Frequently asked questions
Do URL inspection tools run page scripts?
No. URL inspection uses static HTML analysis only. Remote scripts are never executed, and only the initial HTML response is analysed.
Can SEO tools inspect private pages?
No. They are designed for public URLs and will block private or unsafe network targets.
