What is a grammar checker?
The Grammar Checker scans your text for grammatical errors, spelling mistakes, punctuation issues, and common writing problems. It highlights errors with explanations and suggests corrections to help you produce polished, professional content.
Grammar quality directly impacts your site's perceived authority and trustworthiness. Google's quality rater guidelines note that poor grammar and spelling are indicators of low-quality content. Readers are less likely to share, link to, or return to content with obvious errors.
Why use a grammar checker?
Content with grammar errors loses reader trust, reduces dwell time, and signals low quality to both users and search engine quality evaluators. A grammar check before publishing is a simple quality gate that protects your content's credibility and indirectly supports your SEO performance.
Grammar errors don't directly trigger ranking penalties, but they affect content quality scores used by Google's quality raters. High error rates signal low-quality content, which can reduce your ability to rank for competitive terms.
What types of errors does this checker catch?
The checker catches spelling mistakes, grammatical agreement errors, punctuation issues, commonly confused words (affect/effect, there/their), and sentence structure problems.
Is this as good as Grammarly?
This is a built-in grammar checking tool optimised for SEO workflows. For comprehensive grammar checking across all your writing, dedicated tools like Grammarly offer more advanced capabilities.
Should I trust every grammar suggestion?
No. Grammar checkers can produce false positives, especially for technical jargon, brand names, and deliberate stylistic choices. Always use human judgment to evaluate each suggestion.
Can grammar checkers detect AI-generated content issues?
Standard grammar checkers don't specifically detect AI-generated content. However, AI writing often exhibits characteristic patterns (overly formal tone, repetitive phrases) that human editing should address.
