Why does your brand need brand guidelines?

What does consistency actually do for a brand?

At uni I had a lecturer who taught me something called IMC, or integrated marketing communications. The idea is simple. You build an experience of your marketing so people have the same experience across different touchpoints.

His bad example was a big fast food chain. The ads were built around one theme, and then you walked into a restaurant that looked like a retro diner. Two different brands under one name. His good example was a rival whose ads, stores and packaging all felt like the same place.

That lesson has stuck with me for years. You build trust by being consistent across different areas, and when it’s done really well, you build really big brands. When the advertising promises one thing and the real-world experience delivers another, you erode trust. A clever ad can buy attention. Consistency is what turns that attention into trust, and trust at scale is what makes a brand big.

Where does the experience usually break?

The website, more often than anything else.

I spoke with a brand recently that had standout packaging. Real care had gone into it. Their website was about ten years old. So I asked the director: why have such amazing packaging and then a website that lets it down?

The website is an extension of the packaging experience and the product experience. For a stranger, it often comes first. They haven’t held your box or opened your product yet. The site is where they decide whether you’re worth the money, and if it feels dated, all that work on the packaging never gets a chance.

Other common breaks:

• An ad that looks premium, landing on a page that looks like a discount warehouse.
• Emails that read and look like they came from a different company.
• Banners and graphics made one at a time, each in a slightly different style.

What makes a brand feel premium?

One of the things that makes a brand feel premium is this thing called touchpoint cohesion. It’s the small visual cues staying consistent across your website, social and email.

Mismatched icons, random font weights, a heading hierarchy that changes from page to page. None of these on their own will lose you a sale. Together they’re speed bumps. Each one chips away at trust a little, and customers feel it even if they couldn’t tell you why.

How do you check whether your brand is cohesive?

When we assess a new brand, I want a cohesiveness audit in there. You can run it yourself in an hour.

1. Open the Meta Ad Library and screenshot the ads you’re running now.
2. Pull up your last handful of emails.
3. Open your website on your phone and click through the homepage, a product page and the cart.
4. Put them all side by side and ask two questions. Does this feel like one brand? Is it communicating the same things?
5. Write down every mismatch you spot: fonts, icons, colours, hierarchy, tone. Those are your speed bumps.

If it doesn’t feel cohesive, that’s a strong sign you don’t have a good brand design system. It also points to confusion in the customer journey, and confusion drags down performance. Growth comes from balancing performance and brand. Ignore the brand side long enough and your ads start working harder for less.

What should a brand guideline do for you?

Give everyone who touches your brand the same rules. Get a designer to build it. It should spell out your fonts and the weights you use, your icon style, your colours, and how headings and body copy stack on a page, so a new email or landing page looks like it belongs.

One brand I reviewed had never had a guideline. They were using ChatGPT to make banners and illustrations, and you could see the dilution across the site. Nobody had done anything wrong on purpose. Each asset was a little off from the last one. Without the right instruction, everything gets diluted bit by bit.

How do you stop AI tools diluting your brand?

Turn your brand guideline into something the AI can read. We’ll often build it as a skill file, a simple markdown file that you plug into your AI tool, so every banner, email draft or product description starts from the same rules.

This matters more as your output grows. When one designer made everything, the brand lived in their head. Now your team, your freelancers and your AI tools are all producing assets, often on the same day. The guideline is how you scale the volume without losing the feel.

Start with the audit. If the side-by-side makes you wince, that’s your case for a guideline, and for fixing the touchpoint closest to the sale first.
