As answered by people managing Adbassador and Diffyn.
Adbassador's answer
Every publisher on Adbassador goes through a vetting process — no PBNs, no link farms, no de-indexed sites. You see real metrics upfront (domain authority, traffic, niche) and pay transparent marketplace prices starting at $5. Most competitors either charge 2-4x markups through agency models or sell placements on low-quality networks. Adbassador cuts out the middleman.
Diffyn's answer:
Addresses workflow and change management on LLM prompts, provide teams with traceability and visualization of tests across multiple models, provide deeper understading into efficiency of these prompts.
Adbassador's answer
Three reasons: price transparency, publisher quality, and speed. You browse 800+ vetted publishers, see exactly what you're paying for, and most orders are fulfilled within 48 hours. No back-and-forth outreach, no waiting weeks for a placement. Plus, the marketplace supports guest posts, niche edits, press releases, and banner ads in one place — so you're not juggling multiple vendors.
Diffyn's answer:
Diffyn is the platform that specializes on both change management and multi-model analysis.

Adbassador's answer
SEO professionals, digital marketing agencies, freelance link builders, and SaaS companies investing in organic growth. Anyone who buys guest posts or backlinks as part of their SEO strategy — from solo consultants placing a few links per month to agencies managing dozens of client campaigns at scale.
Diffyn's answer:
Professionals incorporating LLMs or AI tools in their workflow and wants to keep track of changes and test their prompts.
Adbassador's answer
Adbassador was built out of frustration with the guest post buying process. Finding quality publishers meant hours of manual outreach, sketchy Fiverr gigs, or overpriced agency services with no transparency. We wanted a marketplace where you could browse vetted publishers, see real metrics, and place an order in minutes — the way buying anything online should work.
Diffyn's answer:
I started working on Diffyn when I notice that prompting has become an essential part of work across many industries. While there are version control platofrms like github, they are not designed for just prompt management are can be overkill such applications, it is also not integrated natively with various LLMs and relevant tools for users to validate ideas and visualise results properly.
Adbassador's answer
We don't disclose specific customer names, but our marketplace serves: - Boutique SEO agencies managing 10-50 client campaigns - Freelance link building consultants - In-house SEO teams at SaaS and e-commerce companies - Digital PR professionals placing sponsored content
