Frequently Asked Questions
Common questions about on-page SEO and this tool.
On-page SEO refers to the practice of optimizing individual web pages to rank higher in search engines. It includes optimizing content, HTML source code, title tags, meta descriptions, headings, images, internal links, and structured data. Unlike off-page SEO (backlinks, social signals), on-page factors are entirely within your control.
The title tag is one of the strongest on-page ranking signals. It appears in search engine results as the clickable headline and in browser tabs. A well-crafted title between 30 and 60 characters that includes your target keyword can significantly improve your click-through rate and search rankings.
The score is calculated by evaluating 15+ on-page factors across content, technical, and social categories. Each check is rated as pass, warning, or fail. Passes contribute full points, warnings contribute half points, and fails contribute zero. The final score is a percentage out of 100.
Open Graph (OG) tags are meta tags that control how your page appears when shared on social media platforms like Facebook, LinkedIn, and X/Twitter. They define the title, description, image, and URL for the social preview card. Without them, platforms may pull incorrect or unflattering content from your page.
