Competitor content gaps: run an actionable gap analysis with 30 queries

Bottom line first: The output of a gap analysis isn’t a report, it’s a 12-week writing schedule. Build a query set from 20 core product terms plus 10 buyer-question terms, then check each one against how you and two competitors rank in Google’s top 10. Gaps come in only three kinds: no content, weak content, or wrong format. Rank what to fill first by three factors — search volume, commercial value, and how hard it is to produce — and start with the batch that’s valuable and where competitors are weak too.

1. The value of a gap analysis isn’t the report, it’s the schedule

First, draw the boundaries. Two related topics have already been covered on this site: one post on mining on-site search terms, which looks at what users search after they land on your site — that’s your own demand gap; another on five checks for competitors in AI answers, which looks at who engines like ChatGPT mention in their answers. This post covers only the third piece: on the Google search side, which queries competitors have content for and you don’t, whether they’re stronger than you or just earlier than you, and how to order the work of filling the gaps.

The most common way a gap analysis fails is producing a report dozens of pages long, listing ranking comparisons for two or three hundred terms, after which nobody knows what to write next week. There’s only one test for whether a gap analysis worked:Can you list the articles to write over the next 12 weeks on the day it’s done?

Output format	What it looks like	Who reads it	Is it useful
Ranking comparison report	A big table of 200 terms against 3 competitors	Nobody reads it through	Low — data but no decisions
Gap matrix	30 queries plus gap type, one page	Content owner	High — it circles the topics to fill
Writing schedule	12 weeks, one article a week, mapped to queries	The writers	High — the matrix’s only useful output

The difference between a report and a schedule: a report answers “what’s the situation,” a schedule answers “what do we work on next.” A gap analysis creates no value on its own; the content you fill in does. So from the moment you build the query set, every step should converge on the end goal of landing on the calendar.

2. How to build the query set: 20 product terms plus 10 question terms

The query set is the entire input to a gap analysis — build it wrong and everything downstream is wrong. I suggest fixing the 30 terms as follows:

Keyword type	Videos	Source	Examples (precision machining)
Core category terms	10	Your own product line names plus competitor navigation menus	CNC machining services, injection molding supplier
Spec and application terms	10	What buyers say in inquiry emails, plus spec pages	5-axis aluminum parts, medical grade molding
Buyer question terms	10	Inquiry email wording plus People Also Ask	how to quote CNC parts, MOQ for custom molding

The three sources don’t carry equal weight.Core category terms guarantee coverage, spec terms capture traffic with buying intent, and question terms feed AI snippets and related questions. Drop any one type and the matrix tilts: category terms alone miss your best-converting long tail, question terms alone miss the main category battleground.

Two practical details. First, inquiry emails are your highest-quality term source — build your set from how buyers actually ask, not from factory jargon. Second, manually page through your competitors’ blog index pages; whatever they published in the last two months is probably the query they’re betting on. Check your 30 terms against their index and fill the gaps.

Build the query set once, save it as a fixed table, and from then on only add or remove terms in each review — never start over. If you’re building the term list layer from scratch, see our article on keyword research by search intent This article assumes you already have a base term list; the gap analysis ranks on top of it.

3. Comparison matrix: three players, top 10, three gap types

How to build the matrix: search each query once in an incognito Google window, and note whether the top 10 includes you, Competitor A and Competitor B, and what format each one uses — product page, article, guide, or nothing at all.

There are only three gap types. Don’t invent a fourth:

Gap type	Test	What it looks like	What to do
No content	No URL of yours in the top 10, and no matching content on your site	A competitor holds the spot with an article, and you have no matching page	Write new, following the intent of the competitor’s stronger article
Content exists but is weak	You have a URL ranking in the top 20, but more than 5 places behind a competitor	Word count, update year and original material are clearly weaker than the competition	Refresh the existing page, don’t write new
Wrong format	You have content but can’t crack the top 20, and the top 10 is all in a different format from yours	A competitor holds the spot with a comparison guide, while you only have a spec table	Redo it in the right format; 301 the old page or repurpose it

The third type is the easiest to miss. Many factories react with “I already have a page for that, so it’s not a gap” — but a page in the wrong format is effectively absent from search results. When a buyer searches how to choose, they want a decision framework. Hand them a spec sheet and you’ll never climb the rankings.

Record the date alongside every term as you compare. Three months later, when you review, you’ll need to know where it ranked at the time — a matrix without dates can’t be compared.

4. Three hard lines for calling something “weak”

“Content exists but is weak” can’t be a gut call. Hold it to three hard lines:

How to tell	Passing standard	Action if below the line
Information density line	Body copy of 1,200+ words, including at least 3 specific numbers (specs, timeframes, ranges)	Add numbers, cut adjectives
Timeliness	The article cites data, years, or case studies from within the last 24 months	Update the data and years
Exclusive material	Includes at least 1 thing competitors can’t offer: test data, production line photos, internal checklists, original charts	Add exclusive material, or pick a different topic for this article

Hitting fewer than two of the three lines means the page is weak. The upside of this standard is that it’s defensible: use the same yardstick before and after the revamp, and there’s no argument about whether the refresh was done properly.

Of the three lines, exclusive material carries the most weight. The gap on the first two can be closed with effort; exclusive material can’t be — which is why queries where “you have exclusive material and competitors don’t” should come first in the fill-in order. Writing content isn’t the hard part; deciding what to write is. For how to schedule production capacity, there’s an article on the site Capacity planning for a one-person team, which you can use alongside the scheduling section below.

5. Fill-in order: three-dimension scoring

The matrix usually turns up 10 to 15 queries to fill. Filling them all isn’t realistic, so you need an order. Score each on three dimensions, 1 to 3 points each:

Dimension	1 point	2 points	3 points
Search volume	Under 50/month or unknown	50–500	Over 500, or a core category term
Commercial value	Pure awareness, far from an inquiry	Influences selection	Directly tied to an inquiry request
Effort to fill	Needs multiple people or new data collection	Done within a day	Doable within half a day (mostly a refresh)

Total score out of 9.Do anything scoring 7+ first, queue 5–6, and put anything 4 or below on the to-do list without committing to a date.

Here’s a sample set (numbers are illustrative — fill in your own matrix):

Query	Search volume	Commercial value	Effort to fill	Total	How to handle it
CNC machining services (no content)	3	3	2	8	Week 1
how to quote CNC parts (no content)	2	3	3	8	Week 2
5-axis aluminum parts (exists but weak)	2	3	3	8	Week 3
injection molding vs 3d printing (wrong format)	3	2	1	6	Week 6
Surface finishing encyclopedia (no content)	2	1	2	5	To-do

Watch out for the order effect in scoring:A combination of “commercial value 3 + effort to fill 3” outranks “search volume 3 + commercial value 1.” B2B traffic is thin to begin with, so one long-tail query that leads straight to an inquiry is worth writing before ten that only build awareness.

6. Two edge cases: misreading attribution, and when not to bother

The most expensive mistake in a gap analysis is bad attribution: you see a competitor ranking #2, assume their content is good, and go copy it. Ranking is a blend of content, domain authority, and site age — separate them before you judge:

Symptom	Check first	Likely conclusion	Action
Competitor page is thin but ranks #1–3	Their site age and backlink volume	Domain authority is carrying it	Don’t copy the page — write at higher density instead, and expect 6–12 months
Competitor page really does have high information density	Compare information points paragraph by paragraph	A genuine content gap	Match them and add a layer of exclusive material they don’t have
The top 10 is entirely big platforms	Check whether it’s an e-commerce platform or an encyclopedia-type site	the term is monopolized	Work around it: rewrite as a more specific spec term or question term
A competitor’s post from 3 months ago ranks #4	Publish date	freshness advantage	Watch it for a quarter; no rush to benchmark

A practical test:Count the factual information points on the competitor’s page one by one (numbers, specs, conditions, cases). A page with 30+ information points is genuinely strong; a page with fewer than 10 ranks high only because of domain authority. The former is worth benchmarking, the latter is worth beating — usually a 1,500-word article with 25 information points can overtake it.

Another boundary is the conditions under which this applies. Stop when you hit any of these four:

Condition	Why	Replacement move
Fewer than 30 pieces of on-site content	No samples in the “exists but weak” column, so you can’t see the real gap	Build out the basic pages by product line first
The competitor is an industry giant	All ranking differences come from domain authority; the comparison yields nothing actionable	Study only its content structure, skip the ranking comparison
Category terms are monopolized by platforms	No independent site in the top 10	Switch to gap analysis on question terms and spec terms
The product line will change drastically within three months	The content you add becomes obsolete with the redesign	Wait until the product line is finalized, then analyze

30 articles is the minimum threshold for this work. At an earlier stage, put the same effort into filling out the factual density of your product pages — the payoff is much higher. Gap analysis amplifies structural problems in content you already have; when there isn’t enough content on the site, there’s nothing to amplify.

7. Deliverables and review: a one-page matrix, a 12-week schedule

All this work produces just two files. The first is the matrix, with six fixed columns:

Column	What to fill in
Query	The buyer’s exact words, unedited
Search volume	Midpoint of the tool’s range
Our status	No content, exists but weak, wrong format, covered
Competitor A status	Same criteria as above
Competitor B status	Same criteria as above
Score and action	Three-dimension total score plus scheduled week

The second is the schedule. Here’s a 12-week sample outline:

Week	Task	Target queries	Labor
1–2 weeks	Two core category-term articles	Category terms scoring 8 or above	2 days each
Weeks 3–5	Three question-term articles	Questions phrased the way buyers ask them	1.5 days each
Weeks 6–8	Refresh three weak pages	The “exists but weak” group	0.5–1 day each
Weeks 9–10	Redo two pieces in the wrong format	The “wrong format” group	2 days each
Weeks 11–12	Buffer plus first-month data review	—	Half a day

The schedule maps directly to capacity: at the normal pace of one person producing 1–2 articles a week, 12 weeks covers about 10 articles — exactly the fill-in volume a 30-term analysis usually produces. If you leave no buffer, execution falls apart by week 3, so the last two weeks must stay open.

Keep the review cadence on two cycles:

Cycle	Action	Output	Time
Quarterly	Incremental comparison: 10 new queries plus a ranking check on pages filled in last round	Incremental matrix plus schedule tweaks	Half a day
Every six months	Full rerun: update all 30 terms in the matrix, re-check the competitor list	New matrix plus a new 12-week schedule	1–2 days
Annually	Reselect the competitor list once	Swap out 0–1 competitors	2 hours

Two rules. First,Don’t start a new round until the last one is finished— A gap analysis is only good for one quarter’s schedule. Stack one schedule on top of another and you effectively have none. Second, when you check the pages you filled in, look at a full 90 days. Long-tail B2B keywords typically take 6 to 12 weeks to settle into a stable position, so week 4 rankings tell you nothing.

FAQ

How many competitors should I use for comparison?

Two, three at most. They have to meet all three criteria: their product line overlaps with your target market, their site has a comparable content volume of 30 to 300 posts, and they’ve published something in the past six months. Skip the industry giants — their rankings come from domain authority, and you can’t replicate what they do anyway. Two gives you a clean comparison with manageable effort. Past three, the matrix costs double to maintain and you stop learning anything new.

Is 30 queries enough?

30 is a starting point, not a ceiling. Once your site has more than 100 posts, you can expand to 50, but never analyze more than 50 at once — you’re checking each keyword by hand, and one person can only get through 15 to 20 in a day. Beyond that, either quality drops or it drags on for three weeks. Better to start with 30 and get the schedule running, then expand during your six-month full review by adding the new keywords to an incremental round.

Can I do this without paid tools?

Yes, and the quality of your conclusions won’t suffer. Search each keyword in an incognito browser and record the top 10 results — about 3 to 4 hours for 30 queries. Get search volume ranges from the free tier of Google Keyword Planner. For competitor content lists, just browse their blog archive pages. Paid tools save you time, not insight. If your monthly budget is tight, buy a rank tracker first to monitor your filled-in pages, and do everything else by hand.

What if competitors have so much authority I can’t compete?

Attribute the gap before you draw conclusions. Go through each competitor page ranking in the top 10 and count its factual information points. More than 30 means they’re genuinely strong — follow their structure, add a layer of exclusive material they don’t have, and expect to reach the top 20 in 6 to 12 months. Fewer than 10 means authority is carrying them — write a denser piece on the same topic and you’ll usually overtake them within a year. If the top 10 is all e-commerce platforms or encyclopedia sites, skip those queries entirely and rewrite them as more specific spec or question terms.

How often should I run a gap analysis?

A full analysis every six months, an incremental one every quarter. The incremental round covers 10 new queries plus a position check on the pages you filled in last time — half a day’s work. Don’t do it monthly. A gap analysis produces one quarter’s schedule, and if you redo the analysis before that schedule is finished, the two schedules overwrite each other and neither gets executed. The only exceptions are a major product line change or a new target market — in those cases, rerun it immediately.

What’s the difference between a gap analysis and keyword research?

Keyword research answers “which terms should we cover?” and produces an intent-layered keyword list. Gap analysis answers “which of these do I fill first, and who am I writing against?” and produces a 12-week schedule. The order is: keyword list first, then gap analysis. The list takes you from zero to one; the gap analysis ranks what you have. Skip the list and go straight to gap analysis, and your query set is guesswork. No matter how tidy the matrix looks, you may be targeting the wrong topics entirely.

Final thoughts

Gap analysis easily turns into a report that looks highly professional but nobody ever opens a second time.To judge whether it worked, look at one thing only: by the end of the day, is it already decided what you’ll write for the next 12 weeks? The matrix is the means; the schedule is the deliverable.

Here’s the starting move I recommend: spend one day this week building a 30-term query set, spend two days next week running the comparison matrix, and in week three put the top 5 scored topics on the calendar. Don’t agonize over the competitor list. Two companies with overlapping product lines and comparable content volume are enough. Get it running first, then swap them out.

One line worth remembering: gap analysis doesn’t answer “where are we worse than our competitors” — it only answers “which 10 posts do we write first in the next 12 weeks.”
