Briefly, what should you know?
A successful website emerges when the goal, content architecture, measurement and maintenance ownership are clarified before design.
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 should I pay most attention to when building a website? The first thing talked about in the field is usually design; However, the real decisions that determine the fate of the project are purpose definition, information architecture, SEO infrastructure, content strategy and measurement. Design is the image of these decisions; It is not fundamental.
In this article, we review all the steps that should not be skipped when starting a project. It is a control set that will help you create a common language with both the guide and the agencies you receive offers from.
1. Clarify purpose and user action
You should be able to measure the success of the site in a single sentence: “What user action should increase when this site goes live?” The answer might be “filling out a quote form”; It could also be “WhatsApp writing”, “phone call”, “e-commerce sales”. Design and development decisions taken before the purpose is clear create constant revision later on.
2. Skeleton the content before designing
The content architecture (page list, hierarchy of each page, and message flow) should be prepared in writing before the design begins. The design is the visual equivalent of this skeleton; Designing a blank outline and filling it in later is the answer to most projects. is the most expensive mistake.
3. Plan SEO from the beginning
SEO is not just a plugin. URL structure, hierarchy, taxonomy, schema, page speed and internal linking are architectural decisions. If it is set up from scratch, the cost is lower; If added later, it often requires restructuring of the site.
- URL structure should be planned based on language + intent.
- Schema (Article, FAQ, Product, LocalBusiness, etc.) should be integrated into the page templates from the beginning.
- Core Web Vitals goals should be included in the contract.
- Internal link sets should be planned together with the content architecture.
4. Put speed and performance criteria into the contract
As of 2026, Google continues to consider user experience signals as a ranking factor. Concrete target values for LCP, CLS and INP (e.g. LCP < 2.5 sec) must be included in the contract; Pre- and post-publication measurement should be mandatory.
5. Make a security and backup plan
HTTPS, WAF, automatic backup, update discipline and authorization hygiene are essential components for the long life of the site. Rate limiting, bot protection and encryption standards should be asked, especially for form fields and the administration panel.
6. Frame the maintenance agreement in advance
How will your communication with the supplier be after the broadcast? How many hours of maintenance per month? What is the response time for critical errors? If these questions are not tied into the contract, you will negotiate a new offer for every small change.

7. Verify metering setup before release day
- GA4 and GTM installation
- Form submission, phone click, WhatsApp click events
- Conversion goals
- Search Console link and sitemap
- Error tracking (optional but recommended)
8. Source code and access ownership
When the site goes live, you must have access to the hosting, domain name, source code, design files and management panel. If this clause is not clear in the contract, you will encounter a "vendor lock" when you want to work with another company in the future.
9. QA checklist before going live
- Speed test on all pages
- Mobile and tablet view
- Form submission tests and notification emails
- Browser compatibility
- Linkage and indexability check
- SSL and security headers
- Schema validation
- 404 redirects
Don't forget
Getting back the budget spent on the wrong structure is much more expensive than the budget spent on the right structure. Infrastructure choices made in the first 30 days determine the fate of the entire project.
10. Discuss your budget with the scope
Do not separate budget negotiation from scope negotiation. First make a common definition of "what it includes" with the agency, then talk numbers. Price ranges Website Prices 2026 We share it in detail in our article.
Frequently asked questions
Can SEO be added later?

Should content or design come first?
For net transformation and information architecture, the content skeleton must come out first. The design is the visual equivalent of the skeleton.
What tests should be done before going live?
Speed, mobile view, form tracking, indexability, CTA work, schema and security tests.
