I can say it's not that one, if it's that important to know - DataForSEO is our provider for every aspect at the moment.

I am confused.

I always thought keyword tools use both: backlink data and estimated search volumes.

For example ahrefs has, to the best of my knowledge, its own crawler for backlink data but mostly buys search volume estimates.

Does your tool offer search volume estimates at all and does it come from the same provider as the backlink data?

That just confirmed that you're using "the same backend provider."

Buy itself that's not bad. The problem is that if you're doing what everyone else is doing, then you're probably not realizing any efficiencies. That means your prices will eventually mirror everyone elses.
