What to evaluate in a leading web design company

A top web design company should be more than a visual studio. Evaluate along five pillars: Strategy & UX, SEO expertise, Technical performance, Ongoing marketing capability, and Commercial terms (pricing, contracts, support).

Strategy & conversion focus
Do they ask about your business goals, customers, and conversion funnel before designing? Look for evidence of CRO, clear CTAs, and measuring leads — not just pretty pages.
SEO capability
Check for on-page SEO, schema implementation, local SEO, and a documented process for keyword research and content optimisation.
Performance & accessibility
They should measure page speed, Core Web Vitals, and accessibility. Ask for real test results from live client sites.
Marketing & analytics
Top firms deliver analytics, tracking, and integration with ads/email so you can measure ROI. Reports should be regular and actionable.
Support & update process
How do you request updates? Leading companies offer fast turnaround (minutes to days), transparent SLAs, and predictable pricing for ongoing changes.

SEO capability: proof, process, and outcomes

SEO is often the single biggest determinant of a website's commercial success. When vetting companies, ask for evidence — not promises.

What to ask for

  • Case studies with traffic increases: Request before/after organic traffic and conversion metrics (3–6 months minimum).
  • Keyword research sample: They should show intent-driven keywords mapped to service pages.
  • On-page checklist: Titles, metas, headings, image alt text, internal linking, and canonical tags.
  • Technical SEO proofs: sitemaps, robots.txt, structured data (LocalBusiness schema), and mobile-first indexing readiness.
  • Local SEO plan: For trades and local services, a documented plan for Google Business Profile, citation management, and review strategy is essential.

Red flags

  • No measurable case studies or anonymous screenshots only.
  • Promises of "first page in a week" — SEO is continuous and competitive.
  • No mention of schema, Core Web Vitals, or mobile optimisation.
Minimum deliverables you should get
Keyword map • SEO meta & H tag setup • XML sitemap • Structured data for your business • Mobile-friendly content outlines • Monthly performance report

Design & UX quality: conversion-first design

Design should help users do what you want them to do: request a quote, call, or book. Visuals are important — but conversion elements and clarity matter more.

Clarity of value

Does the homepage quickly answer "what you do", "who you help", and "what to do next" within 5 seconds?

Hierarchy & CTAs

Priority CTAs, contrasting colours, and minimal distractions increase conversion rates. Test placement and wording.

Mobile UX

Menu patterns, tap targets, and condensed content for mobile users are non-negotiable.

Trust signals

Reviews, certifications, clear contact info, and project photos build trust quickly.

Quick test: Ask the vendor to show 3 live client homepages on a phone and explain how those sites convert visitors into customers. If they can't, that's a warning.

Technical performance & reliability

Even beautifully designed sites fail if they are slow, down frequently, or incompatible with browsers and devices. Technical excellence is non-negotiable.

Page speed

Ask for Lighthouse or PageSpeed Insights reports from live client sites. Target: mobile score 80+, LCP under 2.5s, and CLS < 0.1.

Hosting & uptime

Know who hosts the site and SLA for uptime, backups, and incident response. Ask for uptime history for client sites.

Security & privacy

Ensure automatic HTTPS, secure headers, daily backups, and a process for vulnerability patching.

Integrations

Confirm compatibility with tools you use: CRM, booking systems, analytics, ads pixel, email platforms.

Marketing benefits: how the right designer improves ROI

A top web design partner becomes your marketing engine. Look for vendors who build sites that feed into paid media, email, and local discovery.

  • Landing page strategy: Targeted landing pages for ads reduce cost-per-lead and improve Quality Score.
  • Conversion tracking: Accurate event tracking for calls, forms, and bookings is essential to measure ad spend ROI.
  • Content & SEO synergy: Designers who coordinate with content/SEO teams get compound results — higher rankings and better ad performance.
  • Local marketing: Integrated Google Business Profile, review prompts, and location pages increase local visibility.
Example outcome (realistic)
A well-optimised local service site + targeted Google Ads can reduce cost per enquiry by 20–40% and increase monthly enquiries by 25–60% within 2–3 months.

33 Questions to ask leading web design companies

Use these to evaluate capability, transparency, and fit. Ask for specifics and examples — vague answers mean risk.

Strategy

  • What's your discovery process?
  • How do you define target audiences and conversion paths?
  • Can you show a recent audit and action plan?

SEO & content

  • Show SEO case studies with metrics.
  • Do you provide content writing or briefs?
  • How do you handle schema and local SEO?

Tech & performance

  • Who hosts the site and where?
  • What caching and CDN strategies do you use?
  • How do you measure Core Web Vitals?

Support & pricing

  • What's included in ongoing fees?
  • How do I request updates and what's the typical turnaround?
  • Are there long-term contracts or setup fees?

Tip: Ask for references you can call — speak with 2 clients about speed, communication and results.

Red flags & deal breakers

  • No measurable outcomes: If they can't show traffic, leads, or speed metrics, be suspicious.
  • Vendor lock-in: If you can't export your content or move the domain, walk away.
  • Hidden fees: Setup fees, per-change fees, or required add-ons should be transparent up front.
  • Slow response times: If they take a week to reply to basic questions, support will be worse post-launch.
  • No analytics setup: A site without tracking is worthless for optimisation.

Selection checklist (use during evaluation)

  1. Documented discovery and strategy process
  2. SEO case study with % traffic lift
  3. Live examples with speed reports
  4. Hosting/SLA and backup policy
  5. Clear update process and typical turnaround
  6. Transparent pricing (what's included/excluded)
  7. No long-term lock-in or ability to export content
  8. Analytics & conversion tracking in place
  9. Reference checks completed
Pro tip
Score each vendor out of 10 on the checklist. Choose the vendor with the best combination of score, cultural fit, and demonstrable ROI — not the cheapest.

Typical onboarding & realistic timelines

Different vendors have different workflows. Here's a practical timeline so you can set expectations.

Discovery: 1–3 days
Kickoff, goals, audience, and content checklist.
Design & approval: 3–7 days
Homepage and key pages designed, iterated, and signed off.
Build & integrate: 3–10 days
Development, CMS setup, integrations (CRM, forms, analytics).
Launch & QA: 1–3 days
Testing on devices, speed checks, SEO basics, and DNS switch.

Congero example: an AI-driven workflow can produce a live demo site in 60 seconds and a professional launch in 24–48 hours with all hosting, domain, and updates included for a flat monthly price.

Frequently asked questions

How do I compare proposals fairly?
Create a comparison table that lists deliverables (SEO, analytics, hosting, backups, updates, turnaround times) and total first-year cost. Score each vendor on core criteria, not on price alone.
Is it better to pay upfront or monthly?
Monthly subscriptions reduce upfront risk and include updates, hosting and SEO in one predictable fee. Upfront builds give ownership but often add maintenance costs later. Choose based on cashflow and need for flexibility.
How soon will I see results from SEO?
Local SEO and technical fixes can show lifts in weeks; content-driven organic growth typically takes 3–6 months. Paid channels can produce immediate enquiries if tracking and landing pages are set up correctly.
What if I need frequent updates?
Look for providers that include unlimited updates or fast-change SLAs. Congero offers text-in updates via WhatsApp and unlimited changes under a flat monthly plan.
