Parts Of Technical SEO: So You Know What You Need To Learn

Welcome to the ultimate guide on Technical SEO! Whether you’re a seasoned professional or just starting out, this guide will provide you with in-depth insights into the critical aspects of Technical SEO. Let’s dive in!

1. Duplicate Content: Understanding and Resolving It

What is Duplicate Content?

Duplicate content refers to blocks of text or entire pages that appear on multiple URLs, either within your website or across different sites. This can confuse search engines, leading to potential ranking issues.

Why Duplicate Content Matters

Search Engine Confusion: When search engines encounter identical content on multiple URLs, they struggle to determine which version to index and rank.
Diluted Link Equity: Backlinks pointing to different versions of the same content can dilute the overall link equity, affecting page authority.
Potential for Lower Rankings: Search engines may choose to display a less relevant version of your content or, in some cases, omit it from search results altogether.

Common Causes of Duplicate Content

URL Variations: Parameters used for tracking or sorting can create multiple URLs with the same content.
Printer-Friendly Versions: Separate URLs for printer-friendly pages can lead to duplication.
HTTP vs. HTTPS or www vs. non-www: Serving content on both secured and unsecured versions, or with and without “www,” can result in duplicates.

Strategies to Address Duplicate Content

Implement Canonical Tags
Use the <link rel=”canonical” href=”URL” /> tag to indicate the preferred version of a page. This helps consolidate ranking signals to the chosen URL.
Set Up 301 Redirects
Redirect duplicate URLs to the primary version to ensure both users and search engines access the correct page.
Consistent Internal Linking
Ensure internal links point to the preferred version of a page to avoid creating unnecessary duplicates.
Configure URL Parameters in Google Search Console
Inform Google about how to handle URL parameters to prevent them from being treated as separate pages.
Use Robots.txt to Block Duplicate Pages
Prevent search engines from crawling and indexing duplicate pages by disallowing them in your robots.txt file.

2. Page Speed: Enhancing User Experience and Rankings

Why Page Speed is Crucial

User Experience: Faster-loading pages lead to higher user satisfaction and lower bounce rates.
Search Engine Rankings: Google considers page speed as a ranking factor, especially with the introduction of Core Web Vitals.
Conversion Rates: Improved load times can lead to higher conversion rates, directly impacting revenue.

Factors Affecting Page Speed

Large Image Files: Uncompressed images can significantly slow down page load times.
Render-Blocking Resources: CSS and JavaScript files that prevent a page from loading quickly.
Server Response Time: Slow servers can delay the initial loading of a page.
Excessive HTTP Requests: Multiple requests for various resources can increase load times.

Strategies to Improve Page Speed

Optimize Images
Compress images using formats like WebP and ensure they are appropriately sized for their display dimensions.
Minify CSS, JavaScript, and HTML
Remove unnecessary characters and spaces to reduce file sizes without affecting functionality.
Leverage Browser Caching
Set up caching to store static resources on users’ devices, reducing load times for subsequent visits.
Use a Content Delivery Network (CDN)
Distribute your content across multiple servers worldwide to ensure faster delivery to users based on their geographic location.
Reduce HTTP Requests
Combine files where possible and eliminate unnecessary plugins or scripts to minimize the number of requests.
Implement Lazy Loading
Load images and videos only when they are about to enter the viewport, reducing initial load times.

3. Crawlability: Ensuring Search Engines Can Access Your Content

What is Crawlability?

Crawlability refers to a search engine’s ability to access and navigate your website’s content. If search engines can’t crawl your site effectively, your content won’t appear in search results.

Factors Impacting Crawlability

Internal Linking Structure: A well-organized structure helps search engines discover all your pages.
Robots.txt File: Incorrect configurations can block search engines from accessing important pages.
XML Sitemaps: A comprehensive sitemap guides search engines to your key content.
Broken Links: Dead links can hinder search engines from crawling your site efficiently.

Strategies to Improve Crawlability

Optimize Internal Linking
Ensure a logical structure where important pages are easily accessible within a few clicks.
Regularly Update Your XML Sitemap
Keep your sitemap current and submit it to search engines to guide them to your latest content.
Audit and Fix Broken Links
Use tools to identify and repair broken links that could impede crawling.
Review Robots.txt Settings
Ensure that your robots.txt file isn’t inadvertently blocking essential pages from being crawled.
Implement Breadcrumb Navigation
Breadcrumbs help both users and search engines understand the structure of your site, enhancing crawlability.

4. Robots.txt: Controlling Search Engine Access

What is Robots.txt?

The robots.txt file is a simple text file that tells search engine crawlers which parts of your site they can or cannot access. It is placed in the root directory of your website (https://example.com/robots.txt).

Why Robots.txt is Important

Prevents search engines from crawling irrelevant or sensitive pages (e.g., admin pages, login areas).
Helps optimize crawl budget by preventing search engines from wasting resources on unimportant pages.
Avoids duplicate content issues by blocking pages that shouldn’t be indexed.

How to Create a Robots.txt File

A basic robots.txt file looks like this:

User-agent: *  

Disallow: /admin/  

Allow: /public-content/

Sitemap: https://example.com/sitemap.xml

User-agent: * – Applies to all search engines.
Disallow: /admin/ – Blocks the /admin/ directory from being crawled.
Allow: /public-content/ – Allows crawling of /public-content/.
Sitemap: – Points search engines to the XML sitemap.

Be Careful! If misconfigured, a robots.txt file can accidentally block your entire website from Google. Always test your robots.txt file using Google Search Console’s Robots.txt Tester.

5. Structured Data: Enhancing Search Visibility

What is Structured Data?

Structured data is a special format (Schema Markup) that helps search engines better understand your content. It allows your site to qualify for rich results, such as review stars, recipe snippets, or FAQ sections.

Why It’s Important

Helps Google display rich snippets, improving CTR.
Helps search engines understand content context.
Increases visibility in voice search and Google Discover.

How to Implement Schema Markup

Example JSON-LD Schema for a Blog Post:

{

  "@context": "https://schema.org",
  "@type": "BlogPosting",
  "headline": "How to Improve Page Speed for SEO",
  "author": {
    "@type": "Person",
    "name": "John Doe"
  },

  "publisher": {
    "@type": "Organization",
    "name": "SEO Experts"
  },
  "datePublished": "2024-02-01"
}

Steps to Implement Schema Markup:

Use Google’s Structured Data Markup Helper to generate code.
Add the generated JSON-LD script inside the <head> section of your pages.
Test it using Google’s Rich Results Test.

6. Internal Linking: Strengthening SEO Through Smart Navigation

What is Internal Linking?

Internal linking refers to links that connect different pages within your website. These links help users navigate the site and assist search engines in understanding site structure and content relationships.

Why Internal Linking Matters

Distributes Link Equity: Passes ranking power to important pages.
Improves Crawlability: Ensures that all pages are easily found by search engines.
Enhances User Experience: Helps users find relevant content easily.

Best Practices for Internal Linking

Use descriptive anchor text (e.g., “Learn about technical SEO” instead of “Click here”).
Link to important pages from high-authority pages.
Ensure every page is accessible within 3 clicks from the homepage.
Fix broken or outdated internal links.

7. XML Sitemaps: Helping Google Find Your Content

What is an XML Sitemap?

An XML Sitemap is a structured file listing all the important pages on your site. It helps search engines discover, crawl, and index your pages efficiently.

How to Create an XML Sitemap

A simple XML sitemap looks like this:

<urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9">
  <url>
    <loc>https://example.com/page-1</loc>
    <lastmod>2024-02-01</lastmod>
    <priority>0.8</priority>
  </url>
</urlset>

Ways to Generate a Sitemap:
✅ Use an SEO plugin (Yoast SEO, Rank Math) for WordPress.
✅ Use an online tool like XML-Sitemaps.com.
✅ Manually create and upload it to your root directory.

How to Submit Your Sitemap to Google:

Log into Google Search Console.
Go to Sitemaps → Enter your sitemap URL.
Click Submit and monitor for any errors.

8. URL Structure: Keeping It Clean and SEO-Friendly

Best Practices for SEO-Friendly URLs

✅ Keep URLs short and descriptive (e.g., example.com/best-seo-tips).
✅ Use hyphens (-) instead of underscores (_) to separate words.
✅ Avoid using dynamic parameters (e.g., ?id=123).
✅ Make URLs readable for humans.

Example of a Good URL:
✅ https://example.com/seo-tips-for-beginners
Example of a Bad URL:
❌ https://example.com/index.php?page=seo-tips&id=12345

9. HTTPS Security: Why SSL is Essential

Why HTTPS Matters for SEO

Google prioritizes HTTPS websites in rankings.
Protects user data from hackers.
Boosts credibility and user trust.

How to Secure Your Site with HTTPS

✅ Purchase an SSL certificate from your hosting provider.
✅ Install the certificate and update all URLs to https://.
✅ Set up 301 redirects from HTTP to HTTPS.
✅ Update your Google Search Console profile to the HTTPS version.

10. Indexation: Ensuring Your Pages Appear in Google Search

What is Indexation?

Indexation refers to Google storing and listing your web pages in its search index. If a page is not indexed, it won’t appear in search results—no matter how great your content is.

How to Check if a Page is Indexed

✅ Google Search Console → Inspect URL tool
✅ Use the site: operator in Google:

site:example.com/page-you-want-to-check

If the page appears, it is indexed.

How to Fix Indexation Issues

1. Ensure Your Page is Not Blocked by robots.txt

Check your robots.txt file to ensure it’s not blocking important pages.

🚨 Wrong Robots.txt Blocking Indexation (DO NOT DO THIS)

User-agent: *

Disallow: /

This blocks everything from being indexed!

2. Use the Right Meta Tags

If your page has the noindex tag, Google will not index it.

<meta name="robots" content="noindex">

✅ To fix this, remove the noindex tag.

3. Submit the Page for Indexing in Google Search Console

Open Google Search Console.
Use the URL Inspection Tool.
Click “Request Indexing”.

4. Improve Content Quality

Ensure your page has original, high-quality content.
Avoid thin content (short, unhelpful pages).
Follow E-E-A-T principles (Experience, Expertise, Authoritativeness, and Trustworthiness).

11. Redirects: Managing URL Changes Without Losing SEO Value

What Are Redirects?

A redirect is a way to send users and search engines from one URL to another.

Types of Redirects

🔄 301 Redirect (Permanent) – Best for SEO, transfers link equity.
🔄 302 Redirect (Temporary) – Not recommended for SEO.
🔄 307 Redirect (Temporary) – Used for HTTP to HTTPS changes.
🔄 Meta Refresh Redirect – Avoid for SEO, slower than server-side redirects.

How to Implement a 301 Redirect (SEO-Friendly)

For Apache servers, add this to your .htaccess file:

Redirect 301 /old-page https://example.com/new-page

For Nginx, use this:

rewrite ^/old-page$ https://example.com/new-page permanent;

✅ Always use 301 redirects when moving content permanently to preserve rankings.

12. Canonical Tags: Avoiding Duplicate Content Issues

What is a Canonical Tag?

A canonical tag tells search engines which version of a page is the preferred one when duplicate content exists.

Why Canonical Tags Are Important

Prevents duplicate content penalties.
Consolidates link equity to the preferred URL.
Helps Google rank the right version of a page.

How to Implement a Canonical Tag

Place this in the <head> section of duplicate pages:

<link rel="canonical" href="https://example.com/preferred-page">

✅ Always self-canonicalize your pages to avoid accidental duplication.

13. Hreflang Tags: Optimizing for Multilingual SEO

What is Hreflang?

Hreflang tags tell Google which language version of a page to display based on a user’s location and language settings.

Why Hreflang Matters

Prevents duplicate content issues for multilingual sites.
Ensures the right audience sees the right content.
Helps rank localized versions of your pages.

How to Implement Hreflang Tags

Place this in the <head> of each localized page:

<link rel="alternate" hreflang="en" href="https://example.com/en/">

<link rel="alternate" hreflang="fr" href="https://example.com/fr/">

✅ Ensure each page links to every language version.

14. Mobile Friendliness: A Must for SEO Success

Why Mobile SEO Matters

Google uses mobile-first indexing (it ranks your site based on its mobile version).
Over 60% of searches happen on mobile.
Slow, unoptimized mobile sites lose visitors fast.

How to Make Your Site Mobile-Friendly

✅ Use a responsive design (adapts to all screen sizes).
✅ Optimize Core Web Vitals (Largest Contentful Paint, Cumulative Layout Shift).
✅ Use Google’s Mobile-Friendly Test to check your site’s performance.

15. Site Architecture: Building an SEO-Friendly Structure

Why Site Architecture Matters

Improves crawlability.
Helps users navigate your site easily.
Ensures important pages get more link equity.

Best Practices for Site Architecture

✅ Use a flat structure (keep pages within 3 clicks of the homepage).
