How to Do a Keyword Gap Analysis (Step-by-Step)

A keyword gap analysis finds the searches your competitors rank for and you don't. It's one of the highest-leverage moves in SEO because it skips the guesswork: instead of brainstorming topics and hoping they have demand, you let proven competitors hand you a list of keywords that already drive traffic in your market.

This guide walks through the whole process — what a gap is, how to find your real competitors, how to pull the gaps, and how to decide which ones are actually worth chasing.

What is a keyword gap?

A keyword gap is any query where:

• One or more of your competitors ranks on page one, and
• You either don't rank at all, or rank so low (page 3+) that you get no traffic.

Each gap is a piece of demand your competitors are capturing and you're missing. Close enough of them and you don't just add traffic — you start taking it from the people currently winning it.

There are two flavors worth separating:

• Shared gaps — keywords several competitors rank for but you don't. These are usually core topics for your category. High confidence they matter.
• Unique gaps — keywords just one competitor ranks for. These can be hidden gold (an angle nobody else spotted) or noise (irrelevant to your business). Treat with more scrutiny.

Step 1: Identify your real SEO competitors

Your SEO competitors are not always your business competitors. The site outranking you for "best CRM for small teams" might be a blog or a review site, not a rival product.

To find your true SEO competitors:

1. List 5-10 of your most important target keywords.
2. Search each one (in an incognito window) and note which domains repeatedly appear on page one.
3. The domains that show up across many of your target searches are your real SEO competitors — those are the ones to gap against.

Pick 3-5. More than that and the analysis turns to mush.

Step 2: Pull each competitor's ranking keywords

For every competitor, you need the list of keywords they currently rank for. You have a few options:

• A dedicated SEO tool (Ahrefs, Semrush, etc.) — enter the competitor's domain, export "Organic Keywords."
• Google Search Console — only shows your data, so it tells you where you already rank (useful for the next step), not competitors'.
• An automated tool that does competitor discovery and keyword extraction for you, so you skip the manual exports entirely.

Export each competitor's keyword list to a spreadsheet, one tab per competitor.

Step 3: Subtract what you already rank for

Now overlay your own ranking keywords (from Search Console or your tool) and remove them. What's left is the raw gap: keywords competitors rank for that you don't.

A quick way to do this in a spreadsheet: put all competitor keywords in one column, your keywords in another, and use a lookup to flag any competitor keyword that doesn't appear in your list. Those flagged rows are your gaps.

Step 4: Filter for keywords worth chasing

A raw gap list is too long and full of junk. Filter it down with four lenses:

1. Relevance. Would this keyword bring someone who could actually become a customer? Cut anything off-topic, no matter the volume.
2. Search volume. Enough demand to be worth an article. (Low volume can still be worth it if intent is high — a "best [your product] for [niche]" query converts even at 90 searches/month.)
3. Difficulty vs. your authority. A new site can't win high-difficulty head terms yet. Sort by difficulty ascending and start where you can realistically rank.
4. Intent. Match the keyword to where the searcher is — informational ("how to…"), commercial ("best…", "vs", "alternative"), or transactional. Bottom-funnel commercial gaps usually pay back fastest.

The output of this step is a prioritized list: the gaps that are relevant, have demand, are winnable for your domain right now, and match a clear intent.

Step 5: Cluster the gaps into topics

Don't write one article per keyword — you'll create thin, cannibalizing pages. Group related keywords into topic clusters and assign one strong article per cluster, targeting the head keyword and naturally covering the variations.

For example, "keyword gap analysis," "how to find competitor keywords," and "content gap analysis" all belong to one cluster, covered by one comprehensive guide (like this one) rather than three competing posts.

Step 6: Write, publish, and link

For each prioritized cluster:

• Write content that genuinely beats what's currently ranking — more useful, more specific, more current.
• Link new posts to your money pages and to each other to build topical authority.
• Publish, then track impressions and position in Search Console over the following weeks.

The shortcut: automate the whole loop

Steps 1-5 are powerful but tedious — exports, spreadsheets, lookups, filtering. This is precisely the loop SEO Wires automates. You give it your URL; it handles competitor decoding, pulls the keywords your rivals own and you don't, and hands back an automated topic roadmap already clustered and ranked by opportunity — then writes the article for each topic, in your brand voice, ready to publish.

So you can run the manual process above when you want full control, or let the pipeline do the analysis-to-article work for you. Either way, the strategy is the same: let your competitors tell you what to write next.

Frequently asked questions

What is the difference between a keyword gap and a content gap?
A keyword gap focuses on specific search queries competitors rank for and you don't. A content gap is broader — entire topics or subtopics your competitors cover and you haven't. A keyword gap analysis is usually how you discover content gaps.

How often should I run a keyword gap analysis?
Quarterly is a good cadence for most sites. Rankings shift, competitors publish new content, and new gaps open up. Run it more often if you're publishing aggressively or in a fast-moving niche.

Can I do a keyword gap analysis for free?
Partially. Google Search Console (free) shows where you rank. Manually searching your target keywords reveals competitors. The tedious part — pulling competitors' full keyword lists — usually needs a paid tool or an automated service.
