How to Choose the Right B2B SEO Agency

When evaluating B2B SEO agencies, consider these factors:

1. Industry Experience

Look for agencies with proven experience in your specific industry. B2B SEO for SaaS is different from B2B SEO for manufacturing or professional services. Ask for case studies from similar companies.

2. Measurement Approach

The best B2B SEO agencies measure success by pipeline and revenue—not just traffic and rankings. Ask how they track conversions and attribute results to SEO efforts.

3. Content Quality

Request content samples and evaluate whether the writing sounds like a knowledgeable industry expert or generic filler. B2B buyers are sophisticated; they can spot thin content immediately.

4. GEO Capabilities

With AI search becoming more prevalent, consider whether the agency has a strategy for Generative Engine Optimization. Getting cited in ChatGPT, Perplexity, and AI Overviews is increasingly important for B2B visibility.

5. Pricing and ROI

B2B SEO agencies range from $3,000 to $25,000+ per month. Consider your deal size and customer lifetime value when evaluating whether the investment makes sense. Also consider alternatives like SEO software for agencies that can help you scale content production in-house.

FAQ

What makes B2B SEO different from B2C SEO?

B2B SEO targets decision-makers in organizations, often with longer sales cycles and multiple stakeholders. Keywords tend to be more specific and technical, content needs to demonstrate expertise, and success is measured by qualified leads and pipeline—not just traffic.

How much should I expect to pay for a B2B SEO agency?

Quality B2B SEO agencies typically charge $3,000-$25,000+ per month. Enterprise-focused agencies like Omniscient Digital start at $10,000/month, while lead-generation focused agencies like Straight North may start around $3,000/month. For a breakdown of typical pricing, see our guide on SEO packages and pricing.

How long does it take to see results from B2B SEO?

Most B2B SEO campaigns take 6-12 months to show significant results. Initial rankings improvements may appear in 3-4 months, but converting that traffic into qualified leads takes longer due to B2B's extended buying cycle.

Should I hire an agency or build an in-house team?

It depends on your resources and goals. Agencies provide immediate expertise and scalability, while in-house teams offer more control and long-term cost efficiency. Many companies start with an agency to build momentum, then transition to in-house (or a hybrid model) as they grow. Tools like Arvow can help bridge the gap by enabling smaller teams to produce agency-quality content.

What is GEO and why does it matter for B2B?

GEO (Generative Engine Optimization) is the practice of optimizing content to appear in AI-generated search results like ChatGPT, Perplexity, and Google's AI Overviews. For B2B companies, GEO matters because decision-makers increasingly use AI tools for research. Being cited as a trusted source in AI responses can significantly impact your pipeline.
