📖 Introduction
My dear friends, before reading anything, it’s important to think why we actually need Technical SEO. Let’s dive a little deeper to understand how the need for Technical SEO arose and why it is so important.
The need for Technical SEO grew because website owners were mainly focused on content and keywords, while ignoring technical aspects. The problem was that every website had different site structures, speed, security, and mobile-friendliness.
That’s why Google created a rule: only those websites would rank in the search engine that do not have keyword stuffing, duplicate content, or spammy links.
Google started rolling out one algorithm update after another, and updates like Panda, Penguin, and Hummingbird were introduced. After these, it became necessary to properly optimize websites; otherwise, they would struggle to rank.
In the 2020s, AI technologies like BERT and MUM began focusing on user intent and context, making natural keyword use, high-quality content, and good user experience the top priorities. Technical SEO saw increased use of AI and NLP.
In the past, websites could rank even without proper Technical SEO, but in today’s era of high competition, things have completely changed.
It means how technically fit your website is — whether your website speed is fast or not, whether it is mobile-friendly, and whether search engines can easily crawl and index it.
Google has set strict criteria, and if we don’t follow them, it becomes difficult to move ahead in the digital world. That’s why, if you want to improve your website’s ranking, you must first understand Technical SEO thoroughly and work on improving it.
⚙️ What is Technical SEO?
- Making the site structure SEO-friendly.
- Improving website speed and performance.

If a developer has created a website, but the URLs are not keyword-rich, the design is not mobile-friendly, then I am facing indexing problems – then all these are solved through technical SEO.
Technical SEO makes your site optimized for search engines and users.
Note- It makes sure that your website is easy for Google and other search engines to crawl, understand, and index.
Let us understand from basic to advanced, whether you are a student or a business or a YouTuber, I will explain it to you in simple language.
Website Speed: Important factors for user experience and SEO
Website speed is a crucial factor in today's digital age. If your website is slow, users won't wait and will simply move on to another website.

🤔 Why Technical SEO is Important
Technical SEO is important because Google uses it as the basis to rank your website. Google checks all the technical aspects of your site — like website speed, mobile-friendliness, proper content, and structure.
If Google cannot crawl or index your website properly, it won’t appear in rankings, and your online visibility will suffer. In today’s era of AI-based search and Core Web Vitals updates, ignoring Technical SEO can be a big disadvantage for your website.
