I created an rss.xml file where I add my latest news and links to them so people can subscribe to my site's updates. The question is: do I have to add manually all the time latest news to my rss.xml file and upload it to the server? Is there any automatic way to deliver hot news to the rss feed? Is there any way at all that allows people to subscribe to my news but without my necessity to update and upload any files additionally?
There are plenty of ways to have it update automatically. You can buy tools or use a CMS. You can also use php or a similar language to generate it automatically if the content is in a DB. The RSS file could have a PHP or ASPX extension without a problem. Best of luck.
