1. What is SEO?

SEO (Search Engine Optimization), or organic search, refers to the set of techniques used to improve a website's visibility in Google and other search engine results.

The 3 pillars of SEO

2. Conducting a Complete SEO Audit

A professional SEO audit is the first step to identifying improvement opportunities and technical issues hurting your rankings.

Technical audit

• Crawlability: check that Google can crawl all your important pages
• Indexing: use Google Search Console to see indexed pages
• Load speed: test with PageSpeed Insights (target: <2.5s LCP)
• Mobile-friendly: test mobile compatibility (Google Mobile-Friendly Test)
• HTTPS: make sure your site uses SSL
• XML sitemap: create and submit your sitemap to Google
• robots.txt file: check it doesn't block important pages
• 404 errors: identify and fix broken links

Content audit

• Duplicate content: detect and eliminate duplicate content
• Title tags: check every page has a unique, optimized title (50-60 characters)
• Meta descriptions: write compelling descriptions (150-160 characters)
• Hn tags: ensure a logical heading hierarchy (H1 > H2 > H3)
• Content quality: assess depth, originality and added value
• Images: optimize file size and add descriptive alt attributes

Backlink audit

Analyze your backlink profile with tools like Ahrefs, SEMrush or Majestic. Identify toxic links to disavow and opportunities for quality link building.

3. Keyword Research and Strategy

Understanding search intent

Keyword research methodology

1. Initial brainstorming: list the terms your potential customers use
2. Use tools: Google Keyword Planner, Ubersuggest, AnswerThePublic, SEMrush

4. Technical SEO and Core Web Vitals

Core Web Vitals: the essential metrics

Optimal technical structure

Link building (acquiring backlinks) remains one of Google's most important ranking factors. But be careful: quality matters more than quantity.

Create monthly SEO reports to track your progress: traffic evolution, newly ranked keywords, backlinks acquired, technical improvements, ROI of SEO actions. Use Google Data Studio for automated dashboards.
