What Is SEO Plagiarism?

Plagiarism in SEO involves copying content without attribution or permission in an attempt to rank in organic search results.

It can be intentional or unintentional.

Some common types of plagiarism in SEO include:

• Stealing contentfrom competitors without citing or linking back to the original creator’s work
• Using exact wording from other search results without rephrasing or citing
• Changing only a few words to make content appear original (i.e., content spinning)
• Using AI-generated writing that’s highly similar to what other sites have published
• Publishing the same content on multiple sites you own instead of creating unique content for each

How Can Plagiarism Affect SEO?

Plagiarism intended to manipulate search results is against Google’s spam policies and can lead to ranking lower or getting removed from Google’s index.

Plagiarized content can also hurt users’ trustbecausemost people value original insights and expertise.So, users may stop visiting a site or interacting with it if they find out it engaged in plagiarism.

How to Proactively Prevent Plagiarism in Your Own Content

Prevent plagiarism in your content by citing your sources, checking for plagiarism while editing, vetting your writers, and using AI tools carefully.

Here are some details on each:

Cite Your Sources

The best way to avoid plagiarism is to cite your sources, particularly when you paraphrase someone’s ideas.

How you cite will depend on the style guide you follow (e.g., APA, MLA, or your in-house style guide).

Here are some citation tips:

• Use quotation marks when using someone else’s content word-for-word
• Include a reference to the source when paraphrasing (e.g., “according to the New York Times”)
• Include an external link to the exact source you’re paraphrasing from

Check for Plagiarism During the Editing Stage

Check your content for plagiarism during the editing stage so you can find and fix instances of plagiarism before you publish your content.

Here are some examples of steps you can add to your editorial process:

• Create editorial guidelines that outline your plagiarism policies and share them with your writers and reviewers
• Define editing stages (e.g., first-round review, second-round review, etc.) and include an originality check in a specific stage
• Get multiple people involved in the editing process to increase your chances of identifying missing citations or poor paraphrasing

Have open communication with your creators, so you can address plagiarism issues directly. And resolve those issues quickly.

Vet Your Writers

If you outsource your content, thoroughly vet your content creators to increase the chances of receiving work that’s both original and high in quality.

Vet your creators by:

• Asking for writing samples and reviewing them
• Requesting references to confirm expertise in the topics the writers are covering
• Creating a writing test and requiring a passing grade to be a contributor

Use AI Tools Carefully

AI is great for speeding up content production, but you need to be aware of the risk that unedited AI content can lead to publishing the same content as another site.

Some best practices for using AI tools while ensuring originality include:

• Informing the AI tool on your brand voice, business, and product information to improve your text outputs
• Personalizing your content with stories, personal experiences, and strategic insights
• Treating the initial draft as more of an outline that needs to be built out

What to Do If Someone Plagiarizes Your Content

While you can’t control what other people publish, you can try to get plagiarized content removed by following these steps:

1. Reach out to the webmaster and request that the copied content be removed
2. If they don’t respond, contact the copycat’s host provider to request removal
3. If the content remains live, report the stolen content to Google

Create and Publish Original Content

Building originality into your content process can reduce the chances of SEO plagiarism issues.

For example, you can have editors add a human touch to AI-generated content and complete an originality check using a tool like SEO Writing Assistant.
