Does low CTR always mean a bad keyword?

No. Some keywords are intentionally exploratory or upper-funnel. Use this script as a prioritization layer, then review intent and business context before making changes.

Can this script send alerts automatically?

Yes. Set SEND_EMAIL_ALERTS to true and add ALERT_EMAIL. The script can send a concise table of top low-CTR keywords after each run.

Can this improve quality score outcomes?

Indirectly yes. Fixing weak ad relevance and expected CTR patterns can improve quality score signals over time, especially on high-volume non-brand terms.

Should I pause all flagged keywords immediately?

Not by default. First test ad copy and intent alignment, then decide whether to restructure, narrow match type, or pause terms that remain inefficient.

За този script

Keyword Low-CTR Check is a production-ready hygiene script for identifying active keywords that attract impressions but fail to win clicks. It helps PPC teams target relevance work where CTR underperformance is most likely suppressing efficiency.

The script applies practical filters such as minimum impressions and minimum clicks, then computes CTR and ranks low-performing keywords by a simple impact score. This creates an actionable queue instead of a raw dump of data.

You can also enable optional email summaries for recurring monitoring. Used consistently, this script supports stronger ad-to-keyword alignment, better query intent matching, and healthier quality-signal inputs over time.

Implementation notes

Configure LOOKBACK_DAYS, MIN_IMPRESSIONS, MIN_CLICKS, and MAX_CTR_PERCENT based on account scale.
Run manually once and review logs to calibrate thresholds and output size.
Optionally enable SEND_EMAIL_ALERTS and set ALERT_EMAIL for automated digests.
Prioritize top rows by impact score, then improve ad copy, message match, and ad group structure.
Re-run weekly and track whether flagged keyword count and average CTR improve.
