    Why is Google not indexing my pages?

    Check Google Search Console’s Coverage report for specific errors. Common causes include: noindex tags, robots.txt blocking, crawl errors, low-quality or duplicate content, new site without enough authority, or pages requiring JavaScript that Googlebot can’t render. Use the URL Inspection tool to see exactly how Google views your page.

    How do I fix slow page load times?

    Optimize images (compress and use modern formats like WebP), enable browser caching, minify CSS/JavaScript, use a CDN, reduce server response time, eliminate render-blocking resources, and lazy-load below-the-fold content. Use Google PageSpeed Insights to identify specific issues affecting your Core Web Vitals.

    What are Core Web Vitals and why do they matter?

    Core Web Vitals are Google’s metrics for measuring user experience: LCP (Largest Contentful Paint) for loading, FID/INP (Interaction to Next Paint) for interactivity, and CLS (Cumulative Layout Shift) for visual stability. They’re a ranking factor, and good scores improve user experience, which leads to better engagement and conversions.

    How do I fix duplicate content issues?

    Implement canonical tags to specify the preferred version of pages, use 301 redirects for truly duplicate URLs, ensure consistent internal linking (www vs non-www, trailing slashes), use hreflang for international sites, and consolidate similar thin content into comprehensive pages.

    What is mobile-first indexing and how does it affect my site?

    Mobile-first indexing means Google primarily uses the mobile version of your site for ranking and indexing. If your mobile site has less content, different structure, or poor performance compared to desktop, it could hurt your rankings. Ensure responsive design, same content on mobile/desktop, and good mobile page speed.
