What does Technical SEO entail?

Technical SEO involves optimizing the technical aspects of a website to make it easier for search engines to crawl, understand, index and rank its web pages.

While content SEO addresses primarily keywords and valuable information, technical SEO concentrates on the behind-the-scenes functioning of your site. That involves the speed of the website, mobile friendliness, site structure, crawling and indexing, redirects, urls, structured data, HTTPS, XML sitemap and others.

Even the best content on a website may be difficult to rank in search results if search engines stick to crawling the pages and can't make sense of their content.

That's why technical SEO is vital to full SEO method.

Why is technical SEO important?

This means search engines must be able to find the pages of your site, crawl them, determine what's on them, and decide if they should be added to their search index.

Any of these steps could be interrupted by technical difficulties.

A site for example can have:

Broken internal links
Slow-loading pages
Incorrect redirects
Duplicate URLs
Missing canonical tags
Poor mobile usability
Incorrect robots.txt rules
XML sitemaps that are incomplete or contain the wrong properties
Security issues or HTTPS
When you can find a page that returns a 404 error!
The existence of JavaScript that stops important content from being found

Solving these issues can help search engines reach and comprehend your website more easily.

Technical seo also enhances the visitors experience. From this aspect, a well organized website, which is faster and mobile friendly is easier for the people to navigate.

What is Technical SEO, and How Does it Work?

There are basically three main areas of technical SEO that are important:

1. Crawling

To find and get pages on the internet, search engines offer services with automated programs (crawlers or bots).

Technical SEO can ensure that essential pages can be crawled efficiently.

For instance, internal links will enable bots to find connected pages, and a well-designed robots.txt document will include instructions on which sections of the website bots shouldn't index.

2. Indexing

Once a search engine has crawled a page, it then decides whether the page should be part of its index or not.

A page exists but can't find it in the search results because there are indexing issues.

Technical SEO can be useful for finding issues like accidental noindex directives, incorrect canonical URLs, duplicate pages, and inaccessible content.

3. Understanding

If you want search engines to comprehend what each page is about.

Search engines may find it easier to interpret a website if it has clear page structures, descriptive URLs, appropriate headings, internal links, structured data and useful content.

An important aspect of technical SEO includes the following factors:

Technical SEO consists of lots of elements. Here are a few of the most critical areas to look out for.

Website Crawlability

Crawlability is the ability of search engine crawlers to read the pages of your website.

A highly complex site, outdated or broken links, blocked resources or faulty robots.txt settings can cause crawling issues.

Extra care needs to be taken to ensure that content that is important is reachable, and your site provides a logical structure.

Website Indexability

A page might be crawled but it may not get indexed.

Indexability is about ensuring that pages you want to show up in search results aren't accidentally disallowed by search engines for some reason.

Check for:

Noindex tags
Incorrect canonical tags
Robots.txt restrictions
Redirect chains
Server errors
Duplicate pages
Soft 404 pages

Search Console can come in handy on deciding indexing problems with your site.

XML Sitemap

XML sitemap supplies a search engine with details of relevant URLs within your website.

Not all URLs on a sitemap will be indexed, but it can assist search engines find important pages.

Some of the URLs in a typical sitemap may look like:

Homepage
Blog posts
Category pages
Important service pages
Tool pages
Any of the other canonical urls you want to be discovered by search engines:

Do keep the “sitemap” clean and not have any URLs that result in an error message or redirect to another location or should not be indexed.

Robots.txt

Robots.txt is a file that contains the instructions for search engine bots.

Can be used to prevent some parts of the website from being crawled.

But, the robot.txt should be carefully configured. When important pages or resources are accidentally blocked, SEO issues will arise.

Suppose you block an entire directory filled with critical content on your site; search engines won't be able to access that content.

Website Speed

The speed of your pages plays a role in the overall performance of your website and user experience.

A longer loading time will not help the visitors to enjoy a website, particularly on mobile devices.

Some of the most effective methods of boosting a website's performance include:

Compressing images
Modern image formats instead of old codecs for still images.
Reducing unnecessary JavaScript
Removing unused CSS
Enabling browser caching
Server Response Time optimisation
Restricting the number of options users have in selecting their websites instead of allowing unlimited selection when a CDN is suitable to use.
Less unnecessary third party scripts

Through Website structure testing tools, you can determine certain execution enhancement openings.

Core Web Vitals

Core Web Vitals refers to a combination of metrics that assess key factors of web page experience.

They concentrate on things like:

Loading performance
Interactivity
Visual stability

To enhance these metrics can help provide a better user experience.

Technical SEO shouldn't be limited to squeezing perfect scores within a single testing tool, though. There are a number of things that affect search visibility, like content that's appropriate and of good quality, links and the usability of the website.

Mobile-Friendly SEO

Mobile Usability is critical to most websites because the majority of their visitors may be coming from mobile devices.

Your website should:

Properly work on smaller screens
Use readable text
Provide buttons that are easy to tap
Don't have to scroll horizontally
Quite compatible with mobile networks
Show significant information properly

By using a responsive design, you can help deliver a consistent experience, both on mobile, tablet, and desktop.

HTTPS and Website Security

If someone is connected to a website via HTTPS, it means that communications between the website and the user are encrypted.

Having a correctly set up SSL/TLS certificate helps ensure that information that is sent between users and the website is protected.

Ensure the website is always accessed via HTTPS and that any instances of the website accessed via http are redirected to https.

In addition, one should try to prevent mixed content issues: making critical resource requests over insecure connections from within secure pages.

URL Structure

Cleanes URL allows people and search engines to navigate the site.

For example:

example.com/technical-seo/

Comprehends relatively easily when compared to:

example.com/page.php?id=4728

Use descriptive URLs wherever possible indicating what the page is about.

Steer away from any unnecessary URL parameters, too many levels of folders and a changing URL.

Canonical Tags

Canonical tags are one way to provide a hint about which version to use when a site has more than one URL that offers similar or duplicate content.

Sometimes for example a product or article can be available with more than one URL.

Canonical tag can be used to tell which URL is the primary version.

Canonical tags need to be used in a uniform way with valid, preferred URLs.

Internal Linking

Linkages that are built in the same site are called internal links.

Solid internal linking can aid:

When visitors discover related content, it is easier for them to stay engaged with you:
Pages are found by search engines

Delegate within the website
Make connections between ideas
Improve website navigation

For instance, an article on key word research might link to key word density, SEO tools and on page SEO articles.

Have descriptive anchor text that provides information about the target page being linked.

Fixing Broken Links

Dead links can ruin the image of your website and may make site navigation more challenging.

Some of the typical examples of such links are:

Deleted pages
Changed URLs
Incorrect addresses
Missing files
Old website locations

Checking your website for broken internal links on a regular basis will help ensure that your website is healthy.

Redirects

Redirects indicate that a web address has been relocated.

The common use case for a 301 redirect is a page's permanent relocation.

For example:

example.com/old-page/

can redirect to:

example.com/new-page/

Do not perform 'unnecessary' redirect chains (A redirect from one URL to the other, to the other and back to the other).

Ideally, redirects should point directly to the final destination.

Duplicate Content

When duplicate or very similar pages exist, it may be difficult for search engines to decide which page they should consider the preferred page.

Duplicate URLs can be as a result of:

URL parameters
portable domain name servers (ports 80 and 443)
WWW and Non-WWW version(s)
Trailing slash variations
Printer-friendly pages
Duplicate product pages
Website filtering systems

Controlling duplicate URL variations through proper canonicalisation, redirects and inbound and outbound internal links.

Structured Data

It's a structured data that's a standardized method for giving supplementary details about the substance of a page.

Can be used to assist search engine understanding of entities and page types like:

Articles
Products
Organizations
Events
Breadcrumbs
Local businesses
FAQs, where eligible

There should be consistency between the structured data and what is being shown on the page. Structured data is structured information added to a webpage, which can be problematic if it is added that is not necessary or misleading.

Website Architecture

The structure of a website forms a logic of structure which is the global organization of its content.

For example:

Homepage >> Category >> Subcategory >> Individual page.

Visitors can more easily navigate your site and important content may make navigability easier for search engines.

Avoid building important pages that are several levels deep in the site with no helpful contextually relevant links to get there.

Server Errors

Search engines and visitors may not be able to find pages if there is a problem with the server.

One frequent case in point is the common 500 Internal Server Error.”

The other status codes of the HTTP include:

200 – Successful request
301 – Permanent redirect
302 – Temporary redirect
404 – Page not found
410 – Content permanently gone
500 – Internal server error
503 – Service unavailable

Checking the important URLs periodically can help identify any unforeseen server issues.

Technical SEO vs On-Page SEO

Although Technical SEO and on-page SEO go hand in hand, they do have different fields of work.

Technical SEO	On-Page SEO
Website speed	Content quality
Crawlability	Keyword targeting
Indexing	Title tags
XML sitemap	Meta descriptions
Robots.txt	Headings
Authoritative URLs	Content structure
HTTPS	Internal links
Mobile Mobile usability	Image optimization
Structured data	search intent

Technical SEO helps search engines find and understand a site, while on page SEO is more related to individual pages and their content.

Technical SEO is different from off-page SEO.Technical SEO and Off-Page SEO are not the same.

Off page SEO deals with signals and activities that are not present on your website.

Examples include:

Backlinks
Digital PR
Brand mentions
Online reputation
Outreach

Technical SEO is all about the website.

SEO typically is a mix of technical SEO, on page SEO, high-quality content, and or off-page activities.

How to Perform a Technical SEO Audit

First, crawl the website.To start with, crawl the website.

Crawl through a SEO Software Tool to identify URLs and technical issues.

Look for:

Broken links
Redirects
Missing titles
Duplicate pages
Status code errors
Canonical problems

Step 2: Check Indexing

Examine your search engine indexing reports and see which pages are:

Indexed
Not indexed
Crawled but not indexed
Redirected
Blocked
Returning errors

Step 3: Review Robots.txt

Ensuring key pages and resources don't get inadvertently blocked.

You shouldn't stop here, however.But this isn't the end of it!

Step 5: Test Website Speed

Analyse your key pages mobile and desktop.

On-site search for large pictures, unneeded scripts, slow servers, and other performance issues.

Now go to step 6 - Check Mobile Usability.Next, go to step 6 - Check Mobile Usability.

Ensure optimal functionality across all screen sizes.

The seventh step is to check internal links.Step 7 is to look at internal links.

Ensure valuable pages have relevant inbound or outbound links.

Step 8: Check HTTPS

Check that everything on your website is secured by SSL /HTTPS and if any of your pages are still hosting an “http” URL, confirm they are redirecting correctly.

Next, check the Canonical Tags.Then, check Canonical Tags.

Make sure the canonical is setting the right preferred URL's.

Identify and resolve "High Priority" problems.

Avoid attempting to correct all of the above at once.

Begin with those that are blocking search engines or users from reaching specific pages like server error, accidental no indexing, broken redirect, or blocked content.

Blocking Important Pages

A robots.txt rule might block crawlers from seeing pages that they should find.

Accidentally Using Noindex

A noindex directive may be able to help keep a page out of search results.

Creating Redirect Chains

There may be multiple redirections between the original URL and final URL which can create unnecessary requests.

Ignoring Mobile Performance

A site that effectively performs on a desktop but has a poor performance on a mobile can offer a bad user experience.

Using Duplicate URLs

Different versions of the same page can lead to multiple versions of a page.

Ignoring 404 Errors

Many broken internal links can result in a less effective website navigation.

Over-Optimizing Technical SEO

Technical SEO must develop a website that is useful to users, rather than a pursuit of optimal scores.

Use search and search engine improvement tips to address meaningful problems first and make improvements to help users and search engines.

Technical SEO may appear to be of little significance for smaller websites.

It might seem like Technical SEO doesn't count for smaller websites.

Yes.

Large sites aren't the only ones that can benefit from technical SEO.

Having a technically healthy website can also help a small blog, local business website, portfolio, SaaS website, or SEO tools website.

Smaller sites may have the edge, they can see what is good and what is not, and make changes to their structure more easily.

Crawlability, Indexability, Page Speed, Mobile Usability, Internal Linking, HTTPS, Redirects, and Sitemap configuration are the most critical aspects to get right.

The frequency of technical SEO audits can depend on the size of your website.

The frequency of technical SEO audits may vary depending on the size of your site.

Technical SEO review should be taken into account if:

Starting up a new website
Redesigning a website
Making any changes to the URL structure
Changing your account to “Keyword Redirection” mode in Ezoic.com
Changing from http to https.
CMS Technology and/or website changes
Putting a lot of new pages in
On a sudden drop in organic traffic

Continual monitoring can help to find potential issues before they snowball.

Technical SEO Checklist

Final Thoughts

Technical SEO provides the base for search engines to access, crawl, comprehend and process your site.

It's not a substitute for well-made content and quality SEO. Rather, it helps you to ensure that your valuable content has been adequately discovered and assessed.

Let's begin with the basics: crawlability, indexability, site structure, mobile usability, performance, HTTPS, internal links, redirects, canonical urls and XML sitemaps.

Don't all of a sudden solve every technical problem. First of all you should look at the issues that impact pages that matter and block users and search engines in an effective way.

A technically healthy site on its own, plus useful content and overall supply of SEO, offers a significantly improved platform for assuring ongoing growth through organic search.
