Boston has plenty of agencies that say they do SEO and few that clear our bar: we screened 372 businesses, 132 that offer SEO, and five we would list. Fewer than one in four of the 26 that qualified publish a monthly price, and only two rank in Google’s top 10 for the Boston SEO searches we checked. This list comes from a review of the SEO agencies we could find in the Boston metro: what they publish, what they’ve proven, what clients say, and how they rank for their own city.

The short answer For law firms, healthcare and larger B2B budgets, start with Fuel Online. For B2B and manufacturers that also want SEO training, Brick Marketing. For law firms that want published monthly pricing, Up And Social. For a small local or health practice that wants SEO-only pricing, BonBonica. For a website build and SEO from one Massachusetts team, Torro Media.

No agency paid to be listed or can pay to change its position. I run a fractional SEO practice, which some businesses hire instead of an agency, so I don't rank myself here. How we reviewed

The five

The five agencies, reviewed

Top pickBest for law firms, healthcare practices and B2B companies that want a large SEO team

Fuel Online

5.0 on Google (74) · 5.0 on Clutch (21) · Financial District · 90 on LinkedIn

Why we picked them

  • Case studies with figures, such as a Texas B2B software company's demo requests going from 48 to 151 a month in five months.
  • 44 Google reviews read, all 5 stars, and 32 of them cite SEO results; 5.0 on Clutch from 21 reviews.
  • Longest-serving team of the five: median tenure 5.5 years across 90 people on LinkedIn.

What clients say

Reviewers most often credit rankings, organic traffic and leads, and many mention its AI-search work. Hands down the best SEO agency we’ve worked with because they actually delivered — Google reviewer, 2025

Watch-outs

It publishes no price or contract term, and Clutch lists a minimum project of $5,000. Nineteen of its Google reviews fall between January and April 2026 and several read alike, so treat the review count with care. Only about 12 of the 90 people on its LinkedIn page list the US as their location, so ask who will actually do the work. It shares a suite at 101 Federal Street with Brick Marketing, and its homepage claims such as "4.25M+ leads" are unsupported. It doesn't rank in the top 10 for any of the 12 Boston SEO searches we checked (top 20 for two), though it appears in Google's local pack, and AI assistants named it in 7 of 15 answers.

2 · B2B, manufacturing and technology companies that want SEO plus training or consulting

Brick Marketing

5.0 on Google (5) · 5.0 on Clutch (3) · Financial District · 8 on LinkedIn

Why we picked them

  • Top 10 for 6 of the 12 Boston SEO searches we checked, more than any other agency we reviewed.
  • Named in 9 of 15 AI-assistant answers we tested, more than any other agency.
  • Around 40 published case summaries across B2B, manufacturing, construction and healthcare.

What clients say

Reviewers describe clear direction and honest expectations; none of the five Google reviews names an SEO result. They were upfront that results take time and set realistic expectations — Google reviewer, 2026

Watch-outs

Its case summaries are anonymous percentages with no starting figures or dates. It publishes no price or contract term, and Clutch lists a minimum project of $10,000. It has only five Google reviews and three on Clutch, all recent, and the newest Google review comes from a class attendee. LinkedIn shows 8 people with a median tenure of 1.3 years. It shares a suite at 101 Federal Street with Fuel Online.

3 · Law firms that want published monthly SEO pricing

Up And Social

5.0 on Google (62) · No Clutch reviews · South Boston · No LinkedIn page

Why we picked them

  • Published pricing: $1,750, $2,750 and $4,750 a month, in a market where only 6 of 26 qualified agencies publish a price.
  • Case studies with start points, such as an estate-planning firm's Google clicks going from 198 to 928 a quarter between July to September 2025 and the same period in 2026.
  • 43 unique Google reviews read, all 5 stars, and 62 on its profile.

What clients say

Reviewers mostly describe website builds and responsive service; five mention page-one rankings or inquiries. I’m ranking on the first page for several key search terms in my industry — Google reviewer, 2025

Watch-outs

It works with law firms only. Every plan adds a one-time $1,497 activation fee, and it states no contract term. Most reviews are about web design, not SEO, and only five are from the last 12 months. We found no LinkedIn company page, and its Boston address looks residential. It doesn't rank in the top 10 or top 20 for any of the 12 Boston SEO searches we checked, though it appears in Google's local pack, and AI assistants named it in 1 of 15 answers.

4 · Small local and health practices that want SEO-only pricing and reporting

BonBonica

5.0 on Google (12) · No Clutch reviews · Swampscott · 1 on LinkedIn

Why we picked them

  • SEO-only monthly price ranges of $3,000 to $7,000, published on its site.
  • Two case studies with figures, such as a Massachusetts practice reaching 1,180 clicks and 483 keywords at position one in 12 months, from a site with no rankings.
  • 12 Google reviews, all 5 stars, and three cite organic traffic or leads.

What clients say

Reviewers credit plain-language explanations and care, and three describe organic traffic or leads. Within a few months I saw organic traction to our website — Google reviewer, 2026

Watch-outs

It is effectively a one-person firm: LinkedIn shows one employee, and it is a service-area business with no street address (Swampscott). Seven of its 12 Google reviews arrived within 18 days in September 2023, and only one is from the last 12 months. It states no contract term, and its case-study clients are unnamed. It doesn't rank in the top 20 for any of the 12 Boston SEO searches we checked, and AI assistants didn't name it in any of the 15 answers.

5 · Small businesses that want a website build and SEO from one Massachusetts team

Torro Media

5.0 on Google (26) · 5.0 on Clutch (24) · Wilmington · 32 on LinkedIn

Why we picked them

  • Published SEO pricing: "most of our SEO plans start around $1,000/mo".
  • Top 10 for 2 of the 12 Boston SEO searches we checked.
  • 5.0 on Clutch from 24 reviews and 5.0 on Google from 26, with 32 people on LinkedIn.

What clients say

Reviewers mostly praise website work and responsive service; nine mention SEO, mostly without a result. Their SEO support is just as strong. — Google reviewer, 2025

Watch-outs

SEO is one of many services and most reviews are about web design. It publishes no numeric SEO case study (case studies are "on request"), and only one Google review is from the last 12 months. Its "Voted #1 Boston SEO Agency" and Inc. 5000 claims are unverified, and some older reviews date from its earlier name. Its LinkedIn HQ is in Wilmington, with a Boston office at 200 Portland Street. AI assistants named it in 4 of 15 answers.

Before you sign

What we saw that you should watch for

None of these rules an agency out on its own, but each is worth a question before you sign.

  • National firms with a Boston landing page Many agencies ranking for Boston searches are based in other states or countries and have only a "Boston SEO" page. We failed those that showed no office, team or history in the Boston metro.
  • Ranking promises Several Boston agencies promise a first-page result, a top-3 spot on Google Maps, or "if you don't rank, you don't pay". Nobody controls Google's rankings; read what a guarantee actually covers.
  • Bought links A few agencies sell backlink packages for a few hundred dollars or recommend paid link sellers. Paid links break Google's guidelines; ask how links are earned.
  • Results with no baseline Many agencies publish percentages such as "240% organic growth" with no starting figure, date or client name. Ask for the before-and-after numbers and the period.
  • Shared and virtual offices Several Boston addresses are shared suites or mailboxes, and some agencies list the same suite. Ask where the team works and who will handle your account.
  • Review bursts Some profiles gained many reviews within days or weeks. Read the dates and wording, and weigh recent reviews from clients who describe the work.

Method

How we reviewed

Every agency went through the same three rounds, each looking harder at fewer agencies.

  1. Screen. Names SEO as a service, has a Boston-area office, active in the last 12 months, names real people, has client reviews. Guaranteed rankings or paid link schemes rule an agency out.
  2. Qualify. Proof of results, rankings for their own Boston searches, reputation, transparency, SEO depth and awards.
  3. Deep dive. For the top 10: review text, team stability on LinkedIn, and 15 AI-assistant answers.

No agency paid to be included, and none was contacted. We re-check each quarter. Send a correction · Full methodology

FAQ

Questions, answered

How much does an SEO company cost in Boston?

Only 6 of the 26 qualified Boston agencies publish a monthly SEO price. Those start between $399 and $3,000 a month, with a median of $1,375. Most agencies quote after a call.

How do I choose an SEO agency in Boston?

Ask for case studies with before-and-after numbers from businesses like yours, the contract length and exit terms, and who will do the work. Ask how links are earned and whether any result is guaranteed.

Should I hire a Boston agency or a national one?

A local team helps if you want meetings, local market knowledge or a Google Business Profile managed by someone who knows the area. Many national firms do good work, but check that the people on your account are the people you met.

How did you choose these Boston SEO agencies?

We screened 372 businesses in the Boston metro, 132 that offer SEO, and 26 that passed our screen for a local office, recent activity, named people and client reviews. We scored those on proof of results, reputation, transparency, SEO depth, team stability, AI visibility and client sentiment, and listed the top five.

Does an agency pay to be listed?

No. Nothing here is a paid placement, and we don't rank or list The Fractional SEO.
