What Is Technical SEO? 7 Powerful Basics Every Beginner Should Know

If you want your website to perform well in search engines, creating useful content is not the only thing you need to consider. Search engines also need to be able to access, crawl, understand, and index your website properly.

This is where technical SEO becomes important. Technical SEO focuses on the technical aspects of a website that can affect how search engines discover and process its pages and how easily visitors can use the site.

In this beginner-friendly guide, we will explain what technical SEO is and cover 7 essential basics that every website owner should understand.

What Is Technical SEO?

Technical SEO refers to improving the technical structure and performance of a website so that search engines can efficiently crawl and index its content and users can access the website easily.

Technical SEO can involve areas such as crawling, indexing, website architecture, XML sitemaps, mobile usability, page performance, URLs, redirects, HTTPS, and other technical elements.

Unlike content-focused SEO, technical SEO is generally less about what you write and more about how your website is built, organized, and made accessible.

Technical SEO is one part of the broader SEO process. It works alongside content optimization, keyword research, internal linking, and other SEO activities.

Google provides official guidance about how search engines crawl, index, and serve webpages through Google Search Central.

Why Does Technical SEO Matter?

Imagine creating an excellent article but making it difficult for search engines to discover or access the page. The quality of the content alone cannot solve every technical problem.

A technically healthy website can make it easier for search engines to discover important pages and understand the structure of your site.

Technical SEO can also contribute to a better user experience by improving areas such as website accessibility, mobile usability, loading performance, and navigation.

Technical SEO also works closely with on-page SEO. While technical SEO focuses more on the technical foundation of a website, on-page SEO focuses on the content and page-level elements visitors interact with.

Let’s look at seven important technical SEO basics.

1. Make Your Website Crawlable

Search engines use automated systems to discover and crawl webpages. If important pages cannot be accessed by search engine crawlers, those pages may have difficulty appearing in search results.

Your website should have a logical structure that allows search engines and visitors to move between important pages.

Internal links are useful for this purpose. For example, your on-page SEO guide can link to related SEO resources, helping visitors discover more information.

You should also pay attention to technical issues that may unintentionally prevent crawling, such as incorrect robots.txt rules, broken links, or problematic redirects.

A well-planned digital marketing website should also make important pages easy for both users and search engines to discover.

2. Make Important Pages Indexable

Crawling and indexing are not exactly the same thing.

Crawling is the process of discovering and accessing a webpage, while indexing is the process of analyzing and storing information about a page so that it can potentially appear in search results.

Not every page on a website necessarily needs to be indexed. For example, some administrative or duplicate pages may not be useful in search results.

However, your important pages should not accidentally contain settings that prevent search engines from indexing them.

You can use Google Search Console to inspect individual URLs and identify certain indexing-related issues. Our Google Search Console guide explains the tool in more detail.

3. Create and Submit an XML Sitemap

An XML sitemap is a file that provides information about important URLs on your website.

A sitemap can help search engines discover pages, especially when a website has many URLs or a complex structure.

For many WordPress websites, SEO plugins can automatically generate an XML sitemap.

After creating a sitemap, you can submit it through Google Search Console.

For example, a typical WordPress sitemap may be available at an address similar to:

https://example.com/sitemap_index.xml

The exact sitemap URL depends on your website and the SEO tools you use.

If you want to understand more about monitoring your sitemap and indexing status, see our guide on Google Search Console.

4. Use a Mobile-Friendly Website

A large number of people access websites using smartphones and other mobile devices. Therefore, your website should work properly across different screen sizes.

A mobile-friendly website should have:

• Readable text
• Easy-to-use navigation
• Buttons and links that are easy to tap
• Responsive layouts
• Content that fits smaller screens
• Images that display properly on mobile devices

Before publishing a page, check how it looks on both desktop and mobile devices.

5. Improve Website Speed and Performance

Website performance can affect the experience visitors have when using your site. Slow pages can make it harder for users to access information quickly.

Some practical ways to improve performance include:

• Compressing large images
• Using appropriate image formats
• Reducing unnecessary plugins and scripts
• Using reliable web hosting
• Keeping WordPress and plugins updated
• Using caching where appropriate

Performance optimization should focus on real user experience rather than simply trying to achieve a perfect score in every testing tool.

Image optimization is also an important part of on-page SEO. Our guide on On-Page SEO covers practical ways to optimize page elements, including images and content.

6. Use Clean and Descriptive URLs

A clear URL structure makes it easier for users to understand what a page is about.

For example:

Good:
https://example.com/technical-seo/

Less descriptive:
https://example.com/page?id=2847

A good URL is generally short, descriptive, and related to the page topic.

Avoid changing URLs unnecessarily. If you need to change an existing URL, make sure the appropriate redirect is configured so visitors and search engines can reach the new location.

For e-commerce websites, clean URLs can also help organize product and category pages alongside other optimization practices such as product page optimization.

7. Use HTTPS and Maintain Website Security

HTTPS encrypts the connection between a visitor’s browser and your website. It is an important part of maintaining a secure website.

Make sure your website uses a valid SSL certificate and loads correctly through HTTPS.

You should also keep your website software, themes, plugins, and other components updated and use strong authentication practices.

Website security is not only a technical consideration. A compromised website can create serious problems for both visitors and the website owner.

Technical SEO vs. On-Page SEO

Technical SEO and on-page SEO are related, but they focus on different areas.

Technical SEO	On-Page SEO
Crawling and indexing	Content optimization
XML sitemaps	Headings
Website performance	Keywords
Mobile usability	Images and alt text
HTTPS and redirects	Internal linking and content structure

In simple terms, technical SEO helps make the website accessible and understandable from a technical perspective, while on-page SEO focuses more directly on the content and elements of individual pages.

Both areas can work together as part of a broader digital marketing strategy.

Common Technical SEO Mistakes

Beginners often overlook technical SEO because many technical issues are less visible than content problems.

Some common mistakes include:

• Accidentally blocking important pages from crawling
• Using incorrect noindex settings
• Ignoring broken links
• Having multiple unnecessary URL versions
• Forgetting to maintain an XML sitemap
• Using very large unoptimized images
• Ignoring mobile usability
• Allowing outdated plugins or software to remain active
• Changing URLs without proper redirects

You do not need to become a professional developer to understand the basics. Start with the most important technical elements and gradually learn more as your website grows.
