How to Choose a B2B SaaS SEO Agency

When deciding between SEO agencies, we recommend asking the below questions before deciding on a partner. These questions are crafted through our experience meeting with clients, and extensive trial and error working with clients in several B2B SaaS niches.

QuestionIdeal AnswerRed FlagsReasoning
What B2B SEO services do you provide?“We place an emphasis on thought leadership content marketing, beginning with technical SEO, keyword research, and strategic SEO planning.”“We only do technical SEO.”“We do initial keyword research and write a few blog articles each month”If you want to get the most out of an SEO campaign in terms of ROI, technical SEO and some occasional blog articles will not be enough to improve domain authority and consistently drive lead growth. 
How do you create SEO content?“We provide each client a team of specialists, including an SME, graphic designer, conversion optimizer, and analytics specialist.”“We have a team of on-staff copywriters who write for all our B2B SEO clients.”Many SEO firms have teams of writers that create cookie-cutter content for a wide variety of content, which can compromise industry authority while reaping sub-par results.
How do you measure B2B SEO results?“Our main KPI is marketing qualified leads (MQLs) or new revenue; secondary KPIs are rankings for commercially valuable keywords and traffic-to-lead conversion rate. We always strive to measure our success by our clients’ success.”“We measure success based on search ranking positions and organic traffic.”If an SEO firm only measures success by search placement and organic traffic, they will likely neglect vital SEO principles like conversion optimization essential to growing revenue.

The best SEO firms will:

  • Emphasize high-quality thought leadership content backed by a comprehensive keyword selection strategy
  • Assign a full team of experts in writing, graphic design, content strategy, and SEO analytics to ensure that they create the best SEO content possible
  • Set KPIs that directly reflect their impact on clients’ bottom lines in order to measure campaign success

If a B2B SEO firm fails to meet one of these standards, they fail to achieve significant results, stripping SEO services of the channel’s uniquely high ROI. Combined with SEO’s relatively long lead time before seeing results, clients can be left dedicating months or years to a campaign that provides subpar outcomes.
