How to Choose a Web Design Company: 10 Criteria and Scorecard

Choosing a web design company only by portfolio appearance or the initial proposal price hides many of the risks that determine whether the website can be launched and operated safely. A sound decision evaluates discovery, real project evidence, user experience, technical quality, content and SEO preparation, account ownership, testing, support and handover together.

This guide gives you a consistent framework for comparing web design companies. It does not claim to rank a universal “best” provider. It helps you select the right delivery partner for your scope using evidence.

Quick Answer: How Do You Choose a Web Design Company?

1. Write the business outcome and the tasks users must complete.
2. Give every candidate the same requirements brief.
3. Verify comparable live projects and the provider's actual role.
4. Look for scope, exclusions, deliverables and acceptance criteria.
5. Assess accessibility, performance, security and SEO preparation as well as appearance.
6. Clarify ownership of domains, hosting, source code, data and third-party accounts.
7. Separate warranty, maintenance, support and new development.
8. Compare candidates with one scorecard and move critical conditions into the contract.

1. Define the Need Before Looking for a Provider

“We need a modern, fast and mobile-friendly website” is not enough for comparable proposals. Explain why the site is being created or replaced, who will use it, which tasks they must complete and how success will be measured. Pages, content ownership, languages, forms, accounts, payments, CRM or ERP integrations, migration and legal requirements all affect scope.

Use our guide to preparing a website requirements document if you need a starting structure. Giving every candidate the same current brief reduces misleading price differences caused when one provider quotes a few design screens while another includes content, development, migration and testing.

2. Review Portfolios for More Than Appearance

A portfolio should demonstrate work the company performed, not merely display screenshots of recognisable brands. Ask for the live URL, release period, the provider's actual responsibilities and whether it still supports the product. If another team produced the design, software, content or campaign, the boundary should be stated.

Use the reference on desktop and mobile. Can you understand the navigation, find important information, complete forms, recover from errors, read the content and perform essential actions with a keyboard? One polished home page is not evidence that the team can deliver and operate a complete website.

Questions for a reference conversation

• How closely did delivery follow the agreed scope and process?
• How were changes recorded and approved?
• Who completed pre-launch testing and content checks?
• How did the provider handle support after launch?
• Were accounts, source files and documentation handed over?

3. Identify the Delivery Team and Responsibilities

The person presenting the proposal may not be the team delivering the website. Ask who will manage the project, content, interface design, frontend, backend, testing and SEO preparation. One person may cover multiple roles on a small project; responsibility and communication still need to be visible.

Prefer defined decisions and approval points to vague promises of unlimited revision. Discovery, sitemap, wireframes, visual design, development, content entry, testing, acceptance and launch should each have an owner and a deliverable.

4. Look for Scope, Exclusions and Acceptance Criteria

A useful proposal explains what is included, what is excluded and which assumptions support the estimate. Page templates, content ownership, languages, licences, integrations, data migration, imagery, training, testing and launch assistance should be separate items.

Replace “contact form included” with fields, recipients, data storage, spam controls, failure behaviour and a testable success state. Replace “SEO friendly” with crawlable navigation, editable titles and descriptions, canonical and language tags, redirects, sitemap, structured-data responsibility and performance checks.

Use the 12-criterion website proposal scorecard to compare proposal lines consistently.

5. Check Whether Design Decisions Use User Evidence

The company should listen to your organisation, but applying a list of visual preferences is not enough. Audience tasks, content priority and measurement evidence should inform the interface. Sitemaps and wireframes help test information architecture before colour and imagery. Prototype review can use realistic tasks rather than asking only whether stakeholders like the screens.

Accessibility is not a badge added at the end. Contrast, keyboard operation, visible focus, meaningful headings, form labels and error explanations should be addressed through design and development. W3C's Web Content Accessibility Guidelines provide testable success criteria for more accessible web content. (WCAG 2.2)

6. Turn Technical Quality into Testable Deliverables

Ask for measurement methods instead of absolute statements such as “extremely fast”, “fully secure” or “guaranteed rankings”. Performance changes by page type, device, network, third-party code and real-user conditions. The proposal should name representative pages, test environments, issue thresholds and the scope of post-launch monitoring.

Google's Core Web Vitals use LCP, INP and CLS and recommend evaluating the 75th percentile of real page visits. They do not describe every aspect of quality, but they make part of the performance discussion measurable. (Web Vitals)

Security requirements depend on the product. A platform with accounts, personal data, payments or administration carries different risks from a simple information site. The OWASP Application Security Verification Standard offers a basis for structuring web-application security requirements and verification levels. (OWASP ASVS)

7. Clarify Content, SEO and Redirect Responsibilities

A new interface does not repair incomplete content automatically. Decide which existing pages will be retained, updated, consolidated or removed. Each page needs a purpose, topic, expert input, assets and an approval owner.

If URLs change, map old addresses to relevant replacements with 301 redirects. In multilingual projects, map Turkish and English routes separately and test canonicals, hreflang, language switching and sitemaps. Google's SEO Starter Guide describes foundational practices for understandable site structures, useful content and discoverability. (Google SEO Starter Guide)

8. Resolve Code, Data and Account Ownership Before Contracting

The contract should identify the owner and administrator of the domain, DNS, hosting, source repository, database, media, email service, analytics and third-party APIs. Dependence on accounts controlled only by a supplier creates risk during an emergency or provider change.

In Kumsal Ajans's handover process, access to hosting and control panels, domains and DNS, source code, databases, FTP or SSH and third-party services is verified first. Complete backups of site files, databases, media and the current production release are taken before migration. Live migration or extensive intervention does not begin while source code, a database or critical access is missing. After access is complete, the site, forms, email delivery, SSL, DNS, redirects and core functions are checked, and the final transition is confirmed with client approval.

Expected handover items

• Current source code and version history
• Database, media and configuration backups
• Domain, DNS, server and certificate access
• Third-party service, licence and renewal register
• Installation, deployment and rollback documentation
• Administration training and user permissions
• Known issues, test results and open work

9. Separate Maintenance, Warranty and New Development

Warranty explains how defects within the accepted scope are handled under defined conditions. Maintenance may cover updates, backups, monitoring, compatibility or continuity described in a service agreement. New functionality, integrations and scope changes are separate development.

Ask for the support channel, operating hours, priority levels, initial-response target, mitigation process and charging model. “Always available” becomes meaningful only when its boundaries are clear. Assess renewals, licences, hosting, maintenance and future changes alongside the initial investment through a total-cost view.

10. Compare Every Candidate with the Same Scorecard

Adjust weights to the project. Security may carry more weight for accounts and sensitive data; content operations and migration may be more important for a multilingual publishing site. Treat a failed critical ownership or security condition separately even when the total score is high.

Warning Signs

• A fixed package and deadline offered before discovery
• Screenshots without live, verifiable references
• Unconditional ranking, sales or conversion guarantees
• No owner for content, integrations, testing or migration
• Unclear delivery of domain, source code or database
• Critical accounts opened only in the supplier's name
• Warranty, maintenance and new work combined into one vague service
• No separate 301 plan for changed Turkish and English URLs

Conclusion

The right web design company is not necessarily the provider with the most polished presentation or lowest initial amount. It is the partner that turns needs into shared scope, supports decisions with evidence, tests quality and defines ownership from source code to service accounts.

Prepare the requirements brief first, then request written proposals against the same scope. Compare portfolio evidence, team, process, technical quality, content, ownership and total cost with one scorecard. Put critical conditions into the contract and handover list before making the selection.
