I have a couple of questions which I could not find an answer to on the Web.
1. What files will search engines follow? I have seen Google descending into
text files, files without any extension and even C files.
2. Will a site get penalised for links to images that do not exist or for
broken images? What about files as in the above? Data files that no longer
exist... should they be mended/removed for the sake of SEO?
Thanks in advance,
