Case Details

Industry Background

Core Challenges

The client's website had multiple technical and service issues:

Outdated Tech Stack: Traditional jQuery + Table layout with severe code redundancy and slow loading
Extremely Low Crawl Rate: Baidu crawl rate was only 12%, many core pages were not indexed
Poor Rankings: All 12 core product keywords ranked beyond page 5 on Baidu
Low Inquiry Conversion: Monthly inquiries under 15, far below industry average
Broken Mobile Experience: Lighthouse mobile score was only 28, almost zero mobile traffic

"Our product quality leads the industry, but our brand was hard to find on Baidu, let alone product keywords — the website became our biggest weakness."

Optimization Strategy

1. Complete Architecture Migration

Migrated from traditional jQuery+Table to Next.js SSR architecture, fundamentally solving performance and accessibility:

SSR ensures Baidu crawlers get complete HTML content
Component-based development improves maintainability
Dynamic routing + auto sitemap ensures all pages are discoverable

2. Baidu SEO Deep Optimization

Targeted optimization for Baidu's search algorithm:

URL Restructuring: Converted dynamic parameter URLs to static semantic URLs
Meta Information System: Independent Title/Description/Keywords for each product page
Internal Link Network: Three-tier structure (category → product → application scenario)
Baidu Webmaster Tools: Auto push, Sitemap submission, broken link detection
Mobile Optimization: Full responsive layout + touch optimization

3. Content System Restructuring

Content Type	Quantity	Goal
Product Pages	120+	Cover all product lines, independent SEO metadata per page
Industry Solutions	15	Long-tail keyword matrix around application scenarios
Technical Whitepapers	8	Build industry authority, acquire high-value backlinks
Client Cases	20+	Improve conversion through real cases

4. Core Web Vitals Optimization

WebP image conversion + lazy loading, reducing initial load by 72%
Critical CSS inline, non-critical CSS async loading
JavaScript code splitting + Tree Shaking
CDN + Brotli compression

Results

After 4 months of systematic optimization:

Metric	Before	After	Improvement
Baidu Crawl Rate	12%	89%	+642%
Top 5 Core Keywords	0	12	12x
Monthly Inquiries	<15	160+	+967%
Lighthouse Mobile	28	94	+236%
Page Load Speed	6.5s	1.1s	-83%
Monthly Organic Traffic	800+	15,000+	+1,775%

Client Feedback

"The rebuilt website feels like a product from a different era. Baidu indexing and rankings improved dramatically, and our sales team says customers now find us on the first page when searching for products — giving them much more confidence in client meetings."
