Enter your keywords and competitor keywords to identify content gaps. Venn diagram visualization shows unique and overlapping topic coverage.
Start with two keyword inventories: topics your content covers and topics associated with a competitor. Keyword Content Gap Finder separates the entries into your-only, shared, and competitor-only groups, then maps those groups in a Venn diagram so differences are visible at a glance. The important surprise is that it analyzes only the terms you enter. It does not inspect websites, estimate search demand, or prove that a competitor ranks for a phrase. A competitor-only term is a list difference to investigate, not automatically an SEO priority.
A concrete input and expected output from the current implementation.
Input
Your keywords: content strategy email marketing Competitor keywords: content strategy influencer marketing
Expected output
Your-only: email marketing (1 keyword). Overlap: content strategy (1 keyword). Competitor-only: influencer marketing (1 keyword). The Venn diagram therefore has one keyword in each populated region.
Each input contains two keywords, and content strategy appears in both. Removing that shared entry leaves one exclusive keyword on each side and three distinct keywords across the combined lists.
Supply one keyword set for your coverage and another for the competitor's coverage. The tool classifies each submitted term by its relationship to those two sets: present only in yours, present in both, or present only in the competitor's. The competitor-only group represents possible content gaps, while the your-only group shows differences in the opposite direction.
The intersection represents keywords recognized in both submitted inventories. The non-overlapping sections contain terms confined to one input, making the direction of each difference explicit. The diagram describes topic-list membership, not relative ranking strength, traffic, authority, or content quality. Read its regions as a compact comparison of the supplied terms rather than as a search-performance report.
No. Its role is to compare the keyword inventories entered into the two sides. You must obtain the competitor terms separately and decide which keywords represent your own coverage. The resulting diagram does not independently verify that either website has a relevant page, ranks for a listed phrase, or receives search traffic from it.
No. Each such keyword is a candidate gap, not a recommendation. Check whether it fits your audience, offerings, search intent, and existing pages, then assess demand and competition separately. A phrase may be absent from your list because it is irrelevant, too broad, semantically duplicated by another topic, or deliberately outside your strategy.
