I am very new to Adwords. In fact, I had not even heard the term 6 months ago. Now I am in charge of (and started) my company's Adwords campaign. We have been on line June the beginning of June. For June and July we had mediocre success. The at the end of July I made some tweaks and my statistics started climbing rapidly. We aren't doing huge business, but we are definitely generating more leads that we were before the campaign. On Wednesday of this week, it suddenly stopped. My CTR is going down, my placement is also and my conversions have plummeted. Has anyone seen anything like this?
This will depend on MANY things. You need to check your CTR, your quality score and your competition. Have a read of my article on Quality Score Also, take a look how your ads appear in different countries Finally, have a read of CustartMites AdWords Guide and tweak the hell out of your campaigns.
Had the competition increased?., what is the quality score that the keywords are showing? , Are the keywords grouped based on the theme>?
