What our audit analyzes

On-Page SEO

Master the optimization of every element on your pages to improve your ranking in Google search results.

What is On-Page SEO?

On-Page SEO (or on-site SEO) refers to all optimization techniques applied directly to your website pages. Unlike off-page SEO (backlinks, social media), on-page SEO focuses on elements you fully control.

It's the foundation of any successful SEO strategy. Without good on-page optimization, even the best backlinks won't compensate for content and technical structure gaps.

Key On-Page SEO Elements

T

Title Tag (SEO Title)

The <title> tag is the most important SEO element of your page. It's the blue clickable title that appears in Google results.

Code example:

<title>Website Creation Paris | Expert Web Agency</title>

Best practices:

  • 50-60 characters maximum to avoid truncation
  • Place the main keyword at the beginning of the title
  • Each page must have a unique title
  • Include your brand at the end if relevant
M

Meta Description

The meta description is the text displayed below the title in Google results. While it doesn't directly influence ranking, it strongly impacts click-through rate (CTR).

Code example:

<meta name="description" content="Paris web agency specializing in website creation. Free quote within 24h.">

Best practices:

  • 120-160 characters for optimal display
  • Include a call-to-action (CTA)
  • Summarize the page content in an attractive way
H

Heading Structure (H1-H6)

The heading hierarchy helps Google understand your content's structure and organization. Good structure also improves accessibility and user experience.

Ideal structure:

H1: Main title (unique)

H2: Main section

H3: Subsection

H2: Another main section

H3: Subsection

Best practices:

  • Only one H1 per page
  • Follow logical hierarchy (no H4 without H3)
  • Include relevant keywords in your headings

Canonical URL

The canonical tag tells Google which is the "official" version of a page, thus avoiding duplicate content issues.

Code example:

<link rel="canonical" href="https://www.mysite.com/official-page">

When to use:

  • Pages accessible via multiple URLs
  • Similar content on different pages
  • URL parameters (filters, tracking)

Hreflang Tags

Hreflang tags tell Google about different language or regional versions of your content, essential for multilingual websites.

Code example:

<link rel="alternate" hreflang="fr" href="https://www.mysite.com/page"> <link rel="alternate" hreflang="en" href="https://www.mysite.com/en/page"> <link rel="alternate" hreflang="x-default" href="https://www.mysite.com/page">

Best practices:

  • Always include x-default as fallback
  • Links must be reciprocal
  • Use ISO 639-1 codes for languages
