Dhiru's Notebook

Dhiru's Notebook is a business whose own site puts it this way: "👋 A Better HF SDR Than RTL-SDR?The idea is simple: build a low-cost, purpose-built HF receiver around a cheap high-speed ADC instead of repurposing an RTL-SDR." When AI engines look at it, they find little to work with. It scores 4.2 out of 10.

On its own pages the site does well on a clear heading structure, a clearly stated business identity, crawler access and the files AI engines look for and sitemaps and entity links AI can follow. It is passable on some structured data. What holds it back is credibility markers like credentials or reviews.

Off the page there is only faint evidence that the domain is only lightly established and there is little discussion of it. Beyond that, almost no other sites link to it, AI engines do not yet recognise it as a distinct business, there is no press coverage to draw on and it does not come up on Reddit. None of that can be fixed on the page: it has to be earned.
