I'm no expert but it depends on your source file. If you did it from scratch in vectors, if you grabbed it off the 'net and it's not a real SVG, if you took a .png and converted it to SVG. I haven't had any issues yet with what I am getting off the web using filetype:svg in my Google searches. I do open the logos in Inkscape just to make sure they are real SVGs and not just bitmaps where the user just changed .png to .svg <-- that will not work.
