Ramp up is a separable phrasal verb, and knowing exactly how far that separability extends is one of the more consistently tested grammar points around this word.
With a noun object, both placements are grammatical -- "ramp up testing" and "ramp testing up" are equally correct, with the object-first order often more natural for long objects. With a pronoun object, only one placement works: the pronoun must sit between the verb and the particle -- "ramp it up," never "ramp up it."
Noun objects: a real choice, not an error
Because "ramp up" is separable, a noun object can go either right after "ramp up" or between "ramp" and "up." Neither order is an error.
"We need to ramp up testing before the release. / We need to ramp testing up before the release."
Both are correct. Placing the object before the particle is simply the more natural default when the object is long or complex.
"Management wants us to ramp the new hires up faster than the standard schedule."
A shorter, self-contained object like "the new hires" reads comfortably split between "ramp" and "up"; a much longer phrase ("ramp up our customer support capacity ahead of the launch") reads more naturally kept together after the particle, simply because splitting a long phrase in the middle gets harder to parse.
Pronoun objects: no exceptions
Pronouns behave differently. English phrasal verbs require a pronoun object to sit between the verb and the particle, and "ramp up" is no exception.

"Ramp it up" and "ramp them up" are correct. "Ramp up it" or "ramp up them" are simply wrong -- not less natural, not a stylistic choice, just ungrammatical.
The rule to actually apply
Don't mark noun-object splitting ("ramp testing up") as an error -- it's a stylistic default, not a rule. Do mark pronoun-object splitting ("ramp up it") as an error -- that's the one placement rule with no exceptions. Getting this distinction right is what separates someone who's memorized one correct sentence from someone who actually understands how the phrasal verb behaves.
Why the pronoun rule feels stricter than it looks
Most advanced learners already apply this pronoun-placement rule correctly with more familiar phrasal verbs -- nobody says "turn off it" instead of "turn it off" -- but the rule can feel less automatic with a two-word phrase like "ramp up" that reads, at a glance, more like a fixed unit than "turn off" does. Treating "ramp up" the same way you'd treat any other separable phrasal verb, rather than as a special fixed phrase, is the fastest way to make the pronoun placement rule feel automatic instead of like a rule you have to consciously apply every time.
Practice scenarios
Practice using ramp up in situations like:
- choosing between "ramp up X" and "ramp X up" for a long versus short noun object
- catching a pronoun-placement error like "ramp up it" before it goes out
- explaining to a colleague why one order is a style choice and the other is a hard rule
Useful practice phrases:
- "We need to ramp up testing before the release."
- "Management wants us to ramp the new hires up faster."
- "Let's ramp it up starting Monday."
One placement rule is a style choice; the other has no exceptions.
Know which is which, and you'll never second-guess a pronoun again.
