The four pillars of modern SEO

What an enterprise SEO company actually delivers in 2026

Technical SEO

Core Web Vitals engineering (LCP, INP, CLS), indexation strategy, structured data (Schema.org JSON-LD), site architecture, internal link graphs, Core Web Vitals monitoring. Our own site scores 96 on mobile Lighthouse — we eat what we cook.

Content & On-Page

Topic cluster strategy, pillar pages, programmatic SEO at scale (state × service combinations), conversion-optimized copy, FAQ schema rollout, glossary entries that earn LLM citations.

Off-Page & Authority

Backlink earning via free tools (CAC calculator, AI Search Audit), PR, podcast guesting, HARO responses, directory submissions. Quality over volume — we build links worth defending.

AI Search Optimization (GEO)

The newest pillar. llms.txt, llms-full.txt, AI bot allowlist (32 crawlers), conversational answer paragraphs, comprehensive Schema.org markup, citation-worthy original research. We rank in ChatGPT, Claude, Perplexity, and Gemini — not just Google.

SEO company FAQ

What does an enterprise SEO company do?

An enterprise SEO company delivers technical SEO, content strategy, link earning, and (in 2026) AI search optimization (GEO/AISO) — making your site rank in both traditional Google search and AI assistants like ChatGPT, Claude, Perplexity, and Gemini. Empire325's SEO practice combines all four pillars with measurement frameworks tied directly to revenue, not vanity metrics.

How much does enterprise SEO cost?

Empire325's SEO engagements typically range from $10K-$60K monthly retainers depending on scope, content velocity, and technical complexity. We provide written scoping after a 30-minute discovery call. Most engagements show measurable ranking improvements within 60-90 days.

How is Empire325 different from other SEO companies?

Three differences: (1) We treat AI search optimization (ChatGPT/Claude/Perplexity citations) as core, not an add-on. (2) Senior practitioners deliver every engagement directly — no junior dilution. (3) Engagements are tied to revenue measurement (MMM, incrementality), not just ranking screenshots.

Do you do local SEO?

Yes. Empire325 is headquartered on Long Island, NY (West Babylon area, Suffolk County). We deliver local SEO for businesses across all 50 US states with state-specific and city-specific landing page programs.

What industries do you serve?

Empire325's SEO clients span SaaS, e-commerce, financial services (private equity, real estate funds, asset management), public-market companies, healthcare, and regulated industries. $47M+ in revenue has been generated for enterprise clients across these sectors.

How long does SEO take to work?

First measurable wins (improved Core Web Vitals, indexation expansion, schema rich-snippet eligibility) typically appear within 30-45 days. Meaningful ranking movement on competitive head terms takes 90-180 days. Compounding traffic growth typically appears in months 6-12 as content and backlinks compound.

Looking for an SEO company you can defend to your CFO?
