Plagiarism Checker
Free Plagiarism Checker: detect duplicate content patterns and estimate originality. Privacy-friendly with optional web overlap sampling.
Plagiarism Checker
Paste or type your content to estimate originality. We compute internal duplication and sample the web for overlap signals.
Check your article, blog post, essay, or product copy for duplicate content signals before publishing. This free plagiarism checker estimates originality by combining internal duplication analysis (repeated phrase patterns) with optional sampled web overlap checks.
Why it matters for SEO: search engines reward originality, depth, and unique value. Duplicate or near-duplicate passages—especially across multiple URLs—can dilute rankings and confuse canonical intent. Use this tool to spot risky repetition and rewrite with fresh angles.
How it works: we tokenize your text, compute shingles (sliding windows of 6–7 words), and measure how often the same shingles repeat internally. Then we optionally sample a small subset of shingles as exact-match queries against the web to detect potential overlap. The result is an estimated originality score along with internal and external ratios.
Privacy-first: input is processed to compute statistics and then discarded. If a search engine API key is not configured, the web-overlap portion is skipped while internal analysis still runs fully locally on the server.
Editorial guidance: originality isn't only about wording—it's also about angle, examples, and intent satisfaction. If overlap is detected, consider adding firsthand data, unique visuals, industry-specific frameworks, or localized guidance to stand out.
US market nuance: cite authoritative US sources (e.g., gov, edu, reputable research) when making claims, and include stateside terminology (zip code, sales tax, ADA, HIPAA) where relevant to reinforce topical and geo relevance.
UK nuance: prefer UK spellings (optimise, organisation), reference HMRC, ICO, ASA guidance, and use UK-specific examples (postcodes, VAT, GDPR UK) when targeting British audiences.
India nuance: incorporate local regulations (GST, RBI, MeitY), pricing in INR, regional examples (Tier-1/2 cities), and linguistic clarity for multilingual readers; linking to Indian standards can boost geo signals.
Australia nuance: address GST, ASIC, .au domains, and local compliance. Use AU spellings (optimise, recognise) and case studies relevant to Australian SMBs or agencies to improve resonance.
Content depth strategy: shift repetitive how-to steps into concise checklists, and expand with comparison tables, annotated screenshots, and pitfalls unique to your stack or region.
Original research: even small-sample polls, pricing studies, or benchmark timings (with clear methodology) help differentiate. Include the date, sample size, and limitations.
Dedup against your own site: near-duplicate service pages or blog posts can cannibalize rankings. Consolidate, canonicalize, or differentiate intent to avoid self-competition.
E-E-A-T reinforcement: add bylines, credentials, and last-reviewed dates. Link to author profiles and cite primary sources. Include maintenance notes for versioned tech.
Refresh cadence: set a quarterly content audit. Replace stale metrics, add new screenshots, and update internal links to current tools and product features.
Distribution planning: before publishing, prepare 3–5 angles (Twitter thread, LinkedIn carousel, short video). Original narratives reduce overlap and attract organic links.
Editorial calendar alignment: map overlapping drafts to a single canonical pillar and support it with clusters. Use this checker during outlines to avoid re-writing what already exists.
Snippet uniqueness: write meta titles and descriptions that reflect the page’s unique promise. Avoid repeating the same headline formulas across multiple URLs.
Entity coverage: include entities, people, places, organizations and products that are truly relevant to your angle. Superficial name-drops without analysis do not increase originality.
Topic saturation: measure whether your page adds new subtopics, examples, or steps that competitors miss. Originality can be topical depth, not just rewritten text.
Process transparency: when you cite research, describe methodology and link to sources. Transparent methods boost trust and perceived originality.
Media originality: embed your own diagrams, screenshots, code snippets, and data tables. Image hashes, alt text, and captions can signal unique media assets.
Versioning and changelogs: maintain a changelog section that lists meaningful updates (date, what changed, why). Freshness with substance improves differentiation.
Local SEO fit: for city or country pages, include local regulations, costs, service availability, and vendor lists that reflect on-the-ground reality. Avoid generic boilerplate.
Ecommerce angle: product descriptions should include hands-on details (fit, materials, sizing behavior, compatibility), and care instructions—details no one else mentions.
SaaS angle: show internal workflows, admin screens, and edge cases. Explain failure modes and how to recover. Provide integrations that competitors don’t cover.
Analytics workflow: track internal duplication across your own library with a content inventory spreadsheet. Use this tool to evaluate consolidation candidates.
Editorial debt: plan refactors for legacy content that drives traffic but overlaps with newer pages. Consolidate thin posts into comprehensive evergreen guides.
Internationalization: when translating, adapt examples, currencies, holidays, and legal constraints to the region; avoid one-size-fits-all translations that read like copies.
Compliance: add disclaimers where needed (legal, medical, financial). Clarifying scope differentiates your guidance from generic how-tos and builds trust.
User feedback loop: include a feedback widget to capture gaps and context from readers; update the page and credit contributors—this steadily increases originality over time.
Link earning: original frameworks and calculators earn links naturally. Consider adding a mini-tool, template, or dataset to pair with the article.
Promotion: pitch unique findings to newsletters, communities, and journalists. The more your work is referenced, the more it stands apart from commodity content.
Operational playbook: standardize originality checks in your definition of done (DoD). Require: unique angle statement, 3+ unique examples, 1 original visual, and refreshed internal links.
Editorial QA: have a second editor verify that each major section adds something qualitatively new. If not, cut or rework it before publishing.
Competitor gap-mapping: collect H2s/H3s from top results and highlight missing topics you can uniquely cover. Turn gaps into sections with original examples.
SERP feature alignment: if the query triggers People Also Ask or videos, consider adding Q&A blocks and short clips that answer adjacent intents in your own words and visuals.
Information gain: summarize what your page adds compared to the best three results. Aim for at least one significant new idea, method, dataset, or tool.
Template differentiation: if you publish templates (SOPs, checklists), annotate each step with rationale, failure modes, and measurable outcomes to avoid generic sameness.
Refuting misconceptions: address common myths in your niche and provide citations. Original myth-busting boosts perceived expertise and uniqueness.
Work-in-public: document how you built something (screenshots, logs, mistakes). Honest build logs are inherently original and earn natural links.
Localization execution: show localized screenshots (currency, date formats, compliance toggles). Pair with region-specific caveats to prove firsthand use.
Technical depth: include edge cases and trade-offs. Surface constraints and when not to use a given approach to move beyond surface-level guides.
Editorial analytics: track originality score alongside engagement (scroll depth, time on page). Correlate improvements to determine which tactics move the needle.
Lifecycle: when sunsetting overlapping pages, 301 redirect to the canonical resource and fold the best bits into it with a note on what changed and why.
Examples and Best Practices
Rewrite tactics that preserve meaning
- Swap generic claims for concrete, sourced numbers (with date and sample size).
- Replace listicles with step-by-step frameworks tied to outcomes.
- Localize with geo-specific regulations, terminology, or providers (US, UK, IN, AU).
- Add screenshots, prompts, or templates you actually use in production.
- Synthesize 3–5 reputable sources into a new, clearer model rather than paraphrasing one.
Publishing checklist
- Run the checker and note internal duplication ratio (<20% is a good baseline for most articles).
- Scan web-overlap ratio; if high, rewrite sections with new examples or data.
- Add original images/diagrams and alt text that reflects the unique content.
- Ensure canonical and noindex rules are correct for variations and print views.
- Link to related tools and guides to deepen topical coverage and reduce pogo-sticking.
Originality boosters by content type
- How-to: include a failure case and recovery plan most guides omit.
- Comparison: define criteria and weights; disclose methodology and test data.
- Case study: share metrics, timeline, decisions considered, and what you’d change.
- Reference guide: add decision trees and cheat sheets for quick application.
- Opinion: state a clear thesis and back it with experiences and citations.
- News reaction: add industry context, likely impacts, and concrete next steps.
Geo-optimization ideas
- US: ADA, HIPAA, FTC endorsements, sales tax thresholds; embed US screen examples.
- UK: ICO guidance, ASA rules, VAT rates; local screenshots and pricing in GBP.
- IN: GST, RBI norms, UPI flows; INR pricing and Indian vendor examples.
- AU: ASIC, ACCC, GST; AUD pricing and AU-specific form examples.
- Localization: adapt holidays, address formats, units (imperial/metric).
Team workflow
- Outline → originality plan → draft → internal-dup check → peer review → publish.
- Set a pre-publish gate: at least 1 new dataset, 2 new examples, and 1 original diagram.
- Quarterly consolidation review to reduce cannibalization and keep content fresh.
