If you've already set up Dynamic Re-Ranking (DRR), but you're not seeing any impacts or getting "Low Re-Ranking Effect" and/or "Click & Conversion" warning in the Re-Ranking dashboard, it's possibly because:
1. Your Analytics is not receiving enough search traffic
2. You are not getting enough valid click and conversion events on a record for a given query
Please note that DRR re-ranks per query. It requires 20 clicks or two conversion events per record per query in the last 30 days. This means, for a record to be re-ranked for a given query it must have a minimum of 20 clicks or 2 conversion events for that query.
We have found that this usually takes about 20K click and conversion events in the last 30 days, but this can vary depending on the size of your business.
