If you want your website to rank on Google in 2025, you can’t just focus on great content and backlinks—you also need technical SEO. Think of technical SEO as the foundation of your house: if it’s weak, no matter how beautiful the decor (content) is, your house (website) won’t stand strong.
In this guide, we’ll break down a beginner-friendly technical SEO checklist that covers all the essentials: crawling, indexing, site structure, mobile optimization, Core Web Vitals, schema markup, and more. Follow these steps, and you’ll give search engines (and your visitors) exactly what they need.
What Is Technical SEO?
Technical SEO refers to optimizing your website’s infrastructure so that search engines can crawl, index, and rank it effectively. Unlike content SEO (keywords, blogs) and off-page SEO (backlinks), technical SEO focuses on:
- Website speed and performance
- Crawlability and indexability
- Mobile responsiveness
- Secure connections (HTTPS)
- Structured data and schema markup
- Fixing errors (broken links, redirects, duplicate content)
Without technical SEO, even the best content may never show up in search results.
Technical SEO Checklist for Beginners in 2025
Let’s go step by step.
Make Sure Your Site Is Crawlable
Search engines use bots (crawlers) to discover and understand your pages. If they can’t crawl your site properly, you won’t rank.
Action Steps:
- Check robots.txt file: Ensure you’re not blocking important pages. Example:
User-agent: *
Disallow: /private/
Allow: /
- Submit XML Sitemap: Create and submit via Google Search Console.
- Fix crawl errors: Look for “Coverage” issues in Search Console (404s, blocked pages).
Pro Tip: Use tools like Screaming Frog or Ahrefs Site Audit to detect crawlability problems.
Ensure Proper Indexing
Crawling doesn’t guarantee indexing. Your pages must be added to Google’s index to appear in search results.
Checklist:
- Search for
site:yourdomain.comin Google to see indexed pages. - Avoid noindex tags on important pages.
- Use canonical tags to prevent duplicate content issues.
- Submit URLs manually in Google Search Console if needed.
Example: An e-commerce store had 5,000 products but only 1,200 indexed. After fixing canonical tags and sitemap errors, their indexed pages doubled, boosting traffic.
Switch to HTTPS (If You Haven’t Already)
Security is a ranking factor. Sites without HTTPS show a “Not Secure” warning, which hurts trust and conversions.
What to do:
- Get an SSL certificate (free with Let’s Encrypt).
- Redirect all HTTP pages to HTTPS using 301 redirects.
- Update internal links to HTTPS.
Stat: 95% of first-page results on Google are HTTPS websites (Backlinko).
Improve Site Speed & Core Web Vitals
A slow website frustrates users and lowers rankings. Google measures this with Core Web Vitals:
- LCP (Largest Contentful Paint): <2.5 seconds
- FID (First Input Delay): <100ms
- CLS (Cumulative Layout Shift): <0.1
Optimization Tips:
- Compress images (use WebP/AVIF).
- Use a Content Delivery Network (CDN).
- Minify CSS, JavaScript, and HTML.
- Enable browser caching.
- Use lazy loading for images and videos.
Example: Walmart reduced page load time by 1 second and saw a 2% increase in conversions.
Optimize for Mobile-First Indexing
Google now uses mobile-first indexing, meaning it primarily crawls your mobile site.
Mobile SEO Checklist:
- Responsive design (text and images adjust to screen size).
- Avoid intrusive pop-ups.
- Use large, tappable buttons.
- Test with Google’s Mobile-Friendly Test tool.
Stat: Over 70% of web traffic comes from mobile devices in 2025.
Fix Broken Links & Redirects
Broken links hurt user experience and SEO.
How to Fix:
- Use Screaming Frog or Ahrefs to find 404 errors.
- Set up 301 redirects for moved/removed pages.
- Avoid redirect chains (multiple hops).
Example: A blog fixed 350+ broken links, resulting in a 25% drop in bounce rate.
Use Structured Data (Schema Markup)
Schema helps search engines understand your content better and display rich snippets (stars, FAQs, prices).
Common schema types:
- Article
- Product
- Review
- FAQ
- Local Business
Tools: Use Google’s Rich Results Test to validate schema markup.
Create a Logical Site Structure
A clear hierarchy makes it easier for crawlers (and users) to navigate.
Best Practices:
- Use a flat structure (no page more than 3 clicks deep).
- Group content into categories and subcategories.
- Use breadcrumbs for navigation.
- Implement internal linking to spread authority.
Example: After restructuring its site, an online retailer increased organic traffic by 42% in 4 months.
Optimize URL Structure
Clean, descriptive URLs help both users and search engines.
Good URL:
https://example.com/seo/technical-seo-checklist
Bad URL:
https://example.com/page.php?id=12345
Tips:
- Keep URLs short and keyword-rich.
- Use hyphens (-) instead of underscores (_).
- Avoid unnecessary parameters.
Manage Duplicate Content
Duplicate content confuses search engines and can dilute rankings.
How to Fix:
- Use canonical tags to show the preferred version.
- Set up 301 redirects for duplicates.
- Avoid publishing identical product descriptions.
Pro Tip: If you run an e-commerce store, write unique product descriptions instead of copying from manufacturers.
Monitor Technical SEO with Tools
Staying on top of technical SEO is an ongoing task.
Recommended Tools:
- Google Search Console – Crawl, index, errors.
- Google PageSpeed Insights – Core Web Vitals.
- Screaming Frog – Crawling, broken links, duplicates.
- Semrush / Ahrefs – Site audits, backlink health.
