Open Day and Trade Fair: Fill Events via Your Website

Announcement, signup, reminder and follow-up: how an event page is built, how much lead time it needs and which details search engines read out of it.

14 min read VeranstaltungAnmeldungStrukturierte DatenLokale Sichtbarkeit

An open day, a workshop festival, a course or a stand at the regional trade fair: the work sits in the preparation, the return depends on who hears about it in time. Your own website is among the few invitation routes you control yourself, at a fixed address, with complete details, without a distribution mechanism owned by someone else. This article shows how an event page is built, how much lead time it needs, which details search engines read out, how a signup form stays data-thrifty and what happens to the page after the date.

That place is your own page. A notice in the shop window reaches the people walking past. A post in a social network reaches those it is shown to and then slips out of the feed. A page on your own domain, by contrast, sits at a fixed address, fits on a poster, a flyer, a vehicle and an invoice, and answers questions at ten in the evening as well. How local visibility comes about day to day is described in the article on local visibility for local businesses.

  • A fixed address that fits on flyers, posters and vehicle lettering and still delivers something after the date has passed.
  • Complete details on date, time, address, parking, access and programme, so nobody has to pick up the phone.
  • One signup route that can be counted and tells you how many chairs, portions or course places to hold ready.
  • Machine-readable key facts, so date and place appear correctly in search results and map services.
  • A follow-up that turns one-off interest into a lasting connection instead of removing the page the day after.

Even seasoned exhibitors work hard for visitors

For the AUMA exhibitor outlook 2026/2027, 404 companies (AUMA) were surveyed in October and November 2025, predominantly small and medium-sized businesses. 44.1 percent (AUMA exhibitor outlook) of them name winning over and activating visitors as a substantial challenge. At the same time, trade fair participation ranks among the most highly rated measures in the marketing mix with 77.5 percent (AUMA exhibitor outlook) top-two mentions, and 64.6 percent (AUMA exhibitor outlook) expect trade fair participation to carry the same weight over the coming five years as it does today. So the effort pays off, but the invitation decides.
  1. Eight to five weeks before: announcement. The page goes live with date, place and one sentence on the occasion, even if the programme still has gaps. What matters is the address, not completeness.
  2. Six weeks to one week before: signups open. Switch the form on, name the number of places, send confirmations automatically. From now on every signup shows whether the wording carries.
  3. Two weeks to the day before: reminder. Those signed up receive a message with directions and times, the page gets the finished programme, remaining places are named.
  4. The date itself. The page carries the day's schedule, a phone number for questions and a note on whether walk-in guests are welcome.
  5. Up to two weeks after: follow-up. Thanks, images, outcome and the next date. The address stays in place and becomes the template for next year's repeat.

This split has a practical reason: each stage has its own job and its own audience. The announcement speaks to people who have no diary entry yet. The reminder speaks to people who have already decided. Anyone packing both into one message loses at both ends. Write the plan down once and it can be reused for every further event, so the second round costs a fraction of the time. How a page of this shape comes about in the first place is shown in the overview of how it works.

What belongs on the event page

An event page is not a small home page. It answers a handful of concrete questions in the order in which they arise: what is this, when, where, what does it cost, do I have to sign up, how do I get there. Everything else is trimming.

Six building blocks carry the bulk of it, and as a rule they fit on a single page, with no sub-pages and no menu.

Date and time written out

Start and end with the weekday, not just a string of digits. Multi-day dates get one line per day, so nobody has to guess when the grill stand opens.

Street address, not a town name

Street, house number, postcode and town. A bare town name is not enough for navigation and is of little use for the markup either.

Programme with times

Tours, demonstrations and talks with a start time. Someone who knows the workshop tour begins at 2 pm plans the visit instead of considering it.

Signup or a clear waiver

Either a form with a number of places or a clear note that no signup is required. The ambiguity in between puts off the uncertain guests.

Access and step-free routes

Steps, lift, accessible toilet, gravel or asphalt on the site. Two sentences save people with a walker or a pram a phone call and a cancellation.

Directions, parking, stop

Where to park, how many spaces there are and which stop is nearby. On the day itself this is the most-read section of the page.

The one-screen test

Open the draft on a phone and look at what is visible without scrolling. If occasion, date, time and place are in that section, the page is finished enough to go live. If one of them is missing, it moves up before any detail gets discussed. How finished pages of this shape feel is shown by the example pages.

Structured data: the entry search engines read

An event page can additionally supply its key facts in machine-readable form.

This is no longer a fringe topic: according to the Web Almanac 2025, 50 percent (Web Almanac 2025) of the home pages examined use structured data, on desktop as on mobile, up from 48 and 49 percent respectively the year before. What matters is where the markup sits: only 2 percent (Web Almanac 2025) of crawls found structured data that was added by JavaScript. The details belong in the delivered HTML, not in a script that loads later.

Google Search Central lists the name, the start date and the location with name and address as required properties for the Event type (Google Search Central). Recommended additions are description, end date, event status, attendance mode, image, offers and organizer. Two notes from the same source save trouble: the name of the venue does not belong in the event name field, and extraneous information such as URLs, prices or performers has no place there either. How markup works in general is covered in the article on structured data in search results; that the date also belongs in a maintained business profile comes on top.

  • Name of the event, without additions such as the venue or a promotional call
  • Start date with time zone, plus the end date for multi-day events
  • Location as a Place with a full postal address, not just a town name
  • Event status, as soon as the date is postponed or cancelled
  • Attendance mode, if the date runs on site, online or as both
  • Offer with price and currency, as soon as admission is charged

You must include the required properties for your content to be eligible for display in enhanced search results.

Google Search Central, structured data documentation for events
  • Name as a required field, so the signup stays attributable
  • Email address or phone number as one return channel, not both as required
  • Number of people, if places, chairs or catering are being planned
  • Preferred time slot, if tours run in groups
  • Free-text field for notes such as wheelchair, allergy or pram, optional
  • Postal address, date of birth and company name are dropped as long as no contract is concluded

The notice text is required, not optional

Article 13 of the General Data Protection Regulation requires you to inform people at the time the data are obtained about the controller, the purposes and the legal basis (GDPR). One sentence under the form with a link to the privacy policy is usually enough, but it has to be visible before anything is submitted. Add how long the signup list is kept and when it is deleted. What is needed behind the scenes is described in the article on legal pages for imprint and privacy.

Technically a signup form carries the same load as an enquiry form: encrypted transmission, labels that screen readers can read out, and a confirmation page that does more than say thank you and repeats the date and time. Anyone already running an enquiry route can reuse it; the article on the contact form and its enquiries describes the structure, and the article on online appointment booking for businesses shows how a calendar grows out of it. For recurring courses with fixed start dates, the article on the driving school website with courses and signups is worth a look.

The line between reminder and advertising

Under section 7 paragraph 2 number 2 of the German Act against Unfair Competition, advertising using electronic mail without the prior express consent of the addressee is regarded as an unreasonable nuisance (UWG). Paragraph 3 allows a narrowly drawn exception for existing customer relationships, tied to four conditions, among them a notice about the right to object on every use. In practice this means: for the reminder about the booked date you need no consent. For the newsletter you would like to send afterwards, you do. So both belong in two separate checkboxes, not in one.

If the event charges admission and is booked online, distance selling law comes into play. Section 312g paragraph 2 number 9 of the German Civil Code exempts contracts for services connected with leisure activities from the right of withdrawal, provided the contract specifies a specific date or period for performance (BGB). For a concert, a wine tasting or a workshop festival with a fixed date, that exception applies as a rule. It does not release you from informing people: anyone not granting a right of withdrawal says so before the booking rather than explaining it afterwards.

  • The day's schedule right at the top, with times and meeting points, not below the directions.
  • The phone number as a dial field, so one tap is enough instead of copying the number out.
  • Directions and parking in a section of their own, as described in the article on the directions and location page.
  • A note for walk-in guests on whether places are still free, in one sentence that can be changed in two minutes.
  • A short loading time, because visits on the move run over mobile networks and patience is scarce there.
  1. Thanks and a review within three days. A short text, three to five images, one figure if it is sound. The announcement page becomes a review page, the address stays the same.
  2. Make the outcome visible. Anyone who filled apprenticeship places or started conversations at the open day writes that in one sentence. In the German skilled trades, according to the German Confederation of Skilled Crafts, around 346,000 (ZDH) young people are in qualified training; for many businesses the workshop festival is the first contact with exactly that group.
  3. Announce the next date. Even without a fixed date, the approximate period and a way to be notified are enough. How to collect such a signup properly is covered in the article on newsletter signup with double opt-in.

Photos from the day

For photos in which guests are recognisable, section 22 of the German Act on Copyright in Works of Fine Art and Photography applies: portraits may only be disseminated or publicly displayed with the consent of the person depicted (KunstUrhG). In practice this means a notice at the entrance typically does not replace consent for a portrait, whereas overview shots without identifiable individuals are considerably less critical. From employees, consent is obtained in writing. Which subjects are worth the effort and what rights hang on them is set out in the article on photos, image rights and subjects.

Common mistakes and what carries instead

Scroll table sideways

What often happensWhat it costsWhat carries instead
Page goes live ten days beforeToo little time for the diary entryAnnounce eight weeks out, add the programme later
Town name instead of a street addressNavigation and markup stay impreciseStreet, number, postcode and town in one block
Signups by email to a mailboxNo count, no confirmation, plenty of manual workForm with a confirmation page and an automatic reply
Twelve required fields in the formDrop-offs and data nobody needsName, one return channel, number of people, the rest optional
The date lives only in a social networkReach ends with the feed, no search resultYour own page as the target, the network points to it
Page deleted after the dateDead links on flyers, follow-up lostThe announcement becomes a review at the same address

The last point deserves a note, because it is quietly expensive. A deleted event page leaves dead links on flyers, in press releases and in other people's calendars, and those persist for years. If the address stays and the content is swapped, every printed reference keeps working. If the address cannot be kept for once, a redirect to the successor page is set up rather than leaving an error page standing.

A schedule you can reuse

The effort of the first event page sits in the structure, not in the text. Settle it once and next time you only refill date, programme and images.

The following plan can be filed in the business and ticked off before every date; it fits the workshop festival as well as the information evening or the stand at the regional fair.

Schedule for an event, counted back from the date
Week -8   Create the page: title, date, address, one paragraph on the occasion
          Fix the URL and make it known inside the business
Week -6   Switch on the signup form, enter the number of places
          Add structured data for the date
Week -4   Add the programme with times, place the images
          Send the URL to print for flyers, posters and vehicles
Week -2   Remind those signed up, name remaining places on the page
          Check directions, parking and step-free access
Day  -1   Move the day's schedule up, check the phone number as a dial field
Day   0   Short note for walk-in guests, change nothing else
Day  +3   Review: thanks, images, one sentence on the outcome
Week +2   Name the next period, offer a notification
  • One address for every print run. Flyers from last year keep working if the page at the same address carries the new date; how a printed reference leads there cleanly is shown in the article on QR codes and landing pages in offline advertising.
  • One form instead of a mailbox. Signups are countable, confirmed and in one place, even when two people look after them.
  • One data set for search engines. Date and place sit machine-readable in one spot and are maintained there whenever something changes.
  • A review instead of a gap. The page stays useful after the date and becomes the template for the repeat. How a whole page tree grows out of this is shown in the article on service pages with one page per service; for questions about the implementation, the route runs via contact.
