BuiltWith just launched a new feature on free and detailed profiles: Site Age. 🎉

Site Age shows when a domain was first registered (or our oldest known registration date) for certain domains. This adds a new layer of historical context to any profile—helping you quickly identify how long a site has been established online. 🌐

📌 Why Site Age matters

When you’re researching a company, a market, or a list of prospects, domain age can be a powerful signal. Older domains often correlate with long-running brands, durable operations, and established web presence. 🧠

Now you can combine Site Age with BuiltWith’s technology detection to find sites that are both established and technologically interesting. 🔍

💾 Example: dec.com (1985!)

Some domains go way back—like dec.com, which shows a Site Age of September 30th, 1985. 🤯

That means you can surface some of the oldest “first detected” technology records on BuiltWith—perfect for historical analysis, discovery, and high-confidence targeting. 🧾

🏛️ New trend: Pre-Year-2000 Technology

To make this even easier to explore, we created a new BuiltWith “technology” segment: Pre Year 2000 🧠✨

These are sites where the domain dates back to the pre-2000 internet—true early-web survivors. 🕸️

📈 Use Site Age in Pro reports to find ultra-established sites

Site Age isn’t just trivia—it’s a practical metric you can use for filtering and prioritization. ✅

In BuiltWith Pro reports, you can use Pre-Year-2000 to identify super established sites for sales, partnerships, competitive research, or market mapping. 💼
