get an organized content plan you can view as a kanban board, cards, or a table.
Once you’ve picked a cluster, SirWritesALot’s writing tools take over:
- An outline generator builds a structure straight from what’s already ranking
- A full draft writer produces a complete, SEO-aware article in minutes
- A live 0–100 content score benchmarks your draft against the actual top 10 competitor pages as you write
- An auto-optimize mode flags any topic your competitors covered that you missed
The whole point is speed. The gap you just found is only valuable while it’s still a gap. The faster you publish something genuinely better, the faster you’re the one collecting that traffic instead of them.
Picking Your Targets: Which Keywords Are Actually Worth Stealing
Not every keyword in a gap analysis deserves your time. Chasing all of them is how a heist turns into a mess. A smart crew picks targets carefully.
Search intent matters first. Is someone typing that phrase looking to buy, compare, or just learn something? Ranking for a keyword that doesn’t match what your page actually offers rarely converts, even from the top spot.
The volume-to-difficulty ratio matters second. A keyword with huge search volume but sky-high competition can take months to crack. A keyword with decent volume and low-to-medium competition can rank in weeks. Early on, the second option almost always wins.
Relevance to what you sell matters most of all. Traffic is nice. Traffic that turns into customers is the actual goal. A keyword only counts as a good target if the people searching it are the same people your business already serves.
One more thing worth saying plainly: the goal is never to clone a competitor’s article. Google rewards original expertise, real examples, and content that actually helps the reader, not a reworded copy. Use their keyword as the target. Use your own knowledge and voice as the weapon.
Ready to Make Your Move?
Here’s the recap: stop guessing at blog topics and start reading the data your competitors already handed you for free. Every keyword they rank for is a signal. Every gap is an opening.
The process gets simple once you’ve done it a few times. Run a gap analysis to find what you’re missing, cluster the keywords into a real content plan, then move fast enough to publish something better before anyone else catches on.
None of this requires breaking a single rule. It’s public data, read carefully and acted on quickly, which turns out to be something most sites never actually do.
If you want the full toolkit for this kind of work, SirLinksALot built its Keyword Gap Analysis Tool, along with SirWritesALot for the writing side, specifically so smaller sites could compete with the pages sitting on page one right now. The vault’s not as locked as it looks.
FAQs
Is it legal to analyse a competitor’s keywords?
Completely. You’re only looking at public search results and public ranking data, the same information anyone can see by searching Google themselves. No hacking, no scraping private data, nothing against any platform’s rules.
How many competitors should I analyse?
Three is a solid starting point: one direct competitor close to your size, and one or two bigger sites you’re aiming to catch up to. Much more than that and the data gets hard to act on.
How often should I run a keyword gap analysis?
Quarterly is a reasonable rhythm for most sites. Rankings shift and competitors publish new content, so a keyword that was out of reach six months ago might not be anymore.
Do I need to be technical to do this?
No. Tools like SirLinksALot’s Keyword Gap Analysis Tool and SirWritesALot’s clustering feature are built for marketers and business owners, not just developers. If you can read a spreadsheet, you can run this process.
What if my competitor notices and improves their content too?
That’s the nature of competitive SEO. It’s not a one-time move. Treat it as an ongoing habit rather than a single project, and you’ll usually be the one adjusting first.
