What is SEO
SEO (Search Engine Optimization) is the process of optimizing your website to achieve better rankings in search engine results pages (SERPs) and sustainable organic traffic. It includes on-page, technical and off-page optimization with a focus on search intent, user experience and authority (backlinks).
How SEO works

- On-page optimization: titles, meta descriptions, headings, internal linking, schema markup.
- Technical SEO: speed, Core Web Vitals, crawling and indexing, structure, sitemap, robots.
- Valuable content: topic clusters, guides, studies, optimized category pages.
- Authority and E-E-A-T: quality link building, citations (local SEO), reviews.
SEO advantage
- Zero cost per click in organic traffic (but investment in content and tech).
- Scalability and compound effect: increases in the medium to long term.
- Higher trust: users perceive organic results as more „natural”.
- Coverage on informational, commercial and transactional searches.
SEO limitations
- Time to results: weeks to months.
- High competitiveness on short keywords; requires strategy and consistency.
- Algorithms change; require continuous monitoring and adaptation.

PPC limitations
- Costs rise in competitive markets; CPC fluctuates.
- Traffic disappears when you stop the budget.

Which channel brings faster results?
Short answer: PPC brings faster results. You can generate views and clicks in the same day, and the first conversions usually occur within the first 72 hours, especially in niches with high transactional intent. SEO delivers slower results, but with compound impact and low marginal cost in the long run.
Nuanced answer: there are „quick wins” including in SEO that can visibly accelerate results in a matter of weeks:
- Optimize existing pages with impressions but low CTR (titles/meta and rich snippets).
- Core Web Vitals, correct indexing, fixing major technical errors.
- Long-tail targeting with specific content (guides, comparisons, „near me” for local SEO).
- Strategic internal linking to pages with commercial intent.
- Implement markup schema for reviews, FAQ and product to increase CTR.
Costs, KPIs and ROI - how to measure correctly
KPIs for SEO
- Priority keyword positions and share of voice.
- Organic non-brand traffic and sessions from commercial landing pages.
- Conversions assimilated to organic attribute (leads, sales, MQL).
- Quality: time on page, bounce rate, pages/session, engagement.
KPIs for PPC
- CPC, CTR and Quality Score.
- CPA (cost per acquisition) and ROAS (return on ad spend).
- Conversion rate per campaign/ad group/landing page.
- Impressions, impression share, average position, assisted conversions.

Frequently Asked Questions
Is SEO free?
Organic traffic has no cost per click, but SEO requires investment in content, technical and tools. Cost per acquisition decreases over time if you have a good strategy.
Is it worth bidding on brand words if they're already on top organically?
Often yes. Branded ads protect against competitors, increase message control and can improve overall CTR on the SERP.
Can I stop PPC when SEO starts bringing traffic?
You can reduce your budget or move it to remarketing campaigns and new terms. A flexible mix tends to bring better ROI.
What's the best channel for fast results?
PPC is faster. However, start an SEO plan in parallel to reduce long-term costs and build authority.
The difference between SEO and PPC comes down to pace, cost and sustainability. PPC gets you faster results - visibility and conversions in hours or days - and is ideal for launches, seasonality and rapid message testing. SEO is your long-term growth engine: it builds trust, reduces cost per acquisition and creates a sustainable competitive advantage.
The best answer, in practice, is a mixed strategy: use PPC for speed and validation, while constantly investing in SEO optimization, content and user experience. This will give you both „fast results” and a stable channel to sustain your growth even when budgets fluctuate.
