What Is Technical SEO?
Technical SEO is the process of optimizing your website so search engines can crawl, index, and understand your content. It's the foundation that everything else builds on.
Think of it this way: content is what you say, on-page SEO is how you say it, and technical SEO is whether search engines can even hear you.
The Key Components
1. Site Speed
Google uses Core Web Vitals as ranking signals. Slow sites rank lower and have higher bounce rates.
Key metrics:
- LCP (Largest Contentful Paint): Under 2.5 seconds
- FID (First Input Delay): Under 100 milliseconds
- CLS (Cumulative Layout Shift): Under 0.1
How to improve:
- Compress and optimize images (WebP format)
- Minify CSS and JavaScript
- Use a CDN (Cloudflare Pages includes this)
- Enable browser caching
- Defer non-critical JavaScript
2. Crawlability
If Google can't crawl your pages, they can't rank.
Checklist:
- Submit XML sitemap to Google Search Console
- Fix broken links (404 errors)
- Use clean URL structures (/services/plumbing not /page?id=123)
- Implement proper redirects for moved pages
- Use robots.txt correctly (don't block important pages)
3. Indexability
Crawlable doesn't mean indexable. Make sure Google can add your pages to its index.
- Use canonical URLs to avoid duplicate content
- Add noindex only to pages you don't want ranked (thank you pages, etc.)
- Ensure important pages aren't blocked by robots.txt
- Use proper HTTP status codes (200 for live pages, 301 for redirects)
4. Structured Data (Schema Markup)
Schema helps Google understand your content and can earn rich snippets in search results.
Essential schema types for service businesses:
- LocalBusiness — Your business name, address, phone, hours
- Service — Each service you offer with descriptions
- FAQPage — Questions and answers, used only when current Google guidelines make it appropriate
- Review/AggregateRating — Star ratings in search results
- BreadcrumbList — Site navigation structure
5. Mobile-First Indexing
Google primarily uses the mobile version of your site for ranking. If your mobile experience is poor, your rankings will suffer.
- Responsive design (not separate mobile site)
- Tap-friendly navigation
- Readable text without zooming
- Fast mobile load times
6. HTTPS Security
HTTPS is a confirmed ranking signal. All modern sites should use it.
- Cloudflare Pages provides free SSL
- Ensure all internal links use HTTPS
- Set up proper HTTP → HTTPS redirects

Why Technical SEO Matters for Local Service Businesses
Most local service business websites have terrible technical SEO. This is your competitive advantage. If your site is faster, more crawlable, and better structured than your competitors, you'll rank higher -- even with less content.
