Google has announced that they are now going to be indexing SVG documents and files. SVG (Scalable Vector Graphics) is an XML-based graphics format specifically for vector graphic, both dynamic and static and graphics can be made and edited in any text editor since they are XML files.
You can, however, block your SVG files from being indexed by using the Robots Exclusion Protocol.
Their Webmaster Blog says: “We index SVG content whether it is in a standalone file or embedded directly in HTML. The web is big, so it may take some time before we crawl and index most SVG files, but as of today you may start seeing them in your search results.
