Where RELLO excels

Solar-specific acquisition strategy. RELLO understands the long sales cycle and high customer acquisition cost that make solar marketing fundamentally different from most trades. And their experience across residential, commercial, and community solar means they can adapt messaging for different buyer types — a homeowner evaluating rooftop panels thinks completely differently than a commercial building manager evaluating a PPA. That distinction matters in your campaigns.

And if you're a solar contractor specifically, that trade depth counts for something. RELLO knows the seasonal surges, the buyer hesitations, and the search patterns that generalist agencies miss entirely.

Where Fervor differs

RELLO and Fervor don't actually compete. RELLO gets more people to your site. SEO, PPC, paid channels. We focus on what happens after they land. So if you're pulling 2,000 visits a month but your phone only rings 9 times, that's not a traffic problem. That's a conversion problem. And conversion is the only thing we work on.

(Quick way to tell which problem you have: check your Google Analytics. If your monthly sessions are under 500, you probably need traffic. If they're over 1,000 and you're still not getting calls, you need conversion work.)

Revenue per visitor

Your traffic has a dollar value. But most agencies won't calculate it because the number isn't always flattering. We measure what each visitor is actually worth in booked revenue, then rank your fixes by which ones move that number fastest.

The Site Inspection

Before we recommend a single change, we score your site across 6 categories against 65 national contractor brands. You get a Fervor Grade™ and a ranked fix list. No sales call required. And no money changes hands.

Conversion-first design

Booked by Design™ doesn't start with a homepage mockup. It starts with conversion benchmarks from 18 trades we've already scored. So layout decisions, CTA placement, form position, the order your services appear on the page, even which photo goes above the fold — all of it is backed by what actually gets contractors booked.

Who should choose which

Choose RELLO if:

  • You need an agency that only works with solar contractors
  • You want solar-specific keyword strategy and campaign management
  • You value solar and renewable energy only — deep specialization across residential, commercial, community solar, and battery storage

Choose Fervor if:

  • Your site gets traffic but your close rate from web leads sits under 5%
  • You want to know exactly which pages are bleeding leads right now
  • You need a website rebuilt around revenue per visitor, not just how it looks
  • You want a Canada-based agency that works with US and Canadian contractors

One more thing. These aren't competing solutions. If your site converts well but needs more eyeballs, RELLO can drive that traffic. If you're getting the traffic but it's not turning into booked jobs, that's our side of the equation. And some contractors end up working with both.
