Technical SEO is a part of on page SEO, which focuses on improving elements on your website to get upper rankings, it is the opposite of off-page SEO (search engine optimization), which is about generating exposure for a website through other channels.

Why Is Technical SEO Important?

Technical SEO can greatly impact a website’s performance on Search Engine.

If pages on your site are not accessible to Google, they won’t appear or rank in search results no matter how valuable your content is.

This results in a loss of traffic to your site and potential revenue to your business.

Plus, the mobile-friendliness and page speed of a website are Google-confirmed ranking factors.

1. What is XML Sitemap?

An XML sitemap is a file that lists a website’s important pages, making sure Google can find them and crawl them all easily. It also helps to search engines understand your website structure. You want to crawl every essential pages of your website.

2. What Is an HTML Sitemap?

An HTML sitemap is a file that lists every essential page on your website. This is designed to make navigation easier for your users. You will normally find an HTML sitemap on a website footer, where everybody can access it:

Each item in the HTML sitemap links to the related page. Hence, if a user is looking for a particular page or category on your website, they can use the HTML sitemap to locate and access it quickly. This can help improve your User Experience and increase your engagement rate.

It’s worth noting that an HTML sitemap is diff. from an XML sitemap. The latter is less human-friendly, and designed to enable search engines like Google, Yahoo, and Bing to crawl and index your content.

Both HTML and XML sitemaps can be helpful for your website. The HTML sitemap serves as a directory for your users, enabling them to easily access every essential page on your website. This can be particularly handy if you have a large number of subpages. Meanwhile, the XML sitemap provides search engine bots with information about every essential URL on your website, and how all of those pages interconnect. This way, the bots immediately know what content is available, and index it faster. As such, an XML sitemap can be very beneficial if you have a complex site architecture.

3. What is robots.txt?

Robots.txt is a file that tells search engines crawlers not to crawl certain pages or section of a website.

A robots.txt file is a text file that webmasters create to instruct web robots (typically search engine crawlers) how to crawl and index pages on their website. The file is placed in the root directory of a website and contains directives that specify which areas of the site should not be crawled or indexed by search engines.

The main purposes of a robots.txt file are:

  1. Control Crawling: Webmasters use robots.txt to communicate with web crawlers and prevent them from accessing specific parts of their website. This is particularly useful for excluding content that is not meant to be publicly accessible or pages that may be duplicated in other parts of the site.
  2. Preserve Bandwidth: By preventing crawlers from accessing certain parts of the site, webmasters can conserve bandwidth and server resources. This is especially important for large websites with extensive content.
  3. Privacy Concerns: Some website owners use robots.txt to address privacy concerns by disallowing the indexing of certain pages that may contain sensitive information.
  4. Directives:
    • The main directives used in a robots.txt file are “User-agent” and “Disallow.”
      • “User-agent” specifies the web crawler or user agent to which the rule applies.
      • “Disallow” specifies the URLs or directories that should not be crawled.
  5. Wildcard Usage: Wildcards, such as “*” (asterisk), can be used to create broader rules. For example, “User-agent: *” applies the rule to all web crawlers.

4. Page Loading Time

Page load time is the average amount of time it takes for a page to show up on your desktop screen. It’s calculated from the beginning (when you click on a page link or type in a Web address) to the conclusion (when the page is fully loaded in the browser).

6. SSL Certificate

What is SSL Certificate?

SSL, often referred to as TLS, stands for a protocol designed to encrypt internet traffic and authenticate server identities. Websites employing an HTTPS web address leverage SSL/TLS for enhanced security. To delve deeper into SSL and TLS, refer to resources explaining What SSL is and What TLS entails.

How do SSL certificates work?

SSL certificates contain the following information in a single data file:

  • The specific domain for which the certificate was issued
  • Which person, organization, or device it was issued to
  • Which certificate authority issued it
  • Associated subdomains
  • Issue date of the certificate
  • The certificate authority’s digital signature
  • Expiration date of the certificate
  • The public key (the private key is kept secret)

Public and private keys used for the Secure Sockets Layer (SSL) are essentially long strings of characters used for encrypting and signing data. Data encrypted with the public key can only be decrypted with the private key.

The SSL certificate is hosted on a website’s origin server and is sent to any devices that request to load the website. Most browsers enable users to view the Secure Sockets Layer certificate: in Chrome, this can be done by clicking on the padlock icon on the left side of the URL bar.

7. Canonical Tag

The World Wide Web Consortium (W3C) provides a platform for internet users to examine HTML and XHTML documents, ensuring they adhere to well-structured markup standards. The validation of markup is a crucial process in upholding the technical quality of web pages.
