Free checker · Content and Writing
Content Gap Analyzer.
Compares your page against up to four competitors on length, subheadings and the phrases most of them use and you never do. Usually the fix is three subheadings rather than a rewrite.
The page that is not ranking as well as you would like.
Search the query you are targeting and paste the top two or three results. Up to four.
Check done
Want someone to fix what this found?
Finding a problem and fixing it are different jobs, and the second one is ours. Send the result over and you get back what it would take to put right — scoped and priced, from the person who would do the work, within one business day.
What this tool measures
Fetches your page and the pages beating you, and lists what they cover that you do not.
This is the check behind most “your content is thin” verdicts, done explicitly rather than asserted. A competitor outranking you because they answer the question more completely is the most common reason to lose a position and the most fixable, and the fix is usually three subheadings rather than a rewrite.
What it compares is terms, not meaning. A phrase that appears repeatedly on most competing pages and never on yours is strong evidence you have skipped a subtopic. It is not proof, and it is emphatically not a list of words to sprinkle in — doing that produces exactly the thin, keyword-shaped page this is meant to prevent.
How to use it
Enter your page, then search the query you are targeting and paste the top two or three organic results. Skip the directories and aggregators unless you are genuinely trying to compete with a directory — their pages are built on a different model and comparing against them will mislead you.
Three competitors is the useful number. One tells you about one company's house style. Four or more starts including pages that are ranking for a different reason.
How to read the result
Start with the length comparison, and read it as a question rather than a target. If your page is comparable in length and still losing, length is not the problem and no amount of adding words will fix it — look at the coverage list instead. If it is under half the average, the question probably has not been answered.
The phrase list is the substance. Each entry appears at least twice on most of the competing pages and never on yours. Read each as a subtopic: “payment gateway” appearing on every rival page and none of yours means they explain payments and you do not.
The single-word list is a weaker signal, because one word rarely corresponds to one subtopic. It is useful for spotting a whole theme you have missed rather than a specific gap.
Their subheadings are listed at the bottom deliberately unranked. They are not a template. Read them as the questions each page chose to answer, then decide which of those your reader would also ask — which is often most of them and never all of them.
What to do next
Group the gaps into two or three themes and write a section for each. A section is a heading plus a few paragraphs that genuinely answer something. That is what closes a content gap; a sentence containing the missing phrase is not.
Then leave the page alone for a month. Content changes take time to be recrawled and reassessed, and editing again in week two makes it impossible to tell which change did anything.
If your page already covers everything on the list and still loses, the cause is elsewhere: links, or a page type that does not match what the query wants. That is a genuinely useful thing to establish, because it stops you rewriting a page that was never the problem.
Questions people ask
Should I just add all the missing phrases to my page?
No, and doing that is the failure mode this tool exists to prevent. Each phrase stands for a subtopic. Write the section, and the phrase appears on its own. A page carrying forty inserted phrases and no new substance is worse than the page you started with.
Does my page need to be longer than theirs?
No. Length is a symptom of coverage, not a cause of ranking. A shorter page that answers the question completely beats a longer one that circles it. The length bar is there to tell you whether the gap is plausibly about substance, not to set a target.
Why can't it fetch some competitor pages?
Some sites block automated requests, and some sit behind a bot-protection service. Nothing can be done about that from here. Pick a different result from the same search — there are usually ten.
Does this see content added by JavaScript?
No. It reads the HTML as served, with nothing executed. That is also what most crawlers get on the first pass, so a competitor whose content is invisible here is worth noticing rather than working around.
