RSS is very easy to use as long as publisher provides feeds. When there is no feed available it gets tricky (but still possible) to get one. There are few ways to solve this problem so I decided to start with simplest and build complexity up in future posts.
Page2RSS is service that creates feeds with changes from any web page.
What it does
Interface for service is merely single input form where you put site address. Page submitted is going to be monitored for changes and all of them are going to be put in RSS feed you can subscribe to.
There is some internal threshold to changes so minor ones won’t be reported. Good aspect is unlike similar services it doesn’t rely on structured data. Any change is reported and there is no need to create specific rules to detect them.
Extra for publishers
Service also features web button generator that makes it easy to create embeddable code for its feeds. Not relevant when using CMS which usually provide native feeds, but for static site it may be really easy way to create feed that doesn’t need maintaining.
