Q: What is the cut off point for keyword volume in terms of global monthly searches?
A: There is no strict rule regarding keyword volume. While large industries like insurance can use thousands of keywords in terms of volume in the Keyword tool, tightly concentrated industries may use small volumes of keywords.
Keyword volume may vary but what is important is keyword value. What is their value to you as well as your customers? In some cases, keywords have very low volume but they have more value. These are the keywords you should run.
