The estimated first page bid (Est. first page bid) amount approximates the cost-per-click (CPC) bid needed for your ad to reach the first page of Google search results when a search query exactly matches your keyword. This estimate is based on the Quality Score and current advertiser competition for that keyword
If your first page bid estimate is very high, it may mean that your keyword's Quality Score is poor. You can click the help bubble
next to your keyword to find details about the keyword's Quality Score (note that you can customize your columns to always show Quality Score). You can also check out a
list of optimization tips that can help you improve your Quality Scores and lower your costs.
The first page bid estimate is a guide, meant to give you greater insight with which to plan your bidding strategy -- but meeting your first page bid estimate isn’t a guarantee of ad position. Ad position will still depend on Quality Score, your CPC bid, your budget and account settings, and user and advertiser behavior.
