The OG title is descriptive and keyword-rich, which helps with search and social discovery: BPMKeyFinder – Accurate Song BPM & Key Analyzer for DJs and Producers. The description does a solid job of explaining what the product does in-browser, mentioning tempo, key, Camelot code, and the privacy aspect powered by Essentia.js. That said, there’s a critical missing asset: the image. The image is not accessible, which means any social post will render as text-only and fail to capture attention. Without a visual, click-through will almost certainly suffer. The data also omits typical social defaults like og:type, og:url, and a Twitter card tag, which can hurt consistency across platforms. The current copy is informative but a bit long for social previews and could be tightened to ensure a punchy, scannable preview that matches the page’s hero language.
In short, the prose is solid and credibility-focused, but the absence of a usable image and the lack of standard OG tags will blunt performance when shared.
