I used one of those free xml site map generators freely available on the internet to generate a site map of my website. I then uploaded this to my web server and submitted the site map on Google Webmaster Tools. The problem with this is that I will need to keep re-generating, uploading and re-submitting the site map every time the site changes.
I wondered if anyone could tell me if there is a way to have the site map update automatically when the site changes so that it's less time-consuming and more efficient? The site is built on the Magento platform so uses PHP as the base language.
