creating feed from web site without feed

Hi,

I use rss-multiimporter, is there a way that I can create the feeds myself? Some sites do not have rss – and that creates great challenges for me – I have very limited skills within WP – I have looked at feed43 but is currently not working.

Kind regards,

A
