The website will be able to upload many different types of files, such as .pdf, .doc, .xls, .ppt., .jpg, .png, .gif, etc.  These files not only appear in their original form on the website, but they also are searchable by the search engines – which means that a search engine can “crawl” through the document and “read” the content to make that page on the website show up in searches.  These documents can also be downloaded by website visitors and saved to their individual computers.  All files can be search engine optimized (titles, descriptions & keywords).
