Technical SEO
Technical SEO is all about improving a website’s technical aspects to increase its pages’ ranking in the search engines. Making a website faster, easier to crawl, and more understandable for search engines are the pillars of technical optimization. Technical SEO is part of on-page SEO, which focuses on improving elements on your website to get higher rankings. It’s the opposite of off-page SEO, which is about generating exposure for a website through other channels.
Google and other search engines want to present their users with the best possible results for their queries. Therefore, Google’s robots crawl and evaluate web pages on many factors. Some factors are based on the user’s experience, like how fast a page loads. Other factors help search engine robots grasp what your pages are about. This is what, among others, structured data does. So, by improving technical aspects, you help search engines crawl and understand your site. If you do this well, you might be rewarded with higher rankings. Or even earn yourself some rich results!
It also works the other way around: if you make serious technical mistakes on your site, they can cost you. You wouldn’t be the first to block search engines entirely from crawling your site by accidentally adding a trailing slash in the wrong place in your robots.txt file.
But don’t think you should focus on the technical details of a website to please search engines. A website should work well – be fast, clear, and easy to use – for your users in the first place. Fortunately, creating a strong technical foundation often coincides with a better user and search engine experience.
Technical SEO refers to the process of optimizing a website's infrastructure and backend elements to improve its search engine visibility and performance. Unlike traditional SEO, which focuses on content and keywords, technical SEO deals with the technical aspects of a website that affect its crawlability, indexability, and overall user experience.

301 Redirect
301 is an HTTP status code sent by a web server to a browser. A 301 signals a permanent redirect from one URL to another, meaning all users that request an old URL will be automatically sent to a new URL. A 301 redirect passes all ranking power from the old URL to the new URL, and is most commonly used when a page has been permanently moved or removed from a website.
Page Speed
Page speed (also called “load speed”) measures how fast the content of a page loads. From an SEO standpoint, having a fast page speed is essential. Many factors, such as your web hosting and your page size, affect page load speed. Page speed also differs on the desktop and mobile versions of a page.
