Hi @SDelazz ,
The URL length would not decide if a dimension value is to be bucketed under the 'Low-traffic' but the number of unique values falling under that dimension (here, page?).
Also, low traffic bucket is something that can't be rolled back, therefore, you are encouraged to use Data Warehouse to run the reports.
The resolution moving ahead:
1. Up the 'Unique limit' for the dimension by raising a support ticket to Adobe Analytics team. (Any increase made to the threshold of dimension (here, page?), would come to action only in the next month - be prepared)
2. Leverage Data Warehouse (Low-traffic messiah)
3. Alternatively, you can define a unique page name for combinations of URLs. At the same time, use another dimension to capture the query string. Low cardinality can makes life easier in dealing with the dreaded Low-traffic. (Smart Implementation)
