Ask ten people what makes a good logo and you'll get ten answers, most of them about whether they personally like the colour. But a logo isn't a piece of art you hang on the wall and admire. It's a working tool. It has a job to do, in shop windows and on invoices, on a phone screen the size of a thumbnail and on a van doing 40 down the A120. Judged that way, "good" stops being a matter of taste and becomes a matter of whether the thing actually does its job.
Here's what separates a logo that earns its keep from one that just looks nice for a fortnight.
A logo is not your brand
First, a useful bit of ground-clearing. Your logo is not your brand, any more than your face is your personality. Your brand is the whole impression people form of you: how you answer the phone, how quickly you reply to an email, whether the work is any good. The logo is the shorthand that calls all of that to mind in an instant.
That matters because it lowers the stakes in a helpful way. A logo doesn't need to explain what you do, tell your life story, or win a design award. It needs to be recognisable, appropriate, and easy to use everywhere. Apple's logo is an apple. Nike's is a tick. Neither tells you a single thing about the product, and both are worth a fortune, because years of good work have been poured into them and the mark simply became the handle people grab hold of.
The five things that actually matter
Designers have argued about this for decades, but the fundamentals are remarkably settled. A good logo is simple, memorable, timeless, versatile and appropriate. Get those five right and you're most of the way there.
Simple
Simple logos are easier to recognise, easier to remember and easier to reproduce. Think of the marks you can picture right now with your eyes shut: they're almost all clean and uncomplicated. Complexity is the enemy here. Fine detail, gradients that fight each other, three typefaces where one would do, a little illustration of your actual shopfront. It all falls apart the moment the logo has to be small, and these days it's small a lot of the time.
A good test costs nothing: could you describe your logo to someone over the phone and have them sketch a rough version? If the answer is no, it's probably too complicated.
Memorable
Recognition is the whole point. A memorable logo tends to have one clear idea rather than five competing ones, a distinctive shape or a clever bit of thinking that gives the eye something to hold on to. You're not aiming for a design people gasp at. You're aiming for one they recognise on the second, third and hundredth glance without having to think about it.
Timeless
Trends are tempting and they age badly. The swooshy gradients of the early 2000s, the letterpress-and-banner look that was everywhere a decade ago, whatever effect is fashionable this year: it all dates, and re-branding is expensive and confusing for customers. A good logo should still look right in ten years. That usually means leaning on solid fundamentals such as good proportion, sensible type and a strong core idea, rather than chasing whatever's trending on design blogs this month.
Versatile
This is the one most people forget, and it's the one that bites hardest. Your logo has to work in a huge range of places: a tiny favicon in a browser tab, a social media profile picture cropped into a circle, an embroidered polo shirt, a black-and-white letter, a sign across the front of a building. If it only looks good large, in full colour, on a white background, it isn't finished.
In practice, versatility means a few concrete things. The logo should work in a single colour, because sometimes you only get one. It should have a version that holds up when it's tiny. And it usually needs a couple of variants, such as a full "lockup" with your business name and a compact icon-only mark for those little square spaces, so you're never forced to squeeze a wide logo into a slot it was never meant for.
Appropriate
Appropriate doesn't mean literal. A children's nursery and a firm of solicitors should not feel the same, but the nursery's logo doesn't need to contain a child and the solicitor's doesn't need a set of scales. Appropriate means the tone fits: the colours, the typeface and the overall feel should suit the business and appeal to the people you actually want as customers. A friendly, rounded, colourful mark says something very different from a spare, sharp, monochrome one, and both are right for the right business.
The practical stuff nobody tells you
A logo is a deliverable, not just a picture, and there are a few things worth getting right so you're not paying for the same job twice.
You want your logo as a vector file, usually an SVG or EPS. Vectors can be scaled to any size, from a business card to the side of a lorry, without going blurry. A single low-resolution JPEG pulled off an old website will let you down the first time you need it big. A proper handover includes the vector master files, everyday formats like PNG for the web, and ideally a short note of your exact brand colours and fonts so everything stays consistent.
It's also worth thinking about where the logo will actually live before it's designed, not after. If most of your customers will meet you online, the mark needs to earn its place as a tiny app icon and a social avatar. If you're a trade business, it needs to read clearly on a van and a uniform from across a car park. Designing with the real-world uses in mind is the difference between a logo that works and one that merely exists.
What good actually costs you when it's bad
Cutting corners on a logo rarely saves money; it just delays the cost. The cheap-marketplace or AI-generated route often produces something that looks fine on screen and then quietly causes problems: no vector files, so it can't be printed properly; a design that turns out to be sold to a dozen other businesses too; colours that were never defined, so nothing matches. You end up paying a designer to redo it, plus reprinting everything it appeared on. Doing it once, properly, is almost always cheaper in the end.
A quick sanity check
Before you sign off on any logo, run it through a short list. Does it still work in black and white? Is it clear at the size of a postage stamp? Could someone describe it down the phone? Does it feel right for the customers you actually want? Will it still look sensible in ten years? Do you have it as a proper vector file? Five yeses and you've got something that'll serve you for a long time.
Getting a logo right is one of those jobs that looks simple and rewards experience, because so much of the work is in the restraint.
