Thanks Carl, my main site gets quite good rankings for all the reasons you suggest. But Google doesn't appear to find/read the Blog.

Which is an item in my main navigation and in my site map.

So if I set up a Google Alert (which now includes Blog content) my Blog doesn't feature in the Google ...

I am a farmer with a web site and a Blog powered by Serendipity.
My current challenge is. How do I get Google to find my Blog ?

Last question, whats the best way to back up my Blog? I post images and text every day so currently have almost 500 images up there.

Any advice or guidance much ...
