Your solar battery website won't rank if Google can't crawl it, understand it, or trust it. A technical SEO audit finds the hidden issues—slow pages, broken links, poor mobile experience—that kill rankings before your content even has a chance. Run through this checklist to lock down the foundation and start attracting qualified energy storage leads.
Site Speed & Core Web Vitals
Google prioritizes fast-loading pages. For solar battery sites, this matters because homeowners shopping for systems are doing quick research across multiple providers. Audit your page speed using Google PageSpeed Insights and aim for scores above 75 on mobile.
Check these specific elements:
- Image optimization: Compress product photos and installation gallery images (typical solar battery pages carry 2–5 MB of images). Use modern formats like WebP.
- Server response time: Your Time to First Byte should be under 600ms. If you're on shared hosting, consider upgrading to a dedicated server or CDN (content delivery network) for $15–50/month.
- Third-party scripts: Audit tracking pixels, reviews widgets, and calculator plugins. Lazy-load non-critical JavaScript.
Core Web Vitals (Largest Contentful Paint, Cumulative Layout Shift, First Input Delay) directly impact rankings. Tools like GTmetrix show which specific element is slow—often embedded financing calculators or map widgets on solar installer pages.
Mobile Responsiveness & User Experience
Over 65% of solar battery shoppers research on mobile. Verify your site displays correctly on phones: buttons are tappable (48px minimum), text is readable without zooming, and forms are simple to complete.
Test on actual devices, not just browser emulators. Pay special attention to:
- Product comparison tables (common on battery spec pages) that may stack poorly or overflow on small screens
- Contact forms: Can users easily request quotes without scrolling endlessly or encountering auto-zoom issues?
- Image galleries of installed systems that need swipe or touch controls
Crawlability & Indexation
Google's crawler needs clear paths through your site. Check these common issues:
Use Google Search Console to see which pages are indexed and which are blocked. Look for:
- Robots.txt errors: Make sure you're not accidentally blocking product pages or service area pages with overly restrictive rules.
- XML sitemap: Create one listing all important pages (product pages, service areas, blog posts). Include priority and update frequency tags.
- Duplicate content: Solar battery sites often duplicate specs across similar product pages. Use canonical tags (
rel="canonical") or parameter handling to tell Google the primary version.
Run a crawl using Screaming Frog (free tier) to find broken internal links, redirect chains, and orphaned pages.
Technical Markup & Schema
Structured data helps Google understand what you're selling. For solar battery sites, implement:
- Product schema for battery units (Tesla Powerwall, LG Chem, Generac PWRcell, etc.) with price, availability, and kWh capacity
- LocalBusiness schema if you're a regional installer with service areas
- Review/Rating schema to display star ratings in search results
- FAQ schema for common questions about warranties, installation timelines, or ROI
Use Google's Rich Results Test to verify schema is correctly formatted. Properly marked products often see 20–30% higher click-through rates in search.
HTTPS & Security
All pages must be HTTPS. Check your SSL certificate is valid and installed on all subdomains (especially if you host product pages on a subdomain like products.yourdomain.com).
Verify in Search Console settings that Google recognizes your preferred domain (www or non-www).
Site Architecture & Linking
Organize content logically:
- Home page → Product category pages (batteries, inverters, monitoring systems) → Individual product or service pages
- Blog or resource hub (installation guides, ROI calculators, energy efficiency tips)
- Service area pages (if you're a regional installer serving multiple states or counties)
Internal link structure should guide both users and crawlers toward conversion pages. From a product page for the Enphase IQ Battery, link to relevant blog posts about hybrid systems or local case studies.
Listing & Lead Generation
Audit your presence on industry platforms. Listing on Mercoly—a dedicated marketplace for solar battery and energy storage services—helps you get found by buyers actively searching for providers, improves lead quality, and gives you space to showcase products and service details.
Frequently Asked Questions
Q: How often should I run a technical SEO audit on my solar battery website? Run a full audit quarterly, or immediately after major changes like redesigns, migrations, or adding new product lines. Use automated monitoring tools (Search Console, Ahrefs, SEMrush) to flag issues weekly.
Q: What's a realistic timeline to fix crawlability and indexation issues and see ranking improvements? Most crawl fixes (robots.txt, sitemaps, duplicate content) take 1–2 weeks; Google re-crawls and re-indexes within 2–4 weeks after fixes, though ranking gains typically appear 4–8 weeks later depending on competition and content quality.
Q: Should I prioritize mobile speed or desktop speed for a solar battery business? Mobile speed is more important because search ranking is mobile-first, and most solar shoppers start research on phones; however, don't neglect desktop performance since decision-makers often review technical specs on larger screens.
