Start with the outcome, not the homepage mock-up
Before you compare portfolios, write down what the website must achieve: more qualified enquiries, online bookings, clearer credibility for tenders, or support for paid ads. A strong UK web design agency will ask about that goal in the first conversation. If they jump straight to colours and animations, they are designing output — not outcomes.
Share constraints honestly: budget band, timeline, who will update content, and whether you need a CMS. Clarity here saves expensive change requests later.
What a good proposal should include
Expect a written scope covering pages or templates, responsive design, accessibility basics, technical SEO (titles, headings, sitemap, Core Web Vitals practices), analytics setup, and who owns the domain and hosting. Ask how content will be handled — will you supply copy, or do they help structure it?
Be wary of vague packages that promise “SEO included” without saying what that means. On-page technical hygiene is different from ongoing content and link-building work.
Red flags
Guaranteed first-page Google rankings, refusal to put scope in writing, lock-in that keeps your domain or CMS login with the agency, and designs that ignore mobile. Also treat “we’ll do everything for a tiny monthly fee” with caution — something is usually cut: strategy, testing, or aftercare.
Ask for two or three relevant examples and what changed for those clients after launch. Case studies with only pretty screenshots are weaker than stories about leads or conversions.
How LeadGuideAi approaches website projects
We start with Discover and Strategise — goals, audience and structure — then design and build with regular reviews. Technical SEO foundations and analytics go in before launch, and you keep control of your accounts. If you also need ads or an AI chatbot, we plan them so the site and campaigns support each other.
