If you're applying steadily and getting silence, the problem is one specific stage. Find it before you do more of everything.
Walk your funnel:
Sourced to Submitted. If you're submitting almost everything you source, your targeting is too broad. Tighten it.
Submitted to First round. This is the resume-and-channel stage. Low conversion here usually means one of two things: you're applying through aggregators (switch to direct portals), or your resume isn't signalling relevance fast enough (tailor the top third to each JD). This is where most "no interviews" searches break.
First round to Second round. If you get first rounds but they stall, it's interview performance or story, not the resume. Build six STAR stories and a tight 60-second pitch.
Second round to Offer. Stalls here are usually closing and fit signalling, not qualification.
The mistake is treating "no interviews" as a single problem and responding with more volume. It's a stage problem. Each stage has its own fix.
Pull your last 40 applications. Find the stage with the biggest drop. Fix that one thing. Same effort, more interviews.
