> Should be great lead-gen, but I've not found a way to convert those visits into downloads/sales of my own plugins
Ah I see. You've got some general advice content and people write to you about it. Since you obviously tracked conversion for that, I see these options:
a) Answer those emails sincerely as a hobby
b) Answer with a template only ("Please write to the creator of that plugin you found, they'd love to help you!")
c) Explain somewhere in the article that you can only provide email support for paying customers, then don't answer
d) Put in the article: "If you need help installing a plugin other than $MY_PLUGIN_NAME, I'm happy to provide support for you for $15 per 15 minutes. Buy customer support now"
