Service Description for SEO Audit and Technical Fixes for Custom Sites

A custom site can look polished but still underperform in search due to technical friction: pages may be blocked from crawling, canonical signals can conflict, redirects may be misconfigured, or performance issues can prevent full rendering and indexing. Teams often discover these problems only after rankings drop, and fixing them ad hoc risks breaking user flows or reintroducing issues.

DevionixLabs performs a targeted SEO audit and delivers technical fixes designed for custom environments—so you get measurable improvements without destabilizing your product. We start by diagnosing the exact causes behind crawl/indexation and ranking limitations, then implement fixes that align with how your site actually works (routing, templates, rendering, and deployment patterns).

What we deliver:
• Technical SEO audit report with prioritized findings and root-cause analysis
• Crawlability and indexation checks (robots, sitemaps, redirects, status codes)
• Canonical and duplicate-content validation across templates and dynamic pages
• Performance and rendering review (Core Web Vitals, asset strategy, bottlenecks)
• Internal linking and discoverability improvements based on your architecture
• Structured data validation and remediation where relevant
• Fix implementation plan with engineering-ready guidance and QA criteria
• Verification after changes to confirm indexing and crawl behavior

Before vs After Results
BEFORE DEVIONIXLABS:
✗ Search engines struggle to crawl key pages due to routing/redirect issues
✗ Indexation is inconsistent because canonical and duplication signals conflict
✗ Slow performance reduces rendering quality and crawl efficiency
✗ Technical SEO fixes are applied without a prioritized, testable plan
✗ Teams lack post-change verification, so issues recur

AFTER DEVIONIXLABS:
✓ Improved crawl coverage for priority page templates
✓ More consistent indexing outcomes through corrected canonical/redirect logic
✓ Faster page performance that supports better rendering and user engagement
✓ Reduced duplicate-content risk with template-level corrections
✓ Verified fixes with measurable improvements in technical health signals
