I'm late to this thread but found it in researching a similar problem. I use designated targets to create a permanently-named internal HTML anchor that I can use in providing a precisely-targeted complete URL that points to a specific paragraph (as opposed to a section). Example: In the file index.org, the org-mode dedicated target <<ThisTarget>> should export to HTML as: http://www.example.com/index.html#ThisTarget. The name #ThisTarget needs to be permanent because the document in question is a work in progress.
Based on Nicolas's suggestion (downthread) about using #+HTML: or @@html: , I did a couple of quickie macros to create <a> anchors and links, but that's a pain and clutters up the on-screen display in org-mode.
