Real Results: Before vs After

Real Case 1: John's Blog (fitness niche) - BEFORE

❌ Duplicate H1

❌ Meta description: 28 characters (cut off on mobile)

❌ 17 images without alt text

❌ Empty page title

Organic Traffic Analysis: 1,200 visits/month

Fixing Errors with WordPress

❌ Duplicate H1

🔍 What does it mean

Your page has more than one<h1> , usually because:

• The post title is already an H1

• The theme adds another H1 (logo, hero, builder, etc.)

👉 Google doesn't penalize , but it confuses the hierarchy .

✅ How to fix it

• Option A (recommended)

Leave only 1 H1 = content title

1. Edit the page/post

2. Make sure that:

   • The title is the only H1

   • The content begins with H2

In the editor:

Title → H1 (automatic) Subtitles → H2, H3

• Option B (the topic duplicates the H1)

Very common with Elementor, Astra, etc.

Solutions:

• Hide the topic title:

  • Appearance → Customize → Layout → Page Title → OFF

• In Elementor:

  • Page settings → “Hide Title”

👉 This way, the H1 only remains in your content.

❌ Meta description: 28 caracteres

🔍 What does it mean

The meta description is too short .
On mobile, Google usually displays:

• 120–140 characters

✅ How to fix it (Install Yoast / RankMath Plugins)

1. Edit the page

2. Download the SEO plugin

3. Write a meta description for:

   • 130–155 characters

   • Your description + keyword

   • Use the plugin's mobile preview

❌ 17 images without alt text

✅ How to fix it quickly

• Method 1 (manual but correct)

1. Media → Library

2. Select an image

3. Alternative text field

4. Describe the image (NO keyword stuffing)

• Method 2 (fast for many images)

Recommended plugins:

• Media Cloud

• Auto Image Alt Attribute

• SEO Friendly Images

👉 You can generate:

• Alt = post name + description

⚠️ Manually review important images.

❌ Empty page title

🔍 What does it mean

Your <title>(what appears on Google) is empty or poorly defined.

Common cause:

• Page created without a title

• SEO plugin misconfigured

• Special template (landing, home)

✅ How to fix it

• With SEO plugin (recommended): Yoast / RankMath:

1. Edit the page

2. Define SEO Title

Real Case 2: Travel Blog - BEFORE

Errors found using Lookkle's SEO analysis tool :

❌ 9 broken internal links

❌ Duplicate canonical tags

❌ 5 pages without meta descriptions

Tráfico: 890 visitas/mes

Travel Blog - Repair

❌ 9 broken internal links

• Method 1 (recommended). Use a plugin only to detect and correct

Reliable plugins:

• Broken Link Checker

• RankMath → Status & Errors

• Lookkle Broken Link Checker

Steps:

1. Detects the 9 broken links

2. For each link:

   • Correct the URL

   • Or it points to an equivalent page

   • Or delete it if it doesn't add value.

⚠️ Don't leave broken links "because they redirect", Google still sees them as wrong.

Method 2 (manual)

1. Copy the URL with the error

2. Go to the page that contains the link

3. Correct the link in the editor

❌ Canonical Duplicates

🔍 What it means: Google sees more than one canonical tag on the same page. The meta canonical tag should correctly indicate the page you are actually on, but there are cases where this doesn't happen.

Example:

My current page is https://example.com/page/ but the canonical tags might be the following, so there's a serious error:

<link rel="canonical" href="https://example.com/pagina/" />

<link rel="canonical" href="https://example.com/pagina?utm=123" />

👉 This is serious , because Google doesn't know which one to index.

Common causes:

• Two active SEO plugins (Yoast + RankMath)

• The theme adds canonical

• Cache plugin adds canonical

• Elementor / WooCommerce + SEO

✅ How to fix it (step by step):

1️⃣ Check SEO plugins

⚠️ There should ONLY be 1 active SEO plugin

Deactivate:

• Yoast / RankMath / All in One SEO

2️⃣ Check if the theme generates a canonical

Search in header.php:

rel="canonical"

If it exists:
➡️ Deactivate it from the theme panel
➡️ Or let the SEO plugin control it

3️⃣ RankMath / Yoast

Make sure that:

• Canonical is enabled

• It is not manually overwritten.

En RankMath:

Titles & Meta → Global Meta → Canonical

4️⃣ WooCommerce (and apply)

WooCommerce can duplicate canonical tags in:

• Products

• Categories

Solution:

• RankMath → WooCommerce → Canonical ON
