Perguntas frequentes

How do I check my content score and the quality of my content?

To check your content score log in to Originality.ai. Then, select Content Quality Score and scan. After scanning you’ll see a high, good, or low quality score that evaluates your content. This provides an idea of how your content is likely to be perceived by an editor, teacher, or reviewed.

How to score content for marketing efforts?

Checking content quality scores for marketing efforts is an excellent way to review blogs and articles before publishing. Google and readers both appreciate high-quality content. Reviewing content scores can help your marketing team stay aligned with creating the people-first content that Google values.

Are content quality scores available in the API or in Bulk Scan?

Not yet. If this is a feature you would like to see in the future, let our team know!

Does a low, good, or high score match with a specific grade?

Originality.ai Content Quality Scores offer a probability of whether an essay or paper is likely to be perceived as low, good, or high quality by a teacher. The content score is a probability so it doesn’t equal a specific grade. Instead, use the content score as a measure of whether you’re on the right track with your assignment or whether it needs further refinement.

Does the Content Quality Score check for AI content or plagiarism?

No, the Originality.ai Content Quality Score does not check for AI or plagiarism. However, with Originality.ai it’s easy to scan for content quality, AI writing, and plagiarism in one scan within the app. Simply select all the scan types you’d like to run and click Scan!
