"Not published" means the agency does not list a retainer. ## How to choose a B2B SEO or content agency Ask what they will be measured on in six months. Traffic, rankings, AI citations, and pipeline are different reports. A content team that cannot see your CRM will optimize for the first one. - Ask for two B2B examples with the same sales cycle length as yours. - Ask who writes, who edits, and whether subject-matter interviews are in the fee. - Ask how technical recommendations get implemented, and by whom. - Separate content production from digital PR and from paid media. - If you need the site rebuilt, hire a design studio as well, or pick an agency that does both and price that scope. ## Related lists The site itself is on [B2B web design and brand agencies](https://getaob.com/b2b-web-design-agencies).

Book a call ## B2B SEO and content FAQ ### What are the best B2B SEO and content agencies? Animalz, Omniscient Digital, Grow and Convert, and Siege Media are content and organic agencies used by B2B software companies. iPullRank handles technical and AI search on complex sites. Foundation focuses on AI visibility for B2B tech. Seer Interactive and Orbit Media cover search alongside paid or web work. Directive and Kalungi are full-service B2B agencies that include content. Retainers are quoted. ### How much does a B2B content agency cost? The agencies on this list do not publish a single retainer we are willing to repeat without their current proposal. Ask for the monthly minimum, how many pieces that buys, whether digital PR is included, and what happens if your team is slow to publish. ### What is the difference between an SEO agency and a content agency? An SEO agency is accountable for technical health, indexation, and the search program. A content agency is accountable for the pages. Several firms on this list sell both, because a draft that never gets the technical basics right does not get found. Ask which team does which. ### Do these agencies also handle AI search? Omniscient Digital, Grow and Convert, Siege Media, iPullRank, Foundation, and Seer all describe AI-answer or GEO work on their current sites. The methods differ. Ask how they measure a citation, and what they will do if the citation never turns into a lead. ### Does OneGTM offer SEO or content services? No. OneGTM builds outbound and CRM systems. The agencies on this page do search and content. Content is producing leads and they are dying in an inbox? ## Related - [Best B2B web design agencies](https://getaob.com/b2b-web-design-agencies): B2B web design and brand studios for marketing sites and product interfaces. - [Best AEO tools](https://getaob.com/aeo-tools): AI search visibility trackers and the SEO tools behind them, with pricing and how to do AEO in practice. - [Best content creation tools](https://getaob.com/content-creation-tools): Writing, design, video, and repurposing tools for B2B founders and marketing teams, with pricing. - [Best B2B paid media agencies](https://getaob.com/paid-media-agencies): LinkedIn, Google, and paid social agencies for B2B SaaS, with published fees and how to pick one. - [Best case study writing agencies](https://getaob.com/case-study-agencies): Agencies and tools for written and video B2B customer stories, with published prices and what a good case study contains. - [Best LinkedIn ghostwriting agencies](https://getaob.com/ghostwriting-agencies): LinkedIn ghostwriting agencies and tools for founders, with pricing and how to turn post engagers into pipeline. - [Best fractional CMO firms](https://getaob.com/fractional-cmo): Fractional CMO firms, networks and marketplaces for B2B startups, with published fees and how to pick one. ## Get an outbound system review Tell me what you're building.
