Indexed or not..

Hey,

im a little bit confused about that whole "indexed or not" thing. Maybe u can tell me if i'm right or totally on the wrong path.

Presumption a) If a page has been crawled by google and at that time my link was on it, will this link defintely be indexed?

Presumption b) If a link is indexed, it must show up when i do a reverse search for backlinks with a specific program?

Hope I filtered out the right info and having the right conclusion. I guess the pros can answer this with ease

Best Regards

Answers:

A. Yes it will if the link does not have the rel="nofollow" attribute in the "A" tag.
B. Links don't show up immediately on search engines sometimes it can take some hours or days.
