Thousands of new startups establish their web presence every day. Knowing when a competitor first went online is one of the most underused signals in competitive intelligence.
Check web presence age instantly →AI coding agents, no-code platforms, and cloud infrastructure have dramatically lowered the barrier to launching a product online. What once took months now takes days. A solo founder can ship a full web application in a weekend.
The result: thousands of new domains are registered and go live every single day. For researchers, investors, and businesses, this creates a challenge: how do you track what is new, what is established, and what has staying power?

A domain registration date is a matter of public record. It marks the moment a business or individual staked out their web presence. Combined with other signals, it reveals a great deal:
Domain age pinpoints the earliest moment a company began building its online presence, often before press coverage, funding announcements, or product launches become public.
A company with a 10-year-old domain has a decade of SEO authority, customer trust, and operational experience. A 6-month-old domain is still unproven. This context matters when sizing up competition.
A cluster of domains in a niche all registered around the same period signals that a market trend was emerging at that time. Tracking when competitors started reveals where the market was heading.
When a company claims to have been operating for 5 years, the domain registration date provides an independent, verifiable data point to cross-reference that claim.
Monitoring domain age in your industry lets you spot new competitors before they have marketing budgets, press coverage, or significant search visibility.
Domain age contributes to a site's SEO authority. Older domains with a history of content are often more valuable in acquisitions than newly created ones.
The rise of AI coding tools like GitHub Copilot, Cursor, and fully autonomous coding agents has compressed the time from idea to live product to almost nothing. This means the market is being flooded with new entrants at an unprecedented rate.
For analysts and researchers, this creates both an opportunity and a noise problem. Domain age helps cut through that noise:
Signal vs. noise: A startup that registered its domain 3 years ago and is still operating has survived the hardest phase. A site registered last month is still an unknown. Domain age is a fast, objective filter that separates established players from newcomers, without reading a single line of their marketing copy.
Use PhDAPI's domain search to look up the age of each competitor's domain. Note registration date, registrar, and expiration date to understand their commitment level.
As you browse competitor sites, investor pages, product directories, and news articles, the WebsiteAge extension automatically shows domain age without interrupting your workflow.
Compare domain registration date with Crunchbase funding rounds, press coverage, and product launches. Gaps between domain registration and public activity can indicate stealth periods, pivots, or acquired domains.
When researching a category, note which players have domains registered in the last 6–12 months. These are your newest competitors, the ones that have not yet appeared in most industry analyses.
Combine domain age with web traffic estimates, backlink counts, social media activity, and job postings for a fuller picture of competitive maturity. Domain age is your fastest first filter.
Domain age lookup is used across a wide range of professional contexts:
See web presence age on every site you visit, with no manual lookups required.
