Grow and Convert, founded in 2015 by Benji Hyam and Devesh Khanal, is one of the most philosophically distinctive content marketing agencies operating today.

Their team — composed primarily of former journalists, researchers, and in-house content leaders — produces long-form content for the most respected brands in B2B technology, including Google, Amazon, Zendesk, and Intercom. Animalz built its reputation on the conviction that the best-performing SEO content is also the most genuinely useful content — a philosophy that has proven especially resilient in an era of AI-generated content and algorithmic volatility.

How to Choose the Right SEO Content Marketing Agency
Start with Best For — match the description to your business model, content maturity, and primary growth objective before evaluating anything else.
Then check Core Expertise against the specific content capability you actually need: bottom-of-funnel conversion content, thought leadership and brand authority, high-volume content production, or eCommerce product discovery optimization. These are distinct skill sets with meaningfully different outputs — and not every agency excels at all of them.
Use Pricing as your floor, not your ceiling — final retainers always depend on content volume, production complexity, and the scope of SEO strategy included. Monthly retainers suit brands building sustained organic authority through consistent publishing; project-based engagements suit defined content audits, site migrations, or launch-phase content programs.
