I have a pdf file at
Website.com/file.pdf （which is a url with a top google search ranking for my keywords)
I added more content to the pdf since it’s outdated. Can I simply replace the file via FTP with the new one and keeping the name the same so that the same URL is maintained? Would this prevent search-ranking for website.com/pdf from being affected?
I can’t seem to find information on this, although I’d have thought it doesn’t affect search ranking as long as the url is kept the same. Is this the same as updating a website page?
