10 Best SEO Agencies To Drive Revenue

If you’re looking for an SEO agency, there are three criteria you need to consider:

1. Proven results in your niche: the more niche your business is, the more necessary that you find a niche agency. All SEO agencies have a certain “type” of clients that they serve. Some SEO agencies work primarily with local businesses, some only work with SaaS, some only work with startups. Always ask whether they’ve driven organic growth for businesses like yours (B2B vs. B2C, local vs. global, competitive vs. emerging markets) during your Discovery Call.
   
2. Process and transparency: A good agency can clearly explain how they do SEO: research, content strategy, technical fixes, link building, reporting, etc. They should be able to explain SEO terms to you in simple language. SEO at its core is really simple, and SEO agencies shouldn’t over-complicate it.
   
3. Strategic thinking: you’d want to work with a strategic SEO agency who cares about the long-term, sustainable growth of your business rather than quick-win tactics. The right SEO agency understands your business model, funnels, and buyer intent, and then ties all of their SEO efforts to actual business goals like leads, product sign-ups, business opportunities, etc.

Types of SEO agencies

From my experience hiring, working with, and building an SEO agency, I think there are three major types of SEO agencies:

1. General SEO agencies: These agencies only do SEO, but they serve everyone: all verticals, all industries, all niches. This allows them to gain an incredibly broad and diverse perspective about the SEO world as a whole, but that also means they may be a Master of None. These agencies are better suited for small, local businesses, or businesses in a predictable industry.
2. Niche SEO agencies: These SEO agencies specialize in a specific type of client such as SaaS, HVAC, or law firms. Their advantage is deep industry expertise that generalist SEO agencies can’t match. Because their processes are built around your exact market, they’re especially effective for technical fields like engineering, law, healthcare, and software.
3. Full-service agencies: These are better described as digital marketing agencies. They offer SEO alongside services like web development, PPC, video production, and email marketing, making them ideal for businesses that want a full marketing department under one roof.

Think of high-intent content like:

These are the types of content that gets shared in dark socials (private Slack channels, LinkedIn messages, tool discussion meetings, etc.).

FAQ about choosing an SEO agency?

1. How much should companies budget for SEO services?

It depends A LOT on your goals, competition, and whether content creation is included, but here’s a general guidelines:

• If you’re just a very small local business with one location, SEO costs may range from $500-$1,000/month, although we generally don’t advise you go with any SEO services below $1,000 if you want decent results.
• If you’re a local business wanting to rank for many locations, SEO costs may range from $1,000-$2,000/month.
• If you’re a more established company, selling entirely online, with an international client base, SEO costs may range from $3,000 to $5,000/month.
• If you’re in SaaS, SEO costs along with content creation may range from $5,000-$7,500 for starter packages.
• If you’re in B2B SaaS, with established online presence, and want to compete with bigger players, SEO costs can go from $7,500 to $10,000.

2. Why is SEO important?

SEO is a stable, scalable growth channel. Unlike paid ads, which stop generating leads once spending ends, SEO continues driving traffic and leads over time and reaches buyers early in their research process.

3. What results can I expect from an SEO agency in the first year?

In the first year, many companies see 50–200% growth in organic traffic and begin generating 20–50 qualified leads per month, depending on the industry and starting point.

4. Can an SEO agency help with competitor analysis?

Yes. Strong SEO strategies start with deep competitor analysis to identify what’s working, which keywords drive results, and where gaps exist.

5. Is SEO better for startups or established companies?

SEO works for both. Startups often use paid ads for quick traction, then invest in SEO for long-term growth. Established companies benefit even more, especially if competitors haven’t invested heavily in SEO yet.

6. How do SEO agencies measure success beyond traffic?

The best SEO agencies track:

• Qualified leads
• Conversions
• Pipeline impact
• Revenue attribution

Traffic and rankings matter, but revenue impact is the ultimate measure of success.
