Apparently I have to request an exception. I can't even think of a company that has a 'crown' as a trade mark (apart from a UK paint company).
How long before other pretty standard words become exceptions? What other words have been flagged for exceptions? How long does the exception request take (I couldn't be bother to find out)? Can I request a word to become an exception?
I think 'aff' should be an exception word (think about it!)
BTW- The oddest thing was the advert was in Dutch.....
Approval came within a few hours, and I could add new ad groups within the same campaign without requesting a new exception. For a new campaign the system wanted a new exception request, though (which again was approved within a few hours).
However, I haven't seen this restriction applied to product names - as per "Crown Lager" in Australia .
As for the "greenwidget" situation, I think Google should display it as a warning that you have to click through, and not an exception request. I have a couple of words in my niche that fell into this category (but were approved).
For initial cap conjoint words, e.g. "GreenWidget", they should be allowed, as they are more likely to be brands than a spacing error.
