The top 29.5% of “dog” based keywords account for 80% of the total traffic (418969).


The top 34.8% of “personals” based keywords account for 80% of the total traffic (30106).


The top 37.4% of “blog” based keywords account for 80% of the total traffic (48092).


The top 49.3% of “buy” based keywords account for 80% of the total traffic (119031).
