What does 'view by post' mean?

Although I haven't reached the magic 50 post mark yet I was reading through the Adsense details and it says you've got a 50% chance of getting the 'hit' if someone views a thread you've started - or if it's viewed by post.

Viewing by thread I understand, that's the default way. But how can you view 'by post'?

 

Here you go:

I'd say it would be if someone searches your previous posts and clicks on one or another similar scenario.

 

Posts each have a permalink (top right where the post number is) - if someone views your post by permalink your ads will be displayed 50% of the time.

 

Thanks for the replies. But why bother clicking on the link when you can see the post already? Am I missing something?

 

If it's a particularly long and informative post, like that at the top of a sticky thread, some people will just link to the post instead of the thread. Personal preference I guess.

 

it's also used a lot in the forums to show posts, as it saves people have to scroll through 20 posts in a thread to see the one you wanted to point out.

 

In my case. I've earned about $1.5 so far....since I entered my ID in January...
