SEOMagnifier is an online tool that claims to be the ‘best plagiarism detector.’
However, is SEOMagnifier a reliable way to check content for plagiarism?
In our in-depth SEOMagnifier review, we put SEOMagnifier’s Online Plagiarism Checker to the test with both published blogs and complex patchwork plagiarism samples.
Your actual results may vary, simply because, as our tests reveal, the tool was not consistent. See a quick overview as well as the full results in our SEOMagnifier review below.

SEOMagnifier is a suite of online tools, including a paraphrasing tool, online article generator (also known as a “spinner”), AI content creator, backlink generator, and more.
It offers a handful of tools for search engine optimization professionals, including tools to generate long tail keywords and similar services.
For search engine professionals who need to quickly rank a site in Google and other search engines, being able to research keywords, backlinks, and other options can help them work more quickly.
Additional tools like a plagiarism checker or grammar checker can help SEO experts to make sure the content they post is grammatically correct and not at risk of being copied from other sources.
SEOMagnifier is geared toward search engine professionals and anyone who needs to conduct search engine ranking-related activities like keyword or backlink research.
The plagiarism checker tool is free to use for up to 1,000 words. Other tools on the site also claim to be free. However, they may be limited in terms of how many words can be researched or how many times you can use the tool. There is no premium feature or upgrade available, and registration isn’t required.
The site also offers an article rewriter, AI content generator, paraphraser, grammar checker, backlink and keyword generator, and other tools focused around search engine optimization.
For this test, we focused specifically on SEOMagnifier’s plagiarism checker.
Step 1: We chose text samples from two blog posts directly from the Originality.ai blog:
Step 2: We then pasted the content directly into the Originality.ai plagiarism checker and into SEOMagnifier’s plagiarism checker and ran each tool, respectively.
Step 3: For the second part of the test, we chose examples of patchwork plagiarism, which is a more subtle example of plagiarism. This type of plagiarism is often harder for even advanced plagiarism checkers to detect.
Step 4: We then ran both samples through SEOMagnifier and the Originality.ai Plagiarism Checker to compare results.
Originality.ai Plagiarism Checker: 100% Match

SEOMagnifier: 0% Match (100% Unique)

Originality.ai Plagiarism Checker: 100% Match

SEOMagnifier: 0% Match (100% Unique)

Originality.ai Plagiarism Checker: 100% Match

SEOMagnifier: 0% Match (100% Unique)

Originality.ai Plagiarism Checker: 62% match

SEOMagnifier: 0% Match (100% Unique)


As you can see from the results above, SEOMagnifier failed to detect plagiarism on either of the existing blog posts or the patchwork plagiarism samples we pasted into it.
Beyond this, the completion percentage was also unreliable. It typically stalled at around 80%-83%, even after it provided the plagiarism scan results.
The key takeaway? Use the Originality.ai Plagiarism Checker if you’re looking for a more accurate, reliable plagiarism checker.
With high accuracy even on patchwork pieces pulled from various sources, Originality.ai provides you with quick, easy-to-understand results, as well as highlighting passages where plagiarism may be an issue.
It’s a top-rated plagiarism detector for teachers, students, SEO pros, and other content professionals.

In addition to pasting or typing your content directly into the form field, you can also upload .txt, .doc, .docx, .rtf, and .pdf files into the plagiarism checker. However, as with our tests, you may find that the SEOMagnifier completion scan score stalls before it reaches 100%.
The tool is free to use; however, given its lack of accuracy and reliability, we recommend using a more dependable alternative to SEOMagnifier, such as the Originality.ai plagiarism checker. In addition to its detailed plagiarism scanning functions, you can also take advantage of Originality.ai’s patented AI detection and much more, all in one place.
