Ad showing for keyword not in my ad group

does anybody know whats going on?

[AlchemyV]

When I do a search in Google for Antigua Property, my ad appears in sponsored search

www.google.co.uk/search?hl=en&q=antigua+property&btnG=Search&meta=

yet, i cannot find a reason why it would appear as i have inspected all the keywords in all my adgroups.

Has anybody else experienced this?

use the ad diagnostic tool within your adwords account to see what it says.

It may be due to "broad" match of one of your keywords.

What type of match type you have set for your keywords?
