Choosing trade shows is usually done from a category list, a memory of last year and whatever the organiser's sales team said. There is better evidence available for free, published by the fair itself, and it takes about twenty minutes a fair to read: the exhibitor directory from the previous edition.
Decide what you are actually buying first
Attending and exhibiting are different purchases with different break-evens, and conflating them is why the decision feels hard.
- Attending
- A ticket, flights, a hotel and three days of somebody's time. It is a small enough commitment that the right question is whether the floor holds thirty companies worth meeting, and you can answer that from the public directory before you book anything.
- Exhibiting
- Space, build, staffing, shipping and the same travel, and it varies by an order of magnitude between a shell scheme and a custom build. Get your own quote, because any average you read online is describing a different stand from yours. The question is not whether the floor is good but whether your buyers walk that floor looking for what you sell.
The evidence that is free and public
Four things, in the order they are worth your time. All of them are on the fair's own website.
- 1The previous edition's exhibitor directory. This is the strongest signal available and the most ignored. Read the list and ask three questions: are my buyers on it, are my competitors on it, and are the companies on it the size I sell to?
- 2The stated exhibitor and visitor counts, usually in the press pack or the post-show report. Use them to check every other number you are told, including the one on the sales call.
- 3The agenda from last year. Who spoke says more about a fair's centre of gravity than its category label does. A fair whose programme is dominated by procurement talks is a different room from one dominated by engineering ones.
- 4The visitor profile the organiser publishes for exhibitors. Read it as a claim rather than a fact, then check it against the directory. Organisers describe the audience they are selling.
The signal most people read backwards
Your buyers exhibiting is usually a stronger reason to attend than your buyers visiting. Exhibitors are on the floor for three days, in a known location, staffed by people whose job that week is to talk to strangers. Visitors are in the building somewhere.
At industrial and manufacturing fairs this flips the whole decision, because your customers often have stands of their own. A fair that looks wrong on paper, because it is aimed at their market rather than yours, can be the easiest room in the year to sell in.
Your competitors exhibiting is a weaker signal than it feels like. It tells you they believe the fair works, which may be last year's belief, or a sponsorship they are locked into.
A shortlist you can defend
| Check | Where to look | What a yes looks like |
|---|---|---|
| Are my buyers here | Last edition's exhibitor directory and visitor profile | You can name 25 or more companies on the list you would want a meeting with |
| Is the size right | The directory, plus the organiser's stated counts | The companies you named are the size you actually sell to, not four global names and twenty micro-businesses |
| Is it the right room | Last year's agenda and speaker list | The talks are about the problem you solve, not adjacent to it |
| Can we work it | Your own diary and headcount | Somebody has three clear days and will do pre-show outreach two to six weeks ahead |
The fourth check is the one that quietly kills more fairs than the other three. A good fair worked badly returns less than a mediocre fair worked properly, and the difference is almost entirely whether anybody did the research before flying.
Where Pengo helps, and where it does not
This page is the decision Pengo is least of. It has no portfolio forecasting, no event budget planning and no ROI attribution, and if that is what you are buying, event intelligence platforms exist for it. There is a page comparing them: trade show prospecting tools, sorted by what they do.
What it does have is the sweep and the directory. Find fairs is 510 credits, about $2, and sweeps your region and vertical for upcoming fairs, scoring each against a description of who you sell to. Nothing about a fair is bought at that point. It produces the shortlist, and then the shortlist has to be checked the way this page describes.
For a fair you are seriously considering, reading its directory in full is the check. That is priced by the size of the fair, from 1,500 credits for up to 100 stands, and it answers the first two rows of the table above with a list rather than an impression. The same purchase is the target list if you go. Before you buy anything, the fairs already on file carry a stand count and an industry mix, and browsing by month is how to see what is opening in the quarter you are planning.
Questions
How do you decide which trade shows to attend?
Read the previous edition's exhibitor directory before anything else. It is free and public. Ask whether you can name 25 or more companies on it worth meeting, whether they are the size you sell to, and whether last year's agenda is about the problem you solve.
What is the best free evidence about whether a trade show is worth it?
The previous edition's exhibitor list, published on the fair's own website. It tells you who was actually there rather than who the organiser says attends, and it takes about twenty minutes to read.
Should I attend or exhibit?
Attend first if you are unsure. Attending costs a ticket, travel and three days of time, and you can judge it from the public directory beforehand. Exhibiting is a much larger commitment that varies enormously by stand size and build, so get your own quote rather than trusting a published average.
Is it a good sign if competitors exhibit at a show?
It is a weak signal. It tells you they believed the fair worked, possibly last year, possibly under a sponsorship commitment. A stronger signal is whether your buyers exhibit, because exhibitors are in a known place for three days with staff whose job is to talk to visitors.
How far ahead should I plan a trade show?
Choose the fairs a quarter or more out, then do the exhibitor research two to six weeks before the show. Earlier than that the directory is still filling up, and later leaves no time for pre-show outreach.
Can Pengo tell me which trade shows to attend?
It can produce a scored shortlist. Find fairs is 510 credits, about $2, and sweeps your region and vertical, ranking each fair against who you sell to. It has no portfolio forecasting or ROI attribution, so the shortlist still needs the checks on this page.
