I started an Adwords campaign 3 days ago Everything was working great and I noticed I was the only advertiser for a certain keyword phrase. The first 2 days I had a quality score of 7/10 on this keyword and a CPC of $0.10. My max bid was $0.25. All of the sudden, I only got 1 click today my Quality score dropped to 4/10 and my ads aren't showing because it says my bid is too low. I swear, there were no ads for this keyword for weeks before my campaign started (I was checking)...My CTR the first 2 days was around 4%. Do I just need to up my max bid? Help!
Are you doing broad match or exact match for your keyword string? Adwords quality score is factored on a variety of metrics. Make sure your ad copy is relevant to your keywords, look into which network is affecting your quality score (Google's search network or Google's content network). Make sure your landing page offers what your ad copy is promising.
