Simple question about Google SEO.

Let’s say I have a blog entry on my website called “A”. Let’s say no other sites link to this entry b/c it’s boring, but many other sites link to OTHER entries on my blog, b/c they are interesting.

Now, when someone does a Google search for terms contained in entry “A”, will this page have a decent Google rank b/c it’s on a blog that is very popular and has been linked to often? Or will it have a very low rank b/c no one links to that specific entry “A” at all?

Also, can someone suggest an SEO forum where a question like this is most appropriate?
