ASA Web Site Citation
Web sites do not include subscription databases
"A general rule may be applied to the citing of websites: If the website contains data or evidence essential to a point being addressed in the manuscript, it should be formally cited with the URL and date of access." (ASA Style Guide pg. 87)
A date of access is used if there is no date of publication or date of revision on website. If no date can be located then use n.d. in place of the year and note a date of access.
Author's Last Name, First Name Middle Initial or Corporation sponsor. Year of update (use N.d. if no date is found). "Title of Content." Name of webpage. Accessed date. Complete URL.
