Google Can now Index SVG Files
First, what is SVG? SVG (Scalable Vector Graphics) is an open, XML-based format for vector graphics with support for interactive elements, developed and maintained by World Wide Web Consortium (W3C). Google recently announced that you can now see SVG files in Google search results. This means that Google can now index SVG contents whether it is in a standalone file or embedded directly in HTML.
To see it yourself try searching in Google search using queries “sitemap site:fastsvg.com” or “HideShow site:svg-whiz.com” (examples from http://googlewebmastercentral.blogspot.com/2010/08/google-now-indexes-svg.html)
If you wish to exclude SVG files from Google search results you can use “X-Robots-Tag: noindex” directive in the HTTP header which you can read in this article: http://googleblog.blogspot.com/2007/07/robots-exclusion-protocol-now-with-even.html.
