A 15-minute teardown catches most of what's actually costing an agency leads: a homepage that describes the category instead of persuading, real proof buried below the fold, and too many competing calls to action for any one to win. Run it in order, minute by minute, before touching a redesign.
Minute 1: The Three-Second Test
Load the homepage and look away, then look back. What's the first thing that actually registers, not what you know is on the page because you wrote it, what an unfamiliar visitor's eye catches first. If it's a hero image with no clear headline, or a headline that describes the agency category instead of what makes this one worth a call, that's the first thing to fix.
Minutes 2-5: Does It Answer the Four Questions
Scroll the whole homepage once, fast, the way a founder actually would. By the bottom, has the page answered: does this agency fit how we work, have they done this before for someone like us, can they move fast enough, and will this make us more money. Most sites answer zero to one of these clearly. Two is good. Three or four in the first screen is rare, and it's the difference between a site that converts and one that doesn't.
Minutes 5-8: Trust Before the Ask
Where does real proof show up, relative to where the first CTA shows up. If a "Book a Call" button appears before any specific evidence, that's asking for trust before earning it. Real proof beats vague proof every time: a specific result beats "we've helped dozens of brands," a named example beats a logo wall with no context attached to any of them.
A founder isn't comparing your agency on a checklist. They're deciding whether they trust you, usually before they've read past the first screen.
Minutes 8-11: One Clear Next Step, or Five Competing Ones
Count the calls to action on the homepage. A nav CTA, a hero CTA, a mid-page CTA, a footer CTA, a chat widget, a newsletter popup, they're not all pointing at the same next step, and when they compete, none of them win. The strongest agency sites repeat one clear action instead of offering five different ways to maybe get in touch.

This is the same teardown I run before any agency rebuild, applied to yours.
Minutes 11-15: Does It Feel Hand-Built or Assembled
This one's harder to name but easy to feel. Load speed, motion that's smooth instead of stuttering, text that's actually legible against its background, a layout that doesn't look identical to five other agencies running the same theme. None of that gets read consciously by a visitor. It gets read as a gut feeling about whether this agency pays attention to detail, before a single sentence of copy is evaluated.
What the Teardown Usually Finds
Almost never a redesign problem. Almost always a sequencing problem, the real proof is buried below a generic opening, the one clear action is competing with four others, and the site describes the agency instead of making the case for hiring it. Fix the order before you touch the visuals.
