Hi everyone. I am a relative newbie to SEO, but I have developed a web site for my company which uses PHP and a MySQL database. The PHP is necessary because it pulls live data from an outside source for our visitors. Because I use PHP, my server does not show a last modified date for the page.
My web site contains a database of descriptions of the various products we have available for sale. I have this in the database instead of on the actual page because it is easy for anyone to edit, and it makes it easy for me to look through the database and see what items need to be updated.
I have been considering using a line of PHP code to cause the server to show a last modified date that would be in line with when the item description was last edited. Would this be beneficial as far as the search engines, so they can see when pages are updated, or would they somehow see this as spam?
