- HTTPS redirection: Set up a redirection from the “http” version of your site to “https” to make sure everyone is using the secure version.
Fix Broken Links and Redirect Chains
Broken links and redirect chains can hurt your site’s usability and rankings.
- 404 error fixes: Regularly check for and fix any broken links that lead to a 404 error page.
- 301 vs 302 redirects: Use a 301 redirect for permanent changes and a 302 redirect for temporary ones to guide search engines properly.
Optimize Site Architecture and URL Structure
Your website should have a simple structure that’s easy for both users and search engines to follow.
- Flat hierarchy: Keep your site structure simple with a clear path to the most important pages, requiring minimal clicks.
- Clean URLs with keywords: Use simple, easy-to-read URLs that include relevant keywords, so both users and search engines can understand what the page is about.
Implement Structured Data and Schema Markup
Adding structured data helps search engines better understand your content, which can lead to better visibility in search results.
- Rich snippets: Use schema markup to show extra information like ratings, reviews, or product prices directly in search results.
- Product, FAQ, and How To schema: Mark up pages like product listings, FAQs, and how-to guides to improve their appearance in search results.
Canonicalization and Duplicate Content Management
Managing duplicate content is essential for good SEO.
- Canonical tags: Use these tags to tell search engines which version of a page is the main one when similar content exists across different URLs.
- URL parameter handling: Handle URL parameters properly to avoid content duplication, which can confuse search engines.
Optimize Crawl Budget and Reduce Waste

- Noindex low-value pages: Mark pages with little SEO value, like login forms or thank-you pages, as “noindex” to save your crawl budget.
- Paginated content strategy: Use proper pagination for long lists of content, like blog posts or product pages, to help search engines index them effectively.
Set Up and Monitor Google Search Console
Google Search Console is a powerful tool for tracking your site’s performance.
- Coverage report: Check for indexing issues and make sure the important pages are being crawled.
- Enhancements report: Track the status of your site’s Core Web Vitals and other performance indicators.
- Core Web Vitals tracking: Keep an eye on your site’s user experience scores to ensure smooth performance for visitors.
Mobile Optimization and Responsive Design
With more people using smartphones to browse the internet, making sure your website works well on mobile devices is very important. Search engines like Google now focus on how mobile-friendly a website is, which means it’s essential to have a website that looks and works great on all types of devices.
Mobile-First Indexing:
Mobile-first indexing means Google looks at the mobile version of your website first to decide how well it should rank in search results.
Since most people browse the internet on their phones, Google gives priority to mobile-friendly sites. If your site isn’t optimized for mobile, it could negatively affect your rankings and make your site harder to find.
Common Mobile SEO Issues and Fixes
There are a few common mobile SEO problems that can hurt your site’s performance, but most of them are easy to fix.
- Slow loading times: If your pages take too long to load, people will leave before they even see your content. To fix this, compress images, minimize file sizes, and use caching to speed things up.
- Touchscreen usability: Links and buttons should be easy to tap without zooming in. Make sure buttons are large enough and spaced properly for mobile users.
- Unresponsive design: If your website doesn’t adjust to different screen sizes, it will be hard for visitors to navigate. A responsive design ensures your content fits well on all screen sizes.
Tools to Test Mobile Friendliness
To make sure your website is mobile-friendly, there are some great tools that can help you test it and find any issues.
- Google Mobile-Friendly Test: This tool shows you how well your site works on mobile devices and gives you tips on how to improve it.
- Google Search Console: This tool provides a mobile usability report, letting you know if there are any issues with how your site displays on mobile.

Advanced Technical SEO Tactics
To improve your website’s performance and visibility, you need to use advanced SEO strategies. Here are some important techniques that can help.
Using hreflang for Multilingual Sites
If your website is available in different languages or for different regions, using hreflang tags is important. These tags let search engines know which version of your site should be shown to users based on their language or country.
This prevents issues like duplicate content and ensures people see the correct version of your site. For example, if you have English and Spanish versions of your site, hreflang tags help Google show the right one to users depending on their language.
JavaScript SEO: Best Practices
JavaScript adds life to your website by making it more interactive, but if not handled properly, it can create challenges for search engines trying to read your content. To ensure that search engines can read and index JavaScript content properly, follow these best practices:
- Make sure content loads properly: Search engines need to be able to read and understand your JavaScript content. Use tools like Google Search Console to check how Google views your site’s JavaScript content.
- Don’t block JavaScript files: Make sure your important JavaScript files aren’t blocked in your robots.txt file, or search engines might not be able to see your site properly.
- Basic content first: Ensure that basic content loads on the page, even if JavaScript isn’t available, so users can still see the important information.
Content Delivery Networks (CDNs) and Technical SEO
A Content Delivery Network (CDN) is a system of servers that help deliver your website’s content faster to users around the world.
CDNs store copies of your site on different servers, so users can access your content from the server closest to them. This reduces loading times, improves the user experience, and boosts your SEO rankings, as search engines like Google prefer faster websites.
Server-Side vs Client-Side Rendering
Your website’s content can be shown using either server-side rendering, where the server loads the content first, or client-side rendering, where the visitor’s browser puts it together.
- Server-side rendering (SSR): This means the server creates the content before sending it to the browser. It’s great for SEO because search engines can access the full content immediately.
- Client-side rendering (CSR): In this method, the browser creates the content after the page loads. While it can improve user experience, search engines might have trouble reading the content unless the JavaScript is properly handled.
Each method has its own pros and cons, so it’s best to choose the one that works well with your website’s goals and setup.

Typical Technical SEO Issues and How to Fix Them
Technical SEO problems can harm your website’s performance. Here are some common issues and simple fixes to improve your site.
Duplicate Content
Duplicate content happens when the same content appears on more than one page, which can confuse search engines.
To fix this, use canonical tags to indicate the original page, or set up redirects to combine similar pages. Use tools like Google Search Console or Screaming Frog to find and fix duplicate content on your site.
Thin Content
Thin content refers to pages that have little or no useful information.
To fix this, add more valuable content to these pages, such as text, images, or videos that answer questions or solve problems. Aim to provide complete, informative content that adds value for your users.
Slow Site Speed
Slow websites affect both user experience and search rankings. To speed up your site, optimize images, reduce the size of files, and use a Content Delivery Network (CDN).
Tools like Google PageSpeed Insights can show what’s slowing your site down and give you tips to fix it.
Mixed Content Warnings
Mixed content occurs when secure HTTPS pages load non-secure HTTP elements like images or scripts. This can trigger warnings and hurt your site’s trustworthiness. To fix it, update all your resources to HTTPS, so everything on your site is secure.
Incorrect Canonical Tags
If your canonical tags are wrong or missing, search engines might not know which page to index, leading to duplicate content issues.
Check and make sure each page has the correct canonical tag pointing to the main version. This helps search engines rank the right page.
Orphan Pages and Poor Internal Linking
Orphan pages don’t have links pointing to them from other pages on your site, making them harder for search engines to find. To fix this, add internal links to these pages from other related content. A good internal linking structure helps search engines crawl your site better and improves SEO.
How frequently Should You Perform a Technical SEO Audit?
A technical SEO audit helps keep your website in top shape. Knowing how often to do an audit is key to ensuring everything runs smoothly.
Monthly vs Quarterly Audits
Performing a monthly audit is great for websites that get frequent updates or have a lot of content added. This helps catch any issues early. On the other hand, quarterly audits are often enough for websites that don’t change much or have stable content. It’s important to balance the frequency with how fast your website evolves.
Signs Your Website Needs an Audit Now
Sometimes your website might show signs that it needs an audit before the usual schedule. If you notice a drop in traffic, pages not ranking as well, or if Google Search Console reports errors, it’s time for an audit. Also, after big updates or redesigns, running a quick audit can help you catch any new issues that might affect your SEO.
Checklist for Ongoing Monitoring
- Monitor Site Speed: Check your page load times regularly.
- Track Crawl Errors: Monitor google search console regularly to spot and resolve any crawl errors that might affect your site’s visibility.
- Check for Broken Links: Make sure no pages or links are missing.
- Review Mobile Usability: Ensure your site is still mobile-friendly.
- Update Sitemap and Robots.txt: Ensure both are current and error-free.
