Construction SEO Benchmarks: 2024 vs. 2025

When we first launched our Construction SEO Report in early 2025, we benchmarked every website on the ENR Top 400 Contractors list (2024 edition). Just a few months later, we recalculated the numbers for the 2025 list.

What changed?

• List turnover: Approximately 9% of firms on the 2025 list were new , providing us with a fresh set of websites to evaluate.
• Backlinks increase significantly: The median number of backlinks grew from just over 1,000 to more than 1,700, a strong signal that contractors are investing more in their digital presence.
• Domain authority flatlined: The average DA dipped slightly from 33 to 32.
• Speed stayed steady: Desktop and mobile performance barely budged, with contractors holding at mid-70s for desktop and mid-50s for mobile.
• Spam scores crept higher: The average moved from 6 to 7, but the median spam score stayed at 2.

Why it matters Your competitors are getting stronger online. The firms that dominate visibility today will shape perception, attract talent, and win tomorrow’s projects.

Not that surprisingly, design firms edge out contractors across nearly every metric . The gap matters when prospective clients, recruits, and AI-driven search engines are looking for signals of credibility and relevance.
