Bulk website last-updated checker: find date hints on every website in your list
In short: Paste a list of websites and see the date hints each home page gives away: the Last-Modified header, modified-time meta tags, structured data and the copyright year, as a CSV. Limit: Home page only: its response headers and the first 128 KB.
A bulk website last-updated checker reads the date hints in each home page. Paste up to 100 websites, or 500 after a free Google sign-in; each row lists the Last-Modified header, modified-time meta tags, JSON-LD dateModified and copyright year it found, with the newest date. Hints, not proof of when a person edited the site. Download the CSV.

How do I find out when many websites were last updated?
- Paste up to 100 sites, or 500 after a free Google sign-in, one per line; email addresses and URLs work too, and the domain is taken from each. You can also upload a CSV.
- Press Look for update hints. Each home page is requested once, over HTTPS and then HTTP; the response headers and the first 128 KB of the page are read.
- Read each row: Date hints found, with each hint, its date and where it came from, plus the newest dated hint, or No date hints.
- Sort the CSV by the newest hint and set aside sites with only an old copyright year.
Example
- You enter
- Three sites:
acme.example(a modified-time tag and a current copyright year),globex.example(only a 2019 copyright line) andinitech.example(no dates). - You get
- acme.example: Date hints found, the modified-time tag with its date and the copyright year, with the newest date in the summary. globex.example: Copyright year 2019 only. initech.example: No date hints. Download the CSV.
- Limits
- Up to 100 a run without an account and 500 when signed in with Google, counted over a minute. 10 sites a request; one GET of the home page from our server, no cookies, nothing stored.
Which date hints does a home page give away?
Four places carry dates. The Last-Modified response header, defined in RFC 9110, says when the server believes the page last changed. Meta tags such as article:modified_time and og:updated_time are set by publishing software. Structured data can hold a dateModified. And the footer usually has a copyright year.
The tool reads all four and shows each one with its source, so you can see which is which. The newest full date is shown in the summary.
Why are these hints and not an answer?
A Last-Modified header on a dynamic site often shows when the server built the page, which can be today. Many sites print the current year in the footer automatically, so a fresh year can sit on a site nobody has touched in years. An old year, though, is a better sign: a footer that says 2019 on a site that prints a fixed year suggests it was last edited around then.
Read the hints together. For whether the site answers at all, use the bulk website status checker; to see who hosts it, use the website host checker.
How do you use update hints in outreach?
Use them to put living sites first and to question the ones that look abandoned. A closed business still has a website, and its addresses bounce. Before a send, verify the addresses on the rows you keep.
Pair the hints with the bulk website title checker to see what each site says it does, and with the bulk website CMS detector to see how it is built.

Common questions
- How do I check when a website was last updated?
- Paste the site into a bulk last-updated checker like this one. It reads the Last-Modified header, modified-time meta tags, structured data and copyright year on the home page.
- Is this last-updated checker free?
- Yes. 100 sites a run without an account, 500 after a free Google sign-in, with no card, and a CSV download.
- Does it tell me exactly when a site was edited?
- No. It shows hints. A header can show when a server built the page, and a footer year is often printed automatically.
- Why does a site show no date hints?
- No date was in its headers, meta tags, structured data or copyright line. That doesn't mean it is out of date.
- What does an old copyright year mean?
- On a site that prints a fixed year, it suggests the footer was last edited then. On one that prints the current year automatically, a recent year says nothing.
- Does it check other pages?
- No, only the home page.

A tidy list can still be full of dead addresses.
Extracting, deduplicating and syntax checks all work on the text of an address. None of them can tell whether the mailbox exists. Only the server that hosts it can answer that, through an SMTP check, and that is what the paid product does.
- Upload the cleaned file as it is: CSVs up to 100,000 rows
- A real SMTP mailbox check on every row, with catch-all detection
