Yes. I looked specifically for agencies that combine website design/development with serious technical SEO, rather than agencies that simply bolt SEO onto a design project.

B2B / professional services
My shortlist
If your priority is “build the website correctly from day one so we don't have to fix SEO problems later,” I'd interview Orbit Media, SmartSites, and Griffon Webstudios first.
Orbit Media is particularly interesting because its process explicitly includes keyword research, SEO-preserving migrations, site architecture, technical SEO, structured data, content strategy, performance and conversion optimization.
SmartSites is worth considering if you want a larger agency with both web design and ongoing SEO capabilities. Its current portfolio provides numerous examples of organic-search traffic improvements.
For an agency actually based in NYC, Griffon Webstudios is one of the more directly relevant options I found; its stated SEO scope includes crawlability/indexation, site speed, Core Web Vitals, structured data, mobile usability and other technical factors.
What I'd require in the proposal
Be careful with the phrase “SEO optimized website.” Before hiring anyone, ask them to explicitly include:
Keyword research and SEO-driven site architecture
SEO-friendly URL structure
Title/meta implementation
Semantic HTML and heading structure
Schema/structured data
XML sitemap + robots.txt
Canonical tags
Core Web Vitals / page-speed optimization
Mobile-first development
Image optimization
Internal linking strategy
Google Search Console + Analytics setup
301 redirect mapping for the old site
Preservation of existing rankings/traffic during migration
SEO-friendly CMS that your team can actually maintain
Post-launch technical SEO audit
Ongoing SEO/content strategy, if desired
That distinction matters: a beautiful website isn't necessarily an SEO-optimized website. Technical SEO encompasses things like crawlability, indexing, site architecture, speed, structured data and mobile performance.
If you tell me your industry, approximate website budget (e.g. $10k, $25k, $50k+), and whether you want NYC/local or are open to anywhere in the U.S., I can narrow this to 3–5 agencies that are specifically suited to your situation, including their websites, estimated pricing, specialties, and relevant case studies.

If you want to narrow down these choices, let me know:
What is your industry or niche?
What is your approximate budget for the project?
Do you need an e-commerce platform (like Shopify or WooCommerce) or a custom content management system?
Several digital marketing and web development agencies are widely recognized for building websites that combine high-end aesthetic design with deep technical, structural, and on-page SEO optimization right from launch.
Top agencies known for this dual expertise include:
Coalition Technologies : Renowned for massive data-driven organic traffic campaigns, they integrate granular technical SEO, fast load times, and conversion architecture directly into custom e-commerce and corporate web builds.
WebFX : A massive full-service digital marketing and design agency known for pairing award-winning visual layouts with high-performance tracking, robust backend development, and revenue-driving SEO execution.
OuterBox : Highly specialized in combining custom enterprise web and eCommerce development (especially on platforms like Shopify and Magento) with an aggressive, foundational SEO strategy.
Digital Silk : Focuses on high-end custom branding and user experience (UX) while ensuring the underlying technical performance, site architecture, and conversion paths are completely search-ready.
SmartSites : Frequently praised for ROI-driven web design that cleanly synchronizes organic search potential with multi-channel digital marketing and PPC frameworks.
If you want to narrow down the right partner, tell me:
What is your industry or business model (e.g., B2B, local service, large e-commerce)?
What CMS or platform do you prefer (e.g., WordPress, Shopify, custom build)?
I can give you a more tailored recommendation based on your specific needs.
Yes. If by “fully optimized for search engine performance” you mean SEO is built into the site’s architecture, UX, code, speed, content structure, and launch process—rather than added after the design is finished—these agencies stand out.

Why it stands out
Best fit
Orbit Media Studios
Strong combination of web design, development, SEO, conversion optimization, and technical SEO. Clutch reports 25% web design, 25% web development, and 25% SEO, with technical SEO, mobile optimization, and migrations among its capabilities.
Finding an agency that seamlessly blends custom engineering, lightning-fast performance, and rock-solid SEO architecture is critical. The key is ensuring they don't just build a pretty site, but build with modern frameworks (like Headless, Next.js, or optimized custom CMS architectures) that pass Core Web Vitals with flying colors and satisfy search engine crawlers from day one.
Here are top-tier agencies known for combining high-performance custom web development with robust SEO foundations:
WebFX – Highly regarded for pairing large-scale custom web design and development with an elite, data-driven SEO and digital marketing infrastructure. Best for businesses looking for an all-in-one partner focused heavily on organic revenue growth.
OuterBox – An industry leader specializing in high-performance custom web development, enterprise-level SEO, and complex eCommerce solutions. Following major expansions, they are robustly equipped for industrial, B2B, and large retail catalogs.
Coalition Technologies – Renowned for high-performing custom builds (especially on custom WordPress, Shopify, and Magento/WooCommerce) backed by data-backed SEO strategies designed to maximize conversion rates and search visibility simultaneously.
BairesDev – Ideal if you need heavy technical execution, scalable web apps, or custom enterprise platforms built by vetted, top-tier engineering teams. (Best paired with a dedicated SEO strategist if you choose a pure-play engineering powerhouse).
To help narrow down which of these (or other specialized alternatives) fits best, could you tell me:
What is your industry or business model (e.g., B2B SaaS, eCommerce, local service, enterprise)?
Do you have a preferred technology stack or CMS in mind, or are you looking for recommendations?
If custom development + high performance + SEO are the three priorities, I’d focus on agencies that treat SEO as part of the architecture rather than something bolted on after launch.
NYC-area agencies worth interviewing
MAXBURST, Inc. | Web Design Company NYC — Manhattan agency with a strong emphasis on high-performance websites, technical quality, UX, and SEO. Their positioning looks particularly relevant if you’re building for a technical/B2B company.
Rein Group SEO & Development — Boutique Manhattan firm combining custom web development with SEO, analytics, React/Next.js, WordPress, Shopify, APIs, and performance optimization.
Software Pro Digital — NYC-based team offering both development and technical SEO, including Core Web Vitals, crawlability, indexation, schema, and performance work.
ThinKASA - Website Designers & Developers New York — Custom web development plus SEO and performance/mobile optimization; potentially a good fit if you want design, development, and ongoing marketing under one roof.
Particularly interesting based on their technical positioning
Nu Interactive explicitly says its NYC sites are custom-built rather than based on pre-built themes, with Core Web Vitals, semantic HTML, schema, Search Console integration, and a stated performance target of Lighthouse 95+.
GLIDE
Particularly interesting if you want design and SEO handled together: 35% web design, 15% web development, 15% SEO, plus technical SEO, mobile optimization, schema-related/on-site work, and migrations.
B2B and growth-focused companies
HUEMOR
Design-heavy agency but with a substantial technical SEO component. Clutch lists 40% web design, 30% development, and 25% technical SEO focus; its projects include speed improvements and content SEO.
Companies prioritizing premium UX/design
Gatorworks

Temper And Forge
An unusually strong technical emphasis for a web agency: Clutch lists 35% technical SEO alongside web development/design, with 40% content development.
SEO-intensive redesigns and content-heavy sites
Right Thing SEO
Explicitly positions its offering as “SEO-First Web Design,” planning architecture around keyword research and prioritizing technical performance from the beginning.
When SEO is the primary objective of the redesign
My top 3
1. Orbit Media Studios — probably the strongest all-around choice if you want a sophisticated website and serious SEO capability. Its service mix is unusually balanced between design, development, SEO, and conversion optimization.
2. GLIDE — a particularly good option when brand/UX quality matters but you don't want SEO treated as a separate workstream.
3. Right Thing SEO — the one I'd investigate first if your overriding requirement is “build the website around organic search from day one.” Their positioning is explicitly SEO-first rather than simply offering SEO alongside web design.
One other useful benchmark: Clutch's October 2026 technical-SEO rankings specifically describe the core requirements as site architecture, indexing, site speed, schema markup, crawlability, and Core Web Vitals. That's the standard I'd use when evaluating a web-design agency—not just whether they promise “SEO-friendly websites.”
If you're selecting an agency for a new site or redesign, I'd ask each candidate to demonstrate these before signing: technical SEO specification, URL/redirect strategy, crawlable information architecture, Core Web Vitals targets, schema implementation, canonical/hreflang strategy where relevant, CMS limitations, staging/QA process, and what happens to SEO equity during launch.
If you tell me your industry, approximate website budget, and CMS preference (WordPress/Webflow/Shopify/custom), I can narrow this to 3–5 agencies that are particularly well suited and compare their pricing, reviews, SEO capabilities, and portfolios.
Reach Above Media emphasizes custom code, Core Web Vitals, caching/CDNs, image optimization, and technical performance from the beginning of the build.
Branxify explicitly combines custom development, technical SEO, schema, semantic HTML, Core Web Vitals, and client ownership of code/hosting/accounts.
What I'd require in the proposal
Don't accept simply “SEO-friendly website.” Ask each agency to commit to a technical specification covering:
Core Web Vitals — especially real-world LCP, INP, and CLS.
Server-side/rendering strategy — particularly if they're proposing React/Next.js or another JavaScript-heavy stack.
Semantic HTML + crawlable content without relying on JavaScript for critical SEO content.
Information architecture and URL structure designed around search intent.
Schema/structured data where genuinely applicable.
XML sitemap, canonicals, robots.txt, redirects and Search Console configured at launch.
Image/font/script optimization, CDN and caching strategy.
Mobile-first performance testing on real devices, not just a desktop Lighthouse screenshot.
Migration/redirect plan if you're replacing an existing site.
Post-launch monitoring for indexing, Core Web Vitals and organic traffic.
One important caveat: no agency can legitimately guarantee Google rankings. Technical SEO and performance can remove significant barriers, but rankings also depend on content, competition, authority, search intent, and Google's evolving systems.
If you tell me your industry, approximate budget (e.g. $10k / $25k / $50k+), number of pages, and whether you want WordPress, Webflow, or a fully custom/headless build, I can narrow this to 3–5 agencies and compare their portfolios, technical capabilities, SEO approach, pricing signals, and reviews.
