- tjarratt 16y agoI'm not an expert, but I believe this to be correct - the contents of the canvas elements are created/managed by javascript, so they would likely appear empty to most spiders. Additionally, I don't believe there is any good way to crawl the contents of a canvas element - the best you can get from it is an image representation as a data uri, so no text or html elements with semantic meaning.
