START WITH THE BRIEF

What kind of SEO help do you need?

SEO can mean a technical repair, a sustained content program, or a clearer route from search to customers. Look at the work your site needs before comparing agencies by rankings alone.

Compare technical skill, editorial quality, implementation ownership, and how organic work connects to qualified demand.

THE DIRECTORY, WITH CONTEXT

A closer look at each agency

Each profile below explains the agency's broader specialty, where it may fit, and what to ask before hiring.

BearFox Marketing

Specializes in paid advertising, social media, and SEO

Consider for: A service business with active search and ad spend but no shared definition of a qualified lead. Bring channel access and a baseline for inquiries and sales.

Why included: Search, paid advertising, and social can be planned around one acquisition goal, with lead or sale quality checked across channels. Visit the agency website ↗

Before hiring: Consider it when search and paid campaigns need to work from the same acquisition plan. Ask for a recent example in your market and how the team measures leads or sales beyond traffic.

Grow and Convert

Specializes in content strategy, search, and promotion

Consider for: A company with a defined customer and conversion event, enough product knowledge to support interviews, and a need to connect content to leads or sales.

Why included: Offers managed SEO research, content, technical support, and measurement. See the agency example ↗

Before hiring: Consider it when a content program needs to connect search queries to leads and customers. Ask how it chooses topics, attributes conversions, and updates articles after launch.

Omniscient Digital

Specializes in SEO strategy with content production and development for B2B software companies

Consider for: A SaaS team with clear product positioning, access to subject experts, and patience to build search visibility across a full buying journey.

Why included: Runs SEO strategy and content programs for B2B brands, with search work tied to pipeline. See the agency example ↗

Before hiring: Worth comparing for a SaaS team with the product knowledge to support a sustained content program. Ask who owns technical SEO, editorial review, and the path from content to pipeline.

SimpleTiger

Specializes in SEO and content marketing for software companies

Consider for: A software company with a defined category and subject experts that can commit to sustained publishing and measure organic pipeline over time.

Why included: Specializes in SEO and search-led growth for SaaS and AI companies. See the agency example ↗

Before hiring: Worth exploring when search can reach buyers during research and comparison. Ask how technical fixes, content production, and lead-quality reporting are divided.

Growth Marketing Pro

Specializes in SEO, paid media, content, CRO, and growth marketing for technology companies

Consider for: A technology business with a defined revenue goal but gaps between traffic, conversion, and reporting, willing to prioritize the highest-loss stage.

Why included: SEO, paid media, content, conversion work, and marketing operations can link technology demand generation to the systems that record it. Visit the agency website ↗

Before hiring: Consider it when a technology business needs search and acquisition work tied to commercial goals. Ask for current service scope, recent comparable work, and who will own execution.

Brenton Way

Specializes in growth marketing agency for scaleups and midsize brands

Consider for: A brand with an established product, customer data, and several connected growth needs that wants a senior team to plan and run the work together.

Why included: Brenton Way combines growth strategy, performance media, search, creative, conversion, and retention for scaleups and midsize brands. Visit the agency website ↗

Before hiring: Compare it when you need a senior team to plan and run several connected growth channels. Ask which work would happen in the first quarter, who would lead the account, and how business results would be measured.

BEFORE YOU CHOOSE

Questions worth taking to a first conversation

Relevant work: Ask for a recent project that resembles your brief and learn what the agency actually delivered.
The proposed team: Meet the people who would do the work and ask what they would focus on first.
Scope and results: Ask for relevant search work, technical audit examples, a content plan, and how outcomes are reported.
Costs: Clarify fees, outside production or software costs, and what happens after launch.

ABOUT THIS LIST

How this list was assembled

These agencies have directory profiles or linked agency work relevant to SEO. We looked at their stated services, specialties, and available examples to explain what each team may suit. The list is presented in no particular order. A published case can show the work an agency describes, but its results still need to be discussed with the team.

Every agency has a named reviewer in the directory record. The certificate confirms directory inclusion and review attribution; it does not verify an agency's results. Read our editorial standards and each full profile for more context.
