ZenCoder + Landing Page / Marketing Site

Built a landing page / marketing site with ZenCoder?
We'll make it production-ready.

Landing pages are your first impression. Speed, SEO, and conversion optimization matter more here than anywhere else — a slow landing page or broken form directly costs you customers. AI tools build visually appealing pages, but they often miss the technical details that determine whether your page ranks, loads fast, and converts visitors.

Landing Page / Marketing Site challenges in ZenCoder apps

Building a landing page / marketing site with ZenCoder is a great start — but these challenges need attention before launch.

Page speed

Landing pages must load in under 2 seconds. AI tools generate bloated CSS, unoptimized images, and unnecessary JavaScript that slow loading. A 1-second delay in load time reduces conversions by 7%.

SEO fundamentals

Missing meta descriptions, incorrect heading hierarchy, no Open Graph tags, no structured data, and no sitemap. AI tools build the visible content but skip the invisible SEO infrastructure.

Form handling

Your contact form, waitlist signup, or demo request form must work flawlessly. AI-generated forms often lack validation, error messages, success confirmations, and backend integration.

Mobile responsiveness

Over 60% of traffic is mobile. AI-generated layouts sometimes break on small screens — overlapping elements, unreadable text, and inaccessible buttons. Every pixel matters for conversion.

Analytics and tracking

You need to know where visitors come from, what they click, and where they drop off. AI tools don't set up analytics, conversion tracking, or UTM parameter handling.

Common ZenCoder issues we fix

Beyond landing page / marketing site-specific issues, these are ZenCoder patterns we commonly fix.

highSecurity

Automated reviews miss context-specific security requirements

ZenCoder's automated code reviews apply generic security heuristics. They can miss security risks specific to your domain — healthcare data handling, financial regulations, or multi-tenant isolation requirements.

highCode Quality

Generated implementations follow generic patterns, not project conventions

ZenCoder implements features using widely-used patterns from its training rather than the specific conventions, abstractions, and service layers established in your codebase.

mediumBugs

Refactored code may break runtime behavior

Automated refactoring changes function signatures, variable names, and module boundaries. Without comprehensive test coverage, these changes can introduce regressions that aren't caught until production.

mediumBugs

Review feedback applied without full context

When ZenCoder applies code review suggestions autonomously, it can address the feedback literally without considering the broader implications of the change on related modules.
