Speed

What Lighthouse actually sees.

Below is the median of 12 mobile audits per platform, on representative Irvine service-business templates. Performance is the only score that gates Google Search results. Builder stacks ship with editor JS that never goes away.

Score by platform

Median of 12 audits per platform, mobile profile, throttled to fast 3G. Custom builds clear 90 on every metric; builder stacks bottleneck on Performance.

Core Web Vitals

How far each metric clears Google's pass bar.

Core Web Vitals are now an explicit ranking signal. The bar isn't a perfect score — it's passing. Custom Next.js builds clear it on every axis. Builder stacks fall short on TTFB and LCP, the two metrics that matter most for ad landing pages.

Custom Next.jsBuilder average

Outer ring = "Good" threshold from Chrome UX Report. Custom builds sit on or outside the ring on every axis; builder averages stall on TTFB and LCP.

Control

The feature matrix that decides who ranks.

Speed is one input. The other is how much control your platform gives you over the things Google actually reads — schema, meta, internal linking, canonical URLs. Here's the head-to-head on a fresh template install.

The bill

What you actually pay over 36 months.

Total cost of ownership isn't the sticker price — it's fees + plugins + designer fixes + lost conversions from a slow site. Priced at the typical Irvine home-services lead value of $42, here's what the next 3 years look like.
3-year total cost of ownership

What you actually pay over 36 months

Platform feesApps & pluginsDesigner fixesLost-conversion drag

Includes platform + apps + designer fixes + estimated lost conversions from slow sites (priced at avg Irvine home-services lead value of $42). Custom builds pay back around month 14.

The custom build is the cheapest of the four after month 14. The lost-conversion stack on Wix and Squarespace dwarfs everything else — slow sites are quietly the most expensive line item in your marketing budget. We see this every month in Orange County: an HVAC operator running $4K of Google Ads to a Wix landing page is paying twice for every click that bounces.

SEO control

How much steering wheel you actually get.

Every platform claims to be “SEO friendly.” What that means in practice — schema control, edge caching, robots tuning — varies wildly. Here's what's exposed to you on a fresh template, before you pay for premium plugins.

Decision matrix

So which one is right for you?

Not every Irvine service business needs a custom build. Here's the honest read on when each platform makes sense.

Choose Wix if…

  • You're testing an idea this quarter, not building for 5+ years.
  • Your customers will never compare you to a custom-built competitor.
  • You need to edit everything yourself with zero help.

Choose Squarespace if…

  • Brand aesthetic matters more than booking velocity.
  • You sell products as much as services.
  • You're fine being one of a thousand sites that look the same.

Choose WordPress if…

  • You already have a developer or agency on retainer.
  • You need a plugin ecosystem the custom world hasn't replicated.
  • You're committed to managing updates and security patches.

Choose custom-coded if…

  • You operate in a competitive Irvine or OC trade and need speed.
  • Rankings, calls, and booked jobs are the only metrics that matter.
  • You want to stop paying rent on a site you'll never fully own.
FAQ

Questions Irvine owners actually ask.

The six we get most often when an HVAC, plumbing, or contracting business in Orange County is deciding between a custom build and staying on a builder. For more, see our full FAQ.

If you want to see the kind of result this stack actually produces in Orange County, our case studies walk through two SoCal service businesses we took from quiet phones to fully booked calendars — one custom Next.js, one Webflow, both indexed and crawled exactly the way Google rewards. The platform choice was the unlock.
