I have new contents to add and update a current site.
As of now, everything is under www.example.com/1stdirectory/content.html.
Since there are so much information, I think it is best to create new .html pages and organize it, rather than adding everything unto that one .html page.


In order to make the site SEO as possible, should I create a 2nd directory and create new html for the new contents?
http://www.example.com/1stdirectory/...ctory/new.html
http://www.example.com/1stdirectory/...ctory/yay.html


Thank you in advance.

No, everything should be in the same directory. Multiple directories are necessary for very large sites that cover a lot of different topics or run multiple back-end scripts. It is actually silly to create a new directory for each and every HTML page ... from both a practical standpoint and an SEO standpoint.

Alternative is to not create the 2nd directory but to add new pages like
www.example.com/1stdirectory/newcontent.html
www.example.com/1stdirectory/morecontent.html
www.example.com/1stdirectory/helpcontent.html

and etc.


Wonder which method is best and most recommended.

Yeah, all the .html pages will be on the same directory but I like to know if I should all have it under the 1st directory or have one more directory (2nd directory) and have the pages for organization.

Multiple pages, one directory. Or no directory at all. www.example.com/page.html
