SEO ajansı ne iş yapar, 2026'da neyi değişti?

SEO ajansı, web sitenin Google ve diğer arama motorlarında üst sıralarda görünmesini sağlayan teknik ve stratejik çalışmaları yürütür. 2026'da modern SEO ajansı sadece Google ile sınırlı kalmıyor: Google AI Overview, ChatGPT, Claude, Perplexity gibi LLM tabanlı arama motorlarında da markanın görünmesini hedefleyen GEO (Generative Engine Optimization) çalışmaları yapar.

GEO (Generative Engine Optimization) nedir, SEO'dan farkı ne?

GEO markanın ChatGPT, Claude, Perplexity, Google AI Overview gibi LLM tabanlı arama motorlarında doğru ve sık alıntılanmasını sağlayan optimizasyon disiplinidir. Klasik SEO Google'da '10 mavi link' arasında üst sırada yer almayı hedefler. GEO ise AI'ın 'cevap' olarak verdiği özette markanın yer almasını hedefler.

SEO ajansı fiyatları 2026'da ne kadar?

SEO hizmeti fiyatları sitenin durumuna, sektör rekabetine ve hedef anahtar kelime zorluğuna göre değişir. 2026 Türkiye pazarında: tek seferlik SEO audit 8.000-15.000 TL, küçük işletme aylık SEO 13.000-20.000 TL, KOBİ orta seviye 20.000-40.000 TL, e-ticaret veya yüksek rekabet 40.000-100.000 TL bandında. AI SEO + GEO ek modül yaklaşık %30 ek hesaplanır.

SEO sonuçları ne kadar sürede gelir?

SEO uzun vadeli bir yatırımdır. İlk anlamlı sonuçlar 3 ay sonra görülmeye başlar, tam etki 6-12 ayda oluşur. GEO citation'lar daha hızlı gelebilir - LLM'lerin (büyük dil modellerinin) index'lemesi haftalar mertebesinde. Rekabet düzeyine ve mevcut site otoritesine göre değişir.

En iyi SEO ajansını nasıl seçmeli?

Beş kritik kriter: AI SEO + GEO yapıyor mu, sektörde gerçek case study var mı, aylık raporlamada organik trafik + keyword sıralama + GEO citation + dönüşüm metrikleri var mı, sözleşme süresi makul mu (3-6 ay test peri), tek nokta hesap verebilirlik mi yoksa hesap yöneticisi sürekli değişiyor mu?

Definition

SEO is no longer enough alone: GEO has entered the scene.

An SEO agency carries out the technical and strategic work to make your website rank higher in search engines. Traditional SEO targets a top position among Google's 10 blue links. In 2026, this is not enough.

GEO (Generative Engine Optimization) is a new optimization discipline that ensures your brand is accurately and frequently cited in AI-based search engines like ChatGPT, Claude, Perplexity and Google AI Overview. More than 40% of users now ask an LLM first. SEO without GEO is incomplete.

A modern SEO agency works in parallel on three fronts: classical Google SERP, Google AI Overview and LLM citation. Brands that are visible on all three fronts capture the highest share of organic traffic in 2026. GEO frameworks like Vasco and Arvo, Schema.org JSON-LD structured data and E-E-A-T signals are the default standards.

Frequently Asked

Answers before you decide.

An SEO agency carries out the technical and strategic work that makes your website rank higher in Google and other search engines. The scope covers technical SEO audit, content strategy, keyword research, backlink strategy, schema markup and performance optimization. In 2026, a modern SEO agency is not limited to Google: it also does GEO (Generative Engine Optimization) work to make your brand visible in LLM-based search engines such as Google AI Overview, ChatGPT, Claude and Perplexity. More than 40% of users now ask an AI assistant first; an SEO agency must work in parallel on three fronts to meet this new reality: classical Google SERP, AI Overview and LLM citation. Brands not visible on all three fronts lose a significant share of 2026 organic traffic.

GEO (Generative Engine Optimization) is a new optimization discipline that ensures your brand is accurately and frequently cited in LLM-based search engines such as ChatGPT, Claude, Perplexity and Google AI Overview. Classical SEO targets a top spot among Google's 10 blue links. GEO targets your brand appearing in the direct answer summary that AI provides. The two approaches complement each other rather than replace each other. Critical signals for GEO: Schema.org JSON-LD structured data, Speakable schema, 134-167 word fact-rich citability blocks, direct-answer formatted paragraphs, entity clarity, current date, authoritative source references, topical authority clusters and author info (E-E-A-T). SEMrush GEO research forecasts AI search traffic will reach 25-40% of organic traffic in 2026.

SEO agency prices in 2026 can be evaluated in three tiers. A one-time comprehensive SEO + GEO audit report starts at 8,000 TL; it includes technical analysis, competitive benchmarking, keyword opportunities, AI Overview and LLM citation scan, and Core Web Vitals report. A monthly SEO + content package starts at 13,000 TL; it includes continuous technical maintenance, 4-8 monthly fact-rich articles, keyword rank tracking and monthly performance report. The Premium SEO + GEO tier is custom quoted; it includes classical SEO + GEO + AI Overview triple optimization, ChatGPT/Claude/Perplexity citation tracking and monthly iteration. In the Turkish market, average budget for similar quality SEO work is in the 15,000-50,000 TL range, and 50,000-100,000 TL for high-competition sectors. Ad spend is separate from SEO budget.

SEO is a long-term investment requiring patience. The first meaningful results usually appear after 3 months; full impact occurs in 6-12 months. The duration depends on competition level, existing site authority, content production pace and technical foundation. The GEO citation side yields faster results than classical SEO: LLMs (large language models) index new content in a matter of weeks. Initial indexing via Google Search Console usually completes in 1-2 weeks, ranking improvement starts 2-4 weeks later. From day one you see transparently what is being done and how it is progressing; monthly reports detail rank tracker, organic traffic, GEO citation count and conversion metrics.

There are five critical criteria for choosing the best SEO agency. First, does the agency do AI SEO and GEO work; in 2026 classical Google SEO alone is not enough, a strategy without ChatGPT and Perplexity citations is incomplete. Second, are there real case studies and measurable results in your sector; generic promises should be avoided. Third, what metrics are in the monthly report; organic traffic, keyword ranking, GEO citation and conversion metrics are all required. Fourth, is the contract duration reasonable; 3-6 month test period is healthy, long penalty clauses should be avoided. Fifth, is there single-point accountability or does the account manager keep changing. In Turkey, the best SEO agencies are usually large-scale but individual specialists offer the advantage of single-point accountability and direct communication.
