What is Technical SEO and why is it important?
Technical SEO refers to a set of actions taken to improve a website’s crawlability and indexability by search engines, especially Google.
In other words, Technical SEO ensures that Google bots can easily find, review, and ultimately index your website’s pages.
This is important because if Google cannot properly understand your content, you will not achieve a good ranking in search results.
Technical SEO focuses on the technical aspects of a website, dealing with #optimizing site structure, page load speed, mobile compatibility, and website security.
The importance of Technical SEO for overall #SEO success is very high.
Even if you produce very high-quality and engaging content, without proper Technical SEO, your site might not be visible in search results.
Generally, Technical SEO is considered a prerequisite for content SEO and Off-Page SEO.
In today’s competitive world, Technical SEO is no longer an advantage, but a necessity.
Websites that pay attention to Technical SEO principles have a greater chance of attracting organic traffic and increasing sales.

Several factors play a role in Technical SEO, but some are more important than others.
Here we highlight the most important of these factors in 2025:
- Page Speed Page load speed is one of Google’s most important ranking factors.

Improving URL Structure for Better SEO
Improving URL Structure for Better SEO
URL structure is another important factor in Technical SEO.
Clear, readable, and content-relevant URLs help search engines better understand page content.
Follow these tips to improve your URL structure:
- Use Keywords in URLs. The URL should contain keywords relevant to the page content.
- Keep URLs Short and Concise. Avoid using long and complex URLs.
- Use hyphens (-) instead of underscores (_). Google considers hyphens as word separators in URLs, but ignores underscores.
- Use lowercase letters. Using lowercase letters in URLs prevents potential issues.
- Avoid Duplicate URLs. Each page of your website should have a unique URL.
For example, instead of using an inappropriate URL like `www.example.com/page123`, use a more optimized URL like `www.example.com/seo-technical-guide`.
The Role of HTTPS in Website Security and SEO
The Role of HTTPS in Website Security and SEO
HTTPS is a secure protocol for transferring data between a website and users’ browsers.
Using HTTPS protects user information from hackers and shows Google that your website is secure.
Google has considered HTTPS as a ranking factor since 2014.
Websites that use HTTPS achieve a better ranking in search results.
To enable HTTPS, you need to obtain an SSL/TLS certificate and install it on your server.
SSL/TLS certificates are offered by various companies and have different prices.
In addition to improving SEO, using HTTPS has other benefits, including:
- Increased User Trust Users trust websites that use HTTPS more.
- Prevention of Man-in-the-Middle Attacks HTTPS protects user information from Man-in-the-Middle attacks.
- Improved Site Speed In some cases, using HTTPS can also improve site load speed.
If you are not yet using HTTPS, it is recommended to enable it as soon as possible.
Improving site security significantly helps SEO, and your site’s ranking in search results will improve.

Structured Data helps search engines better understand the content of your website pages.

- Publication Date
