The Shortcut to Page 1: How Custom Code & Lighthouse Scores Break the "90-Day SEO Curse

If you ask a typical web developer about Google Lighthouse, they might roll their eyes and call it a "vanity metric." But if you ask a Google engineer, they will tell you it is a ranking signal.

At Ten Ken Group, we view Lighthouse scores not just as a technical benchmark, but as a velocity lever.

Most businesses accept the industry standard that SEO takes 60 to 90 days to "kick in." They launch a site and wait three months for the needle to move. We refuse to accept that timeline. By utilizing high-performance custom code and aiming for perfect Lighthouse scores, we regularly see that timeline cut in half.

Here is why speed is your secret weapon for hitting the #1 spot.

The "Crawl Budget" Economy

Google’s bot is busy. It has billions of pages to index every day. If your website is built on a heavy platform like WordPress or Wix, it is filled with "code bloat"—unnecessary themes, plugins, and scripts that the bot has to wade through.

When a site is slow or heavy:

1. Google crawls fewer pages per visit.
2. Google takes longer to understand your content.
3. You wait 90 days to rank.

When a site is custom-coded and optimized for Lighthouse:

1. The code is lean and instantly readable.
2. Google categorizes your site faster.
3. You can start ranking in 30-45 days.

The Problem with Wix, WordPress, and Squarespace

To understand why custom code wins, you have to look under the hood.

Platforms like Wix and WordPress are designed for "ease of use," not "performance." To make drag-and-drop features work, they load massive libraries of code—even if you aren't using them. This is like packing for a weekend trip but bringing your entire wardrobe.

The "Bloat" Comparison:

• WordPress/Wix: A simple homepage might require 2MB of JavaScript to load.
• Ten Ken Group Custom Code: That same homepage can be built with 50KB of JavaScript.

Google notices this difference. A clean, lightweight site signals "Technical Superiority." When Google sees a 100/100 Performance score, it trusts that users will have a great experience. This trust is what pushes you past competitors who are stuck in the "yellow" zone, helping you secure that coveted #1 spot.

The 3 Metrics That Drive Rankings

You don't need a perfect score for vanity; you need it for velocity. Focusing on these three Core Web Vitals accelerates your SEO:

1. Largest Contentful Paint (LCP)

• The Reality: If your page takes 4 seconds to load, Google pushes you down the rankings to protect its users from frustration.
• The Custom Advantage: With custom code, we don't rely on heavy plugins. We hard-code the hero section to load instantly, signaling to Google that your site is premium.

2. Cumulative Layout Shift (CLS)

• The Reality: Pages that jump around while loading (common in drag-and-drop builders) are penalized.
• The Custom Advantage: We define the exact pixel dimensions of every element in the code. The browser knows exactly what the page looks like before it even downloads the images. Zero shift. Maximum trust.

3. Total Blocking Time (TBT)

• The Reality: This is the silent killer of mobile rankings. It happens when heavy scripts freeze the screen.
• The Custom Advantage: We audit every line of script. If it doesn't add revenue, it doesn't go on the site.

Stop Waiting 90 Days

Your developers might say Lighthouse doesn't matter because "users don't care about code." But Google cares.

If you are tired of waiting quarters to see ROI from your SEO efforts, the problem likely isn't your keywords—it’s your infrastructure. Custom code is the fast lane to the top of the search results.
