🧩 The Core Components of Technical SEO

1. Website Crawlability

Ensure search engine bots can access your site
Use robots.txt to guide crawlers
Submit XML sitemaps to Google Search Console and Bing Webmaster Tools

Use noindex tags for pages you don’t want in search
Ensure important pages are indexable
Avoid duplicate content issues with canonical tags

3. Site Architecture

Use a clear, logical structure
Keep important pages within 3 clicks from the homepage
Use breadcrumb navigation

4. Mobile-Friendliness

Google uses mobile-first indexing

Minify CSS, JavaScript
Use a CDN (Content Delivery Network)
