SEO agencies are critical for companies looking to make waves online. Choosing the right partner can often mean the difference between success and failure.

But who should you pick in 2025? That’s the big question, isn’t it?

Fortunately, we have answers. This post runs through the best SEO agencies for 2025 and how they differ from the other options out there.

Here’s what you need to know:

1.   Best For Multilingual SEO – Eskimoz

The best option for multilingual SEO is Eskimoz. This agency has offers in the UK, France, Germany, Spain, and Italy, with native speakers in more than 12 languages. This means that the team can provide the best marketing copy and market approach for the particular country you want to target.

Much of the SEO world currently focuses on the United States and English-speaking countries in other parts of the world. But the global market is far larger than this, with companies needing to appeal to Spanish-speaking audiences as well. That’s challenging with an English-only SEO team, but becomes much easier, Eskimoz believes, when you have multilingual support on your side.

We believe that companies operating across geographies can maximize their organic revenue using Eskimoz. The agency is able to drive performance beyond borders and help brands meet their worldwide growth targets.

2.   Best For B2B Conversions – Market Pro

Shifting gears, we think that Market Pro is probably the best option if your SEO priority is to make B2B conversions. The company believes in generating real results and spectacular ROI, boasting tens of millions of dollars in revenue generation for its clients.

Unlike some SEO agencies, Market Pro doesn’t like experiments. Instead, it prefers to use audience-driven campaigns that boost ROI and sustain interest throughout the conversion funnel.

Ultimately, the goal of Market Pro is to meet with high-intent customers with precision. The marketing agency believes in finding who these people are and targeting them relentlessly instead of adopting a more blanket approach to SEO that’s detached from revenue.

We like this approach because it means that companies are getting better value for money. Market Pro doesn’t waste its time on things that only offer marginal benefit.

3.   Best For Strategic Expertise – Wave Digital Agency

Wave Digital Agency is another standout option we think, especially if you are looking to optimize website functionality and performance. The agency’s deep technical know-how helps to get past SEO bottlenecks that might be holding your brand back, allowing you to thrive in a technical environment, even if you don’t fully understand it.

Wave operates a lean team of professionals and web development experts who work closely with you to solve your technical SEO issues. The underlying team is ambitious and performance-driven, which is one of the reasons why they’ve become so popular over recent years. Their goal is to improve customer acquisition and ensure that they boost your conversion rates.

We liked that they had a free audit we could use. This told us what was wrong with our website and what we needed to do to improve it.

4.   Best For Affordability – Legiit

Coming in at number 4 in this review is Legiit. This agency prides itself on offering some of the lowest-cost SEO services around, including backlinks, by reducing markups.

Legiit is able to keep its costs low because it uses freelancers. This approach means that it can build out elements of your SEO strategy at low cost, preventing them from getting in the way financially. We also like how the brand offers inexpensive SEO courses and services for low prices directly on its website, giving you more options and allowing you to trial it before you buy any longer-term options.

The downside, of course, is that you have to use the platform to find SEO professionals who may not be affiliated with the company. This reality means you need to be careful who you select and do your own due diligence.

5.   Best For Professionalism – Coalition

Coalition Media is one of the top choices out there for firms looking for professionalism and to avoid using amateurs. This firm prides itself on offering the highest level of service to its clients as possible, helping them succeed online with proven methods.

So far, the company’s achievements are significant, and we can personally voice for them. For example, it’s been able to generate over 25 million monthly visitors for its clients in the time that it’s been operational, and generate an incredible 20 million ecommerce transactions in that time. It’s also able to help qualify leads and focus more on the sales pipeline, compared to a lot of SEO agencies out there.

Critically, the agency doesn’t do any guesswork with its SEO. Instead, it develops them around scientifically-tested data, making them even more effective in the long-run.

6.   Best For Getting To Page One On Google – First Page Sage

Finally, you might consider First Page Sage in 2025, one of the top SEO firms in the US, which prefers to focus on organic marketing. This agency was founded in 2009, which is a long time ago for an SEO firm, and specialises in thought leadership and content marketing. Its team has a high level of average experience, and it remains led by its founder today.

This pedigree means that First Page Sage is able to build content like it was written by your own in-house team. It has gigantic experience of complex industries and uses this knowledge to drive forward more bespoke services, allowing it to meet your business where it is at right now, without endless revision rounds.

These insights then lead into the company’s ability to produce great work that gets your brand to the top position of search results. Being authoritative is helpful for ranking on Google.

Final Verdict

So there you have it: our roundup of some of the best SEO agencies in 2025. Our top pick was Eskimoz because of the sheer versatility it offers and the fact that it can produce content for multiple countries by native speakers.
