Welcome to Arjun Adhikary’s official website! I am an experienced SEO expert based in Bangladesh, and I specialize in helping businesses reach top positions on Google through effective and sustainable strategies. One of the key pillars of search engine optimization is Technical SEO. In this comprehensive guide, I’ll walk you through everything you need to know about technical SEO in 2025, including its definition, importance, key components, and actionable tips to improve your website’s performance and rankings.
What is Technical SEO?
Technical SEO refers to optimizing a website’s infrastructure to ensure search engines like Google can efficiently crawl, index, and rank its content. It does not focus on the content itself but rather on the website’s backend architecture and how easily search engines can access your content.
Technical SEO
Unlike on-page SEO, which involves keyword optimization, and off-page SEO, which deals with backlinks and external signals, technical SEO focuses purely on the technical elements of your website. Think of it as laying a strong foundation for your SEO house. Without it, all other SEO efforts could be in vain.
Why Technical SEO Matters in 2025
With search engines becoming increasingly sophisticated, technical SEO has become more important than ever. Here’s why:
1. Improves Crawlability and Indexing
Search engine bots must be able to access your site to index its content. Technical SEO ensures that your site structure and files like robots.txt and sitemap.xml guide bots correctly.
2. Boosts User Experience (UX)
Sites that load quickly, are mobile-friendly, and error-free offer better UX. Google considers UX a ranking factor, and technical SEO is the key to delivering a seamless experience.
3. Supports Higher Rankings
If your site has crawl errors, broken links, or duplicate content, Google may not rank it well. Technical SEO fixes these issues, thereby improving your visibility.
4. Increases Security and Trust
Secure websites with HTTPS protocols and valid SSL certificates protect users and gain Google’s trust, which positively influences ranking.
5. Future-Proofs Your Site
As algorithms evolve, a technically optimized website is more adaptable and ready to meet new SEO standards without massive overhauls.
Key Components of Technical SEO
1. Website Speed Optimization
Page speed is a confirmed ranking factor. Slow websites lead to higher bounce rates and poor user experience.
How to Improve Speed:
- Compress images using tools like TinyPNG or ShortPixel.
- Use a Content Delivery Network (CDN) to reduce latency.
- Minify CSS, JavaScript, and HTML.
- Leverage browser caching and server-side caching.
- Choose a fast and reliable hosting provider.
2. Mobile Friendliness
With mobile-first indexing, Google predominantly uses the mobile version of content for indexing and ranking.
Tips:
- Use responsive web design.
- Avoid flash elements and intrusive interstitials.
- Make sure buttons and navigation are easy to use on smaller screens.
- Test your site using Google’s Mobile-Friendly Test tool.
3. Secure Your Website with SSL (HTTPS)
Security is a priority for Google. Sites using HTTPS enjoy a ranking boost and instill trust in users.
Steps to Secure Your Site:
- Install an SSL certificate from a trusted provider.
- Ensure all internal links point to HTTPS versions.
- Set up redirects from HTTP to HTTPS.
4. XML Sitemaps
Sitemaps tell search engines about the pages on your site. A well-structured sitemap helps ensure all valuable pages get indexed.
Best Practices:
- Keep it clean—avoid including duplicate or error pages.
- Update it regularly to reflect new content.
- Submit it to Google Search Console.
5. Robots.txt File
This file instructs search engines on which pages to crawl and which to avoid.
Key Tips:
- Don’t accidentally block important pages.
- Use wildcards wisely to block patterns of URLs.
- Always test the file using Google’s Robots.txt Tester.
6. Canonical Tags
Duplicate content can dilute your rankings. Canonical tags specify the preferred version of a page, helping to consolidate ranking signals.
Example:
<link rel="canonical" href="https://example.com/original-page/" />
7. Fixing Crawl Errors
Use tools like Google Search Console to identify and fix crawl errors.
Common Issues:
- 404 Not Found errors
- 301 redirect loops
- Server errors (5xx)
8. Structured Data & Schema Markup
Structured data helps search engines understand your content and can result in rich snippets like star ratings or event details.
How to Use It:
- Use tools like Google’s Structured Data Markup Helper.
- Add schema for articles, products, local businesses, and FAQs.
- Validate your markup using Google’s Rich Results Test.
9. URL Structure Optimization
Clean, descriptive URLs are easier for both users and search engines.
Tips:
- Include your main keyword in the URL.
- Avoid using long strings of numbers.
- Use hyphens instead of underscores.
10. Breadcrumb Navigation
Breadcrumbs improve site hierarchy and help both users and search engines understand site structure.
Benefits:
- Enhances internal linking
- Adds additional links in SERPs
11. Pagination and Infinite Scroll
For sites with lots of content (e.g., blogs, e-commerce), proper pagination ensures all content is crawlable.
Tips:
- Use
rel="next" and rel="prev" tags
- Provide alternate navigation methods like “View All” links
12. Avoid Duplicate Content
Duplicate content confuses search engines and can lead to lower rankings.
Fix It By:
- Using canonical tags
- Setting preferred domain (www vs non-www)
- Avoiding duplicate meta tags
Technical SEO Tools You Should Use
To implement and monitor technical SEO, use the following tools:
- Google Search Console – Crawl errors, sitemap submission, performance tracking
- Screaming Frog – Complete site audits
- Ahrefs & SEMrush – Technical audits, backlink analysis, keyword tracking
- GTmetrix – Website speed analysis
- Google PageSpeed Insights – Specific recommendations for improving page load times
- Google Mobile-Friendly Test – Analyze mobile responsiveness
Common Technical SEO Mistakes to Avoid
- Not setting up redirects properly
- Blocking important pages with robots.txt
- Forgetting to submit XML sitemap
- Not installing SSL
- Slow page load times
- Duplicate content issues
- Ignoring crawl errors in Google Search Console
- Lack of mobile optimization
- Poor internal linking
- Not using structured data
How Technical SEO Affects Rankings
1. Accessibility
Google bots must access your site to index it. Blocked pages or broken links prevent indexing and ranking.
2. Relevance
A well-structured site communicates relevance clearly. Search engines can understand content better, improving ranking potential.
3. Authority
Technical SEO enables fast, error-free browsing, leading to better UX. This in turn increases time on site, shares, and backlinks—signals Google uses for ranking.
Final Words
Technical SEO is not a one-time task—it’s an ongoing process that forms the backbone of your site’s SEO success. By ensuring that your site is technically sound, you build a strong foundation upon which your content and off-page SEO efforts can thrive.
