May you put reference or source links as inline text only? Do you think clickable links are better? No, we would not talking about backlink tricks here. Left off the popularity dream first.
Inline vs clickable link
If you choose to put inline text for the reference URI/URL/link, they might not be usable. They are bad in Web usability. Users–in this case, human–must have to do some efforts to be able to use the link. Because they are not click ready. By using mouse, select the texts, copy, drag and drop into address bar to open the link. Or other ways similar like that. And also, the permanent link sometimes not descriptive enough. Not easy to use. Not usable.
For tabbing navigation users, they are not reachable. Tab keys may useful to navigate the content between headings, links (
a href element), inputs, buttons, objects, and textareas.
For screen reader users, they are not accessible. The
a href element will not work. Bad in Web accessibility. Normally, screen readers will read that element as “Link” followed by its anchor texts.
