Top 8 Genuine SEO Companies on Long Island, NY — Verified 2026

Last updated: September 2026

A widely-circulated "Top 10 Long Island SEO Companies" list turned out to be a good case study in why a name alone isn't proof of a real local office. Independently re-verifying all ten names on it found that only two survive as genuine Nassau or Suffolk County businesses.

The single worst example: one agency's homepage claims “offices in NYC & Long Island” with no specifics, and third-party directories point to an address in Commack, NY. Real-estate records for that address — a four-bedroom, two-bath, 2,059-square-foot house — show it's zoned single-family residential, not commercial. A top-ranked “Long Island SEO company” turned out, according to public property records, to be somebody's house.

This guide checked more than twenty agencies surfacing for “Long Island SEO company” against three questions: is there a real, staffed office inside Nassau or Suffolk County; does independent evidence back that up; and does the agency actually name SEO as a service. Eight cleared every check. Here they are, along with a full accounting of what happened to the names that didn't.

Why Long Island's SEO Market Is Distinct

Long Island isn't a suburb of New York City in the way most people use that word — for this guide, and for the businesses on it, it means Nassau and Suffolk counties specifically, not Brooklyn or Queens, which sit on the same landmass but are New York City boroughs with their own separate business identity. That's a market of well over 2.8 million people that's affluent, densely populated, and genuinely separate from Manhattan's. Nassau County alone has some of the highest median household incomes of any county in the country, which shapes what local SEO looks like here: home-services and medical-practice competition is fierce, franchise and healthcare marketing budgets run larger than in most metro areas, and search intent skews toward high-consideration purchases — a new roof, a cosmetic dental practice, a personal-injury attorney — rather than tourist-season spikes.

That density also means the agency landscape here has its own centers of gravity: Melville and Hauppauge for larger firms with office-park space, the Route 25/Main Street corridors of Port Jefferson, Holbrook, and Smithtown for smaller specialist shops, and a scattering of home-based operators serving a single town. None of that is Manhattan's agency scene, and treating “New York SEO” and “Long Island SEO” as interchangeable is exactly the confusion the competitor's list traded on.

It's also worth being precise about geography, because the name itself causes mix-ups. Long Island City, despite the name, is in Queens — part of New York City proper, not Nassau or Suffolk — and at least one agency on this list's exclusion pile leans on that confusion. A genuine Long Island SEO company has a street address an employer could drive to inside the actual island's two easternmost counties, not a landing page built around the keyword.

Quick Comparison

None of the eight publish a rate card. Every quote below is what each agency itself confirms is custom — get a written scope and monthly minimum before signing anything.

A few numbers ground why this market deserves its own list rather than a generic “New York” roundup. U.S. Census Bureau data puts Nassau and Suffolk combined at well over 2.8 million residents on their own, with household incomes among the highest of any counties in the country. Long Island Business News covers this market as its own distinct economy, separate from Manhattan trade press, and Newsday's business coverage reflects the same split — a further sign that treating “Long Island” and “New York City” as interchangeable, the way the excluded competitor list effectively did, misreads the market these agencies actually serve.

1. EGC Group

EGC Group has run out of Melville, NY since Ernest G. Canadeo founded it in 1985 (incorporated with New York in January 1986, DOS #1048642, per state filing records referenced by opengovny.com), which makes it the oldest agency on this list by a wide margin and the strongest Tier A candidate independently. Its Walt Whitman Road office is confirmed by the Better Business Bureau, and a second office in Brooklyn extends its reach into New York City without replacing the Long Island headquarters.

The client roster on its own homepage — Catholic Health, Mayo Clinic, Dental365, Canon, Thomson Reuters, Sterling Optical, CityMD, Vaughn College — is enterprise-and-healthcare-heavy, which tells you the scale this agency is built for. It organizes work into three named tracks (research and brand strategy, growth channels including SEO and paid search, and conversion work like web development and CRM), rather than folding everything into one generic “digital marketing” bucket.

Best fit for: a healthcare system, retail franchise, or enterprise brand that wants a 40-year Long Island agency with big-client experience, not a small-business generalist.

Pricing: custom quote; no published rate card, and retainer minimums are likely higher given the client roster.

2. Hozio

Hozio operates from 5439 Sunrise Highway in Holbrook, and unlike some multi-office agencies on this list, its own homepage leads with the Long Island phone number (631-750-6295) at the top of every page rather than burying it behind a contact form. The site cites 550+ businesses served, a 4.8-star rating, and over 100 Google reviews; one client testimonial states they've worked with Hozio for “over 8 years,” which is the only independent age signal available since Hozio doesn't publish a founding date.

Hozio also lists a New York City office on Lexington Avenue, so this is a two-office operation rather than a Long Island exclusive — but the 631 area code leading every page, combined with the client-tenure testimonial, is stronger evidence of an actively staffed Holbrook location than a single directory listing would be.

Best fit for: a business wanting a mid-size agency with SEO, AI-search, and web-design services under one roof and a dedicated Long Island contact number.

Pricing: custom proposal; the site states cost “varies and depends on your unique needs,” with customizable packages.

3. Benjamin Marc

Benjamin Marc was founded in 2005 by Anthony Savino and works out of 36 Terry Road in Smithtown — a claim its own homepage backs up literally, with a drone-shot hero video of the actual office building (drone photography is one of its listed services, so the flex is on-brand). Google reviews embedded on the site show a perfect 5.0 rating across 269 reviews, one of the strongest review counts of any agency on this list.

SEO sits alongside web design, logo and brand work, and physical screen printing and promotional items — an unusual combination that suggests a shop built for small Long Island businesses that want one vendor for both their website and their branded merchandise, not a pure-play SEO specialist.

Best fit for: a small business that wants web design, branding, SEO, and printed promotional materials handled by a single local shop.

Pricing: described on-site as “reasonable” and “affordable” for small business budgets; no rate card published.

4. UnReal Web Marketing

UnReal Web Marketing has worked from 414 Main Street in Port Jefferson since 1997, and its homepage banner claims “25 Years of Experience” as a Long Island SEO agency — the longest continuously operating dedicated SEO shop on this list. Badges on the homepage include Google Partner status, an Expertise.com “Best SEO Experts” award, and an Inc. 5000 listing.

The disclosure worth making plainly: the site's footer identifies UnReal as “A Reach Marketing Company,” meaning it operates under a larger marketing holding company rather than as a fully independent shop. Available sources describe it as remaining a separate operating company under that ownership, but a prospective client should ask directly who they'd actually be contracting with.

Best fit for: a business that wants a specialist SEO shop (not a general-purpose agency) with the longest track record in the area and the resources of a larger parent company behind it.

Pricing: custom SEO packages; a dedicated packages page exists but figures aren't published without a consultation.

5. fishbat

fishbat lists a genuine Long Island office at 407 Main Street, Suite 7, in Port Jefferson, alongside a Manhattan office on Madison Avenue and a third location in Wilmington, North Carolina. The company took its current name in 2009 and offers strategy, UX and interactive design, digital advertising, and content marketing as four named service tracks.

Two honest caveats. A 2013 press release independently confirmed a second Long Island address at 25 Orville Drive in Bohemia, but that location no longer appears on the current site, suggesting the Bohemia office was consolidated at some point. And the current homepage's own vertical sidebar text reads “NEW YORK DIGITAL MARKETING AGENCY” — a signal the brand now positions itself primarily as an NYC firm, even though Port Jefferson remains a real, listed address today.

Best fit for: a brand that wants NYC-caliber creative and advertising capability from an agency that still keeps a genuine Port Jefferson office.

Pricing: free consultation via phone; custom quote, no published rate card.

6. Lounge Lizard

Lounge Lizard was founded in 1998 by Ken Braun and has grown into a national agency with offices in Washington D.C., Nashville, Miami, Charleston, Richmond, Las Vegas, and Austin, in addition to Manhattan and Long Island. Independent directory listings (Agency Spotter, Yelp) confirm a real Holbrook, NY branch at 991 Main Street, Suite 200, with its own dedicated phone line separate from the Manhattan switchboard — consistent with how its other genuine branch offices are set up.

The disclosure here is the most important thing to know before reaching out: the homepage itself brands the company as a “New York Web Design Company & Digital Marketing Agency Since 1998” with no mention of Long Island above the fold. The Holbrook office is real, but it is not the flagship, and a Long Island client should ask directly whether their account will actually be staffed from that branch or from Manhattan.

Best fit for: a business that wants a large, award-recognized national agency and is comfortable with the account potentially running through Manhattan rather than the local branch.

Pricing: free growth-strategy consultation; custom proposal, no published rate card.

7. Local Media Solutions

Local Media Solutions works from 175 Broadhollow Road, Suite 168, in Melville, and its own site claims “over 25 years of local advertising experience.” Reviews on Yelp and Birdeye (240+) back up an active, ongoing client base, and the company is transparent about being a Google Premier Partner.

Worth disclosing plainly: the Broadhollow Road address is a shared executive-suite building, not a standalone office — the kind of setup that's common for small local-marketing firms and isn't disqualifying on its own, but it does mean the address alone proves less than a dedicated storefront would. This is also the one agency on this list that publishes an actual promotional discount — $250 off the first month's bill, or 25% off with a six-month commitment (three-month minimum) — on its own homepage rather than hiding all pricing behind a form.

Best fit for: a small business that wants simple, bundled local packages — SEO plus Google Business Profile plus text/QR marketing — from a Long Island-based team.

Pricing: published introductory discounts ($250 off month one, or 25% off a 6-month term); full package pricing is otherwise custom.

8. SEO Long Island

SEO Long Island operates from 275 Marcus Boulevard in Hauppauge, an address confirmed independently through Yelp, Facebook, and Datanyze. The homepage self-reports “8+ years in business,” 150+ local businesses ranked, and a 3x average traffic increase — figures that come from the agency itself rather than a third-party audit, so treat them as a starting point for questions rather than settled fact.

Unlike most of the boutiques on this list, SEO Long Island leads its homepage with AI and generative-engine optimization as a current, active offering rather than an afterthought, positioning itself for businesses specifically worried about visibility inside AI answer tools rather than just classic Google rankings.

Best fit for: a business that wants a boutique, Hauppauge-based SEO shop already built around AI-search visibility rather than search-engine rankings alone.

Pricing: free SEO audit offered; custom pricing beyond that, no rate card published.

How These Agencies Were Chosen

Every agency had to clear three checks: a real, staffed office physically inside Nassau or Suffolk County, not a service-area landing page; independent corroboration from at least one source beyond the agency's own website — Google Business Profile, Yelp, a directory listing, a press mention, or state incorporation records; and SEO named as an actual service rather than buried inside vague “digital marketing” copy. More than twenty names were reviewed in total, including all ten from the competitor list this guide opened with.

Of that competitor's ten picks, only fishbat and Lounge Lizard survived independent re-verification, and both needed a caveat disclosed above: fishbat's own site now brands itself primarily as an NYC agency, and Lounge Lizard's Long Island branch is real but is not the flagship office. The other eight did not hold up, for four distinct kinds of reasons.

Three were simply the wrong state. Mediaboom's confirmed headquarters is in Guilford, Connecticut, with no New York presence anywhere. Coalition Technologies is headquartered at 515 S Flower Street in Los Angeles, with no NY or Long Island office found in any record. SmartSites' one confirmed office, per Craft.co, is in Paramus, New Jersey — no Long Island branch exists. Linear Design's link on the competitor's own page goes to a Utah-based PPC and CRO agency whose own site literally says it was “made with love in Utah,” with zero mention of New York; this looks like either a fabricated entry or a broken link on the competitor's own page.

One was the publisher of the very list this research started from — a Manhattan agency that had ranked itself #2 in its own "Top 10" despite having no independently verifiable Nassau or Suffolk address anywhere on its own site.

One was a dead domain standing in for an entire business. One listed agency's own domain returns a DNS failure — it doesn't resolve at all. No business by that name serving Long Island turned up on Yelp, BBB, Facebook, or general search. In a “Top 10” list, a broken link to a nonexistent business is a serious quality failure, not a minor oversight.

One was the residential-address finding that anchors this entire guide: an agency ranked #1 on the original list, whose own homepage vaguely claims “offices in NYC & Long Island” with no address, while third-party listings point to 6 Parkway Drive South in Commack — a property that real-estate records from Movoto and Coldwell Banker confirm is a single-family residential home, not commercial office space.

The last, LongIslandSEO.Agency, had no street address, founder name, registered entity, or independent listing on Yelp, BBB, Clutch, or DesignRush anywhere — just generic marketing copy on a templated page, with no verifiable identity behind it at all.

Three genuinely Long Island-based candidates found independently were also left off, each for a stated reason rather than being forced onto the list. Design ME Marketing in Deer Park is a real company, but its “Top SEO Company” recognition turned out to be paid, syndicated press-release content — the identical text runs on unrelated local “news” sites in Nebraska and elsewhere, explicitly labeled as sponsored or advertising content rather than independent journalism. Island Web Solutions in Oceanside appears to be a genuine, family-run local firm, but its homepage repeatedly crashed an independent headless-browser check across multiple attempts and configurations, so it could not be screenshot-verified and was left off rather than represented with a substitute image. THE LONG ISLAND SEO COMPANY has a real, Yelp-confirmed address and phone number at 11 Sheer Plaza in Plainview, but no independently identifiable company website could be found anywhere to verify or screenshot, so it was excluded rather than guessed at.

One more name is worth a mention as a naming-confusion trap rather than a candidate: Long Island Local SEO, at 34-18 Northern Boulevard, is genuinely a real, reviewed business — but that address is in Long Island City, which is part of Queens in New York City proper, not Nassau or Suffolk County. It's a legitimate company with a name that happens to collide with this list's entire subject.

How These 8 Agencies Compare

• Longest-running agency overall: EGC Group, founded 1985, still Long Island-based.
• Most prominent Long Island phone number and testimonial-backed tenure: Hozio, in Holbrook.
• Strongest independent review count: Benjamin Marc, 269 Google reviews at 5.0 stars.
• Longest-running dedicated SEO specialist: UnReal Web Marketing, since 1997.
• Strongest NYC-caliber creative capacity with a real local office: fishbat, in Port Jefferson.
• Largest national agency with a genuine Long Island branch: Lounge Lizard, out of Holbrook.
• Most transparent published pricing: Local Media Solutions, with a stated introductory discount.
• Only boutique leading with AI/generative-engine SEO: SEO Long Island, in Hauppauge.

What to Check Before Signing With Any of Them

• Verify the address isn't residential — this research found a competitor's #1-ranked pick pointing at someone's actual house; a quick property-records or Google Street View check settles it in minutes
• Ask which office would actually staff your account — several agencies here have a real Long Island branch that isn't the flagship office
• Confirm the entity that will invoice you — a few of these brands operate under a parent company; that's normal, but you should know it going in
• Get the monthly minimum and scope in writing — none of the eight publish a full rate card, so verbal quotes on a sales call aren't binding
• Cross-check any “award” or press mention — this research found one genuine Long Island agency whose “top company” recognition was paid, syndicated press-release content, not independent journalism
• Search the exact street address plus the word “Yelp” or “BBB” before signing anything — a business with zero independent footprint beyond its own homepage is a red flag

The Bottom Line

Long Island's SEO market is real, distinct from Manhattan's, and much smaller than the search results for “Long Island SEO company” suggest once you filter out landing pages and one competitor's self-serving list. EGC Group is the strongest all-around pick by longevity and client roster; Hozio backs up its Holbrook office with the most visible local phone presence; Benjamin Marc and UnReal Web Marketing bring the deepest review count and longest specialist track record respectively; fishbat and Lounge Lizard are both genuine but now lean NYC-first, which is worth knowing going in; and Local Media Solutions and SEO Long Island round things out as transparent, boutique local options.

Whichever you choose, the diligence from this guide travels with you: confirm the office is real and staffed, get the scope and minimum in writing, and never take a “Top 10” list at face value when the publisher ranked itself on it.
