What is Technical SEO? (Definition)
- Technical SEO refers to optimizing your website's technical aspects so Google can easily crawl, understand, and index your pages. It's the 'behind-the-scenes' work that makes everything else possible.
- Think of it like a car: You can have a beautiful car with amazing features (content), but if the engine doesn't work (technical SEO), you won't go anywhere.
- The Good News: Most technical SEO issues can be fixed with free tools, and you only need to fix them once. After that, they keep working for you forever.
Website Speed: The Silent Ranking Killer
- Why Speed Matters: 53% of mobile users leave a website if it takes more than 3 seconds to load. Google knows this, so slow websites rank lower.
- How to Test Speed: Go to PageSpeed Insights (pagespeed.web.dev) and enter any website URL. You'll get a score from 0-100.
- Target Scores: Mobile: 60+ (Good), 80+ (Excellent) | Desktop: 80+ (Good), 90+ (Excellent)
- Common Speed Problems and Fixes:
- • Large images → Compress images using tools like TinyPNG or Squoosh
- • Too many plugins → Remove unused plugins (WordPress sites)
- • No caching → Enable browser caching so returning visitors load faster
- • Slow hosting → Consider upgrading to better hosting (Cloudways, SiteGround)
- Pro Tip: Even improving speed by 1 second can increase conversions by 7%.
Mobile-First Indexing
- What is Mobile-First Indexing? Google now uses the MOBILE version of your website to determine rankings, even for desktop searches. If your mobile site is broken, your rankings suffer everywhere.
- How to Check Mobile-Friendliness: Use Google's Mobile-Friendly Test (search.google.com/test/mobile-friendly).
- Mobile Optimization Checklist:
- • Text is readable without zooming (minimum 16px font size)
- • Buttons and links are easy to tap (not too small, not too close together)
- • No horizontal scrolling required
- • Images resize properly on smaller screens
- • Pop-ups don't block the entire screen on mobile
- Reality Check: Over 60% of all Google searches now happen on mobile devices. If your site isn't mobile-friendly, you're invisible to most users.
Google Search Console: Your SEO Dashboard
- What is Google Search Console? A free tool from Google that shows you exactly how Google sees your website. It's essential for any serious SEO work.
- How to Set Up Google Search Console:
- Step 1: Go to search.google.com/search-console and sign in with Google.
- Step 2: Click 'Add Property' and enter your website URL.
- Step 3: Verify ownership (HTML file upload, DNS record, or Google Analytics).
- Step 4: Wait 24-48 hours for data to start appearing.
- What You Can See in Search Console:
- • Which keywords your site ranks for and their positions
- • How many clicks and impressions you get from Google
- • Crawl errors preventing pages from being indexed
- • Mobile usability issues
- • Security issues or manual penalties
Sitemaps and robots.txt Explained
- What is a Sitemap? An XML file that lists all the important pages on your website. It helps Google find and crawl all your content efficiently.
- How to Create a Sitemap: Most website builders (WordPress, Wix, Shopify) create sitemaps automatically. Usually located at: yoursite.com/sitemap.xml
- How to Submit Your Sitemap: In Google Search Console → Sitemaps → Enter your sitemap URL → Submit.
- What is robots.txt? A text file that tells Google which pages to crawl and which to ignore. Located at: yoursite.com/robots.txt
- Common robots.txt Rules:
- • Allow all: User-agent: * Allow: /
- • Block a folder: User-agent: * Disallow: /private/
- Warning: A wrong robots.txt setting can accidentally hide your entire website from Google. Always double-check!
Core Web Vitals: Google's Performance Metrics
- What are Core Web Vitals? Three specific metrics Google uses to measure user experience on your website. They officially affect rankings.
- 1. LCP (Largest Contentful Paint): How fast the main content loads. Target: Under 2.5 seconds.
- 2. INP (Interaction to Next Paint): How quickly the page responds when users click. Target: Under 200 milliseconds.
- 3. CLS (Cumulative Layout Shift): How stable the page is while loading (elements shouldn't jump around). Target: Under 0.1.
- How to Check Core Web Vitals: PageSpeed Insights shows these metrics for any URL. Also viewable in Google Search Console under 'Core Web Vitals' report.
- Why It Matters: Google has stated that Core Web Vitals are now a ranking factor. Sites that pass all three metrics get a small but meaningful ranking boost.
