Frequently Asked Questions
What does a content grader check?▼
A content grader usually checks on-page basics like headings, keyword usage, readability, structure, and whether the page matches what searchers expect. Some tools also point out missing subtopics and clarity issues.
Is there a free SEO grader?▼
Yes. Many tools offer free checks, but some hide useful results behind trials. WordCount AI offers a free trial so you can run real grades before deciding whether to upgrade.
Which content grader is most accurate?▼
