1. Why can’t I cluster keywords?
a. Firstly, you should crawl the SERP for target keywords before clustering keywords with the SERP.
you can easily check this by viewing the top-left corner of the program:
b. Try to decrease the parameters used for the keyword clustering
If the QPM(Query Per Month) of your keywords are 0 or below 10, you need to set the Minimum Group QPM to 0.
Likewise, you can improve the situation by decreasing the “Minimum Similarity for Classified Groups” (this value is usually set to 60.00% by default).
c. If you have tried the methods above, and all have failed, please try to update the program or contact us.
