RobotsGuard
    SEO infrastructure insurance

    Catch SEO disasters before they wipe out your traffic.

    A stray Disallow, a forgotten noindex, a canonical pointing to staging, and your traffic, revenue, and pipeline disappear before anyone notices. These are the disasters real teams shipped to production.

    Meta Robots

    A WordPress plugin silently noindexed every blog post.

    The most invisible noindex of all: in the headers.

    A CDN config added X-Robots-Tag: noindex to every response. Invisible in HTML, fatal for indexing.

    Canonical

    12,000 pages stuck in a canonical loop.

    A migration created circular canonicals (A → B → C → A). Google ignored every signal and rankings collapsed.
