I have some audio assets directories on my website. The server allows directory listing. i.e. all audio files will be listed if the user visited example.com/assets/audio/nature/. I don't want to change any server's configurations, so, I will place an index.html inside every assets audio directory to prevent listing.
I worry about the any SEO negative effect of that. The index file code is very simple as below:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<meta name="robots" content="noindex, nofollow">
<title>No Index</title>
</head>
<body>
<h1>
<a href="/" style="color:green;">Home Page</a>
</h1>
</body>
</html>
Does the meta tag robots in the above snippet enough to prevent any SEO issues?
