Is OneClickSEO On-Page SEO Checker 100% free?

Yes. OneClickSEO's browser extension is completely free to install and use, with no hidden fees, no trial limits, and no credit card required. It's built to give developers and marketers instant on-page audits without the cost of enterprise SaaS tools.

Does this extension collect or store my private browsing data?

No. OneClickSEO only analyzes the publicly visible content of the page you actively choose to audit when you click the icon. It does not track your browsing history or collect personal data in the background.

How often should I run an on-page SEO audit on my site?

For actively updated sites, run an audit every time you publish or significantly edit a page. For established pages, a monthly or quarterly audit helps catch issues like broken links, outdated meta descriptions, or new duplicate content problems before they impact rankings.

What is the difference between On-Page SEO and Off-Page SEO?

On-page SEO covers everything you control directly on your website — title tags, content, headings, images, internal links, and technical structure. Off-page SEO refers to external signals like backlinks from other websites, brand mentions, and social signals. Both work together, but on-page SEO is the foundation — without it, off-page efforts have a weaker foundation to build on.
