We dug into 15 of the best WordPress SEO agencies out there so you don’t have to. Embarque, Coalition Technologies, and SmartSites are a few of the top names that stood out for their results and WordPress know-how.

Want to find the best WordPress SEO agency for you?

If you’re using WordPress and still struggling to rank, it’s not your platform—it’s your SEO. 

WordPress is insanely powerful, but it’s also easy to mess up. From clunky themes to slow load times and poor internal linking, there’s a lot that can go wrong. That’s where these agencies come in.

In this Embarque guide, we’ll review 15 top WordPress SEO agencies that understand how to turn your site into a high-performing growth engine. 

But before that…

Why listen to us?

We’ve worked with several online businesses using WordPress and trying to grow with SEO.

One example is SignHouse. When they came to us, they were getting basically zero organic traffic. Six months later, they were at 60,000 monthly visitors. That kind of growth is what we used to benchmark every agency on this list.

Why hire a WordPress SEO agency?

They actually know how WordPress works

Not every SEO agency understands the ins and outs of WordPress. A specialist agency does. They know how to deal with clunky themes, bloated plugins, slow speeds, and everything else that could be holding your site back.

You won’t get cookie-cutter advice

Generic SEO tips won’t get you very far. A WordPress-focused team will look at your actual setup and give you real fixes that work for your site. No guesswork. Just clear, practical steps you can act on.

They take the heavy lifting off your plate

Fixing technical SEO issues on WordPress can be a pain. With the right agency, you don’t have to deal with confusing dashboards or endless plugin updates. They’ll handle the messy stuff so you can focus on growing the business.

How to choose a WordPress SEO agency

Customer reviews and testimonials

The easiest way to know if an agency is worth it? See what their clients are saying. Look for honest feedback, especially ones that mention results.

For example, one of our clients, MentorCruise, saw an 800% increase in yearly revenue after working with us. Their founder tried other agencies before and said none came close to the impact we had. That kind of outcome tells you a lot more than a flashy portfolio ever could.

WordPress-specific experience

Plenty of agencies offer SEO, but not all of them understand how WordPress actually works. If they’re not familiar with things like theme structure, plugin conflicts, or how page builders affect site speed, you could end up with a slow, bloated site that never ranks. Look for a team that knows their way around WordPress—from technical setup to content formatting—so nothing holds your SEO back.

Communication and flexibility

No one wants to chase down their agency for updates. Clear communication should be the norm, not a bonus. Look for an agency that explains things in plain language, responds quickly, and adjusts easily when your priorities shift. SEO is long-term work, and if the team isn’t easy to work with, it’s going to feel longer than it needs to.

How much does a WordPress SEO agency cost?

Most WordPress SEO agencies charge anywhere from $500 to $10,000+ per month, depending on scope and expertise. If you're working with a specialist agency that knows how to rank WordPress sites properly, expect to pay on the higher end—but also expect better, faster results. Some agencies offer hourly consulting or project-based pricing, but monthly retainers are the most common.

What you’ll pay depends on a few key things:

1. Scope of work

Are you just looking for a content refresh? Or do you need technical fixes, on-page optimization, backlink building, and CRO support too? The more services you need, the more it’ll cost. Some agencies bundle this in packages, while others charge à la carte.

2. Size of your website

A 20-page blog is much easier (and cheaper) to manage than a 500+ page WordPress site with a complex structure. Bigger sites take more time to audit, optimize, and maintain—which naturally drives up cost.

3. Content volume

If content creation is part of the mix, cost usually scales with how much you need each month. Publishing one SEO post a week is a totally different ask than a full-blown content sprint with 20 pieces going live.

4. Experience of the agency

There’s a big gap between a generalist agency that dabbles in WordPress and a team that’s ranked hundreds of WordPress sites before. Higher-calibre agencies charge more—but they also tend to waste less time and produce better long-term results.
