Free Missing Keywords Tool
Find the keywords your site should be targeting and does not. We read what your pages are actually about, then surface the gaps — ranked by commercial intent and how completely you are ignoring them.
Why find your keyword gaps?
Grounded in real pages
Gaps come from what competitors actually publish, or from your own service vocabulary — not from a database you cannot verify.
Intent-tagged
Every keyword is labeled Local, Commercial, Comparison or Informational, so you build the ones with buyers behind them first.
Coverage check
See what your site currently tells search engines it is about. If that list is wrong, fix your pages before writing anything new.
Ready to brief
Each gap comes with the page type to build. Export as CSV or copy the whole thing as a content brief.
How it works
Enter your website
Add your city if you serve a local market, and up to three competitors for a true gap analysis.
We map your coverage
We crawl your pages, extract the service terms you already rank around, and compare them against how buyers actually search.
Get your gap list
15 to 40 keywords ranked by opportunity, with intent, difficulty and the page type to build for each.
Why this matters
Every site has a vocabulary. Whatever your pages repeat in their titles, headings and body copy is what search engines and answer engines believe you are about. If a phrase never appears anywhere on your site, you are not competing for it — you are not even in the race.
This tool works in two modes. Give it competitor domains and it does a true gap analysis: crawl them, crawl you, and surface the phrases they use repeatedly that never appear on your pages. Give it just your site and it works in discovery mode: it extracts the services you actually sell from your own titles and headings, then expands them across the intent and location patterns real buyers use, keeping only the combinations your site never mentions.
Both modes are grounded in what is really on the pages. Nothing here is pulled from a keyword database you have no way to verify.
Discovery mode versus competitive mode
Competitive mode is the stronger signal, because a real competitor has already made a bet about what is worth writing. When two or three of them cover a topic you do not, that is evidence rather than inference.
Discovery mode is what you use when you do not yet know who your competitors are, or when you want to check whether your own service vocabulary has been expanded properly. It takes the two and three word service phrases your pages already establish — “google ads”, “roofing seo”, “pool maintenance” — and combines them with the modifiers buyers actually type: cost, pricing, near me, best, for small business, how much does X cost, plus your city and the markets around it.
It then discards every combination that already appears somewhere on your site. What remains is genuinely uncovered ground.
Reading intent and difficulty
Every gap is tagged with intent. Local and Commercial keywords have buyers behind them and should be built first. Informational keywords build topical authority and feed AI answers, but they convert slowly and should not be the whole plan. Comparison keywords sit in between and often convert well when you have something genuinely differentiated to say.
The difficulty figure is a structural estimate — derived from phrase length, intent type and whether a location narrows the field — not a live competition metric. It is useful for sorting a list into “start here” and “later”, and it is honest about being an estimate. If you connect a keyword data provider, the tool replaces those estimates with live search volume, CPC and competition figures.
From list to published pages
A keyword list is not a content plan. The step that matters is grouping: close variants belong on a single page, because splitting them creates thin pages that compete with each other and dilute the authority you were trying to build.
For each page you do build, make the target phrase a real subheading and answer it directly in the first two sentences underneath. That single habit is what gets a page lifted into featured snippets and AI answers, and it costs nothing extra to do while you are writing anyway.
Then link it. A new page nobody links to internally can take months to be discovered, and sometimes never is.
Best practices
- Add two or three real competitors — competitive mode is a much stronger signal than discovery mode.
- Build Local and Commercial intent keywords first.
- Group close variants onto one page rather than splitting them.
- Make the target phrase a literal H2 and answer it in the first two sentences.
- Link every new page from at least two existing pages.
- Re-run after publishing to confirm the gap actually closed.
Common mistakes to avoid
- Publishing one thin page per keyword and cannibalizing your own rankings.
- Chasing high-volume head terms with no realistic path to ranking for them.
- Ignoring location modifiers when you serve a defined geographic market.
- Treating the keyword as something to insert rather than a question to answer.
Frequently asked questions
Where do the missing keywords come from?
In competitive mode, from phrases your competitors’ pages use repeatedly that never appear on yours. In discovery mode, from your own service vocabulary expanded across the intent and location patterns buyers use — with every combination that already appears on your site filtered out.
Are search volumes real?
Not by default. Without a keyword data provider connected, opportunity and difficulty are structural estimates derived from phrase length, intent and location specificity. We label that clearly rather than presenting invented numbers as fact. Connect a provider such as DataForSEO and the tool swaps in live volume, CPC and competition.
How many keywords does it return?
Between 15 and 40, your choice. The list is deliberately diversified across seed topics and modifier patterns so you get a usable spread rather than twenty variations of one phrase.
Why is my brand name excluded?
Because you already rank for it and it is not a gap. We filter out both your brand tokens and your competitors’ so the list stays actionable.
The topics it says I cover look wrong. What does that mean?
It means your pages are telling search engines a different story than you think they are. That list is derived from your own titles, headings and repeated body phrases — if it does not match what you sell, fixing your on-page copy is a higher priority than any keyword on the gap list.
Does this replace a proper keyword research tool?
No. It finds gaps in coverage, which is a different job from sizing demand. Use it to decide what to write about; use a volume tool to decide how much to invest in each one.
Will this surface local keywords like “plumber Sarasota”?
Yes, and more usefully it surfaces the ones you would never think to check. Because the tool reads what your competitors actually publish rather than pulling from a keyword database, it picks up neighborhood and municipality names — Lakewood Ranch, Siesta Key, Osprey, Palmer Ranch — that have real customer intent but too little search volume for a keyword tool to ever suggest them. In local markets those long-tail location phrases are frequently where the cheapest wins are.
