Google analytics landing page tracking problem

[LauraM001]

I have noticed when looking at my landing page reports in GA that there are pages appearing that I wouldn't expect to see there.

I have set up a custom segment to show me only non paid search visits to the site.

The pages in question don't appear when doing a site: search in Google. And they redirect to a login page for non logged in users anyway.

Can anyone help shed any light on why this might be happening?

Thanks in advance.

Are these pages being linked from somewhere else other than Google?

No, not that I can discern anyway.

I'd want to double-check that. Take a look at your server logs to see if you can define the source of the incoming user or bot.
