Google Ads vs. SEO: why SEO is the more sustainable strategy

By Karim Hadj Yahia ·

Introduction

Many businesses face the question: Google Ads or SEO? Both methods have advantages and disadvantages. But which strategy pays off in the long run? Spoiler: SEO is more sustainable and delivers more ROI in the long term.

What is Google Ads?

Definition: Paid ads that appear in Google search results.

How does it work?

  • You pay per click (PPC: pay per click).
  • As soon as the budget is used up, your ad disappears.
  • High competition can drive up click prices (CPCs) → rising costs.
  • Google offers various ad formats: search ads, display ads, video ads and Shopping ads.
  • Click prices vary by industry and level of competition.
  • You can show ads to specific audiences and in specific locations.

Advantages of Google Ads

  • Fast results: Ads are visible immediately.
  • Precise targeting: You can show your ads specifically to interested prospects.
  • Measurability: All clicks, conversions and impressions can be analysed precisely.

Disadvantages of Google Ads

  • High costs: You pay for every click.
  • No sustainability: When the budget runs out, your visibility disappears.
  • Growing competition: In many industries, CPCs rise every year.

What is SEO?

Definition: Optimising your website for free, organic Google traffic.

How does it work?

Advantages of SEO

  • No click costs: Organic traffic is free.
  • Lasting impact: Good rankings can last for years.
  • Greater trust: Users are more likely to click on organic results than on ads.

Disadvantages of SEO

  • Slow results: The first successes often only show after months.
  • Constant competition: Competitors are also optimising for better rankings.
  • Regular maintenance needed: Algorithms change constantly, so continuous optimisation is important.

Why SEO is the more sustainable strategy

SEO visibility grows over time

  • Ads stop immediately when you stop paying.
  • SEO can keep growing over time.
  • Older pages with many backlinks often rank steadily for years.
  • Good content can provide stable revenue in the long term.

Higher click-through rate than Google Ads

  • The top 3 organic results get over 50% of clicks.
  • Users trust organic results more than ads.
  • In the long term, SEO generates more qualified leads than Google Ads.

SEO protects you from rising advertising costs

  • Google Ads gets more expensive every year.
