Inside Numbar
The NUMBAR algorithm was developed by our team of scientists and uses more than 14 distinct information segments to assess 5 key quality areas to calculate the quality score of a particular number.
Numbers tracked over a longer period with more records deliver more consistent performance. Recently added numbers may perform well, but are not rewarded as hansomly as consistent performance over a prolonged window. Numbers dialled recently offer a fresh view on their performance and are deemed more valuable than numbers with limited recent activity. Numbers with high RPC and/or high success ratios over several performance windows are deemed more valuable.
Consistency
5 Calls per month for 12 months are better than 50 calls in one month.
Recent activity
20 Calls in the last 3 months is better than 20 calls 3 months ago.
High Volume
Numbers called 20 times deliver more accurate results than numbers dialled once only.
Right Party Contact
Considering all of the above, high contact ratios with the right person is rewarded.
Success Ratio
Considering all of the above, high successful call ratios are rewarded.
