However, since DKI increases your CTR (and hopefully your earnings), it often makes sense to use it–despite the small penalty it has on QS." Yes, it invariably does so use with some caution! Cheers, Dave. As a suggestion, do a google search with your query - tonnes of articles!
B.S. Why would making your ad MORE relevant hurt your qs? Maybe he's referring to using DKI when using misspellings or bidding on domain names, but in cases where it's a real word that will show, there's no way it hurts your qs. That is just plain wrong.
WTF??? where did perry get that information... that is the biggest crock of crap I have ever heard, that is completely wrong and there is no negative to using KDI. Please Dont quote perry marshall as a source of reliable information... please only quote google help files Information like this circulating can end up hurting lots of accounts and give out the wrong information online
Robert is right, WTF?!? Well-written keyword insertion ads in well-organized ad groups can make your ads more relevant to users when you use a more general ad with large numbers of keywords. These ads are more likely to receive clicks than a generic ad would for the same ad group. In these cases, keyword insertion may help improve the Quality Scores for your ads and keywords over time through improved clickthrough rates (CTRs) and overall performance.

I always run both regular ads and dynamic ins ads at the same time for testing purposes - especially in the early stages of a campaign. It helps lower your min bids to have the keyword in the headline, but I don't think Google can detect that with DI. After a few weeks, if the DI ads are performing well and your QS is great - then drop the regular ads and start testing DI ads against each other.
