Briefly, what should you know?
The right agency shouldn't just show beautiful screens; It should explain how it discovered the problem, how it will measure success, and post-delivery responsibility.
Who is this guide for?
- Businesses planning to invest in new websites
- Decision makers comparing agency offers
- Teams that cannot receive requests from their current website
- Brands that want to rebuild their SEO and content infrastructure
We prepared this guide based on Codeexia's project experience, official sources and real questions that are repeated in bid negotiations. It states the variable fees and technical conditions with its sources; We do not present project estimates as a final offer.
What criteria should I look for when choosing a web design agency? The answer to this question goes far beyond the beautiful visuals seen in the portfolio: the agency's process maturity, its view of the SEO infrastructure, its justification in technology choices, its maintenance model, communication quality and contract discipline; are the real factors that determine whether your project will be successful or not. There are many agencies that can create beautiful designs; However, these 7-8 are the ones that can add value to your business.
In this article, we outline 15 critical questions you should ask the agency, the intention behind each question, and what you should take away from the answer you receive. The list below turns a process in which you meet with three separate agencies into an objective, decisionable framework.
Things to ask before the offer meeting
1. What projects have they done in your sector / of similar size?
Access the live links of the projects in the portfolio. Check the page structure, speed, SEO signals (meta fields, schema, URL structure). An agency that has done similar work in your industry will produce value for you much faster at the brief stage.
2. How do they manage the design process?
In professional agencies, the process is clearly defined: discovery → information architecture → wireframe → visual design → prototype → development → QA → release → improvement. Projects "successful" by an agency that cannot explain the process clearly are often successful by chance.
3. What questions do they ask before the brief?
Does he try to understand your business, target audience, competitors and conversion goals before making the offer? The agency that bids without question is basing the scope on an estimate.
4. How do they define SEO?
The answer “We enter the meta title, SEO is included” is insufficient. Real SEO; It covers information architecture, URL hierarchy, schema, Core Web Vitals and internal link plan. An agency that sees SEO as an "architectural decision" can produce long-term value for you in this regard.
5. Are Core Web Vitals goals written into the contract?
If concrete targets such as LCP < 2.5 sec, CLS < 0.1, INP < 200 ms are not given, performance is not a promise, but a chance.
6. Who will produce the content?
Do you or the agency do the copywriting, visual and case preparation? The exact answer to this question directly affects the release date and total cost.
7. What CMS/technology do they use and why?
WordPress, headless CMS, custom-developed framework — they all have their place. But the agency must be able to explain why it is making this choice. The “we always do it this way” response is a red flag.
Contract and commercial terms
8. How is source code and access ownership included in the contract?
It should be in writing whether you will receive the post-release code and access. Without this clause you are locked into the agency.
9. At what stage and how many are the revision rights?
How many revisions are involved in the wireframe, visual design and development phases? Is it priced by the hour or by the item?
10. Is the payment plan linked to phases?
Phased payment such as 30% initial + 30% design approval + 30% development + 10% publication is a professional approach that protects both parties. “They want it all in advance” is a rejection flag.
11. How is the delivery time guaranteed?
What will happen with the delay? Is there a penalty clause, are the terms of extension of time written? The health of the commercial relationship is visible in these articles.
Post-release expectations
12. What is the scope of the care package?
How many hours per month, on what subjects? Are updates, security, performance monitoring, minor development included? What is the response time and resolution time SLA?
13. Will they provide measurement and reporting?
Will GA4, Search Console and form/CTA event tracking be installed? Will he report regularly in the first 3-6 months? This area is the root of your site optimization.
14. What will be delivered to you when the project is completed?
- Source code and repo access
- Design files (Figma, XD etc.)
- Admin panel information and roles
- Domain/hosting panel access
- Measurement accounts access
- User guide / video documentation
15. What will be the communication channel and response time?
Slack, WhatsApp, email or project management tool? Will a single person or a team respond? Is the response time 4 hours or 24 hours? These details determine the stress level of the project.
Agency evaluation matrix
When you interview three agencies, compare the answers in one table. Before the numbers, you see scope and process maturity.
| Criterion | Agency A | Agency B | Agency C |
|---|---|---|---|
| Similar work portfolio | ✓ / ✗ | ✓ / ✗ | ✓ / ✗ |
| Process description clarity | 1-5 | 1-5 | 1-5 |
| SEO infrastructure scope | 1-5 | 1-5 | 1-5 |
| Core Web Vitals target | Yes/No | Yes/No | Yes/No |
| Source code ownership | Yes/No | Yes/No | Yes/No |
| Care package transparency | 1-5 | 1-5 | 1-5 |
| Communication quality | 1-5 | 1-5 | 1-5 |
| Price | TL | TL | TL |
6 red flags you need to avoid
- Scope is not written into the contract
- Source code delivery is uncertain or “you won't receive post-release files”
- Portfolio links do not work or the agency's own site is slow/without SEO
- Extremely low price + extremely short delivery
- Communication with a single person and no backup
- Vague answers like "We'll do it bro, don't worry"
Practical advice
Process, not portfolio, scope, not price, infrastructure, not design, are decisive. In interviews, “how are you doing?” The quality of the answer to the question is a preview of the quality you will receive throughout the project.
Frequently asked questions
Are a web design agency and a software company the same thing?
No. The web design agency focuses on visual and user experience; The software company dominates infrastructure, integration and custom development. Advanced projects require both competencies.
Should I choose an agency that has a nice portfolio but no references?
Live links of the portfolio should be verified and a reference meeting should be held with at least one customer.
Small agency or big agency?
It depends on the project size. Small teams are fast and personal; Large agencies are better suited for complex integration projects.
Should I work with a freelancer or an agency?
A freelancer may be suitable for one-page landings or small jobs; However, the agency is a more reliable choice in projects that require sustainable maintenance, SLA and team capacity.
