What is Technical SEO? Best Practices and a Checklist

Last updated on July 15, 2024 by RGB Web Tech

Technical SEO refers to the process of optimizing your website for the crawling and indexing phase. With technical SEO, you can help search engines access, crawl, interpret and index your website without any problems.

It is called “technical” because it has nothing to do with the actual content of the website or with website promotion. The main goal of technical SEO is to optimize the infrastructure of a website.

If you want your site to rank on Google and increase your brand's organic traffic, you’ll need to look at On Page SEO, Off Page SEO and Local SEO also.

But before you starting SEO also learn techniques of SEO ( White Hat SEO, Black Hat SEO, Gray Hat SEO and Negative SEO )

To understand what is the true meaning of technical SEO, let’s start with some basic terminology.

Technical SEO

1. Doctype

The HTML document type declaration, also known as DOCTYPE, is the first line of code required in every HTML or XHTML document. The DOCTYPE declaration is an instruction to the web browser about what version of HTML the page is written in. This ensures that the web page is parsed the same way by different web browsers.

In HTML 4.01, the DOCTYPE declaration refers to a document type definition (DTD). A DTD defines the structure and the legal elements of an XML document. Because HTML 4.01 was based on the Standard Generalized Markup Language (SGML), referring to a DTD in the DOCTYPE declaration was necessary.

Additionally, doctypes for HTML 4.01 required the declaration of either strict, transitional, or frameset DTD, each with a different use case as outlined below.

Strict DTD: Used for web pages that exclude attributes and elements that W3C expects to phase out as CSS support grows

Transitional DTD: Used for web pages that include attributes and elements that W3C expects to phase out as CSS support grows

Frameset DTD: Used for web pages with frames

In contrast, the declaration of HTML5 DOCTYPE is much simpler: it no longer requires a reference to DTDs as it is no longer based on SGML. See the examples below for a comparison between HTML 4.01 and HTML5 DOCTYPEs.


Doctype syntax for HTML5:

<!DOCTYPE html>

Doctype syntax for strict HTML 4.01:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">

Doctype syntax for transitional HTML 4.01:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

Doctype syntax for frameset HTML 4.01:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Frameset//EN" "http://www.w3.org/TR/html4/frameset.dtd">

2. Canonicalization

A canonical tag is a way of telling search engines that a specific URL represents the master copy of a page. Using the canonical tag prevents problems caused by identical or "duplicate" content appearing on multiple URLs. Practically speaking, the canonical tag tells search engines which version of a URL you want to appear in search results.

Canonicalization Examples

<link rel="canonical" href="https://www.rgbwebtech.com/" />
  • Versions of URLs with and without "www"
  • URLs with and without "index.html" at the end
  • Variants of URLs with "HTTP" and "HTTPS" protocols
  • Uppercase and lowercase letters in URLs

3. Robots.txt

Robots.txt is a text file webmasters create to instruct web robots (typically search engine robots) how to crawl pages on their website. The robots.txt file is part of the the robots exclusion protocol (REP), a group of web standards that regulate how robots crawl the web, access and index content, and serve that content up to users. The REP also includes directives like meta robots, as well as page-, subdirectory-, or site-wide instructions for how search engines should treat links (such as “follow” or “nofollow”).

In practice, robots.txt files indicate whether certain user agents (web-crawling software) can or cannot crawl parts of a website. These crawl instructions are specified by “disallowing” or “allowing” the behavior of certain (or all) user agents.

Basic format:

User-agent: Googlebot Disallow: /nogooglebot/ User-agent: * Allow: / Sitemap: http://www.example.com/sitemap.xml

4. Schema Markup

Schema markup is code that helps search engines to understand your content and better represent it in the search results.

Schema markup powers rich snippets, which often have higher clickthrough rates than ‘regular’ search results. That means more traffic to your site.

However, the primary function of the markup is to help search engines better understand your content.

It’s no coincidence that schema.org, the community behind the markup, was created a year before Google’s Knowledge Graph—a knowledge base of entities and the relationships between them—came to life.

And you guessed it, one of the primary sources for this data is the schema markup.

What are the types of Schema Markups?

There are hundreds of different markup types because there are so many different questions people turn to search engines to answer. But here are the 10 most common schema markups that are used.

  • Organization Schema Markup
  • Person Market Schema Markup
  • Local Business Schema Markup
  • Product & Offer Schema Markup
  • Breadcrumbs Markup
  • Article Schema Markup
  • Video Schema Markup
  • Event Schema Markup
  • Recipe Schema Markup
  • Rating/Review Schema Markup

5. Sitemaps Updates (XML, Text, HTML)

A sitemap helps search engines discover URLs on your site, but it doesn't guarantee that all the items in your sitemap will be crawled and indexed. However, in most cases, your site will benefit from having a sitemap.

It is also essential to know there are two different types of sitemaps.

  • XML sitemaps
  • HTML sitemaps

You can Generator Sitemaps for your website here

  • XML-Sitemaps - https://www.xml-sitemaps.com
  • Small SEO Tools - https://smallseotools.com/xml-sitemap-generator/

6. HTTP Status Codes

The Status-Code element in a server response, is a 3-digit integer where the first digit of the Status-Code defines the class of response and the last two digits do not have any categorization role. There are 5 values for the first digit:

  • 1xx: Informational : It means the request has been received and the process is continuing.
  • 2xx: Success : It means the action was successfully received, understood, and accepted.
  • 3xx: Redirection : It means further action must be taken in order to complete the request.
  • 4xx: Client Error : It means the request contains incorrect syntax or cannot be fulfilled.
  • 5xx: Server Error : It means the server failed to fulfill an apparently valid request.

7. Website Speed Optimization

The term page speed essentially refers to the length of time at which web pages or media content is downloaded from website hosting servers and displayed onto the requesting web browser. Page load time is the duration between clicking the link and displaying the entire content from the web page on the requesting browser.

You can test your website here

  • PageSpeed Insights - https://pagespeed.web.dev
  • GTmetrix - https://gtmetrix.com

Once you have tested the speed of your website, you can start optimizing it. There are a lot of different ways to make your website work faster and we created the list of the most effective ones.

  • Use a Content Delivery Network (CDN)
  • Move your website to a better host
  • Optimize the size of images on your website
  • Reduce the number of plugins
  • Minimize the number of JavaScript and CSS files
  • Use website caching
  • Implement Gzip Compression
  • Database optimization in CMS
  • Reduce the use of web fonts
  • Detect 404 errors
  • Reduce redirects
  • Use prefetching techniques

8. Web Hosting

Web hosting is an online service that allows you to publish your website files onto the internet. So, anyone who has access to the internet has access to your website. In practice, it usually refers to the service you get from a web hosting provider like Bluehost.com

9. Optimized Domain

An SEO-optimized domain name is a domain name that introduces your website and tells search engines and users what your website is about, or about the type of products and services it offers, etc. Such domains are more likely to stand out in the search result listings and to get clicked. So, a right domain name helps you target your audience and improve your search engine rankings. You can choose a branding domain or a keyword domain.

10. Redirects

Every page on the web has an address, a URL, which stands for ‘Uniform Resource Locator’. Sometimes, content moves from one URL to another URL. That’s when you need a redirect. A redirect automatically makes a browser go from one URL to another URL.

Types of redirects

  • Serverside redirects
  • Client-Side redirects

11. Core Web Vitals

Core Web Vitals are the subset of Web Vitals that apply to all web pages, should be measured by all site owners, and will be surfaced across all Google tools. Each of the Core Web Vitals represents a distinct facet of the user experience, is measurable in the field, and reflects the real-world experience of a critical user-centric outcome.

The metrics that make up Core Web Vitals will evolve over time. The current set for 2020 focuses on three aspects of the user experience—loading, interactivity, and visual stability—and includes the following metrics (and their respective thresholds):

  • Largest Contentful Paint (LCP): measures loading performance. To provide a good user experience, LCP should occur within 2.5 seconds of when the page first starts loading.
  • First Input Delay (FID): measures interactivity. To provide a good user experience, pages should have a FID of 100 milliseconds or less.
  • Cumulative Layout Shift (CLS): measures visual stability. To provide a good user experience, pages should maintain a CLS of 0.1. or less.

12. W3C Validation

W3C validation is the process of checking a website's code to determine if it follows the formatting standards. If you fail to validate your website's pages based on W3C standards, your website will most likely suffer from errors or poor traffic owing to poor formatting and readability.

Why Validate a Site on W3C?

  • Help Improve Rankings in Search Engines
  • Validation Helps Teach Best Practices
  • Improved Website User Experience
  • Make Website Browsers Friendly
  • Multiple Device Accessibility
  • Validation Help for Easy Coding and Maintenance
  • Validation as a Debugging Tool

How Do You Validate Your Code?

  • CSS Validator - https://jigsaw.w3.org/css-validator/

13. Google Search Console

Search Console is a tool from Google that can help anyone with a website to understand how they are performing on Google Search, and what they can do to improve their appearance on search to bring more relevant traffic to their websites.

Search Console provides information on how Google crawls, indexes, and serves websites. This can help website owners to monitor and optimize Search performance.

There is no need to log in to the tool every day. If new issues are found by Google on your site, you'll receive an email from Search Console alerting you.
