For arXiv submissions, please submit the abstract link; in this case: <a href="http://arxiv.org/abs/1410.5401" rel="nofollow">http://arxiv.org/abs/1410.5401</a><p>The advantage is immediate: One gets a plain website with the abstract, which allows the visitor to decide whether the PDF download is worth it. The PDF itself is only one more click away.<p>I personally would also leave out the v1, as that link automatically goes to the latest version in all cases.
