Technical SEO: A Simple Guide to Better Website Performance

Creating useful content is an important part of SEO, but content alone is not enough. Your website also needs a strong technical foundation so that search engines can discover, crawl, and understand your pages.

This is where technical SEO comes in.

Technical SEO focuses on improving the technical aspects of a website that can affect crawling, indexing, performance, and user experience.

In this beginner-friendly guide, we'll explain technical SEO, why it matters, the most important technical SEO factors, and practical steps you can take to improve your website.

What Is Technical SEO?

Technical SEO is the process of improving the technical structure and performance of a website to help search engines access and understand its content.

Unlike on-page SEO, which focuses mainly on page content and elements such as titles and headings, technical SEO focuses more on the website's underlying structure and functionality.

Technical SEO can involve:

• Website crawling
• Indexing
• Site speed
• Mobile usability
• XML sitemaps
• Robots.txt
• HTTPS
• Canonical URLs
• Website architecture
• Structured data
• Core Web Vitals

The goal is to create a website that is technically accessible while also providing a good experience for visitors.

Why Is Technical SEO Important?

Imagine you have written an excellent article, but search engines cannot properly access or index the page.

Your content may have difficulty appearing in search results.

A technically healthy website can make it easier for search engines to discover and understand important pages.

Technical SEO can help you:

Improve Crawling

Search engine crawlers need to access your website's pages. A clear website structure can make this process easier.

Support Indexing

Search engines need to understand which pages should potentially be included in their index.

Improve Website Performance

A faster and more responsive website can provide a better experience for visitors.

Improve Mobile Experience

Your website should work properly across smartphones, tablets, and desktop devices.

Create a Better Website Structure

A logical structure helps both visitors and search engines navigate your website.

How Do Search Engines Crawl Websites?

Search engines use automated programs, commonly called crawlers, to discover webpages.

A crawler may discover a page through:

• Internal links
• External links
• Sitemaps
• Previously known URLs

Once a page is discovered, the search engine can process and evaluate its content.

This is why your website should have a logical structure with useful internal links connecting related pages.

What Is Website Indexing?

Indexing is the process through which a search engine analyzes and stores information about webpages that it may use in search results.

Not every page discovered by a search engine will necessarily be indexed.

For important pages, make sure they are:

• Accessible to crawlers
• Not unintentionally blocked
• Properly linked internally
• Useful and unique
• Technically functional

1. Improve Website Speed

Website performance matters because slow pages can create a poor user experience.

Large images, unnecessary scripts, excessive plugins, and poorly optimized resources can contribute to slower loading.

Some ways to improve performance include:

• Compressing images
• Using appropriate image formats
• Reducing unnecessary scripts
• Keeping pages lightweight
• Using reliable hosting
• Checking performance regularly

Don't focus only on making a website load quickly in a perfect test environment. Consider the actual experience of your visitors as well.

2. Make Your Website Mobile-Friendly

Today, many users browse websites using smartphones.

Your website should therefore work properly on different screen sizes.

Check that:

• Text is readable
• Buttons are easy to tap
• Navigation works correctly
• Images fit the screen
• Content does not require horizontal scrolling

A responsive website provides a better experience for mobile visitors.

3. Use HTTPS

HTTPS helps protect information exchanged between a website and its visitors.

You can check whether your website uses HTTPS by looking at its address.

A secure website normally begins with:

https://

rather than:

http://

For a professional business website, HTTPS should be properly configured across the site.

4. Create an XML Sitemap

An XML sitemap provides search engines with information about important URLs on your website.

A sitemap can be particularly useful for larger websites or websites with complex structures.

For many website platforms, including Odoo, sitemap functionality may be generated automatically.

You should still check that your sitemap is accessible and contains the URLs you actually want search engines to discover.

5. Understand Robots.txt

A robots.txt file provides instructions to crawlers about which areas of a website they may or may not access.

It is important to remember that robots.txt is not a general security system.

Do not use it as a way to protect confidential information.

If you manage a website, review your robots.txt configuration to make sure important pages are not accidentally blocked.

6. Use Canonical URLs

Sometimes similar or duplicate versions of a page can be accessible through different URLs.

A canonical URL can help indicate which version should be treated as the preferred URL.

Canonicalization becomes especially useful when websites have:

• Similar pages
• URL parameters
• Duplicate versions
• Multiple URLs leading to similar content

Correct implementation can help search engines understand your preferred page.

7. Fix Broken Links

Broken links can create a frustrating experience for visitors.

For example, if a blog links to a page that no longer exists, visitors may encounter an error.

Regularly check your website for:

• Broken internal links
• Incorrect URLs
• Missing pages
• Redirect issues

If you remove or permanently move an important page, consider whether a relevant redirect is appropriate.

8. Create a Logical Website Structure

A good website structure helps visitors find information easily.

For a digital marketing website like TezRank, your structure might look like:

Homepage

→ SEO Services

→ Local SEO

→ Digital Marketing

→ Google Ads

→ Content Writing

→ Blog

Your blog can then contain related articles such as:

→ SEO Basics

→ On-Page SEO

→ Technical SEO

→ Local SEO

→ Keyword Research

This creates logical connections between related topics.

9. Use Internal Links

Internal linking is important for both navigation and website structure.

For example, this article about technical SEO can link to your On-Page SEO article when discussing the difference between on-page and technical optimization.

Similarly, your SEO beginner article can link to this technical SEO guide.

This helps visitors discover related information without having to search for it themselves.

10. Understand Core Web Vitals

Core Web Vitals are metrics designed to measure important aspects of user experience.

They focus on areas such as:

• Loading performance
• Responsiveness
• Visual stability

These metrics can help website owners identify performance problems that may affect visitors.

Rather than optimizing only for a score, focus on creating a website that feels fast, responsive, and stable for real users.

11. Use Structured Data Where Appropriate

Structured data is a standardized way of providing information about the content of a webpage to search engines.

Depending on the page, structured data can describe things such as:

• Articles
• Products
• Organizations
• Events
• Local businesses
• FAQs

Structured data should accurately represent the visible content on the page. It should not be used to provide misleading information.

12. Check Your Website for Duplicate Pages

Duplicate or substantially similar pages can make it harder to maintain a clear website structure.

Review your website regularly and ask:

• Do multiple URLs show essentially the same content?
• Are there unnecessary pages?
• Are old versions of pages still accessible?
• Are canonical URLs configured appropriately?

Keeping your website organized can make ongoing SEO management easier.

Common Technical SEO Mistakes

Blocking Important Pages

An incorrect robots.txt or other configuration can accidentally prevent crawlers from accessing important content.

Ignoring Mobile Users

A website that looks good on desktop but is difficult to use on mobile can create a poor experience.

Uploading Huge Images

Large image files can unnecessarily increase page loading time.

Creating a Complicated Website Structure

Visitors should not have to navigate through many unnecessary pages to find important information.

Forgetting Broken Links

Old or incorrect links should be identified and fixed where appropriate.

Focusing Only on SEO Tools

SEO tools are useful for identifying potential problems, but the ultimate goal should be a website that works well for real visitors.

Technical SEO vs On-Page SEO

These two areas are closely related but focus on different things.

On-page SEO focuses on elements such as:

• Content
• Titles
• Headings
• Keywords
• Images
• Internal links

Technical SEO focuses more on:

• Crawling
• Indexing
• Website architecture
• Performance
• Mobile usability
• Sitemaps
• Technical accessibility

A successful SEO strategy can involve both.

How to Start Technical SEO as a Beginner

You don't need to fix everything at once.

Start with these steps:

Step 1: Check Your Website

Review your important pages and make sure they work correctly.

Step 2: Check Mobile Experience

Open your website on a smartphone and test navigation, buttons, images, and text.

Step 3: Check Website Speed

Identify pages that may have performance problems.

Step 4: Review Indexing

Make sure important pages are available for search engines to discover and process.

Step 5: Check Internal Links

Connect relevant pages and articles together.

Step 6: Check Your Sitemap

Make sure your sitemap is accessible and contains appropriate URLs.

Step 7: Monitor Your Website

Technical SEO is not a one-time task. Continue checking your website as you add new pages and content.
