Yes, this structure can be used to talk about the possibility that something happened in the past.
For example, you can say 'Expector may/might/could have missed my blog.' (You're not certain whether it was actually the case, though.)
'Could have' can also be used to say there was a possibility of something happening in the past, but it didn't happen. For example, 'I could have been killed.' (But in fact you weren't killed.)
It's such a useful structure - let's try to create a blog to practice it.
Sample paragraph
I wonder if Expector has missed my blog. As the blog mod here, he's supposed to read and even leave a comment on the blogs. Besides, he commented on every blog I wrote. So he might have missed my blog, or he may have read the blog, but failed to leave a comment or click on the 'Like'. He might have decided he wouldn't bother to leave a comment on every blog - only on the blogs which he thought derserved one. I could have tried to let him know when I published the blog - he could/would have commented on it if I had done so.
Bonus
I'll try to correct you if I spot a mistake in your blog - of course, if you really want to be corrected:)
Your turn...
