I ran Lodven on Lodven, a marketing diagnosis agent for founders Lodven, a marketing diagnosis agent for technical founders, was tested on its own website by its developer. The tool identified a lack of external evidence and citations as the sharpest finding, and prioritized a concrete experiment to address it, which is being run publicly. Lodven https://lodven.com is a marketing diagnosis agent for technical founders. You give it a URL and it tears the site down across nine dimensions: positioning and offer clarity, conversion and trust, SEO and crawlability, GEO whether AI answer engines can cite you , analytics readiness, and more. Then it hands you the top three experiments to run, each with a GitHub issue, a schema patch, and a GA4 spec. "Here's what to ship next," not a checklist of vague advice. The point is to close the loop most tools skip: find what's actually broken, run one experiment, measure, repeat. So I pointed it at lodven.com. The sharpest finding: almost no external evidence. GA4 referrals are basically my own tweets, Stripe checkout bounce-backs, and Google sign-ins. Nobody outside is writing about the product, which also means AI answer engines have nothing to cite when someone asks about site-diagnosis tools. The experiment it prioritized was unglamorous but concrete, and I'm running it in public along with everything else. That's the whole idea: the diagnoses, the experiments that work, and the ones that don't. If you pointed a diagnosis tool at your own site, what would it catch that you've been ignoring?
