Las Vegas hosts more than 22,000 conventions a year. The big ones — CES (180K+ attendees), World of Concrete, MJBizCon, NAB Show, SEMA — pull 30–180K decision-makers into the city for 3–5 days. Every one of those people Googles exhibitor names. If you're exhibiting, your website will see traffic it has never seen.
I get an emergency call about a buckled exhibitor site roughly every January. The fixes are predictable; the prevention is straightforward. Here's the playbook.
Why exhibitor sites fail (and it's never the reason you think)
When a Las Vegas exhibitor site crashes during show week, it's almost never because they ran out of server capacity. The actual failure modes:
- 1Form endpoints aren't cached. The homepage caches fine; the 'request a demo' POST hits a slow database query for every submission and falls over at 40 req/sec.
- 2Auto-playing hero video pulls 8 MB per pageview. Two days into the show, the bandwidth bill hits a circuit breaker.
- 3WordPress + 30 plugins, no page cache. Each PHP request takes 1.2 seconds. At 200 req/sec, the server queues forever.
- 4Third-party scripts (chat widgets, marketing pixels) are the actual blocking resource. Your site responds in 200ms; the user's browser waits 6s for Intercom to load.
- 5Mobile drops to 2 bars at the convention center. Anything heavier than 1.5MB total weight times out.
The 30-day prep timeline
- T-30 daysBaseline + audit
Record current Core Web Vitals. Run k6 or Loader.io load test at 50× current traffic. Identify the slowest 3 endpoints.
- T-21 daysCache + CDN
Put Cloudflare or Vercel in front of everything. Cache HTML aggressively. Set a 1-week TTL on images, JS, CSS. Verify with curl.
- T-14 daysStrip the bloat
Replace auto-playing hero video with a poster image + click-to-play. Audit third-party scripts. Defer everything that isn't critical. Target sub-1.5MB total page weight.
- T-7 daysForm path stress test
Submit your 'request a demo' form 500 times in 60 seconds. If it queues, fix it. Often: move form submissions to a background queue, return 200 immediately.
- T-2 daysBooth banner + warm cache
Push the 'Meet us at booth #1234' banner live. Pre-warm cache with a synthetic crawl. Confirm uptime monitoring is paging you, not your dev shop.
- Show weekWatch real-time + ship fast
Dashboard open. One person on standby to push a fix. Daily check-in at 7am Pacific to look at the prior day's funnel.
The booth conversion banner that actually works
Most exhibitor websites have a 'Contact us' CTA during show week. Wrong CTA. The right one tells the visitor where to find you on the floor.
The pre-show checklist
Common show-week mistakes
Mostly yes for traffic; the platform handles scale. The pitfalls are different: heavy embedded video, third-party widgets, and forms that don't async. Still need to audit weight and form behavior.
Almost never. Servers aren't usually the bottleneck — it's a single slow DB query, a synchronous API call, or unoptimized images. More servers just spread the problem.
Best plan for first-time exhibitors with tight budget. A dedicated landing page at /show or /ces with the booth number, demo signup, and one strong CTA. Push paid traffic and QR codes there, not your homepage.
Pre-stage the email sequence before the show. Day +1: thank you + meeting recap. Day +3: case study or demo video. Day +7: book a call. Lead quality from in-person is 5-8x web leads; don't let them go cold.
World of Concrete is 65K+ attendees over 3 days at the Las Vegas Convention Center — bigger than most cities' biggest event. Yes, all of it matters. The MJBizCon, NAB, SEMA, and ConExpo crowds all behave the same way.
“Our site went down for 6 hours during day 1 of CES 2024. We rebuilt the whole front-end in 8 weeks for the next show. CES 2025 we did 14,000 form submissions over 4 days, zero downtime.”
