Buying guide

Choosing a B2B SEO agency

B2B buyers search less often, but each search can be worth a lot. A B2B SEO agency should understand long sales cycles, buying committees and content that helps a shortlist, not just traffic.

Ask how they connect organic search to pipeline: leads, demos and revenue in your CRM, not just sessions. Look for experience in your kind of product and with technical subject matter, because thin content won't persuade experienced buyers.

Questions to ask

  • How do you connect SEO to pipeline in our CRM?
  • Who writes the content, and how technical can it get?
  • Have you worked with products like ours?
  • How long before we should see leads?
