What is Technical SEO? Best Practices and a Checklist

What is Technical SEO?

Technical SEO refers to the process of optimizing your website’s technical aspects to improve its visibility in search engine results. It involves making your site faster, easier to crawl, and understandable for search engines. Unlike on-page SEO, which focuses on content, and off-page SEO, which involves link building, technical SEO deals with the infrastructure of your website.

Best Practices for Technical SEO

1. Website Speed Optimization

Why It Matters:

Fast-loading websites provide a better user experience and are favored by search engines.

Best Practices:

• Optimize images by compressing them without losing quality.

• Minimize the use of heavy scripts and plugins.

• Use browser caching and a Content Delivery Network (CDN) to reduce load times.

2. Mobile-Friendliness

Why It Matters:

With the majority of searches happening on mobile devices, Google prioritizes mobile-friendly websites.

Best Practices:

• Implement a responsive design that adjusts to different screen sizes.

• Ensure all elements, including buttons and text, are easily accessible on mobile devices.

• Use Google’s Mobile-Friendly Test tool to check your site’s mobile compatibility.

3. Secure Website (HTTPS)

Why It Matters:

Google uses HTTPS as a ranking signal. Secure websites are trusted more by users and search engines.

Best Practices:

• Obtain an SSL certificate and install it on your website.

• Ensure all pages on your site are served over HTTPS.

• Update internal links to use HTTPS.

4. XML Sitemap

Why It Matters:

An XML sitemap helps search engines understand your website’s structure and find all your pages.

Best Practices:

• Create an XML sitemap using tools like Yoast SEO or Google XML Sitemaps.

• Submit your sitemap to Google Search Console and Bing Webmaster Tools.

• Regularly update your sitemap as you add new content.

5. Robots.txt File

Why It Matters:

The robots.txt file tells search engines which pages to crawl and which to avoid.

Best Practices:

• Create a robots.txt file and place it in your site’s root directory.

• Specify disallow rules for pages you don’t want indexed, like admin pages or duplicate content.

• Test your robots.txt file using Google’s Robots Testing Tool.

6. Structured Data Markup

Why It Matters:

Structured data helps search engines understand the content of your pages better, which can enhance search results with rich snippets.

Best Practices:

• Use Schema.org markup to add structured data to your pages.

• Implement structured data for critical information like products, reviews, and events.

• Validate your structured data with Google’s Structured Data Testing Tool.

7. Canonicalization

Why It Matters:

Canonicalization prevents duplicate content issues by indicating the preferred version of a page.

Best Practices:

• Use the rel=“canonical” tag to specify the canonical URL for each page.

• Ensure that only one version of a page (either www or non-www, HTTP or HTTPS) is accessible.

• Check for and resolve any duplicate content issues.

8. URL Structure

Why It Matters:

Clean, descriptive URLs are easier for search engines and users to understand.

Best Practices:

• Use short, descriptive URLs that include target keywords.

• Avoid using special characters, numbers, and unnecessary parameters in URLs.

• Implement a consistent URL structure across your site.
