Many websites are designed the wrong way around. A group of people decide on the colors, fonts, and layout, then the marketing team is left to do their best with it. It should be the other way around. The design should be based on your marketing aims, or you could have a beautiful website that brings in no leads.
Start with the number, not the palette
Before you open a design tool, select one or two marketing KPIs that you are responsible for. Signups. Qualified leads. Direct sales. Anything with a number associated with it.
This is important as it will alter every decision that follows. A hero image selected to “look premium” is a guess. A hero section created to guide visitors towards an action you want them to take is a test that you can measure. Once you’ve announced the KPI, you have a sieve for every color, layout, and copy decision that comes next. Does this help someone take the action we care about, or does it just look nice? If a design element can’t answer that question, it’s decoration, and decoration is overhead you’re paying for twice – once to build it, and once in lost conversions.
Build pages around the funnel, not the sitemap
Most homepages end up looking like a table of contents: about us, services, testimonials, contact. That’s a filing system, not a sales tool.
Instead, build key pages around where a visitor actually is in the buying process. A person landing on your site for the first time is in an awareness stage. They need context, not a hard pitch. Someone who’s read three blog posts and come back twice is in consideration. They need proof and detail. Someone clicking a “pricing” link from a bottom-of-funnel ad is ready to convert and just needs a clear path to do it.
Each page should have one dominant call-to-action) tied to that stage, not five competing buttons fighting for the same click. A visitor who’s never heard of you doesn’t need a “Book a Demo” button shoved in their face. They need something lower-commitment – a guide, a case study, an email signup – that matches their actual intent. Match the ask to the stage, or you’ll bleed traffic that was never going to convert on a first visit anyway.
Treat speed and mobile layout as design work
Here is a fact that would hopefully influence how you start briefing every project: Over half of the mobile users leave a page if it doesn’t load within three seconds (Google). This is not an issue that the developer will solve once the site is live. This is an issue with the design that’s decided the moment someone decides to go with a heavy hero video or an image carousel.
Page load speed and mobile optimization need to be part of the design brief from day one, not an afterthought slapped on during QA. A beautiful desktop version that renders on a phone as unreadable gibberish is actively wasting your ad budget. You are funneling money to attract people to a page and then funneling most of them straight out the exit before they even see your message.
Keep the ad and the landing page speaking the same language
If someone clicks on an ad that promises a specific offer and then lands on a page with different headline copy, different images, and a vague call-to-action, you’ve broken their train of thought. That mismatch – marketers call it message match – is one of the quietest conversion killers out there.
The solution is simple: echo the headline language, imagery, and offer from the ad or email directly into the landing page. No surprises, no re-explaining. The new arrival should feel as though they landed exactly where the ad promised, not somewhere in the vicinity.
This is where the division between “design” and “marketing” hurts the most. Design-only companies create what looks good. Marketing-only groups write what sells but have no control over the page it lives on. An agency that marries web design and digital marketing strategy, like Zach Sean Web Design, eliminates that divide by designing pages with the campaign already built into the layout instead of adding it as an extra after the fact.
Wire the design to your data, not just your eyes
A webpage may appear to be converting well, but if you’re not tracking anything, it’s still a mystery box. Be sure to connect everything to GA4 or your preferred goal-tracking system before your site goes live. This includes actions that have a real impact, such as form submissions, button clicks, or scroll depth on important sections. If you don’t measure success, how will you repeat it?
After you set up tracking, view any design choice as something you can test. A/B test the location of buttons, how the headlines are worded, and even the sequence of your proof points. Let the numbers guide you where your gut isn’t sure.
Let trust signals do real work
Testimonials, case studies, and verifiable results shouldn’t sit in a forgotten footer section nobody scrolls to. They’re doing the credibility work that your marketing copy can’t do alone – a visitor believes a peer’s story faster than they believe your own claims. Weave them into the page near the CTAs they’re meant to support, not as an afterthought at the bottom.
A website that looks good but doesn’t move people toward a defined outcome isn’t a marketing asset. It’s a brochure with better fonts. Build from
