Can some one give me an advise about these? Because, ok, I can change my ads, delate my keyworks... and in english more or less... But, I have other markets, and I don´t speak those languages, only one time some one give me the translation, and this is a real problem.
Any advice is wellcome.
For example if you are selling widgets, cogs and sprockets you should have an adgroup for each of those keywords with ad copy that pertains to each KW, not lumping them all together.
Try also using the brackets, quotes negative KW to give you more targeted results. That way your ad for widgets won't show up for free widgets or info about widgets.
If you can't separate them out or you don't want to use the KW matching options, than there is not much you can do to fix the CTR and you must either pay the $5 or remove them completely.
So if you had 100 ads and each had ten searches and no clicks you would get your first strike and you'd have had hardly any exposure to Google.
If you've written a good ad, and have the right keywords you will not be getting 0.5% or anywhere near to it, relevancy is important and by having that low a CTR Google are actually saying that "our users are not wanting to see what you are offering" and it can't be anything to do with your site, as they haven't seen it at that time.
So everytime I search for 'car leasing', 'vehicle hiring' or 'problem with Ford motor car', their advert appears. If they sell BMW cars, I'm not going to click if I search for any of the above.
One trick is negative keywords, adding -leasing,-problem,-hire,-lease,-hiring etc... to the keyword list will help stop this.
Even better is to target exact phrases, but this is a bit restrictive.
Good question about the target country and campaigns... I really don't know. Technically, the ad for a keyword can only be in one adgroup at a time. If the KW is in two adgroups, then the two ads are rotated and never appear together. But if the two campaigns are targeted at two different countries then the ad wouldn't appear in the same place twice anyway, so technically it would work. You should try it. Perhaps one of your keywords/adgroups performs better in the UK than in the US or vice versa. It would also allow you to tweak copy for each country.
