Im sure a lot of this has been covered all over this board .. but here goes: I havent been working with Adwords for a couple of year but just started about 24 hours ago. Started a campaign with a couple of groups - 1 group/ad pointing to the home page for keywords very specific to the landing page and the sites overall theme. 2nd group pointing to an internal page - but again very relevant to the ad and keywords. Minimum bid was fifteen cents on all kw and ads. All of these ran for what seems like approx 24 hours. Then as Im adding more keywords and ads today for more internal pages ... all of the min bids more than doubled. All ads turned off except one that I had already increased because of its relevancy. Here is the CTR I got over the 24 hours --> 2.19%.. googles cpm on this was $3.40 .. What did the algo not like about my ads ? Bounce Rate? CTR and CPM too low? Sheesh .. what to do?
two years earlier, the concept of QS was obsolete. Welcome to the new adwords. Its tougher, its expensive, and it will blow your mind (gosh. im sleepy) Your ctr is very good. You shouldn't be disappointed in that. optimize your landing page for select kw's and add them to one group. Don't use all your keywords in a single group. Diversify them
Your CTR is good although, for me, I aim for at least 5% CTR. Don't put too many keywords in one ad campaign.
try using adwords editor keyword grouping tool and group your KWs for more relevancy, then make your landing pages for them more relevant
