Don’t use hyphens, i.e. use ‘blue widgets’ not ‘blue-widgets’ as well. Why? Google treats a hyphen as a space so they are the same thing. If you have both in your account Google randomly picks which one to use – that’ll have all the impressions/clicks, the other will sit on zero. You want it to pick the none-hyphen one if using dynamic keyword insertion because then Google will display it as such and make the copy look more relevant – matching the majority of searches, hardly anyone searches with a hyphen.
For the first 2 weeks of the month I had a key phrase in one account – the none-hyphen one was picked and a CTR of 20% over 1000+ impressions. I was restructuring my accounts and moved it to another, same bid, same copy, the hyphen one got picked up and CTR only 7% or so for a similar no. of impressions.
However, when I test this I get weird results. Search for two keywords with and without hyphens brings different results, so I’m not 100% sure. But then searching for the same key phrase, waiting, then searching again brings different results too – Google seems to have some weird inconsistencies.
Still not sure whether to bin my hyphen keywords or not - anyone else have any ideas?
Cheers,
