Question

What are the reasons for ‘Below First Page Bid’ errors in Google Ads, and how can I optimize bids programmatically?

Answer 1

Reasons for "Below First Page Bid" Errors

1. Low Max CPC Bid

Your bid is simply below what Google estimates is needed to appear on the first page for the selected keyword.

2. Low Quality Score

Even with a decent bid, a poor Quality Score (which includes CTR, ad relevance, and landing page experience) may force a higher bid to reach the first page.

3. High Competition

If competitors are bidding aggressively on the same keywords, the first page threshold rises.

4. Ad Rank Thresholds

Google calculates Ad Rank as Bid × Quality Score. If this value is too low, your ad won't qualify for prominent positions.

How to Optimize Bids Programmatically (Google Ads Scripts or API)

A. Using Google Ads Scripts

Here’s a sample script to raise your bids to meet the estimated first page bid:

javascript

function main() { 

const keywords = AdsApp.keywords() 

.withCondition("Status = ENABLED") 

.withCondition("AdGroupStatus = ENABLED") 

.withCondition("CampaignStatus = ENABLED") 

.get(); 

while (keywords.hasNext()) { 

const keyword = keywords.next(); 

const stats = keyword.getStatsFor("LAST_7_DAYS"); 

const firstPageCpc = keyword.getFirstPageCpc(); 

const currentCpc = keyword.bidding().

getCpc(); 

if (currentCpc < firstPageCpc) { 

keyword.bidding().setCpc(firstPageCpc); 

Logger.log( "Updated CPC for keyword '" + keyword.getText() + "' from " + currentCpc + " to " + firstPageCpc ); 

} 

} 

}

What it does:

• Loops through enabled keywords

• Compares current CPC with the estimated first page CPC

• Increases the CPC if needed

B. With Google Ads API

If you're using the API (v14+), you can:

• Fetch keyword-level metrics (e.g., metrics.estimated_first_page_cpc_micros)

• Adjust ad_group_criterion.cpc_bid_micros accordingly

Example API logic:

• Use SearchStream to get metrics.estimated_first_page_cpc_micros

• Compare with current cpc_bid_micros

• Use mutate operation to update bid if below threshold

Pro Optimization Tips

1. Add Bid Cap: Always set a ceiling to prevent overbidding.

2. Exclude Low-Quality Keywords: Improve Quality Score instead of just raising bids.

3. Segment High-Intent Keywords: Focus programmatic bid increases only on converting terms.

4. Use Bid Adjustments: Increase only for top-performing locations/devices/times.
