I know. But with the switch the limit decreased from 300K Rows to 150K Units, aka 3000 rows.
Nothing 
Great. And directly a question:
"Organic Competitors" is only possible for one Website ? (one domain, 10 competitor domains)
Is it possible for a list of domains?
Example:
domain1 - competitorofdomain1
domain2 - competitorofdomain2
etc.
Only possible with a domain per request. But you could use a formula and only extract the first competitor for each domain.
