Ask me about any domain — I'll look up backlinks, authority scores, tech stack, and more using the RankParse API.

— Why nowThe web is full of AI noise. Backlinks are the signal Google still trusts. When any page can be written by a bot in seconds, content alone can't be ranked. What hasn't changed is who chose to link to whom — that's still the strongest authority signal on the web.
