We have forms on our site that we're using for lead generation. When submitted, the user is directed to the requested piece of content and the file begins downloading right away.
We track user behavior through our marketing automation software, and some people are downloading the file 4-5 times in a row, without realizing they've already gotten the file.
I think this is because, especially in Chrome, the download indicator at the bottom of the browser is quite subtle. Are there common patterns or suggested methods that might announce to the user that the file is currently downloading, or that the file has downloaded? Something that is less subtle?
