Building a Consistent Illustration Style for Client Work

Start With the Job Your Visitor Is Trying to Do
Most website projects begin with a mood board and a font pairing. That is the fun part, and it matters, but it will not pay your invoice. Before you open your design tool, write down the single task each page needs to support. A service page exists so someone can understand what you offer and get in touch. A portfolio page exists so someone can browse your work and decide you are credible. A pricing page exists so someone can pick a package without emailing you first.
When you can name the job in one sentence, every layout decision has a test to pass. Does this element help the visitor complete the job, or does it just fill space? That question will save you from the common trap of designing a page that looks impressive in a screenshot but leaves visitors scrolling in circles, unsure where to click.
Write the job at the top of your file. Refer to it when you are tempted to add a carousel nobody asked for.
Build a Hierarchy Before You Build a Layout
Visual hierarchy is simply the order in which the eye lands on things. If everything shouts, nothing is heard. Decide on three levels and stick to them:
- Primary: the page headline and the one main action. Biggest type, strongest contrast.
- Secondary: section headings, subheadings and supporting buttons.
- Tertiary: body copy, captions, labels and metadata.
Limit yourself to two or three type sizes for headings and one for body text. Use weight and colour to create separation rather than adding more sizes. A 32px heading next to a 24px heading next to an 18px heading reads as clutter; a 32px heading, a 20px subheading and a 17px paragraph reads as order.
Contrast does the heavy lifting. If your primary button sits on a light background in a pale colour, it is not a primary button, it is decoration. Give it enough saturation and size that it is the most obvious thing on the screen after the headline.
Use Layout to Steer the Eye
Visitors do not read websites, they scan them. In the UK and across most Western markets, eyes tend to travel in an F or Z pattern: across the top, down the left, across again. Design with that in mind rather than against it.
Practical moves that work on almost any site:
- Keep the primary action above the fold on desktop and mobile. If someone has to scroll to find out how to contact you, you have already lost a share of them.
- Left-align body copy. Centred paragraphs longer than two lines are harder to read and weaken the sense of structure.
- Use a single-column layout for long text and reserve multi-column grids for cards, services or portfolio thumbnails.
- Give elements room to breathe. Generous whitespace signals importance; cramped content signals noise.
- Repeat your call to action at natural pauses: after a benefits section, after testimonials, and at the foot of the page.
Cards are your friend for service lists and case studies. A consistent card with an image, a short heading, two lines of copy and a clear link gives the eye a repeatable pattern to follow down the page.
Write Calls to Action That Earn the Click
The wording of your button matters more than its colour. "Submit" tells the visitor nothing. "Get a quote", "Book a 20-minute call" or "See my packaging work" tells them exactly what happens next.
A few rules worth applying to every client project:
- Use first person where it fits. "Start my project" often outperforms "Start your project" because it feels like the visitor's own thought.
- Front-load the verb. "Download the rate card" beats "The rate card can be downloaded here".
- Reduce perceived risk. Add a line underneath such as "No obligation, reply within one working day" if that is genuinely true.
- One primary action per screen. Secondary actions should be visually quieter, usually a text link or an outlined button.
Make buttons look like buttons. A rectangle with padding, a clear label and a hover or focus state removes all doubt. Tap targets on mobile should be at least 44 pixels tall, with a little space around them so thumbs do not hit the wrong thing.
Test the Design Against Real Behaviour
You do not need a research budget to catch the obvious problems. Print the page, or shrink it to a phone width, and ask three questions. Can I tell what this business does within five seconds? Can I see where to click without hunting? Does the page work if images fail to load?
Then run a quick five-second test with a friend or a fellow freelancer. Show them the homepage for five seconds, hide it, and ask what they remember. If they cannot recall the offer or the next step, your hierarchy needs work, not your colour palette.
Finally, check the small things that quietly cost conversions: form fields with clear labels and sensible error messages, a visible focus state for keyboard users, alt text that describes the image rather than the file name, and a contact route that does not depend on a single social media inbox. Build those habits into your process and you will deliver sites that do not just look considered, but quietly guide every visitor towards the action you designed for.
