Technical SEO Basics for Websites

Technical SEO is the process of improving the technical parts of a website so search engines can crawl, understand and index its content more effectively.

1. What Is Technical SEO?

Technical SEO focuses on the technical foundation of a website. It helps search engines access website pages and understand their structure.

For example, a website may contain useful articles, but if search engines cannot access or index those pages, the content may not appear in search results.

Technical SEO does not guarantee higher rankings. It helps remove technical problems that may prevent a website from being properly discovered and understood.

2. Website Crawling and Indexing

What is crawling?

Crawling is the process through which search engines discover website pages by following links and reading information available on the web.

What is indexing?

Indexing happens when a search engine processes a page and decides whether it should be stored in its search index. Indexed pages may become eligible to appear in search results.

3. Improve Website Loading Speed

Visitors expect websites to load quickly. Slow pages can create a frustrating experience, especially on mobile devices and slower internet connections.

Some ways to improve website performance include:

• Compress images before uploading them.
• Use modern image formats such as WebP.
• Remove unnecessary JavaScript and CSS.
• Avoid loading unnecessary third-party scripts.
• Use browser caching where appropriate.
• Choose reliable hosting.

4. Make Your Website Mobile-Friendly

Many people browse websites using smartphones. Your website should adapt to different screen sizes and remain easy to use.

Check these important elements:

• Text should be readable without zooming.
• Buttons should be easy to tap.
• Images should fit the screen.
• Navigation should work on mobile devices.
• Visitors should not need horizontal scrolling.

5. Use HTTPS for Website Security

HTTPS protects the connection between a visitor's browser and your website using encryption.

A website using HTTPS normally starts with https:// and displays a secure connection indicator in modern browsers.

Make sure your hosting provider has an active SSL certificate and that your website redirects HTTP traffic to HTTPS.

6. Create an XML Sitemap

An XML sitemap is a file that lists important URLs on your website. It helps search engines discover pages that you want them to consider for crawling.

For example, a sitemap for a blog may include the homepage, blog page, About page and published articles.

After creating your sitemap, submit it through Google Search Console.

7. Understand robots.txt

The robots.txt file gives instructions to search engine crawlers about which parts of a website they may access.

A simple example is:

User-agent: *
Allow: /

Sitemap: https://yourdomain.com/sitemap.xml

Replace the example domain with your actual website domain. Remember that robots.txt is not a security tool and does not guarantee that a URL will be removed from search results.

8. Fix Broken Links and Error Pages

A broken link sends visitors to a page that cannot be found. This often happens when a page is deleted, renamed or linked incorrectly.

To reduce broken links:

• Check internal links regularly.
• Correct spelling mistakes in file names.
• Update links when pages are renamed.
• Use relevant redirects when moving pages.
• Remove links to pages that no longer exist.

9. Use Google Search Console

Google Search Console is a free service that helps website owners understand how their websites perform in Google Search.

You can use it to:

• Inspect individual URLs.
• Submit XML sitemaps.
• Check indexing reports.
• Identify some website usability and technical issues.
• Understand search impressions and clicks.
