In the fast-evolving world of digital marketing, search engine algorithms aren’t what they used to be. Google’s ranking systems have grown more sophisticated, and so must your SEO strategy. While most businesses obsess over keywords and content (which are undoubtedly important), many ignore the silent workhorse of their search visibility
If your website loads slowly, has crawling issues or fails to deliver a secure user experience, even the best-written content won’t get the spotlight it deserves. That’s where technical SEO steps in, acting as the foundation that allows your content to shine and your business to grow.
This guide will walk you through everything you need to know about technical SEO in 2025, the best technical SEO practices, and how to do a technical SEO audit like a pro.
What is Technical SEO?
Technical SEO is the process of optimising a website’s backend infrastructure, such as site speed, crawlability, and security, to help search engines crawl, index, and rank it more effectively.
It focuses on the structural aspects of a website that ensure smooth interaction with search engine bots and provide a better user experience. Unlike content or backlinks, technical SEO focuses on the foundation that enables your website to function reliably and efficiently.
8 Important Parts of Technical SEO Not to Ignore
When it comes to technical SEO, several foundational aspects must be optimised to improve search visibility and user experience:
- Website Speed and Performance
- Mobile-friendliness
- Structured Data (Schema Markup)
- Crawlability and Indexation
- Secure Connections (HTTPS)
- URL Structure and Canonical Tags
- XML Sitemaps and Robots.txt
- Duplicate Content Issues
When these elements are correctly implemented, your site becomes easier for both users and search engines to navigate, ultimately increasing your chances of ranking higher on Google.
Why Is Technical SEO Important?
In 2025, with Google’s ongoing emphasis on user experience and page quality, technical SEO is no longer optional, it’s fundamental. This is a crucial insight that keeps you ahead in the digital marketing game.
Let’s look at some key stats:
- 53% of users abandon a mobile site if it takes more than 3 seconds to load.
- Google’s Core Web Vitals are now confirmed ranking signals.
- According to Backlinko, 94% of top-ranking pages feature an optimised meta tag structure and a mobile-friendly design.
These numbers make it clear. If your site isn’t technically sound, your rankings and leads will suffer.
7 Effective Ways to Improve Your Technical SEO
Mastering the best technical SEO practices can seem daunting, but breaking them down into actionable steps makes it easier.
1. Improve Site Speed and Core Web Vitals
Utilise tools such as Google PageSpeed Insights and Lighthouse to pinpoint performance issues. Compress images, implement lazy loading, and reduce third-party scripts. Aim for:
- Largest Contentful Paint (LCP) under 2.5s
- First Input Delay (FID) under 100ms
- Cumulative Layout Shift (CLS) under 0.1
2. Optimise for Mobile-First Indexing
With mobile-first indexing the norm, your site must perform flawlessly on smaller screens. Use responsive design, readable fonts, and tap-friendly buttons.
3. Use HTTPS and Strengthen Site Security
Secure sites (HTTPS) rank better and build trust with users. If you’re still on HTTP in 2025, you’re already behind.
4. Clean Up Your URL Structure
Short, descriptive URLs help both users and bots. Avoid dynamic parameters when possible. For example:
/services/seo-delhi is better than /services?id=145
5. Implement Structured Data
Schema markup helps search engines understand your content in a contextual manner. It also enhances your listings with rich snippets (stars, reviews, FAQs). Use Google’s Structured Data Testing Tool to validate.
6. Create a Logical Internal Linking Structure
Help bots crawl your site efficiently by connecting related pages. Internal links also help distribute authority and guide users through their journey.
7. Fix Crawl Errors & Broken Links
Use Google Search Console to identify crawl errors, redirect broken links, and keep your sitemap up to date. Submit a clean robots.txt to ensure bots don’t waste time.
Technical SEO Audit Checklist: 4 Key Areas to Review
A technical SEO audit helps identify hidden issues that could impact your rankings and user experience. Here are the top four areas you should always check:
1. Crawl & Indexation Status
Make sure your important pages are crawlable and indexed correctly. Use Google Search Console to identify blocked URLs, crawl errors, or pages marked with the ‘noindex’ tag.
2. Site Speed & Core Web Vitals
Check loading times and performance metrics, such as LCP, FID, and CLS, using PageSpeed Insights or Lighthouse. Fix large images, third-party scripts, or layout shifts.
3. Mobile Usability
Audit your mobile experience using the Mobile-Friendly Test. Look for touch issues, overlapping content, and unreadable text that can hurt rankings.
4. Schema & Structured Data
Ensure your pages use valid schema markup for enhanced visibility in search (e.g., reviews, FAQs, articles). Use the Rich Results Test to verify implementation.
