If keyword is widget and the word widgetdreams is in the ad copy, does the widget part of widgetdreams get bolded...?
robsp is correct - but I just wanted to make one distinction, that you probably already know. But hey, I think I'll say it anyway, just in case. ;)
If the keyword is widget and the words widget dreams (i.e. as two words) is in the ad copy, then the widget part of widget dreams does get bolded.
