How we verify conference data
364 upcoming events under continuous verification
"Verified" is the whole point of this directory, so here is exactly what that word means — what gets checked, against which source, and how often.
Official-domain link checks
Every listing must link to the conference's official website. URLs on aggregator or ticketing domains (Eventbrite, Meetup, form builders) are flagged as unverified and excluded from the "Visit Official Website" button until a genuine official domain is confirmed. All stored URLs are re-tested for reachability on a rolling basis; dead links are marked and re-hunted.
Dates & CFP deadlines against the source
Dates come from the organizer's own site or from community-maintained datasets that reference it, and are re-checked when sources disagree. Call-for-Papers deadlines are verified against the official CFP page; expired deadlines are removed automatically at three separate layers, so a closed CFP is never shown as open.
Daily refresh, multiple sources
The directory syncs daily from several independent sources, with fuzzy de-duplication (normalized names, official domains, dates and cities) so the same event never appears twice. Conflicting entries are resolved in favour of the organizer's official page — including manual verification for edge cases.
Past events removed, links preserved
When a conference ends its page is retired, and the address permanently redirects to the next edition of the same conference as soon as it is announced — so bookmarks, badges and search links keep working across years.
User submissions are reviewed by a human
Conferences submitted through the site are checked against their official website — exact name, dates, and location — before an editor approves publication. Nothing goes live automatically.
Travel notes written per conference
Destination sections are written individually for each conference around its actual venue and season, and pass an automated similarity gate so that two conferences in the same city never share recycled text. Practical details like transit times are stated conservatively and should always be confirmed before travel.
What we decline to list
A directory is defined as much by what it keeps out as by what it lets in. conventions.io lists 364 upcoming conferences rather than hundreds of thousands, because every listing has to clear the checks above — and events matching the following categories do not make it in:
No identifiable organizer
Events with no named organizing body reachable through a working official website.
Template event series
Near-identical “conference” pages replicated across many unrelated disciplines or cities, with little more than the name and location swapped.
Pay-to-present formats
Events presented as peer-reviewed conferences where acceptance is effectively immediate and tied to a fee, without a genuine review process or a published committee.
Unverifiable history
Events advertising a long-running edition number whose previous editions left no public trace we could confirm.
No official home
Listings that point only at ticketing, form or aggregator pages instead of an official conference website.
Unconfirmable basics
Events whose dates, venue or format cannot be confirmed from any primary source at the time of review.
These are editorial criteria, not accusations — we publish no lists of names, and a declined event can always qualify later by meeting the bar above. Borderline cases are reviewed by a human, and when in doubt, we leave it out.
Found an error? Data quality is a process, not a promise — if you spot an incorrect date, a dead link or a duplicate, tell us and it will be fixed within a day. Organizers can also submit their conference or grab a verified-listing badge. Always confirm final details on the official conference website before booking travel.
